4 ESADA-VALLECITOS EXPERIMENTAL SUPERHEAT REACTOR (DEACTIVATED) l l ANNUAL REPORT NO. 21 General Electric Company has maintained the ESADA Vallecitos Experimental Superheat Reactor (EVESR) in a deactivated status under the authority of Amendment No. 3 to License DR-10, Docket 50-183, issued June 11, 1976. In this twenty-first annual report, a summary is presented as to the status of the facility for the period from January 1, 1988, to December 31, 1988, as required by Paragraph 3 E.2. of the license.
I.
SUMMARY
The facility remains in essentially the same condition described in the twentieth annual report. Entry into the containment building was made for routine radiation surveys and a general check of conditions throughout the building. Radiation levels remain essentially unchanged.
II. STATUS OF THE FACILITY Access to the containment building is controlled by the facility supervisor according to written procedures. The reactor vessel and head storage shield plugs, the wooden cover over the fuel storage pool, and the locked covers for the personnel and equipment hatchways remain in place.
III. RADIATION AND CONTAMINATION i
Complete radiation and contamination surveys of the facility indicate that the levels remain low. On January 14, 1988, Amendment No. 4 to License DR-10 was issued which changed the frequency of the general survey from twice annually to annually. Survey results are tabulated in Table 1. The radiation / contamination levels listed are representative but not necessarily maximum values.
IV. ACTIVITIES Routine inspections were conducted during this report period.

VI. CONCLUSION The General Electric Company concludes that the deactivated ESADA Vallecitos Experimental Superheat Reactor is being maintained in a safe shutdown condition. The inspections, access control, and administratively controlled activities ensure maximum protection for the public health and safety. The procedures will be continued to maintain this high level of protection.
