EXECUTIVE SUMMARY

During the report period January 1,1993 to December 31, 1993, various activities were

conducted at the SNEC facility to funher the decontamination and decommissioning efforts at

the site while assuring continued protection of the health and safety of the public and SNEC

staff.

A total of 41 individuals made 92 entries into the Containment Vessel (CV) on 15 separate

occasions. These entries were made for Technical Specification quarterly surveys, routine

housekeeping and related work, decommissioning planning, and NRC and GPUN management

tours.

All of the required Technical Specification quanerly radiation surveys were successfully

conducted. In addition, the supplemental environmental monitoring program maintained by GPU

Nuclear at the site continued during 1993. Results of these monitoring programs and surveys

indicate that there has been no appreciable change in the radiological or environmental conditions

at the facility when compamd to previous years. The facility currently poses no increased risk

to the health and safety of the public.

ANNUAL REPORT IN COMPLIANCE WITH PARAGRAPII B.5.bOF THE SNEC TECIINICAL SPECIFICATIONS

JANUARY 1,1993 - DECEMBER 31,1993

IntIfMhtflion

This repon is prepared in compliance with Section B.5.b of the Saxton Nuclear ExperimentalCorpomtion (SNEC) Technical Specifications. The mporting period covers January 1,1993 toDecember 31, 1993. Each section presented corresponds to the appmpriate mponingrequirement of the Technical Specifications.

A. In[gnpation Relating to Changes in those_ Staff Positions that are Designated as being_

Resoonsible for the Deactivated Facility. - (Section B.5.b(1))

Them were no changes in staff positions responsible for the deactivated facility during1993.

B. Summary of Entries into the Containment Vessel (CV) and Reason for Each Entry. -

(Section B.5.b(2))

A list of 1993 entries into the SNEC Containment Vessel and mason for each ispresented below.

C. Summary of Maintenance and Design Chances Made to the Deactivated Facility. -(Section B.5.b(3))

There were no maintenance and design changes instituted during 1993.

D. Results of Radioactivity Ixvels and of Water Samole Analyses. - (Section B.5.b(4)).

Analysis results of water samples from the CV sump and CV pipe tunnel are presentedin Tables I and II. Sample results from the CV sump contain the highest activity. Thisis consistent with previous data. The water in the CV sump is completely contained andnot in contact with the environment, therefore, there is no threat to the public health andsafety. CV sump water originates from condensation that forms on the inside of the CVwalls which drains downward into the sump. CV sump capacity is approximately 325gallons. Water levels are measured quarterly and have shown slight increases. The sumpcontained approximately 120 gallons of water on 12/31/93.

Table III presents the highest contact dose rates on the CV Operating Deck and thehighest waist level dose rates taken around the CV and Penelec perimeter fences duringthe quarterly surveys. Count rate information obtained from surveys of the CV HighEfficiency Filter is pmsented in Table IV.

Dose rates at the 20 permanent survey points in the CV were less than 0.2 to 0.4 mr/hr.The data are presented in Table V. Smear surveys from the same 20 permanently

2marked points ranged from less than minimum detectable activity to 2900 dpm/100cm(Table VI). The data from these surveys are generally consistent with past results anddo not display any adverse trends.

1

In 1992, after demolition of the outbuilding structures was completed, 8 piezometers !

were installed around the Site to provide groundwater movement information. Several l

additional monitoring wells will be installed near the CV in early 1994 based on thepiezometric data obtained. Four of these piezometers were sampled and analyzed bygamma spectroscopy. These results are reported in Table VII.

|

E. Review of the Performance of Security and Surveillance Measures. - Section B.5.b(5))

During 1993 there were no break-ins or no known attempted break-ins at the SNECfacility. No changes were made to in-place security features since demolition of the ,

outbuilding structures was completed in 1992. ||
