'VALLECITOS BOILING WATER REACTOR (DEACTIVATED)
ANNUAL REPORT NO. 22 The status of the Vallecitos Boiling Water Reactor (VBWR) during the calendar year of 1986 is described in this twenty-second 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. 21.
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 vas monitored and remained essentially constant.
II.
STATUS OF Ti1E FACILITY A.
Containment Buildinn No changes were made during the report period.
B.
General Systems No changes were made during the report period.
III.
PERIODIC INSPECTIONS I
Inspections of the facility were continued on a routine basis.
The annual air samples and radiation and contamination surveys of the containment. building are given in Table 1 of this report. The levels shown are representative and are not necessarily maximums.
Surveys in several areas have been discontinued as they were no longer providing useful data this long after deactivation and, thus, continued monitoring is not consistent with ALARA.
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.

ORGANIZATION There were no' changes in organization.
VI.
CONCLUSION The deactivated Vallecitos Boiling Water Reactor continues to be maintained in a safe condition, commensurate with its shut down status. The methods of inspection and control of safety-related items ensure maximum protection for the public and the General Electric Company.
