Dear Sir or Madam:

In Reference 1 Entergy submitted a request for an amendment to the TechnicalSpecifications (TS) for River Bend Station (RBS), Unit 1, modifying the existingSurveillance Requirements (SRs) related to Technical Specification 3.8.1, "AC Sources -Operating." References 3 and 5, are responses to NRC Staff requested additionalinformation.During the review an editorial changes to the numbering of the revised TS SRs wasidentified. The changes are for clarity and have no technical effect. The changes areidentified in the attachment.Aw1~ff'~

RBG-47582Page 2 of 3The changes were discussed with the NRC Project Manager. These changes are in theAttachment.There are not new commitments in this letter. Please contact Mr. J. A. Clark at (225) 381-4177, if you have any questions.I declare under penalty of perjury that the foregoing is true and correct. Executed onJuly 16, 2015.NTB/JAC/bmb
