ANNUAL REPORT NO. 34 FOR THE YEAR 2001 LICENSE DR-10 DOCKET 50-183 MARCH 2002

ESADA-Vallecitos Experimental Superheat Reactor (Deactivated)

Annual Report No. 34 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 annual report, a summary of the status of the facility for the period of January 1, 2001 to December 31, 2001 is presented, as required by paragraph 3.E.2. of the license.

1.0

SUMMARY

The facility remains in essentially the same condition described in Annual Report No. 33. Entry into the containment building was made for routine radiation surveys, a general examination of conditions throughout the building, and a maintenance project. In accordance with written procedures, the Facility Manager 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 storage shield, the wooden cover over the fuel storage pool, and the locked covers for the personnel 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 representative but not necessarily maximum values.

4.0 ACTIVITIES Routine inspections were conducted during this report period. There were no preventive or corrective maintenance activities performed having safety significance during the reporting Page 1 of 3

EVESR Annual Report No. 34 period.

5.0 ORGANIZATION The management and operations organization for the EVESR is described in Technical Specification IX of License DR-10. Although the organizational structure remains the same, the General Manager has changed due to the retirement of G.L. Stimmell. The new General Manager is L.M. Quintana.

6.0 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.
