SUBJECT:
WOLF CREEK GENERATING STATION- REQUEST FOR ADDITIONAL INFORMATION RE: LICENSE AMENDMENT REQUEST TO ADOPT TSTF-523, REVISION 2, "GENERIC LETTER 2008-01, MANAGING GAS ACCUMULATION" (TAC NO. MF5280)
Dear Mr. Heflin:
By letter dated November 20, 2014, Wolf Creek Nuclear Operating Corporation (the licensee) submitted to the U.S. Nuclear Regulatory Commission (NRC) a license amendment request to revise the Wolf Creek Generating Station (WCGS) Technical Specifications (TS) requirements to address NRC Generic Letter 2008-01, "Managing Gas Accumulation in Emergency Core Cooling, Decay Heat Removal, and Containment Spray Systems," as described in Technical Specification Task Force (TSTF) Traveler TSTF-523, Revision 2, "Generic Letter 2008-01, Managing Gas Accumulation."
The NRC staff has reviewed the information provided in your application and determined that additional information is required in order to complete its formal review. The enclosed questions were provided to Mr. S. Wideman of your staff on February 9, 2015. Please provide a response to the enclosed questions within 45 days of the date of this letter. If you have any questions, please contact me at 301-415-2296 or via e-mail at fred.lyon@nrc.gov.
Sincerely, Carl F. Lyon, Project Manager Plant Licensing Branch IV-1 Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation Docket No. 50-482 Enclosure Request for Additional Information cc w/encl: Distribution via Listserv
REQUEST FOR ADDITIONAL INFORMATION LICENSE AMENDMENT REQUEST TO ADOPT TSTF-523, REVISION 2 WOLF CREEK NUCLEAR OPERATING CORPORATION WOLF CREEK GENERATING STATION DOCKET NO. 50-482 By letter dated November 20, 2014 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML14330A247), Wolf Creek Nuclear Operating Corporation (the licensee) submitted to the U.S. Nuclear Regulatory Commission (NRC) a license amendment request to revise the Wolf Creek Generating Station (WCGS) Technical Specifications (TS) requirements to address NRC Generic Letter 2008-01, "Managing Gas Accumulation in Emergency Core Cooling, Decay Heat Removal, and Containment Spray Systems," as described in Technical Specification Task Force (TSTF) Traveler TSTF-523, Revision 2, "Generic Letter 2008-01, Managing Gas Accumulation."
The NRC staff requests the following additional information in order to complete its review of the request.
Reactor Systems Branch (SRXB) Questions:
- 1. What were the historic void volumes found that are applicable to performance of TS surveillance requirements (SRs) 3.5.2.3 and 3.6.6.9, and how did these compare to the acceptance criteria? How do those void volumes compare to follow-up calculations that were performed if the original criteria were not met?
- 2. Is the WCGS design basis "no gas?" If not, please provide the documentation that established the design basis.
- 3. Please provide a description of the process used to restore the plant to the design basis condition at the earliest practical time following discovery of a gas volume that exceeds the design basis.
- 4. Please describe the methodology used to determine gas volumes that do not jeopardize operability that are applicable to SRs 3.5.2.3 and 3.6.6.9.
- 5. How is potential leakage from the reactor coolant system addressed?
