VBWR Annual Report No. 45 Vallecitos Boiling Water Reactor (Deactivated)
Annual Report No. 45 GE Hitachi Nuclear Energy 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, 2009 to December 31, 2009 is presented, as required by paragraph 5.d.2 of the license.
1.0
SUMMARY
All reactor systems have been removed from the containment except for the reactor vessel.
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 in safe storage condition.
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.
Dismantling operations did not significantly increase the site's airborne radiological effluent release rate. Continuous general air sampling was performed within the VBWR containment during dismantling operations for personnel monitoring and to assess the potential release of radiological effluents to the environment. Using The Comply Computer Code, a conservative estimate of the Effective Dose Equivalent to the public from all on site sources was less than 0.8 mrem/year.
