Retired Facility Site Representative (RFSR)
D. A. McKown, a certified Health Physicist and BCL Radiological Safety Officer continues as RFSR for tne facility.
Facility Status The retired facility continues to be controlled by the Technical Specifications of the R-4 license.
The use of the facility is under the purview of the Radio-active Materials Subconinittee (RSC-1) of the BCL Radiological Safety Committee and the RFSR. Uses of the facility for purposes involving nominal radiological considerations is reviewed and approved by the RFSR.
Uses of the facility which may involve substantial radiological considerations are reviewed by RSC-1 and approved by the laboratory director.
Security and Surveillance The facility remains within the confines of the protected Nuclear Sciences area.
A staff of Security Inspectors maintain surveillance and area access control 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />s-a-day. Unescorted access to the area is limited to persons on an approved access list. All others are escorted.
Environmental Survey On-site and off-site environmental monitoring is maintained for the Nuclear Sciences area according to DOE and NRC requirements. A report of the off-site accumulated data is compiled and submitted annually. A copy of the report for the calendar year 1981 A ttached for your information, hO b00?oj$8@fy, Pnn

June 15,1982 Retired Facility Surveys Quarterly surveys for removable contamination and exposure rates in the facility were made at selected locations and reported to the site manager. Smears were usually taken at 80 locations and dose rates taken at the 10 highest 2
locations. The data for removable beta activity did not exceed 100 dpm/100 cm and the exposure rates were all 2 mR/hr or less at all unrestricted locations.
The sources which elevated the exposure rate in the G. E. pool area have been removed from the building.
Water Monitor All water from the old hot drain system is collected in a sump with no outlet except a sump pump. The pump is controlled by a float switch and water monitor in series. All water pumped from the sump passes through the monitor chamber.
If the monitor reading exceeds the set point the monitor alarms and disconnects the power to the pump. The monitor response is checked weeky electronically and by an internal source and is calibrated approximately annually at three points on its range with Cesium-137 solutions. No activity has exceeded the 10 CFR 20 limits since the last report.
Facility Uses I.
Drop tests.
The drop tests, conducted in the main pool area, have not been resumed.
II. The research program with the small quantities of I-131 has been discontinued and the equipment used for that operation cleaned up.
III. Current uses of space Basement area 1.
Old pump room, north east basement - sump, pump and water monitor.
2.
North basement - storage of drum packages of Pu bearing waste.
3.
