UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 November 3, 2009 Mr. Stewart B. Minahan Vice President-Nuclear and CNO Nebraska Public Power District 72676 648A Avenue Brownville, NE 68321
SUBJECT:
COOPER NUCLEAR STATION - REQUEST FOR ADDITIONAL INFORMATION RE: RESPONSE TO GENERIC LETTER 2008-01, "MANAGING GAS ACCUMULATION IN EMERGENCY CORE COOLING, DECAY HEAT REMOVAL, AND CONTAINMENT SPRAY SYSTEMS" (TAC NO. MD7815)
Dear Mr. Minahan:
By letter dated October 10, 2008, as revised by letters dated March 2 and May 7,2009, Nebraska Public Power District (NPPD, the licensee) provided a response for Cooper Nuclear Station to U.S. Nuclear Regulatory Commission (NRC) Generic Letter 2008-01, "Managing Gas Accumulation in Emergency Core Cooling, Decay Heat Removal, and Containment Spray Systems."
The NRC staff has reviewed the information provided by NPPD and determined that additional information is required in order to determine that the licensee has acceptably demonstrated "that the subject systems are in compliance with the current licensing and design bases and applicable regulatory requirements, and that suitable design, operational, and testing control measures are in place for maintaining this compliance," as stated in Generic Letter 2008-01.
The enclosed questions were provided to Mr. D. Van Der Kamp of your staff on October 30, 2009. Please provide a response to the questions by December 18, 2009.
The NRC staff considers that timely responses to requests for additional information help ensure sufficient time is available for NRC staff review and contribute toward the NRC's goal of efficient and effective use of NRC staff resources. If circumstances result in the need to revise the requested response date, please contact me at (301) 415-2296.
Sincerely, CFJr Carl F. Lyon, Project Manager Plant Licensing Branch IV Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation Docket No. 50-298

REQUEST FOR ADDITIONAL INFORMATION RESPONSE TO GENERIC LETTER 2008-01 COOPER NUCLEAR STATION DOCKET NO. 50-298 The U.S. Nuclear Regulatory Commission (NRC) staff has reviewed the information provided by Nebraska Public Power District (the licensee) for Cooper Nuclear Station (CNS) in its letter dated October 10,2008, as revised by letters dated March 2 and May 7,2009, and determined that additional information is necessary to determine that the licensee has acceptably demonstrated "that the subject systems are in compliance with the current licensing and design bases and applicable regulatory requirements, and that suitable design, operational, and testing control measures are in place for maintaining this compliance," as stated in NRC Generic Letter (GL) 2008-01.
Guidance on NRC staff expectations is provided by Reference 1, which is generally consistent with the Nuclear Energy Institute (NEI) guidance provided to industry in Reference 2, as clarified in later NEI communications. The NRC staff recommends that the licensee consult Reference 1 when responding to the following questions:
- 1.
Discuss the control and revision of work packages due to change in maintenance work scope, including review and reauthorization of the package and any new temporary changes.
- 2.
Briefly describe the monitoring of pump operation in all modes and specialized monitoring of appropriate plant parameters during shutdown operations.
- 3.
In several sections of the response, the licensee mentioned that procedures will be revised in order to incorporate the use of ultrasonic testing (UT) in assuring the in-scope systems are filled. Please expound further on how and where UT will be used to ensure said systems are filled.
- 4.
Training was not identified in the GL (Reference 3) but is considered to be a necessary part of applying procedures and other activities when addressing the issues identified in the GL as the licensee has recognized. Please provide a brief description of training.
