i In. March, 1982, the drain pipe in the Containment Vessel was cut and capped in an attempt to prevent-the flow of water to the Containment Vessel

, sump.

In October, 1982, security bars were installed on selected windows and doors

, of the Control and Auxiliary '(C&A) Building, and the Radioactive Waste Dis-

! posal Facility (RWDF) Building.

4. "Results of surveys of radioactivity levels and of water sample analyses."

Results of the 1982 Quarterly Inspections of the facility are as follows:

?

, 1) Radiation levels at the exclusion area fence ranged from<0.01 mR/hr to

<0.06 mR/hr.

, 2) Radiation levels at the Containment Vessel's breather pipe filter ranged from<0.05 mR/hr to<0.02 mR/hr.

3) Radiation levels at the 20 permanently marked survey points in the

. Containment Vessel ranged from<0.02 mR/hr. to<0.12 mR/hr. Smear surveys from the same 20 points yielded a range of<500 to 9,000 dpm.

I

4) Radiation levels in the Containment Vessel above elevation 812' ranged from .05 to 0.1 mR/hr.

See attachments: Table 1 - SNEC Pipe Tunnel Water 1982 Table 2 - SNEC RWDF Building Water 1982 Inspection of the Containment Vessel lower levels indicates the vessel is i dry and free of water.

The water in the Containment Vessel sump, reported by SNEC letter- to NRC Office of Inspection and Enforcement dated April 27, 1982, was removed j from the sump, packaged with Vermiculite in two 55 gallon drums, and stored in the Containment Vessel.

l- 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 1982.
