i I Annual Report in compliance with Paragraph B.S.b of the Technical Specifications B.5.b(1) "Information relating to changes in those staff positions that are designated as being responsible for the deactivated facility."

In 1983, there were no changes in staff positions responsible for maintaining the deactivated SNEC facility.

B.5.b(2) "A summary of entries into the Containment Vessel or Radioactive Waste Disposal Facility and reasons for entry."

.g B.5.b(3) "A summary of maintenance ar.d design changes made to the deactivated facility."

In August 1983, the roof of the Control and Auxiliary Building (C&A) was retarred.

In October 1983, weeds and trees were cut down from the entire site, including the area around the CV and the Filled Drum Storage Bunker.

In October 1983, the CV sump was pumped dry and the water was stored on the CV operating deck. A subsequent inspection of the sump confirmed that it remained dry.

B.5.b(4) "Results of surveys of radioactivity levels and of water sample analyses."

Results of the 1983 Quarterly inspections of the facility are as follows:

a) Analysis results of water samples from the CV sump, RWDF, and CV pipe tunnel are presented in Tables 1, 2, and 3, respectively. The water samples from the CV sump were the only samples to yield radioisotopic concentrations in excess of 10 CFR 20, Table II, Column 2, Units for Unrestricted Areas.

b) Radiation levels at the exclusion area fence were <.05 mR/hr measured every quarter.

c) Radiation levels at the CV HEPA filter were <0.05 mR/hr measured every quarter.

d) Radiation levels'at the 20 permanently marked survey points in the CV ranged from <0.05 mR/hr to 0.15 m'R/hr. The results are presented in Table 4. Smear surveys from the same 20 points yielded a range of

<1,000 to 5,000 dpm. The survey results are presented in Table 5.

e) Radiation levels in the CV above elevation 812' ranged from <.05 to 0.5 mR/hr.

B.5.b(5) "A summary of the performance of security and surveillance measures."

There were no observed attempted break-ins, vandalism, or other security breaches at the facility during 1983.
