Page 1 of 1 ENCLOSURE NEXTERA ENERGY DUANE ARNOLD, LLC NRC BULLETIN 2011-01, MITIGATING STRATGIES RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION The NRC staff determined that additional information was required regarding the 60-day response to Bulletin 2011-01, Mitigating Strategies (Reference 2). The following information is provided by NextEra in response to the NRC staffs request.

Question 1 Describe in detail the maintenance or testing of monitor nozzles, spray nozzles, or similar devices to ensure that they will be functional when needed.

The bulletin requested that each licensee describe in detail the maintenance and testing on equipment procured to support the mitigating strategies to ensure that it will be functional when needed. In the context of the mitigating strategies, these devices are commonly used for firefighting, spent fuel pool spray strategies, 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 annual equipment inventory to document the status of the B.5.b equipment, including nozzles, in accordance with approved plant procedures. During 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.
