MF2457) On August 7,2013, a Category 1 public meeting was held between the U.S. Nuclear Regulatory Commission (NRC) staff and representatives of Wolf Creek Nuclear Operating Corporation (WCNOC, the licensee) and its contractors at NRC Headquarters, Rockville, Maryland. The purpose of the meeting was to discuss the licensee's water hammer mitigation project at Wolf Creek Generating Station (WCGS). The project is one part of the licensee's initiative to improve safety margins in the essential service water (ESW) system. The meeting notice and agenda are located in the Agencywide Documents Access and Management System (ADAMS) at Accession No. ML 13204A243. The licensee presented information on the background and status of the modifications to the ESW system (ADAMS Accession No. ML 13219A193). The licensee has concluded that it can complete the modifications to the ESW system under Section 50.59 of Title 10 of the Code of Federal Regulations (10 CFR) 50.59 without prior NRC approval; therefore, no licensing application is planned for the modifications. The NRC staff queried the licensee about several aspects of the modifications, the comprehensiveness of the licensee's analyses for components cooled by ESW, and potential challenges to the requirements of 10 CFR 50.59. No regulatory decisions were made at the meeting. A list of meeting attendees is enclosed. No members of the public were in attendance. No Public Meeting Feedback forms were received.
