Vallecitos Boiling Water Reactor (Deactivated)
Annual Report No. 37 General Electric Company has maintained the Vallecitos Boiling Water Reactor (VBWR) in a deactivated status under the authority of Amendment No. 19 to License DPR-1, Docket 50-18.
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 5.d.2 of the license.
1.0
SUMMARY
The facility remains in essentially the same condition described in Annual Report No. 36. Entry into the containment building was made for routine radiation surveys and a general examination of conditions throughout the building. The water level within the reactor vessel was monitored and remained essentially constant throughout the report period.
Radiation levels remain essentially unchanged.
2.0 STATUS OF FACILITY In accordance with written procedures, the Facility Manager controls access to the containment building and general systems. The facility continues to be in deactivated status.
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 period.

VBWR Annual Report No. 37 5.0 ORGANIZATION The management and operations organization for the VBWR is described in Technical Specification 6.1 (Figure 1) of License DPR-1. Although the organizational structure remains the same, the Level 1 manager has changed due to the retirement of G.L. Stimmell. The new Level 1 manager is L.M. Quintana.
6.0 CONCLUSION
The General Electric Company concludes that the deactivated VBWR 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.
