SUBJECT:

DRAFT SAFETY EVALUATION FOR NUCLEAR ENERGY INSTITUTE TOPICAL REPORT MATERIALS RELIABILITY PROGRAM (MRP): TECHNICAL BASIS FOR PREMPTIVE WELD OVERLAYS FOR ALLOY 82/182 BUTT WELDS IN PRESSURIZED WATER REACTORS (MRP-169) (TAC NO. MD8005)

Dear Mr. Riley:

By letter dated September 7, 2005, the Nuclear Energy Institute (NEI) submitted Topical Report (TR) Material Reliability Program (MRP): Technical Basis For Preemptive Weld Overlays For Alloy 82/182 Butt Welds in Pressurized Water Reactors (MRP-169), Revision 0, to the U.S.

Nuclear Regulatory Commission (NRC) staff for review. In a letter to NEI dated April 26, 2007, the NRC discontinued its review of TR MRP-169, Revision 0. After an August 23, 2007, public pre-submittal meeting with the NRC staff, the NEI and the Electric Power Research Institute stated that they would submit the necessary documentation to re-initiate the NRC's review of TR MRP-169, Revision 0. By letter dated January 9, 2008, NEI re-submitted for NRC staff review TR MRP-169, Revision 0. The transmittal memo for the January 9, 2008, letter from NEI states that this document is considered to be non-proprietary.

By letters dated August 3, 2006 and April 7, 2008, the NRC staff issued a request for additional information (RAI) to NEI to support the review of TR MRP-169. By letters dated January 9, 2008, May 2, 2008, March 2, 2009, November 30, 2009, and February 3, 2010, NEI responded to the NRC staff's RAIs and provided supplemental information in support of the NRC staff's review of TR MRP-169. Enclosed for NEI review and comment is a copy of the NRC staff's draft safety evaluation (SE) for the TR.

J. Riley 2 Twenty working days are provided for you to comment on any factual errors or clarity concerns contained in the SE. The final SE will be issued after making any necessary changes and will be made publicly available. The NRC staff's disposition of your comments on the draft SE will be discussed in the final SE.

To facilitate the NRC staff's review of your comments, please provide a marked-up copy of the draft SE showing proposed changes and provide a summary table of the proposed changes.

If you have any questions, please contact Tanya Mensah at 301-415-3610.

Sincerely, /RA/ Stacey L. Rosenberg, Chief Licensing Processes Branch Division of Policy and Rulemaking Office of Nuclear Reactor Regulation

Project Nos. 669 and 689
