VBWR Annual Report No. 52 Vallecitos Boiling Water Reactor (Deactivated)

Annual Report No. 52 GE Hitachi Nuclear Energy has maintained the Vallecitos Boiling Water Reactor (VBWRI in a deactivated status under the authority of Amendment No. 21 to license DPR-1, Docket 50-18, issued Oct 22. 2007. In this annual report. a summary of the status of the facility for the period of January 1. 2016 to December 31, 2016 is presented. as required by paragraph S.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 has remained essentially constant throughout the report period.

Radiation and contamination levels remain at acceptable levels. Environmental data is maintained on site and available for review.

2.0 STATUS OF FACIUTV 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 ond contamination surveys of the facility indicate that levels remain low.

Results of the surveys are presented in attachment 1. Air sampling results are presented in attachment 2. The radiation/contamination levels listed ore representative but not necessarily maximum values.

4.0 ACTIVITIES Routine inspections were conducted during this report period. No other significant activities occurred at VBWR.

Technical Specifications. section C. 1.

1.0

SUMMARY

Component removal activities began in 2008 above the 549 foot level. Tech Spec changes issued in Amendment 7 December 1. 2008 authorize the removal of systems beside the reactor vessel and bio-shield below the 549 level. Component removal concluded (current scope) in 2010. Entry into the containment building was mode for routine radiation surveys and o general examination of conditions throughout the building. In accordance with written procedures. the Facility Manager controls access to the containment building.

Radiation and contamination levels remain at acceptable levels. Environmental data is maintained on site and available for review.

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 remain in place.

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 attachment 1. Air sampling results are presented in attachment 2. The radiation/contamination levels listed are representative but not necessarily maximum values.

4.0 ACTIVITIES Routine inspections were conducted during this report period.

The equipment disposal concluded during 2010.

l.OSUMMARV The facility remains in essentially the same condition described in Annual Report No. 54. Entry into the reactor building was made for routine radiation surveys and o general examination of conditions throughout the building. The crone, elevator, and ventilation were serviced and tested in 2011 in anticipation of beginning remediation activities. Such activities hove not begun.

Radiation and contamination levels remain at acceptable levels.

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. There were no changes authorized by the Facility Manager pursuant to 10CFR50.59Iol in 2015.

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 attachment 1. Air sampling results ore presented in attachment 2. The radiation/contamination levels listed ore representative but not necessarily maximum values.

The data below are from sample and dosimeter results accumulated during 2016.

These data are for the entire VNC site and include the effects of operations other than GETR.
