SUMMARY

f During the report period January 1,1989 to December 31, 1989, various activities were conducted at the SNEC facility to further the decontamination and decommissioning efforts at the site while assuring continued protection of the health and safety of-the public and SNEC staff. Final release surveys of the Control and Auxiliary (CaA) Building and Radioactive Waste Disposal Facility (RWDF) were commenced in October 1988 and were completed at the end of June 1989. A total of 23 entries were made into the Containment Vessel (CV). These entries were made for Technical Specification quarterly surveys, routine housekeeping and related work, and management tours. All of the required Technical Specification quarterly radiation surveys were. [ successfully conducted at the facility. In addition, the supplemental environmental monitoring program maintained by GPU Nuclear at the site continued during 1989. Results of these monitoring programs and surveys indicate that there has been no appreciable change in the radiological or i environmental conditions at the facility when compared to previous years. The facility currently poses no threat to the health and safety of the public. l l l ) 9

j ANNUAL REFORT IN COMPLIANCE WITH PARAGRAPH B.S.b I c' THE SNEC TECHNICAL-SPECIFICATIONS D Mnuary 1,1989 - December 31, 1989 l Introduction j t This. report is prepared in compliance with Sectior. B.5.b of the Saxton Nuclear Experimental Corporation (SNEC) Technical Speci'ications. The reporting period covers January 1,1989 to December 31, 1989. Each section presented corresponds to the appropriate reporting requirement of the Technical Specifications. i' A. Infonnation Relating to Changes-in those Staff Positions that are. Designated as being Responsible for the Deactivated Facility. , i - (Section B.5.b(l;') The following changes occurred in staff positions responsible for the i deactivated f acility during 1989. { NAME NATURE OF CHANGE EFFECTIVE DATE .

Summary of Entries into the Containment Vessel (CV) or Radioactive Waste D_i sposal Faci li ty (R.W.D.F. ) and Reason for Each Entry. - (Section B.5.b(2)) - During the first half of 1989, maintenance and decontamination activities necessitated entries into the RWDF nearly every' day by several indivi dual s. There were 857 entries into the RWDF during the time frame 1 of January 1,1989 to December 31,_1989. Daily. sign-in and sign-out logs are on file and available fer inspection. A list of. entries into the SNEC Containment Vessel and reason for each is presented below. 1, 1/9/89 Securi ty 3 2. 1/10/89 Housekeeping and related work 3. 1 /17 /89 Housekeeping and related work 4. 1/18/89 Housekeeping and related work 5. 1/19/89 Housekeeping and related work 6. 1/25/89 Housekeeping and related work -l 7. 1/29/89 Housekeeping and related work ] 8. 1/30/89 Housekeeping and related work 9. 1/31/89 Housekeeping and related work i 10. 2/1/89 Housekeeping and related work 11. 2/2/89 Housekeeping and related work l 12. 2/3/89 Housekeeping and related work l 13, 2/7/89 Housekeeping and related work l 14. 3/16/89 First Quarter Inspection 15. 3/ 28 /8 9 SNEC B00 Tour 16, 4/19/89 GPUN Audit Team Tour 17. 5/4/89 Housekeeping and related work 18.

Summary of Maintenance and Design Changes Made to the Deactivated Facility. - (section B.b.bl3) } During ic39, there were no major maintenance or design changes made at SNEC. Some minor changes-related to final radiological surveys in the RWDF and coa Buildings were made (i.e., surface decontamination). D. Results of Radioactivity Levels and of Water Sample Analyses. g - (Section B.5.b(4)) Analysis results of water samples-from the CV, RWDF. Sump and CV pipe tunnel are presented in Tables I,11,. III. respectively. Samples from the CV sump contain the highest activity. This'is consistent with previws years data. The water in the CV sump is completely contained and not is contact with the environment, therefore.there is no threat to-the public healt.h and safety. CV sump water originates from small amounts of condensation that form on the inside of the CV walls and drain downward into the sump. CV Sump capacity is approximately~ 325 gallons. It contains approximately 125 gallons of water. Water levels are ? measured quarterly and remain essentially unchanged. Table IV-presents the highest contact dose rates on the CV Operating Deck and the highest walst level dose rates taken artund the CV and Penelec { perimeter fences during the quarterly surveys. Dose rate information obtained from surveys of the CV High Efficiency Filter is presented in Table V. Dose rates at.the 20 pennanent survey points in the CV ranged from less than 0.2 mr/hr to 0.2 mr/hr. The data are presented in Table VI. Smear surveys from the same 20 pennanently marked pgints ranged from less than minimum detectable activity to 4510 dpm/100cm (Table VII). All survey 99 99 l

t points except 1 and 2 are locateo in a posted contaminated area.- Survey 7_ points 8, 9,12 and 13 are the only points to have smearable contamination which met posting requirements. These four points are located along the walkway to the lower levels of the CV and display the movement, by survey crews, of loose contamination from the lower levels to_ a radiological control point. The data from these surveys are l generally const stent with past results and do not. display _any adverse.

trends, Table Vlli contains. results from a composite sampler for groundwater t

being discharged from the RWDF and Pipe Tunnel.. E. Re_ view ^of the Performance of Security and Surve111anco Measures. - ( Section B. 5.b( b )) During 1989 there was one (1) break-in and' one (1) attempted break-in at the SNEC facility. They were as follows:- 1. January 1,1989 ' Lock cut' on truck gate, _ fence cut, hasp broken on SNEC office trailer _.- No. items > appeared to be missing. Incident' reported to Liberty-Township' Police. Lock-and hasp replaced and l fence repaired. 2. January 7,1989 Attempted break-in. During 1989 additional security measures were taken. They were as' follows: 1. February 9,1989 Additional ' security al'anns were installed at the SNEC facility. 2. February 13, 1989 SNEC: perimeter area fence south of-the bunker was replaced with new fencing. 3. March 1,1989 Penelec increased:its security by installation l-of utility poles around perimeter of Penelec property. , =
