Dear Sir or Madam:
License Renewal Application 2013 Annual Update Grand Gulf Nuclear Station, Unit 1 Docket No. 50-416 License No. NPF-29 Letter to Nuclear Regulatory Commission, "License Renewal Application Grand Gulf Nuclear Station, Unit 1," dated October 28, 2011 (Accession No. ML11308A052)
The purpose of this letter is to provide the U.S. Nuclear Regulatory Commission (NRC) an annual update to the referenced Grand Gulf Nuclear Station (GGNS) License Renewal Application (LRA), in accordance with Title 10 Code of Federal Regulations (10 CFR) 54.21(b).
During NRC review of the GGNS LRA, GGNS is required by 10 CFR 54.21(b) to provide an annual report of changes to the GGNS current licensing basis (CLB) that materially affect the contents of the GGNS LRA, including the Final Safety Analysis Report supplement. GGNS has completed the annual CLB review and is providing, in the Attachment, the changes to the LRA required by this review. In addition, a change is being made to Appendix A.1.5 and B.1.5 of the LRA as a result of the issuance of LR-ISG-2011-03 for Buried Piping and Tanks Inspection program.
If you have any questions or require additional information, please contact Chris Robinson at 601-437-7326.
I declare under penalty of perjury that the foregoing is true and correct. Executed on the 25th day of October, 2013.
Sincerely, KJM/jas Attachment and CC: (see next page)

The program insPections ensure that environmental conditions are not causing material degradation that could result in a loss of the component's intended function. For metallic components visual inspection will be used to detect loss of material and fouling. For elastomeric and plastic components, visual inspections will be used to detect cracking and change in material properties. Visual examinations of elastomeric components are accompanied by physical manipulation such that changes in material properties are readily observable. The sample area subject to manipulation of flexible elastomeric components is at least 10 percent of the available surface area. The program manages the effects of aging for piping and components exposed to environments of air-indoor, air-outdoor, condensation, exhaust gas, lube oil, raw water, waste water, and treated water.
A.1.5 Buried Piping and Tanks Inspection Program The Buried Piping and Tanks Inspection Program manages loss of material for the external surfaces of buried and underground piping and tanks composed of any material through mitigative, and inspection activities. Preventive and mitigative actions include selection of component materials, external coatings for corrosion control, backfill quality control and the application of cathodic protection. Cathodic protection is used for additional protection of buried piping and tanks. The cathodic protection system is monitored and trended annually in accordance with NACE SP-0169 and RP-0285. Soil testing will be performed at two 1.....r-"3TU..,..<:" near that is to management review. Measured parameters will include soil resistivity, bacteria, pH, moisture, chlorides and redox potential. If the soil is determined to be corrosive then the number of inspections will increased from one to two prior to and during the period of extended operation.
