Dear Sir or Madam:

License Renewal Application 2012 Annual UpdateGrand Gulf Nuclear Station, Unit 1Docket No. 50-416License No. NPF-29

Letter to Nuclear Regulatory Commission, "License Renewal ApplicationGrand Gulf Nuclear Station, Unit 1," dated October 28, 2011 (GNRO2011/00093)

The purpose of this letter is to provide the Nuclear Regulatory Commission (NRC) an annualupdate to the referenced Grand Gulf Nuclear Station (GGNS) License Renewal Application(LRA), in accordance with 10 CFR 54.21 (b). During NRC review of the GGNS LRA, GGNS isrequired by 10 CFR 54.21 (b) to provide an annual report of changes to the GGNS currentlicensing basis (CLB) that materially affects the contents of the GGNS LRA, including the FinalSafety Analysis Report supplement. GGNS has completed the annual CLB review and isproviding, in the Attachment, the changes to the LRA required by this review

This letter contains no new commitments. If you have any questions or require additionalinformation, please contact Christina L. Perino at 601-437-6299.

I declare under penalty of perjury that the foregoing is true and correct. Executed on the 15th

day of August, 2012.

Section 2.3.4.2

Condensate Cleanup

The purpose of the condensate cleanup system (system code N22) is to maintain the required purity of feedwater flowing tothe reactor. Normally, demineralizers are in operation processing full condensate flow. The condensate cleanup systemconsists of eight units of deep-bed-type demineralizers (with two units as spares) that operate in parallel, and thFss pFsooatfiltsFs (with ons unit as spam) a condensate full flow filtration system used for startup. The system also includes theassociated piping, ultrasonic resin cleaner, the advanced resin cleaning subsystem, and all necessary valves,instrumentation and controls.
