EXECUTIVE SUMMARY
This report presents the results and conclusions of the final survey conducted by PortlandGeneral Electric Company of the Main Steam Support Structure, Electrical Penetration Area, andSteam Generator Blovdown Building (MSSS/EPA/SGBB), which are located immediatelyadjacent to the Trojan Nuclear Plant Containment Building. Plant systems and components wereremoved and contaminated structural surfaces remediated as part of the decommissioningprocess. A final survey of the equipment and structural surfaces remaining in theMSSS/EPA/SGBB was performed. Final survey data collection began in June 2003 and wascompleted in September 2003.
The final survey was performed in accordance with the final survey process described inPGE-1061, "Trojan Nuclear Plant Defueled Safety Analysis Report and License TerminationPlan (PGE-1078)," referred to as the LTP. The equipment and structural surfaces in theMSSS/EPA/SGBB were divided into 20 survey units, encompassing 5,443 square meters ofsurface area, and classified according to their potential for containing residual radioactivity.Eleven survey units were classified as Class 1, five survey units as Class 2, and four survey unitsas Class 3. Survey data were collected from each survey unit according to data collectionpatterns and frequencies established for each classification. Scan measurements wvere performedover approximately one-third of the entire surface area and a total of 640 static measurementswere collected as final survey data. In addition, 640 supplemental removable surfaceradioactivity measurements were collected.
The final survey data demonstrate that each survey unit meets the radiological criteria forunrestricted use specified in 10 CFR 20.1402. Based on the results of the final survey, PortlandGeneral Electric Company concludes the MSSS/EPA/SGBB meet the regulatory requirementsfor release to unrestricted use.
The MSSS/EPA/SGBB were some of the first areas on the plant site to undergo remediation.Early remediation activities preceded the LTP by several years and were performed under theassumption that, for ALARA purposes, detectable levels of radioactivity had to be removed. Asa result, areas with low levels of detectable radioactivity were remediated. Later, these areas,classified as Class 2 under the LTP, would not have been remediated since pre-remediationlevels of radioactivity were below the radiological criteria for unrestricted use. Due to the lowlevels of radioactivity, these areas would not have been remediated for ALARA purposes, either.

1. INTRODUCTION
1.1 PURPOSE AND SCOPE
This report presents the results and conclusions of the final survey of the Main Steam SupportStructure, Electrical Penetration Area, and Steam Generator Blowdown Building(MSSS/EPA/SGBB). It provides the information required by 10 CFR 50.82(a)(1 1), whichdemonstrates that the MSSS/EPA/SGBB meet the radiological criteria for unrestricted usespecified in 10 CFR 20.1402. This report also documents the final survey was performed inaccordance with the final survey process described in PGE-1 061, "Trojan Nuclear PlantDefueled Safety Analysis Report and License Termination Plan (PGE-l 078)," hereinafterreferred to as the LTP.
1.2 DESCRIPTION
The MSSS/EPA/SGBB, shown in Figure I-1, are found near the center of the industrial portionof the plant site, adjacent to the Trojan Nuclear Plant Containment Building, and are surroundedby the Auxiliary, Control, and Turbine Buildings. Their respective surface areas are shown inthe following table.
Surface Area
Surfaces Area (M_)
Main Steam Support Structure 2,127Electrical Penetration Area 3,031Steam Generator Blowdown Building 285
Total Surface Area: | 5,443
The Main Steam Support Structure (MSSS) is located between the Containment Building and theTurbine Building and provided protection and support for the main steam isolation, power-operated relief and safety valves, as well as main steam and feedwater piping. The structure isconstructed of reinforced concrete and structural steel.
The Electrical Penetration Area (EPA) is located north of the MSSS between the Containment,Control, and Auxiliary Buildings and housed Containment electrical penetrations. The EPA isconstructed of reinforced masonry block and concrete.
The Steam Generator Blowdown Building is located south of the MSSS between theContainment Building and the Turbine Building and housed steam generator blowdown systemcomponents such as the blowdown tank, pump, and heat exchanger. The building is constructedof reinforced masonry block and concrete.
The MSSS/EPA/SGBB were prepared for final survey by a series of decommissioning activities,including radiological characterization, dismantlement and demolition, remediation, and turnoverto final survey. A general description of these activities is given in Appendix A. Detaileddecommissioning information as well as a brief radiological history is contained in the LTP,
I-I
TROJAN FINA L SU JRV'EY REPORT- ALNSI/FPM/IGRR
Section 3. Radiological characterization data were gathered and analyzed. The results guideddecisions regarding the need for, extent of, and most effective means of remediation.Contaminated structures, equipment, and components were dismantled or demolished andremoved for disposal. Remaining structural surfaces were remediated, as needed, and thensystematically turned over for final survey. An assessment of the operating and radiologicalhistory established the initial classification of MSSS/EPA/SGBB areas. In their post-final surveyconfiguration, the MSSS/EPA/SGBB exist primarily as bare concrete, masonry block, and steelstructural surfaces.
1.3 SITE RELEASE CRITERIA
The site release criteria applied to the final survey of the MSSS/EPA/SGBB correspond to theradiological criteria for unrestricted use given in 10 CFR 20.1402, which are:
1. Dose Criterion: The residual radioactivity that is distinguishable from backgroundradiation results in a Total Effective Dose Equivalent (TEDE) to an averagemember of the critical group that does not exceed 25 mremlyr, including that fromgroundwater sources of drinking water; and
2. ALARA Criterion: The residual radioactivity has been reduced to levels that areas low as reasonably achievable (ALARA).
1.3.1 APPLICATION OF THE SITE RELEASE CRITERIA
Levels of residual radioactivity that correspond to the allowable radiation dose and ALARAlevels of the site release criteria were derived by analysis of various scenarios and pathways(e.g., direct radiation, inhalation, ingestion) through which exposures could occur. These derivedlevels, referred to as Derived Concentration Guideline Levels (DCGLs), form the basis for thefollowing four conditions which, when met, satisfy the site release criteria:
1. The average residual radioactivity above background is equal to or below theDCGL;
2. Individual measurements, representing small areas of residual radioactivity whichexceed the DCGL, do not exceed the elevated measurement comparison DCGL;
3. Where one or more individual measurements exceed the DCGL, the averageresidual radioactivity passes the Sign statistical test; and
4. Remediation is performed where it is ALARA to reduce the levels of residualradioactivity to below the concentrations necessary to meet the DCGLs.
The manner in which these conditions were met is described in Section 4.2.

1.3.2 DERIVED CONCENTRATION GUIDELINE LEVEL
The residual radioactivity concentration levels on equipment and structural surfaces remaining inthe MSSS/EPA/SGBB were compared to a gross activity DCGL of 21,000 dpm/100 cm2 , withthe exception of a relatively small area in the EPA. This exception is addressed in Appendix B.The gross activity DCGL was derived for surface residual radioactivity and developed using themethodology described in the LTP, Section 4.2.3, based on the radionuclide-specific screeningDCGLs given in the LTP, Table 4-1.
Samples were collected from representative systems, structures, or components associated withthe secondary system where the radioactivity detected would be due to primary system leakageinto the secondary system. The samples were used to establish the radionuclide distribution ofsurface residual radioactivity. The samples were sent to an offsite laboratory for analysis and thelaboratory results were used to calculate a gross activity DCGL value for each sample.
Several radionuclides of interest were detected in each of the samples. The single radionuclidedetected in all the samples was 137Cs. It accounted for the highest activity concentration, rangingfrom 83 to 99% of the total activity, in all but one of the samples. In that one sample, 63Ni hadthe highest activity concentration and 137Cs accounted for only 31% of the total activity. For allsamples, alpha emitters were either not detected by sample analysis or were detected at activityconcentrations that are insignificant in terms of dose contribution.
For purposes of calculating the DCGL, radionuclides of interest that were not detected wereassumed present at their minimum detectable concentration (MDC). They were included in theDCGL calculation where their MDC exceeded 10% of their respective screening DCGLs. Therewas some variability in relative radionuclide fractions when one sample was compared to
2another. Therefore, the most conservative calculated value, 21,000 dpm/1 00 cm , was selectedas the gross activity DCGL. The radionuclide distribution assumed for this DCGL is shown inthe following table.

Activity Fraction/DCGL values for all the radionuclides.

2. FINAL SURVEY DESIGN
The final survey was designed and performed as described in the LTP, Section 4. The DataQuality Objectives (DQO) process was used to ensure that the final survey results were ofsufficient quality to support the final decision. The MSSS/EPA/SGBB were divided into surveyunits of proper size, which were categorized and classified according to the type and potential ofresidual radioactivity. Instrumentation and survey methods, appropriate to the type of radiationbeing measured, were used to collect scan, static, and supplemental measurements. Themeasurements were collected in accordance with administrative and quality controls instituted toprovide assurance of accurate results.
2.1 SURVEY UNITS
The MSSS/EPA/SGBB were divided into 20 survey units based on the physical characteristics,the potential for elevated residual radioactivity, and the size of the area with similar potential forresidual radioactivity. The survey units were categorized as structures with surface residualradioactivity, where the building occupancy dose model is applied.
2.1.1 CLASSIFICATION
Survey units were classified as Class 1, Class 2, or Class 3 based on the potential for residualradioactivity. Areas with residual radioactivity that exceeded the DCGL prior to remediationwere divided into 11 Class I survey units. Areas with residual radioactivity detectable abovebackground levels, but that did not exceed the DCGL prior to remediation, were divided into fiveClass 2 survey units. Areas with residual radioactivity not expected to be detectable abovebackground levels were divided into four Class 3 survey units.
The classification process incorporated the working hypothesis that all areas had a potential forresidual radioactivity above the DCGL. This initial assumption meant that a survey unit wasinitially considered Class I unless a basis for classification as Class 2 or Class 3 was identified.Early in the final survey planning process, little or no characterization data were available.Elevated radiation levels from contaminated surfaces, components, and equipment prevented thecollection of meaningful radiological data. Some surfaces were physically inaccessible. Duringthe course of decommissioning, the contaminated components and equipment were removed,surfaces were made accessible and remediated, and a substantial amount of characterization datawas collected. The data, summarized in Table 2-1, showed that these areas could be properlyclassified as Class 2 or Class 3. This approach was consistent with that described in the LTP, inwhich areas arc initially considered Class 1 areas unless a basis for classification as Class 2 orClass 3 is identified. Both scan and static measurement data collected during final surveyconfirmed the classification decisions made.
2.1.2 SURVEY UNIT SIZE
The MSSS/EPA/SGBB were divided into survey units ranging in size from 45 to 970 M2 .
Survey units were sized to ensure that survey data points were relatively uniformly distributedamong areas of similar potential for residual radioactivity. Survey units were designed to have
2-1
TROJAN FIN AL IR UEFY REPORT - ASSS'FPA /SGRR
relatively simple shapes unless an unusual shape was appropriate for the operational history ofthe area. Where possible, existing building characteristics such as horizontal and verticalstructural supports, walls, and rooms were used to define the boundaries of the survey units.
Class I survey units were limited to no more than 100 m2 floor area; Class 2 survey units to nomore than 1,000 m2 floor area. Class 3 survey units were limited by practical considerations.
2.1.3 IDENTIFICATION NOMENCLATURE
Each survey unit was identified by a seven-digit identification code. The first digit represents thesurvey unit category. A single category code, S, for structure with surface residual radioactivity,was used. The next two digits represent the reference map identification code. For theMSSS/EPA/SGBB, "18" was used. The next three digits represent the plant elevation. Wherethe survey unit was other than a floor surface, this number represents the plant elevation fromwhich the survey unit was accessed. The last digit is an alpha sequential survey unit designatorthat wvas assigned in sequential order of the survey unit being created. The following figureillustrates the survey unit identification code for the 2nd survey unit beginning at Elevation 59' ofthe MSSS/EPA/SGBB.

2.2 INSTRUMENTATION
Portable and laboratory instrumentation capable of detecting the radiation types and energies ofinterest were selected, calibrated, and maintained for final survey data collection. Commerciallyavailable radiation detection and measurement instrumentation wvas selected based on reliableoperation, detection sensitivity, operating characteristics, and expected performance in the field.Radioactive sources used for calibration purposes are traceable to the National Institute ofStandards and Technology (NIST) for both Trojan and vendor operations.
2.2.1 PORTABLE INSTRUMENTATION
Scan and static surface radioactivity measurements were performed using the Ludlum Model2350-1 data logging survey meter with one of two types of Ludlum detectors: gas-flowproportional (GFP) or Geiger-Mueller (G-M). The following table gives the model number anda description of the detectors used.

2.2.1.1 Calibration and Maintenance
Survey instruments were calibrated for the radiation types and energies of interest. Thefollowing table provides typical information on the calibration sources used.

Radionuclide mixture ratios and varying energies were accounted for during calibration by usinga calibration source with a conservative average energy as compared to the weighted averageenergy of the radionuclide mixture.
A total efficiency was established for GFP and G-M detectors used to survey the smoothsurfaces. The total efficiency is the product of the instrument efficiency and the source (orsurface) efficiency for a specified survey geometry or measurement technique. The instrumentefficiency, i.e., the ratio between the net count rate of the instrument and the 27r surface emissionrate of a radiation source, was determined by counting the source with the detector in a fixedposition from the source (reproducible geometry). A jig was used to create the reproducible

geometry and a source to detector distance of 1 cm was normally used. A value of 0.5 was usedfor the source efficiency for smooth surfaces; a value of 0.3 for concrete scabbled surfaces.These values were established based on beta energies of the expected radionuclide distributionand on surface geometry considerations. The source efficiency for beta particle emission is theratio between the number of radiation particles emerging from the measurement surface of thearea being surveyed (the source) and the total number of radiation particles being released withinthat source per unit time.
2.2.1.2 Instrument Response
Instrument response was checked before and after instrument use each day. A check source wvasused that emitted the same type of radiation (i.e., beta and/or gamma) as the radiation beingmeasured and that gave a similar instrument response (see the preceding table). The responsecheck was performed using a specified source-detector alignment that could easily be repeated.If the instrument failed its response check, it was not used until the problem was resolved.Measurements made between the last acceptable response check and the failed check wereevaluated and, if appropriate, discarded.
2.2.1.3 Minimum Detectable Concentration
A minimum detectable concentration (MDC) was determined for each instrument and scan andstatic measurement method that were used for survey data collection. Instruments used for scanmeasurements were capable of detecting radiations of interest to an MDC of less than 50% of theDCGL at a scan rate of 5 cm/sec. Instruments used for static measurements were capable ofdetecting radiations of interest to an MDC of less than 15% of the DCGL with a count time ofone minute.
2.2.2 LABORATORY INSTRUMENTATION
On-site laboratory instruments were used to perform gas proportional counting of removablesurface radioactivity samples (smears). Removable surface radioactivity measurements wereperformed using the Tennelec Model LB 5100 GFP alphalbeta counting system described in thetable below.

2.2.2.1 Calibration and Maintenance
The Tennelec Model LB5 100 wvas calibrated for the radiation types and energies of interest bycounting a radionuclide standard and comparing the results with the actual concentration on thecertificate of calibration provided by the manufacturer of the radionuclide standard. Thefollowing table provides typical information on the radionuclide standards used.

2.2.2.2 Daily Quality Control Standardization
Quality Control (QC) standardization was performed on the Tennelec Model 5100 prior to useeach day. A QC standard wvas used that emitted the same type of beta radiation in the same typeof counting geometry as the radiation being measured. Count results were graphed andreviewed for trends in detector performance. No count results fell outside the acceptable QCband and no negative trends were identified in instrument performance.
2.2.2.3 Minimum Detectable Concentration
The Tennelec Model 5100 was capable of detecting radiations of interest to less than 1% of theDCGL with a two minute count time.
2.3 SURVEY METHODS
Survey methods, as described in the following sections, were applied to collect scan and staticmeasurements of surface residual radioactivity, and removable surface radioactivitymeasurements from structural surfaces.
2.3.1 SCAN MEASUREMENTS
Scan measurements wvere performed to locate radiation anomalies that might indicate elevatedareas of residual radioactivity that require further investigation. The level of scan coverage wasproportional to the potential for finding elevated areas of residual radioactivity based on thehistory of the survey unit.
Where no remediation had occurred, inaccessible surfaces (e.g, inside cracks or small borepenetrations) were assumed to have the same level of residual radioactivity as that found onadjacent accessible surfaces. Accessible surfaces were surveyed the same as other structuresurfaces. Where remediation had occurred, an approximation of the residual radioactivity on the
2-5
TROJ1N FWNA . STURV'FYREPORT- A41SSSEPA/SGRR
inaccessible surface was made and the accessible surfaces were surveyed the same as otherstructure surfaces except that they were included in the scan coverage area when scanning wasdone at less than 100% coverage (i.e., Class 2 survey unit).
2.3.1.1 Scan Coverage
Scan measurements of Class I survey units were performed over 100% of the surface area. Scanmeasurements of Class 2 survey units were performed over 20% of the surface area. For Class 3survey units, scan measurements were performed over 5 to 10% of the surface area. In Class 2and Class 3 survey units, those areas with the highest potential for elevated residual radioactivity(e.g., walkways, comers, remediated surfaces), based on professional judgment, were selectedfor scanning. The percent of scan coverage was determined based on the number and size of theselected areas.
2.3.1.2 Surface Residual Radioactivity
Structure surfaces were scanned for beta-gamma emitting radionuclides. Typically, the detectorwas held less than 2 cm from the surface and moved at 5 cm/sec over an area of one squaremeter. Once the selected area was scanned, the latched value was electronically entered into thedata logger memory.
Normally, the Ludlum Model 43-68 GFP detector with the data logger in ratemeter latchingmode was used. For areas with size or geometry constraints, the Ludlum Model 44-9 pancakeG-M detector wvas used.
Structure surfaces were not scanned for alpha-emitting radionuclides. Radiologicalcharacterization data indicated that alpha emitters were either not present or were present atactivity concentrations that were insignificant in terms of dose contribution. Therefore, alpha-specific measurements of surface residual radioactivity were not performed.
2.3.2 STATIC MEASUREMENTS
Static measurements were collected at a frequency and at representative locations throughout thesurvey unit such that a statistically sound conclusion regarding the radiological condition of thesurvey unit could be developed.
2.3.2.1 Surface Residual Radioactivity
Static measurements to detect beta-gamma emitting surface residual radioactivity on structureand plant system surfaces were normally collected using the Ludlum Model 43-68 GFP detectorwith the data logger in scaler mode. For areas with size or geometry constraints, the LudlumModel 44-9 pancake G-M detector was used. For each discrete measurement, the detector wasplaced on or near the surface to be measured, a one-minute count was taken, and the value waselectronically entered into the data logger memory.

TROJAN FINAL SL IR VF Y REPORT- AISSSVEPA4SGRS
2.3.2.2 Number of Measurements
To simplify the final survey process and to ensure conservatism without an associatedunreasonable expenditure of resources, a minimum number of 30 static measurements per surveyunit were collected. This number of measurements provided a sample population of sufficientsize to assure statistical confidence in the conclusions drawn from the survey data (seeSection 4.1.3.3).
2.3.2.3 Measurement Locations
Measurement locations in Class 1 and Class 2 survey units were selected using a random-startsystematic spacing method based on a reference coordinate system appropriate for the surveyunit. Scale drawings, maps, or photographs of the survey unit were prepared, along with anoverlay of the reference coordinate system. A random number generator provided thecoordinates of the starting point. Subsequent measurement locations were distributed around thestarting point in a systematic pattern across the survey unit area. In some cases, this led to morethan the minimum number of 30 static measurements being collected.
For Class 3 survey units, measurement locations were selected using the random selectionprocess (i.e., the reference coordinate system and a random number generator). A randomnumber generator provided the coordinates of each measurement location.
Measurement locations that did not fall within the survey unit area or that could not be surveyeddue to health and safety considerations were replaced with other measurement locationsdetermined using the random selection process.
2.3.3 SUPPLEMENTAL MEASUREMENTS
Supplemental measurements to detect removable beta-gamma emitting surface residualradioactivity on structure surfaces were collected at static measurement locations. Thesemeasurements (i.e., smears) were collected to verify removable surface radioactivity was nomore than 10% of the gross activity DCGL. Smears were counted in the laboratory using theTennelec Model LB5100.
2.3.4 MEASUREMENT LOCATION IDENTIFICATION
Measurement locations were clearly identified and documented to ensure they could be relocatedif necessary. Actual measurement locations were permanently marked in the field and on surveymaps. A unique number identifies each measurement location. The number convention,described in Section 2.4.4, allows survey data to be referenced to specific measurement locationsidentified on the photographs, drawings, or maps of the survey unit.
Physical gridding was used where practical and useful. It provided a mechanism for referencingscan measurements to a specific location. Permanent marker was used to mark the physical gridlayout. The basic grid pattern used was a one-meter square grid.

2.4 SURVEY PERFORMANCE
2.4.1 SAMPLE HANDLING
Smear samples collected for laboratory analysis were tracked. When sample custody wastransferred (e.g., when samples were sent to the lab for analysis), a sample tracking recordaccompanied the sample for tracking purposes. The sample tracking (or chain of custody) recorddocumented the custody of samples from the point of collection until final results were obtained.
2.4.2 DATA INVESTIGATION
Locations, identified by scan or static measurements, with residual radioactivity that exceededthe DCGL were marked and investigated. Scan measurements were performed over 100 percentof the area being investigated. Static measurements in the form of scalar or integrated countswere performed at locations with the highest concentration of residual radioactivity. A postingplot was also generated to document the area investigated and the levels of residual radioactivityfound.
Three investigations were performed. The results of the data investigations are summarized inTable 3-2. The details of the investigations are included in survey unit summary reports (seeAppendix C). Depending on the results of the investigation, the identified areas within thesurvey unit were remediated and resurveyed, or the elevated measurement comparison wasapplied.
2.4.3 DATA RECORDING
Measurement data were corrected for instrument efficiency, source efficiency, detector area, andmeasurement size as applicable, and recorded in units appropriate for comparison to the DCGL.The recording units were dpmll 00 cm2. Measured numerical values were recorded and includedvalues below the MDC. Instrument and material backgrounds were not subtracted from residualradioactivity measurements gathered using portable instrumentation. Instrument backgroundNvas subtracted from measurements analyzed using laboratory instrumentation.
Measurement results stored as final survey data constitute the final survey of record and areincluded in the data set for each survey unit. The data were used for calculations to determinecompliance with the site release dose criterion. The affected data were stored as characterizationdata where a survey unit was remediated and/or reclassified during final survey.
2.4.4 DATA MANAGEMENT
The Survey Data Management System (SDMS) wvas used to store and process survey data. TheSDMS is an electronic database that contains the final survey data and constitutes the qualityrecord. Administrative controls for maintaining data integrity were incorporated into thesoftware design. SDMS applications were tested as part of two separate tests: factory acceptancetesting performed by the vendor and site acceptance testing performed by the Final Surveyorganization. A test plan and procedure were developed and documented for each functional
2-8
TRO. IV FIN'AL, RSR1VFY REPORT- AIS.SS/EPAISGRB
module. Documented test results include the acceptance test objectives, test results, testdiscrepancies, and corrective actions taken to resolve the discrepancies.
Raw survey data captured in the Ludlum Model 2350-1 data logger were downloaded,electronically converted to recording units, and uploaded to the SDMS. Other data, such aslaboratory data, were manually entered into the SDMS for analysis.For electronic storage and retrieval purposes, each survey measurement is identified by a unique15-digit code. The first seven digits are the survey unit Identification (ID) code (seeSection 2.1.3). The last eight digits are the measurement ID code. The first two digits of themeasurement ID code identify the type of measurement, as shown in the following table, and thelast six digits are the unique measurement location ID.
Measurement Type Codes
Type Code I Type Description01 Static surface beta04 Removable beta smears08 Surface scanning beta
Records of survey data include the surveyor identification, measurement type, measurementlocation, measurement instrumentation used, measurement results, and time and datemeasurement was taken.
2.4.5 QUALITY CONTROL MEASUREMENTS
Quality Control (QC) measurements were performed to identify, assess, and monitormeasurement error and uncertainty attributable to measurement methods or analytical proceduresused in the survey data collection process. Two types of QC measurements were performed on aregular basis: QC checks and repeat measurements. A third type of QC measurement, duplicatesample analysis, was performed but is unrelated to the final survey of the MSSS/EPA/SGBB.Where discrepancies were identified or acceptance criteria were not met, an evaluation wasperformed to determine the cause and identify any necessary follow-up actions.
2.4.5.1 QC Checks
Three direct observations of survey set-up and close-out activities and scan and staticmeasurements were performed. The observations were reviewed with the surveyors and follow-up actions such as on-the-spot correction, surveyor refresher training, changes in work processcontrol, development of good practices, and procedural corrections and improvements weretaken.
2.4.5.2 QC Repeat Measurements
A set of fifteen repeat measurements was collected at each of eight measurement locations. Theselected measurement locations represented a range of residual radioactivity from 4,000 to6,000 dpm/l 00 cm2 . For each data set, the mean value was calculated and compared to the
2-9
TROJA N FINAL SIR 'EY REPOR T- AMSSS/EPA/SGRB
original measurement value. Measurement accuracy was deemed acceptable where the originalmeasurement fell within ±20% of the mean of the repeat measurement data set. The originalmeasurements for four of the eight measurement locations selected did not meet the QCacceptance criterion.
An evaluation was performed which determined that the static measurement locations used forcollecting the QC repeat measurements should not have been selected for use with the LudlumModel 44-9 pancake G-M detector, which was used to collect that particular set of QC repeatmeasurements. As a general rule, repeat measurements are collected at static measurementlocations with residual radioactivity above 5,000 dpm/100 cm2. That value is about three timesbackground for a Ludlum Model 43-68 GFP detector, which is the primary detector used. Thatsame value represents less than two times background for a Ludlum Model 44-9. The QC repeatmeasurement locations all had residual radioactivity levels around 5,000 dpm/l 00 cm2.Measurement locations with results at or near background levels are not used because of therelatively large measurement uncertainty. QC repeat measurements should be collected atmeasurement locations with residual radioactivity at levels greater than two times background, apractice which was inadvertently not applied in the collection of QC repeat measurementsaddressed here.
2.4.6 PROCEDURES
Final survey activities were implemented and controlled using approved plant procedures. A listof those procedures is given in Table 2-2.
2.4.7 TECHNICAL BASIS DOCUMENTS
Calculations and memoranda were prepared to document methods that wvere used, how themethods were derived, underlying assumptions for decisions that were made, the basis fordeviations, and other information that warranted documentation.

3. FINAL SURVEY RESULTS
Final survey scan, static, and supplemental data were collected from the MSSS/EPA/SGBB.Scan measurements were performed over approximately 2,000 m2 and a total of 640 staticmeasurements were collected as final survey data. Table 3-1 summarizes the final survey results.In addition, 640 supplemental removable surface radioactivity measurements (or smears) werecollected, with results all less than 1,000 dpm/100 cm2 . Three data investigations were performedof four locations identified by scan measurements with elevated residual radioactivity. The fourlocations represent a total of approximately 0.1 m2 of surface area with residual radioactivityabove the DCGL. The results of the data investigations are summarized in Table 3-2. A detailedsummary of final survey data for each survey unit is given in the survey unit summary reports inAppendices C, D, and E. Scan measurement data are provided in the Supplement. Measurementresults given in the following sections are for direct surface beta measurements, unless othenvisenoted.
3.1 MAIN STEAM SUPPORT STRUCTURE
The MSSS, shown in Figures 3-1 through 3-3, comprises 10 Class 1 survey units and threeClass 2 survey units. Three investigations were performed of areas identified by scanning withelevated residual radioactivity above the DCGL.

4. DATA ASSESSMENT
Final survey data were reviexved to ensure that they were of a sufficient type, quantity, andquality such that conclusions could be drawn with confidence regarding the radiologicalcondition of the survey unit. Conclusions were drawn and documented in a separate releaserecord prepared for each survey unit. A summary of the release record for each survey unit isgiven in Appendices C, D, and E.
4.1 DATA VERIFICATION AND VALIDATION
Data were reviewed to verify Data Quality Objectives (DQOs) established in the final surveydesign were met. Graphical representations and statistical comparisons of the data were madewhich provided both qualitative and quantitative information about the data. An assessment wvasperformed to verify the data supported the underlying assumptions necessary for the statisticaltests, if applicable.
4.1.1 DATA QUALITY
The final survey data were verified authentic, appropriately documented, and technicallydefensible. Specifically, the following conclusions were made:
1. The instruments used to collect the data were capable of detecting the radiation ofinterest at or below the investigation level.
2. The calibration of the instruments used to collect the data was current andradioactive sources used for calibration were NIST traceable.
3. Instrument response was checked before and, where required, after data collectioneach day.
4. The MDCs and the assumptions used to develop them were appropriate for theinstruments and the survey methods used to collect the data.
5. The survey methods used to collect the data were appropriate for the media andtypes of radiation being measured.
6. Special measurement methods used to collect the data were applied as warrantedby survey conditions.
7. The custody of samples collected for laboratory analysis was tracked from thepoint of collection until final results were obtained.
8. The final survey data set consists of qualified measurement results that arerepresentative of the current facility status and randomly collected as prescribedby the survey design.

4.1.2 GRAPHICAL DATA REVIEW
Survey data were graphed to identify patterns, relationships, or potential anomalies in the datathat might go unnoticed using purely numerical methods. A frequency plot was used to examinethe general shape of the data distribution.
4.1.3 BASIC STATISTICAL COMPARISONS
Statistical quantities (range, median, and standard deviation) were calculated for the final surveydata set for each final survey unit. The calculated quantities were compared to the test valuesshown in the following table.
Basic Statistical Comparisons
Statistical Quantity I Test Value I Failure Response
Range (R) R < 5 a Examine data for outliers
Median (u) I (Q - mean) / a I • 0.5 Examine data for outliers and anomalies
Standard Deviation (a) a < 0.2 x DCGL Determine if more measurements are necessary
Where the statistical quantity failed the comparison, the data set and/or survey designassumptions were examined. The following table summarizes the statistical quantity failures.

4.1.3.1 Range Test
Where the range was greater than 5 standard deviations, the data were examined for outliers.Outliers usually represented true extreme values of a distribution, such as areas of elevatedresidual radioactivity, and indicated more variability in the population than was expected. Therewere two range test failures (S18044A and S18045C); however, no data were discarded. The
4-2
TROJ4I FIN4L S(URV'EY REPORT- AISS<SEPA/S.GRR
failures were generally caused by a very tight distribution with a single outlier with elevatedresults compared to the rest of the data set.
4.1.3.2 Median Test
Failure of the median test indicates large differences between the mean and the median and is anindication of the skewness in the data, warranting an examination of the data for outliers oranomalies. There was a single median test failure (SI8045B); however, no data w ere discarded.The failure was caused by a right-skewed data set.
4.1.3.3 Standard Deviation Test
Where the value of the calculated standard deviation was larger than that estimated in the surveydesign (the initial design value was 0.2 x DCGL), an insufficient number of measurements mayhave been taken and additional measurements may have been necessary. There were no failuresof the standard deviation test.
As an additional measure of assurance, a retrospective power analysis was performed to verifythe power of the Sign test would have been sufficient based on a minimum of 30 measurementscollected and an actual standard deviation larger than that estimated in the survey design. Thelargest standard deviation from actual survey data collected was used (survey unit SI 8044D)along with survey design values contained in the LTP, Appendix 4-1, to construct the poweranalysis. The results, shown in the table below, indicate that fewer than 15 measurements persurvey unit would have provided a sample population of sufficient size to assure statisticalconfidence in the conclusions drawn from the survey data. Therefore, the number ofmeasurements collected was in all cases adequate.

4.2 SATISFACTION OF THE SITE RELEASE CRITERIA
Four conditions were established that, when met, satisfy the site release criteria (seeSection 1.3.1). These conditions were applied to each survey unit as shown in Table 4-1.
4-3
TROJAN FINA 1. St JR VEY REPOR T - A1ISS9/FP ISG RR
4.2.1 CONDITION #1- MEAN TEST
Condition #1 requires that the average residual radioactivity above background be less than orequal to the DCGL. To determine if Condition #1 was met, the mean of the final survey unitdata set for each survey unit was compared to the DCGL. In all cases, the average residualradioactivity was less than 0.2 x DCGL. Therefore, each survey unit satisfies Condition #1.
4.2.2 CONDITION #2- ELEVATED MEASUREMENT COMPARISON
Condition #2 requires that individual measurements, representing small areas of residualradioactivity that exceed the DCGL, do not exceed the elevated measurement comparison (EMC)DCGL. To determine if Condition #2 was met, the individual measurement in the single surveyunit (S18069A) that exceeded the DCGL was compared to the EMC DCGL. The individualmeasurement was less than 0.2 x EMC DCGL. Therefore, the survey unit satisfies Condition #2.
The EMC DCGL was developed using the methodology and the area factors provided in theLTP, Appendix 4-1. The radionuclide-specific area factors given in the LTP could not be useddirectly to develop the EMC DCGL since the gross activity DCGL was derived based on aradionuclide distribution and not on a single radionuclide. Instead, a weighting method wasapplied using the radionuclide distribution and the relative activity fractions used to derive thegross activity DCGL. The radionuclides of interest were those used in the derivation of the grossactivity DCGL. Area factors for use with the gross activity DCGL (except for the gross activityDCGL applied to survey unit SI 8045B) were calculated for areas of elevated residualradioactivity of I mi2 , 4 i 2, and 9 m2 in size. The area factors were 8.5, 2.0, and 1.0,respectively. As applied, areas smaller in size than I m2 were assumed to be I m2 and the I mi2
2value of 8.5 was used. Since there were no areas larger than 1 m , the EMC DCGL was 178,500dpm/100 cm2 (8.5 x DCGL).
4.2.3 CONDITION #3- SIGN TEST
Condition #3 requires that where one or more static measurements exceed the DCGL, theaverage residual radioactivity passes the Sign statistical test. To determine if Condition #3 wasmet, the Sign test would have been applied to the final survey data set of any survey unit withone or more static measurement above the DCGL. In this case, however, there were none.Therefore, each survey unit satisfies Condition #3.
The Sign statistical test was not applied to the final survey data set of any survey unit since nonehad one or more static measurements that exceeded the DCGL. The data provided statisticallysignificant evidence that the level of residual radioactivity in the survey unit does not exceed thesite release dose criterion. The results of the statistical test are the basis for the decision that thesurvey unit is acceptable for unrestricted release can be made with sufficient confidence andwithout further analysis. The Wilcoxon Rank Sum (WRS) statistical test was not used.
It is obvious that if all data measurements in the data set are less than the DCGL, the data set willalways pass the Sign test. Therefore, the Sign test is not performed on such a data set.

TROJAN FN14L St LR VFY REPORT- MSSS/EPA1SGRR
4.2.4 CONDITION #4 - ALARA EVALUATION
Condition #4 requires that remediation be performed where it is ALARA to reduce the levels ofresidual radioactivity to below the concentrations necessary to meet the DCGLs. The levels ofresidual radioactivity were considered ALARA once remediation actions, considered to be costeffective, were taken. To determine if Condition #4 was met, an ALARA evaluation wasperformed for every Class I or Class 2 survey unit. In all cases, the ALARA evaluation verifiedthat remediation was performed where it was ALARA to do so. Therefore, each survey unitsatisfies Condition #4.
The ALARA evaluation ensured that: (I) residual radioactivity had been reduced to levels thatare as low as reasonably achievable, and (2) efforts to remove residual radioactivity werecommensurate with the level of risk the residual radioactivity poses. The ALARA evaluationexamined various remediation actions to determine which actions, if any, have a net benefit infurther reducing the levels of residual radioactivity. The evaluation compared residualradioactivity levels to calculated remediation levels (see Appendix A) for possible remediationactions. The remediation action was taken where the level of residual radioactivity exceeded theremediation level. Conversely, if the concentration was less than the remediation level, the levelof residual radioactivity was documented as ALARA and the remediation action was notperformed. By their classification, Class 3 survey units are considered ALARA and noevaluation is performed.

5. FINAL SURVEY CONCLUSION
The final survey of the MSSS/EPA/SGBB was performed in accordance with the LTP and itsimplementing procedures. Final survey data of adequate quantity and quality were collectedfrom each of the 20 survey units. The survey data for each survey unit showed:
1. The average residual radioactivity, which included the background distribution,was less than the DCGL.
2. Individual measurements, representing small areas of residual radioactivity thatexceeded the DCGL, did not exceed the EMC DCGL.
3. Since no individual measurements exceeded the DCGL, the average residualradioactivity passed the Sign statistical test.
4. Remediation was performed where it was ALARA to reduce the levels of residualradioactivity to below the concentrations necessary to meet the DCGLs.
These conditions satisfy the site release criteria established in the LTP and the radiologicalcriteria for unrestricted use given in 10 CFR 20.1402 (see Section 1.3). Therefore, it isconcluded that the MSSS/EPA/SGBB are suitable for release to unrestricted use.

APPENDIX A
SURVEY PREPARATION ACTIVITIES
This appendix provides a general description of decommissioning activities in the nature of anhistorical assessment that was used to determine the final survey classification of each of theareas within the MSSS/EPA/SGBB. Detailed decommissioning information as well as a briefradiological history is found in the LTP, Section 3.
The MSSS/EPA/SGBB were prepared for final survey by a series of decommissioning activities,including radiological characterization, dismantlement or demolition, remediation, and turnoverto final survey. Radiological characterization data were gathered and analyzed. The resultsguided decisions regarding the need for, extent of, and most effective means of remediation.Highly contaminated structures, equipment, and components were dismantled or demolished andremoved for disposal. Remaining structure and equipment surfaces were remediated, as needed,and then systematically turned over for final survey. An assessment of the operation andradiological history established the initial classification of areas within the MSSS/EPA/SGBB.
RADIOLOGICAL CHARACTERIZATION
Radiological characterization of the MSSSIEPA/SGBB was completed in two phases. The initialradiological characterization was performed as Phase I. It is documented in the "Trojan NuclearPlant Radiological Site Characterization Report," Revision 0.1, dated February 8, 1995. Phase HIinvolved routine radiological surveys, referred to as operational surveys. These surveys wereused to support dismantlement and remediation activities. Areas that were not, or could not be,surveyed during Phase I were surveyed during Phase II. Based on the surveys gathered as part ofPhase II characterization, the predominant beta-gamma emitters on structure surfaces affected byprimary system to secondary system leakage were found to be 60Co and '37Cs.
DISMANTLEMENT AND DEMOLITION ACTIVITIES
Most of the components and equipment in the MSSS/EPA/SGBB were removed and disposed ofConcrete walls were removed or decontaminated. Plate steel, structural steel, grating, ladders,and platforms were decontaminated in place or were removed by unbolting or cutting, anddisposed of.
REMEDIATION ACTIVITIES
Remaining structural and equipment surfaces were remediated using a variety of techniquesranging from wiping to surface material removal. Removable surface radioactivity wasremediated via simple means such as wiping down an area and vacuuming to collect dirt andloose radioactivity from recesses and comers. These were considered good practices and weretypically applied. Grinding or abrasive blasting were used to remove fixed radioactivity fromsteel and surfaces other than concrete. Concrete surfaces were remediated by scabbling.
A-1
TROIYA FINA!t SURVFYREPORT- MAIS/EPAI/NSRR
Remediation levels were established for various types of remediation actions such as scrubbing,grinding, abrasive blasting, and scabbling. Remediation levels were developed using anunbiased analysis of remediation actions that could both avert future dose (a benefit to society)and cost money (a potential detriment to society). They are based on the methodology andassumptions given in the LTP, Section 2.4.2. Where the level of residual radioactivity exceededthe remediation level, the remediation action was taken. Conversely, if the concentration wasless than the remediation level, the level of residual radioactivity was considered ALARA andthe remediation action was not performed.
The remediation levels applied to the MSSS/EPA/SGBB are given below. The exception to this,which is addressed in Appendix B, are the remediation levels applied to survey unit SI 8045B.
Remediation Levels
Remediation Action LevelAction (dpm/100 cm2)
Hand scrubbing 25,000Grinding 30,000Abrasive blasting 65,000Scabbling 78,000
The MSSS/EPA/SGBB were some of the first areas on the plant site to undergo remediation.Early remediation activities preceeded the LTP by several years and were performed under theassumption that, for ALARA purposes, detectable levels of radioactivity had to be removed. Asa result, areas with low levels of detectable radioactivity were remediated. Remediation of theseareas would not have been required by the remediation levels, shown above, that were laterestablished.
TURNOVER
A systematic approach was established for the turnover of the MSSS/EPA/SGBB from theDecommissioning organization to the Final Survey organization. Dismantlement andremediation activities were completed in areas that could be isolated or controlled in such amanner as to minimize the potential for the reintroduction of contamination from ongoingdecommissioning activities in adjacent or nearby areas. These work areas were then prepared forfinal survey data collection. The MSSS/EPA/SGBB were divided into four work areas, listed inthe following table, each of which was turned over separately.

Prior to turnover, a walkdown of the work area was performed when the final configuration wasknown, usually near or after the completion of dismantlement and remediation activities. Thephysical state of the area and the scope of work necessary to prepare it for final survey wereassessed during the walkdown. Requirements for access, isolation, and control were alsoaddressed during the walkdown. Support activities necessary to conduct the final survey, such asscaffolding, interference removal, and electrical tag-outs, were identified. Safety concerns suchas access to confined spaces, high walls, and ceilings were also identified.
Tools, equipment, and materials not needed for final survey data collection were removed.Housekeeping and clean-up activities were completed. Scaffolding and other temporaryequipment needed for final survey data collection were put in place. Administrative and physicalcontrols were instituted to minimize the possibility of introducing radioactive material fromongoing decommissioning activities in adjacent or nearby areas. These measures includedpersonnel training, installation of barriers to control access to the area, installation of postingswith access/egress requirements, and removing access to the area.
HISTORICAL ASSESSMENT AND INITIAL CLASSIFICATION
Based on an assessment of relevant historical information, an initial classification was assignedto the structural surfaces and equipment remaining following the completion of dismantlement,demolition, and remediation activities.
Information used in the assessment included the operational and radiological history of the area,the remediation activities performed in the area, and the radiological characterization datacollected during decommissioning prior to turnover. Measurement results given in the followingsections are for direct surface beta measurements, unless otherwise noted.
MAIN STEAM SUPPORT STRUCTURE
The MSSS was designated a Class I area, with the exception of the some vertical surfaces abovethe 69' and 79' elevations, including the safety relief valve area, which were designated Class 2areas. Operational survey measurement results for the Class 1 areas generally indicated less than50,000 dpm/1u00cm2; however, small areas with levels of up to 150,000 dpm/l00 cm 2 weredetected. For Class 2 areas, operational survey measurement results were less than10,000 dpm/1 00 cm2. Smear results for Class I and Class 2 areas indicated removable surfaceradioactivity up to 1,000 dpm/100 cm2.
ELECTRICAL PENETRATION AREA
The EPA was designated a Class 2 area, with the exception of a lower wall and floor area, whichwas designated Class 1. Adjacent outside areas were designated Class 3 areas. Operationalsurvey measurement results for the Class I area generally indicated levels of residualradioactivity less than 10,000 dpm/100 cm2, with small areas up to 150,000 dpm/100 cm2.Operational survey measurement results for the Class 2 area were less than 18,000 dpm/100 cm2.For the Class 3 area, results were less than 5,000 dpm/1 00 cm2. Smear results for all EPA areasindicated removable surface radioactivity of no more than 2,000 dpm/100 cm2.

SPECIAL HANDLING OF SURVEY UNIT S18045B
Survey unit S18045B consists of concrete floor and lower wall surfaces in the EPA on Elev. 45'that were heavily contaminated, largely due to leakage from the reactor coolant sampling system.Since the source of contamination was direct leakage from the primary system, it was judgedappropriate to apply the Containment gross activity DCGL of 22,000 dpm/I 00 cm2.Remediation levels and area factors based on the Containment gross activity DCGL were alsoapplied to survey unit S18045B. The gross activity DCGL of 21,000 dpm/100 cm2, developedfor areas affected by primary to secondary system leakage, was applied to the balance of theMSSS/EPA/SGBB.
CONTAINMENT GROSS ACTIVITY DCGL
Samples were collected from representative surfaces in the Containment prior to surfaceremediation and were used to establish the radionuclide distribution of surface residualradioactivity. The samples were sent to an offsite laboratory for analysis and the laboratoryresults were used to calculate a gross activity DCGL value for each sample. Severalradionuclides of interest were detected in each of the samples. The predominant beta-gammaemitters were found to be 60Co and 1"7Cs. Alpha emitters were either not detected by sampleanalysis or were detected at activity concentrations that are insignificant in terms of dosecontribution. The radionuclide detected with the highest activity concentration was 137Cs, whichaccounted for between 81 and 98% of the total activity of each sample. For purposes ofcalculating the DCGL, radionuclides of interest that were not detected were assumed present attheir MDC. They were included in the DCGL calculation where their MDC exceeded 10% oftheir respective screening DCGLs. There was some variability in relative radionuclide fractionswhen one sample was compared to another. Therefore, the most conservative calculated value,22,000 dpm/100 cm2, was selected as the gross activity DCGL. The radionuclide distributionassumed for this DCGL is shown below.

REMEDIATION LEVELS
Remediation levels, given below, were developed based on the Containment gross activity forremediation methods applied to the surfaces in the Containment. Remediation levels forconcrete scabbling were not developed for Containment surfaces since nearly all of the surfaceswere metal.
Remediation Levels
Remediation Action LevelAction (dpm/100 cm2)
Hand scrubbing 20,000Grinding 20,000Abrasive blasting 76,000Material Removal 200,000
Concrete scabbling, abrasive blasting, and jack hammering were the remediation methodsemployed to remove the heavy surface contamination in survey unit S1 8045B. Based on theoperational surveys of areas within survey unit S I 8045B, the remediation methods that wereperformed were effective.
AREA FACTORS
Area factors for use with the Containment gross activity DCGL were calculated for areas ofelevated residual radioactivity of I m2 , 4 m , and 9 M2 in size. The area factors were 8.0, 1.9,and 1.0, respectively. Since there were no areas of elevated residual radioactivity found insurvey unit S18045B, the area factors were not used.
TECHNICAL BASIS DOCUMENTS
Calculations were prepared to document the derivation of the Containment gross activity DCGL,and the remediation levels and area factors for use with that DCGL.

, 26,9600.022190.01178,500
Action Taken: Accepted the elevated measurement value, and applied DCGLc. ...
Basis for Action Taken: A single small area of elevated activity was identified by scan survey with a Model 44-9pancake GM detector on a pipe flange exiting the containment building wall. An investigation survey with a Model43-68 GFP detector measured 5,345 dpmnl0Ocm2 for this location. Retained the original scan value as aconservative representation of the area, as it is only 15% of the DCGLC,,,. The original measurement value is alsoALARA, since it is less than the remediation action level for removal.

The GM has relatively low detection I1 6,499 6,000efficiency with small active area resulting in Total:values 1.5 to 2.5 times greater than the GFPD. All data are valid & accepted.

TROJAN FINAL SURVEYREPORT- SUPPLEMENT TO MSSS/EPA/SGBB
INTRODUCTION
This document is a supplement to the Trojan Final Survey Report - Main Steam SupportStructure (MSSS), Electrical Penetration Area (EPA), and Steam Generator Blowdown Building(SGBB). This supplement contains the scan measurement data values and the survey maps thatdocument the locations in each survey unit where scan measurements were performed. Scanmeasurements were typically performed over areas of 1 m2 in size. For each area scanned, thepeak integrated count rate value experienced by the detector over the scan interval was captured.Once the area was scanned, the captured or "latched" value was electronically entered into thedata logger memory. The data were downloaded and electronically converted to recording units.A three-digit number on the survey map identifies each scanned area and corresponds to the lastthree digits of the unique 15-digit code that identifies each survey measurement.
