't Vallecitos Boiling Water Reactor Annual Report No. 21 (Deactivated)
The status of the Vallecitos Boiling Water Reactor (VBWR) during the calendar year of 1985 is described in this twenty-first report of the deactivated facility in conformance with License DPR-1, Docket 50-18, Amendment 19, Paragraph 5.d.2.
I.
SUMMARY
The facility remained essentially in a static condition as described in Annual Report No. 20. Entry into the containment building was made for routine radiation surveys and for a check of general conditions throughout the building to verify the unchanged condition of the facility. The reactor vessel water level was monitored and remained essentially constant.
II.
STATUS OF THE FACILITY A.
Containment Building No changes were made during the report period.
B.
General Systems No changes were made during the report period.'
III.
PERIODIC INSPECTIONS Inspections of the facility were continued on a routine basis. The annual air samples and radiation and contamination surveys of the contairment building
.are given in Table 1 of this-report.
IV.
RADIATION AND CONTAMINATION Radiation and contamination surveys of the facility indicate the levels in all cases were well below the limits for any safety concern.
t
VBWR Annual Report No. 21 V.
ORGANIZATION There were no changes in organization.
VI.
CONCUJSION In our coinion, the deactivated Vallecitos Boiling Water Reactor continues to
~
be maintained in a safe condition, commensurate with its shutdown status. The-methods of inspection and control of safety-related items ensure maximum protection for the public'and the General Electric Company.
