Supplemental Information Pertaining to License Amendment Request for Power Range Neutron Monitoring System (TAC No.

ME2531) - Software Evaluation Report, October 26, 2011

Dear Sir or Madam:

In Reference 1, Entergy Operations, Inc. (Entergy) submitted to the NRC a license amendment request (LAR), which proposes to revise the Grand Gulf Nuclear Station (GGNS)

Technical Specifications (TS) to reflect the installation of the digital General Electric-Hitachi (GEH) Nuclear Measurement Analysis and Control (NUMAC) Power Range Neutron Monitoring System (PRNMS).

In Reference 2, Entergy submitted to the NRC staff a response to a Request for Additional Information (RAI) pertaining to verification and validation (V&V) of software used in PRNMS.

In Reference 2, Entergy committed to provide to the NRC: (1) a software evaluation report; and (2) a V&V summary test report. The software evaluation report was submitted via Reference 3 as NEDC-33688P, Grand Gulf Nuclear Station Power Range Neutron Monitor When Attachment 1 is removed from this letter, the entire document is NON-PROPRIETARY.

GNRO-2011/00091 Page 2 of 3 Previously Developed Software Analysis and Report, which documents the evaluation and analysis of previously developed software used in PRNMS since the NRCs approval of GEH Licensing Topical Report NEDC-32510P-A, Nuclear Measurement Analysis and Control Power Range Neutron Monitor (NUMAC PRNM) Retrofit Plus Option III Stability Trip Function, October 1995. This report also determines the extent of independent module and integration testing required.

By this letter, Entergy is submitting the companion V&V summary test report, which is provided in Attachment 1 as GEH Report NEDC-33692P, Grand Gulf Nuclear Station Power Range Neutron Monitor V&V Test Summary Report. NEDC-33692P provides a summary of the V&V test program applied to PRNMS software used in the GGNS system. The results of the independent module and integration testing as determined in NEDC-33688P are summarized in NEDC-33692P.

Please note that, as discussed in various sections of NEDC-33692P, testing of the 2-Out-Of-4 Logic Modules Programmable Logic Device (PLD) has not yet been completed; therefore, it is not included in this report. The V&V summary test report for the PLD will be transmitted to the NRC by December 14, 2011.

GEH considers the information provided in Attachment 1 to be proprietary in its entirety and, therefore, requests it be withheld from public disclosure in accordance with 10 CFR 2.390.

The associated affidavit is also provided in the attachment. Because the entire attachment is proprietary, a non-proprietary, redacted version is not provided, as allowed by NRC Information Notice 2009-07, Withholding of Proprietary Information from Public Disclosure.

The No Significance Hazards Determination and the Environmental Consideration provided in Reference 1 are not impacted by this submittal.

This letter contains one new commitment identified in Attachment 2.

If you have any questions or require additional information, please contact Mr. Guy Davant at (601) 368-5756.

I declare under penalty of perjury that the foregoing is true and correct; executed on November 8, 2011.

Sincerely, MAK/ghd Attachments: 1. GEH Report NEDC-33692P, Grand Gulf Nuclear Station Power Range Neutron Monitor V&V Test Summary Report (GEH Proprietary Information)
