DRAFT: Round 2 - RAI for Cooper Nuclear Station Re: LAR for Revised TS Pressure-Temperature Limits (ME7324)

Attachments: ME7324 2nd Round RAIs Email.docx Ed, By letter dated September 22, 2011 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML11272A057), Nebraska Public Power District (the licensee) submitted a license amendment request (LAR) to revise the Technical Specifications (TSs) for Cooper Nuclear Station (Cooper). The proposed LAR would revise TS 3.4.9, "RCS [Reactor Coolant System] Pressure and Temperature (P/T) Limits," to include new pressure-temperature (P-T) limits for heat-up and cool-down operations with the core critical and core not critical, as well as for pressure test conditions. The proposed P-T limits would be valid for 32 effective full power years (EFPY) of facility operation. The proposed revisions to TS 3.4.9 also would revise surveillance requirements for verifying that the reactor vessel (RV) flange and RV head flange temperatures are greater than the revised minimum operating temperature (70 degrees Fahrenheit (ºF)) specified for the proposed 32 EFPY P-T limits.

By letter dated February 29, 2012 (ADAMS Accession No. ML120590085), the U.S. Nuclear Regulatory Commission (NRC) issued a request for additional information. By letter dated March 30, 2012 (ADAMS Accession No. ML12094A118), the licensee responded to the NRCs request.

The NRC staff has reviewed and evaluated the information provided and has determined that the information specified in the attached Request for Additional Information (RAI) is needed in order to complete its review.

Please contact me if a clarifying teleconference is needed for the attached RAI.
