CLINTON POWER STATION, UNIT 1 - REQUEST FOR ADDITIONAL INFORMATION REGARDING LICENSE AMENDMENT REQUEST TO REVISE TECHNICAL SPECIFICATION 5.5.2, "PRIMARY COOLANT SOURCES OUTSIDE CONTAINMENT" (TAC NO. MF5291)
==Dear Mr. Hanson:==
By application dated November 17, 2014 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML14321A882), Exelon Generation Company, LLC (the licensee) submitted a request to revise Technical Specification (TS) 5.5.2, "Primary Coolant Sources Outside Containment," for Clinton Power Station (CPS), Unit 1. Currently, TS 5.5.2 requires that an integrated leak test be performed on each system subject to TS 5.5.2 at refueling cycle intervals or less. The proposed change would require this test to be performed at least once per 24 months. The reason for the request is to support the CPS transition from 2-year to 1-year refueling cycles. The U.S. Nuclear Regulatory Commission staff is reviewing the application and has determined that additional information is needed to complete its review.
A response to the enclosed request should be provided by June 19, 2015. This request was discussed with Mr. Tim Byam of your staff on April 22, 2015.
