This TS change modifies the fan requirements to indicate the number of fans required to be operable per cell, rather than per train. In addition, a note will be modified to delete the allowance for an entire cell to be out-of-service because it incorrectly indicates that four fans can be out of service in a single cell. The note modification also removes the implication that covers are not needed to maintain an operable train. In concert with the above change, the wet and dry bulb temperature limits are lowered to account for the increased heat duty resulting from the Replacement Steam Generators.

TAC No. ME7342 - Request for Additional Information Attachments: RAI from SBPB_ML120450859.docx Billy, By letter dated October 13, 2011, as supplemented by letters dated November 25, 2011, and January 18, 2012, Entergy Operations, Inc. (Entergy) made application to amend the Technical Specifications (TS) 3/4.7.4 Table 3.7-3, "Ultimate Heat Sink Minimum Fan Requirements Per Train." of the Waterford Steam Electric Station, Unit 3 (Waterford 3).

This TS change modifies the fan requirements to indicate the number of fans required to be operable per cell, rather than per train. In addition, a note will be modified to delete the allowance for an entire cell to be out-of-service because it incorrectly indicates that four fans can be out of service in a single cell. The note modification also removes the implication that covers are not needed to maintain an operable train. In concert with the above change, the wet and dry bulb temperature limits are lowered to account for the increased heat duty resulting from the Replacement Steam Generators.

The NRC Staff has reviewed the amendment request and determined that we require additional information to complete our review. A request for additional information is attached.

The staff requests you to provide a response to the RAI within 30 days from the date of this email. If this is not feasible, please let me know, in advance, when the response will be sent.

Thanks
