ESADA VALLECITOS EXPERIENTAL SUPERHEAT REACTOR ANNUAL REPORT NO. 12 (Deactivated)
General Electric Company has maintained the ESADA Vallecitos Experimental Super-heat Reactor (EVESR) in a decctivated status under the authority of Amendment No. 3 to License DR-10, Docket 50-183, issued June 11, 1976. In this twelfth annual report, a summa, y is presented to the status of the facility for the period from January 1,1979 to December 31, 1979 as required by Paragraph 3.E.2 of the license.
I.
SUMMARY
The facility remains in essentially the same condition described in the eleventh annual report. Entry into the containment building was made for routine radia-tion surveys and a general check of conditions throughout the building.
Ra dia-tion 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 Complete radiation and contamination surveys of the facility indicate that the levels remain low as reported previously. Survey results are tabulated in Table 1.
IV.
ACTIVITIES Come instruments were removed for use elsewhere on the VNC site and routine inspections were conducted during this report' period.
V.
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. These procedures will be continued to maintain this high level of protection.
