SUMMARY
The facility remains in essentially the same condition described in the twenty-eighth annual l report. Entry into the containment building was made for routine radiation surveys and a general check of conditions throughout the building.
)
l Radiation levels remain essentially unchanged. ,
i II. STATUS OF FACILITY Access to the containment building is controlled by the Facility Manager 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.

- EVESR Annual Report No. 29 III. RADIATION AND CONTAMINATION Complete radiation and contamination surveys of the facility indicate that the levels remain low.
Survey results are tabulated in Table 1. The radiation / contamination levels listed are representative but not necessarily maximum values.
IV. .AO ii 3 TIES Routine inspections were conducted during this report period.
V. ORGANIZATION There were no organization changes in 1996.
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.
