1.0 INTRODUCTION.

The purpose of this sampling effort is to obtain and analyze samples from flush solutions at the PUREX facility to confirm the solutions do not designate as dangerous waste per WAC 173-303. To meet commitments with the regulators, samples must be collected, handled, and analyzed according to SW-846 Protocol. This Sampling and Analysis Plan is written to provide direction for the sampling and analytical activities determined by the data quality objectives (section 3.0) for PUREX canyon and vault vessels. Another sampling and analysis plan will be prepared for vessels not located in the PUREX canyon and vaults.

2.0 FLUSHING DESCRIPTION

Flush solutions will be sampled from PUREX canyon and vault vessels. There are 15 loops (systems) designated for flushing (a total of 72 vessels). Flush solutions will be cascaded from one vessel to the next within each loop. flush loop.

Samples will be collected in a tank at the end of the

For each loop containing a vessel identified in the PUREX Part A, process screening samples will be collected by PUREX Deactivation Engineering and analyzed by the PUREX laboratory during the course of flushing activities. Screening samples will be taken of each flush until laboratory results indicate the waste no longer exhibits dangerous waste characteristics. After screen sampling is complete, sampling will be conducted in accordance with this sampling and analysis plan.

Regulated dangerous waste constituents within the low level mixed waste vary by loop. Flush solutions may contain cadmium, chromium, lead, barium, silver, arsenic, selenium, mercury, nitric acid, or organics. Radioactive components of the mixed waste are attributed to past processing activities at PUREX.

Flushing will support a 1992 RL directive to deactivate the PUREX Plant. A vital part of deactivation is removing dangerous constituents from the PUREX process vessels (i.e. tanks, columns, concentrators, reboilers, towers, and centrifuges) by means of flushing.

3.0 DATA QUALITY OBJECTIVES

The data quality objectives (see WHC-SD-EN-TI-283, REV. 0) of this sampling effort define the sampling and analysis necessary to support the deactivation of the Plutonium-Uranium Extraction (PUREX) facility vessels that are regulated pursuant to Washington Administrative Code 173-303.

Technical discussions between the U.S. Environmental Protection Agency (EPA), the State of Washington Department'of Ecology (Ecology), the Department of Energy, Rich1 and Operations Office (RL) , and Westinghouse Hanford Company (WHC) have concluded that the analytes listed in Table 1 will be evaluated for their presence on a loop-by-loop basis. can be demonstrated through a letter detailing the process knowledge that a contaminant is not present in a loop, laboratory analysis for that constituent will not be performed. The flush solution will be designated as a dangerous waste if concentrations of any analyte in the matrix are greater than the concentrations in Table 1. If the flush solution is designated as a dangerous waste, the system will be re- flushed and sampled until sample results indicate the flush solution no longer contains dangerous waste constituents in regulated concentrations .

When it

To achieve this data quality objective, it is crucial that the analytical effort properly address the required analytical quantification limits. Targeted analytical quantification limits for the PUREX flush analytes are listed in Table 1. Quality Assurance/Qual i ty Control procedures for performing analyses on waste samples will be equivalent to methods outlined in SW-846, "Test Methods for Evaluating Solid Waste". Handling and preparation of samples will use SW-846 as guidance for methods and protocols when preparing and executing waste sampling. Table 2 summarizes the methods and handling protocol. of this document. Any other deviations must be done in accordance with the Hanford Analytical Services Quality Assurance Plan (DOE/RL-94-55) and the Selection of Analytical Methods for Mixed Waste Analysis at the Hanford Site (DOE/RL-94-97) and reported to Ecology.

Deviations from this guidance are identified in section 5.5.1

5.5.1 Devi a t i ons From SW-846 The SW-846 guidelines for sampling will be followed except for the protocols that cannot be met due to high radiation dose rates or sampling equipment limitations while collecting samples in the PUREX facility.

The deviations from these protocols are discussed below:

SamDfe Dilutions: exceeding safe 1 eve1 s (see Tab1 e 11 , operating procedure PO-080-385), sample volumes may be limited to a maximum of 5 ml. limits, dilution o f the sample may be required in order to obtain sufficient sample volume for the analysis and to reduce the dose rates to an acceptable level for handling. Several analytes may only be present in trace quantities. Due to this safety consideration, it is possible for their concentration to drop below the detectable limit after dilution. Quantification limits in Table 1 may not be met if sample dilution occurs. However, it is unlikely that the dose rate of flush solutions sampled will require dilution.

For samples with radiation dose rates

F o r those samples exceeding the radiation dose

Volatile Orsanic Analysis (VOA): The VOA requires for the sample vial to have zero headspace: This requirement may not be achieved while sampling the flush solution. Due to limitations of the existing sampling equipment and As Low As Reasonable Acceptable (ALARA) concerns, sufficient sample to achieve zero headspace may not be obtainable. every possible effort will be taken to achieve zero headspace.

However,

Other deviations from SW-846 related to the sample collecting, hand1 ing, and analysis must be reported to Ecology. Analysis will be performed in accordance to Hanford Analytical Services Quality Assurance P1 an (HASQAP) DOE/RL-94-55 and Selection of Analytical Methods for Mixed Waste Analysis at the Hanford Site, Section 3.0 (DOE/RL-94-97).

6.0 QA/QC REQUIREMENTS

6.1 FIELD L06BOOK All sampling activities associated with the PUREX canyon vessel flushing will be documented in field logbooks maintained by SML and in the PUREX facility. Field logbooks will be filled out by SML in accordance with E11 1.5 "Field Logbooks" or SML equivalent procedure, to ensure that a particular sampling situation can be reconstructed at some future time. Field logbooks which will be maintained at the PUREX facility will be f i 1 1 ed out in accordance with pl ant operating procedure PO-080-385.

6.2 QUALITY ASSURANCE/QUALITY CONTROL (QA/QC)

6.2.1 Samples A radiological screening sample and two sets o f RCRA samples will be collected by SML per sampling event. Per Ecology's request, WHC will provide Ecology with one set of RCRA samples to be shipped to the laboratory of their choice. This laboratory's acceptance criteria will depend on its current capability to accept RAD samples without violating its dose rate 1 imits permitted under their 1 icense.

Field blanks will be prepared for the analytes listed in Table 1 by SML. Clean containers will be filled with Reverse Osmosis/De-Ionized (RO/DI) type I1 water at the sampling site for each set of RCRA samples. The blanks are sealed and accompany the samples to the laboratory for analysis. All blanks will be assigned HEIS numbers.

6.2.2 Quality Control The field blank is a sample of analyte-free media prepared at the sampling site and accompanies the sample to the laboratory. A field blank is used to document contamination attributable to field handling procedures and the sampling environment. This type of blank is useful in documenting contamination of volatile organics samples. All blanks will be assigned HEIS numbers.

A matrix spike is an aliquot of sample spiked with a known concentration of target analyte(s). The spiking occurs prior to sample preparation and analysis. in a given sample matrix.

A matrix spike duplicate is an intralaboratory split samples spiked with identical concentrations of target analyte(s). The spiking occurs prior to sample preparation and analysis. precision and bias of a method in a given sample matrix.
