Attachment Response to Request for Additional Information Regarding 60-Day Response to NRC Bulletin 2011-01. Mitigating Strategies

Attachment Response to Request for Additional Information Regarding 60-Day Response to Bulletin 2011-01, Mitigating Strategies Describe in detail the maintenance or testing of monitor nozzles, spray nozzles, or similar devices to ensure that they will be functional when needed.

Bulletin 2011-01 requested that each licensee describe in detail the maintenance and testing on equipment procured to support the mitigating strategies to ensure it will be functional when needed. In the context of the mitigating strategies, these devices are commonly used for firefighting and as a means to reduce the magnitude of fission product releases. The NRC staff could not determine if you performed activities to ensure that these devices will be functional when needed.

NextEra Response NextEra performs an eighteen-month equipment inventory surveillance to document the status of the B.5.b equipment including monitor nozzles, spray nozzles, couplings, and fittings in accordance with approved plant procedures.

During the inventory, the B.5.b equipment is visually inspected and the material condition is documented. B.5.b equipment deficiencies are reported in the corrective action program.

2. Describe in detail how you ensure 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.

Bulletin 2011-01 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. The NRC staff could not determine if you performed activities to ensure that a tow vehicle would be available when needed.

NextEra Response NextEra has a vehicle dedicated to the strategies in place in response to 10 CFR 50.54(hh)(2) [B.5.b]. The vehicle is parked adjacent to the building housing the B.5.b pump, hose trailer and related equipment outside the design basis threat zone. In addition, NextEra maintains a list of Seabrook Station vehicles capable of towing the B.5.b pump. The vehicles are occasionally rotated as the dedicated B.5.b tow vehicle for maintenance purposes. The B.5.b eighteen-month inventory surveillance confirms the trucks are still in service.
