ANNUAL REPORT NO. 38 FOR THE YEAR 2005 LICENSE DR-10 DOCKET 50-183 MARCH 2006 ESADA-Vallecitos Experimental Superheat Reactor (Deactivated)

Annual Report No. 38 General Electric Company has maintained the ESADA Vallecitos Experimental Superheat Re,.ctor (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 annual report, a summary of the status of the facility for the period of January 1, 2005 to December 31, 2005 is presented, as required by paragraph 3.E.2. of the license.1.0

SUMMARY

Th: facility remains in essentially the same condition described in Annual Report No. 37. Entry into the containment building was made for routine radiation surveys and a general examination of conditions throughout the building.

In accordance with written procedures, the Facility Ma aager controls access to the containment building.Radiation levels remain essentially unchanged.

2.0 STATUS

OF FACILITY The facility continues to be in deactivated status. The plugs to the reactor vessel and head stoi age shield, the wooden cover over the fuel storage pool, and the locked covers for the per ;onnel and equipment hatchways remain in-place except during maintenance or inspection activities.

3.0 RADIATION

AND CONTAMINATION Complete radiation and contamination surveys of the facility indicate that levels remain low.Results of the surveys are presented in Table 1. The radiation/contamination levels listed are rep:.esentative but not necessarily maximum values.4.0 ACTIVITIES Routine inspections were conducted during this report period. There were no preventive or cornective maintenance activities performed having safety significance during the reporting period.Page 1 of3 EVESR Annual Report No. 38 5.0 ORGANIZATION The management and operations organization for the EVESR is described in Technical Specification IX of License DR-10. The organizational structure remained the same. The Site Maaager was S. A. Bump. C. W. Bassett was the EVESR Facility Manager.

6.0 CONCLUSION

Th: 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.
