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