UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 July 10, 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: BATIERY RESISTANCE SURVEILLANCE REQUIREMENTS (TAC NO.

ME0848)

Dear Mr. Minahan:

By application dated March 11,2009, to the U.S. Nuclear Regulatory Commission (NRC)

(Agencywide Documents Access and Management System (ADAMS) Accession No. ML090750599), Nebraska Public Power District (NPPD, the licensee) requested NRC staff approval of an amendment to the Cooper Nuclear Station facility operating license and technical specifications (TSs) to revise the battery acceptance criteria in TS Surveillance Requirements 3.8.4.2 and 3.8.4.5.

The NRC staff reviewed the information provided in your application and determined that additional information is required in order to complete its review. The enclosed questions were provided to Mr. D. Van Der Kamp of your staff on July 7, 2009. Please provide a response to the questions by August 14, 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, 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 BATTERY RESISTANCE SURVEILLANCE REQUIREMENTS COOPER NUCLEAR STATION DOCKET NO. 50-298

1.

In the license amendment request dated March 11, 2009, the licensee proposed revising Technical Specification (TS) Surveillance Requirements (SRs) 3.8.4.2 and SR 3.8.4.5 by adding a parameter of total battery resistance. Please provide the full calculations for the total resistance limits that are referenced in the TS Bases for TS SRs 3.8.4.2 and 3.8.4.5, including assumptions and supporting documentation, to show that the batteries will perform their intended design functions when operating within these limits.

2.

The words "not applicable" are used in proposed TS Table 3.8.4-1. Please explain the use of this wording, and describe how battery limits will be monitored during the performance of revised SRs 3.8.4.2 and 3.8.4.5 (e.g., describe any procedure changes between what is currently performed and what will be performed after implementation of the proposed TS changes).
