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:
