Entergy Letter; Response to Request for Additional Information onApplication for TSTF-523, "Generic Letter 2008-01, Managing GasAccumulation," (RBG-47557) Dated April 28, 2015Dear Sir or Madam:In Reference 1, Entergy Operations, Inc. (Entergy) submitted a request for an amendment.to the Technical Specifications (TS) for River Bend Station (RBS), Unit 1. The proposedamendment modifies the existing Surveillance Requirements (SRs) related to gasaccumulation for the Emergency Core Cooling Systems (ECCS). This request was basedupon Technical Specification Task Force (TSTF) Improved Standard TechnicalSpecification Change Traveler, TSTF-523, "Generic Letter 2008-01, Managing GasAccumulation."This initial submittal contained markups of the proposed specifications which were not infinal form.Ai -

RBG-47605Page 2 of 3In Reference 3 in a response to an NRC Staff request for additional information (RAl),RBS determined the notes to specifications SR 3.4.9.2 and SR 3.4.10.2 were no longerrequired. Revised markups of these pages were not included in that submittal.Attachment 1 provides the final technical specification pages. There are no newcommitments in this letter, If you have any questions or require additional information,please contact Mr. J. A. Clark at (225) 381-4177.I declare under penalty of perjury that the foregoing is true and correct, executed onAugust 20, 2015.NTB/JAC/bm bAttachments:1.Final Technical Specification Pagescc: Regional AdministratorU.
