Dear 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 proposed amendment modifies the existing Surveillance Requirements (SRs) related to gas accumulation for the Emergency Core Cooling Systems (ECCS). This request was based upon Technical Specification Task Force (TSTF) Improved Standard Technical Specification Change Traveler, TSTF-523, "Generic Letter 2008-01, Managing Gas Accumulation."

This initial submittal contained markups of the proposed specifications which were not in final form.

Ai¢-_

RBG-47605 Page 2 of 3 In 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 longer required. Revised markups of these pages were not included in that submittal. provides the final technical specification pages. There are no new commitments 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 on August 20, 2015.
