ESADA Vallecitos Experimental Superheat Reactor Annual Report No. 18 (Deactivated)
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 eighteenth annual report, a summary is presented as to the status of the facility for the period from January 1,1985, to December 31, 1985, as required by Paragraph 3.E.2. of the license.
I.
SUMMARY
The facility remains in essentially the same condition described in the seventeenth 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 Complete . radiation and contamination surveys of the' facility indicate that ~the levels remain low. Survey results are tabulated in Table.l.
IV. ACTIVITIES Routine inspections were conducted during this report' period.
V. ORGANIZATION There were no changes in the organization.
E
O EVESR Annual Report No.18 VI. CONCLUSION The General Electric Company concludes that the deactivated ESADA Vallecitos Experimental Superheat Reac cr is being maintained in a safe shutdown condition. The inspections, access control, and administratively controlled activities ensure maximum pro ection for the public health and safety. The procedures will be continueo co maintain this high level of protection.
