SUMMARY
Component removal activities began in 2008 above the 549 foot level. Tech Spec changes issues in Amendment 7 December 1, 2008 authorize the removal of systems beside the reactor vessel and bio-shield below the 549 level. Component removal continued in 2009 will continue in 2010. Entry into the containment building was made for routine radiation surveys and a general examination of conditions throughout the building. In accordance with written procedures, the Facility Manager controls access to the containment building.
Radiation levels remain essentially unchanged. Contamination levels are up slightly, reflecting the ongoing equipment-removal activities.
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 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. Component removal and downsizing was continued.
4.234 mCi of material in 2354 ft 3 were removed and disposed in at the facility in Clive, Page 2 of 3
