Attachment NOC-AE-1 1002770 Page 4 of 4 NRC Request for Additional Information 2:
- 1. Please describe in detail how the licensee ensures that a vehicle is available to move the B.5.b portable pump and other B.5.b equipment to the appropriate place when needed.
The bulletin requested that each licensee describe in detail the controls for ensuring equipment needed to execute the mitigating strategies will be available when needed. A vehicle is typically needed to implement the strategies since the portable pump and other equipment is stored away from target areas.
STPNOC Response (2)
A pickup truck is maintained within the Protected Area to move the B.5.b portable pump. No special testing is performed because the truck is used on a daily basis for routine operations. The truck is removed from the protected area for short periods of time for general maintenance. Other trucks are readily available either within the protected area or in the owner controlled area to transport this equipment. The vehicle is used by Operations and is parked away from target areas when not in use.
