Final Request for Additional Information - River Bend CBAC Request (L-2017-LLA-0291)Final Request for Additional Information (EPID L-2017-LLA-0291)

On February 16, 2018, the U.S. NRC staff sent River Bend Station (RBS, the licensee) a draft Request for Additional Information (RAI). The RAI questions relate to a license amendment request (LAR) that proposes to increase the allowed outage time and add a new technical specification (TS) for the Control building air conditioning system for RBS.

On February 27, 2018, the NRC staff held a clarification call with RBS; following the call, the licensee stated that it understood all of the questions and would respond within 30 days of the date of this email. If RBS does not respond by this date, the requested completion date for the LAR may not be met by the NRC.

The NRC staff also informed the licensee that a publicly av ailable version of this final RAI would be placed in the NRC's Agencywide Documents Access and Management System (ADAMS).

By letter dated September 8, 2017 (ADAMS Accession No. ML17255A463, the Entergy requested an amendment to the Operating License related to a new TS for the control building air conditioning system for RBS. The amendment proposes to add TS 3.7.7 "Control Building Air Conditioning (AC) System," and associated limiting condition for operation and surveillance requirements to allow completion of minor

maintenance activities and reduce the need for plant s hutdowns. The NRC staff requires additional information to complete its review of this request as detailed in the attached document.
