UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 August 11, 2015 Mr. Bryan C. Hanson President and Chief Nuclear Officer (CNO)
Exelon Generation Company, LLC Exelon Nuclear 4300 Winfield Road Warrenville, IL 60555
SUBJECT:
CLINTON POWER STATION, UNIT 1 - CORRECTION LETTER FOR SAFETY EVALUATION FOR ALTERNATIVES FROM ASME OM CODE REQUIRED FREQUENCY (TAC NOS. MF5344 AND MF5345)(RS-14-291 AND RS-14-292)
Dear Mr. Hanson:
By letters dated December 1, 2014, as supplemented by letters dated March 26, and June 3, 2015 (Agencywide Documents Access and Management System (ADAMS) Accession Nos.
ML14335A540, ML14335A541, ML15085A458 and ML15154A957, respectively) Exelon Generation Company, LLC (EGC), submitted alternatives to the required refueling outage frequency for cold and refueling shutdown justification valves, and motor operated valves at Clinton Power Station, Unit 1. On July 15, 2015, the U.S. Nuclear Regulatory Commission (NRC) staff issued a safety evaluation (SE) approving the proposed alternatives. On July 23, 2015, Mr. Timothy Byam notified the NRC staff of a minor error in the SE. The Table on page 4 of the SE should be corrected as follows to reflect the appropriate outages for the identified test failures. The changes to the table below are in bold:
Valve (RFJ#) Test Failure Outage (test type)~
1E12-F041B (RFJ-005) C1R11(CC) 1E22-F005 (RFJ-005) C1R11 (CC) 1E51-F066 (RFJ-002) C1R11(CC) 1B21-F032A (RFJ-003) C1R11(CC) 1E21-F006 (RFJ-005) C1R12 (CC) 1E22-F005 (RFJ-005) C1 R12 (CC) 1B21-F032B (RFJ-003) C1R12 (CC) 1E51-F066 (RFJ-002) C1R13(CC) 1CM067 (RFJ-013) C1 R14 (CC) 1E51-F066 (RFJ-002) C1 R14 (CC) 1E12-F041B (RFJ-005) C1 R14 (CO)
B. Hanson These corrections do not alter any findings or conclusions Sincerely, IRA!
