UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 February 1, 2010 Mr. Mark J. Ajluni Manager, Nuclear Licensing Southern Nuclear Operating Company, Inc 40 Inverness Center Parkway Post Office Box 1295 Birmingham, AL 35201
SUBJECT:
FARLEY NUCLEAR PLANT, UNIT NOS. 1 AND 2, REQUEST FOR ADDITIONAL INFORMATION REGARDING REQUESTS FOR RELIEF (TAC NO. ME1124)
Dear Mr. Ajluni:
By letter to the U.S. Nuclear Regulatory Commission (NRC) dated April 22, 2009, Southern Nuclear Operating Company, Inc. (SNC), submitted request for relief FNP-ISI-ALT-08, Version 1.0, from certain examination qualification requirements of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code),Section XI, at the Joseph M. Farley Nuclear Plant, Unit 2. Specifically, SNC proposes to use a contracted examination vendor that has demonstrated ability to meet a depth sizing qualification requirement with a root mean square error (RMSE) of 0.189 inch instead of the 0.125 inch required for Supplement 10, an RMSE of 0.367 inch instead of the 0.125 inch required for Supplement 2, and an RMSE of 0.245 inch instead of the 0.125 inch for Supplements 10 and 2 combined. It is the NRC staff's understanding that the Supplement 2 qualification is not a stand-alone qualification. Given that understanding, please discuss why SNC's request for relief provides an RMSE for Supplement 2 examinations.
Please provide a response within thirty (30) days of the date of this letter.
Sincerely,
~
