Reference:

Letter from Stewart B. Minahan, Nebraska Public Power District, to the U.S.

Nuclear Regulatory Commission, dated March 24., 2008, "License Amendment Request to Revise Technical Specification 3.7.3, Reactor Equipment Cooling System"

Dear Sir or Madam:

The purpose of this letter is to submit to the Nuclear Regulatory Commission (NRC) corrected proposed Technical Specification (TS) pages for the Cooper Nuclear Station (CNS) Facility Operating License DPR-46. The letter referenced above submitted a license amendment request to revise CNS TS in accordance with the provisions of 10 CFR 50.4 and 10 CFR 50.90. The proposed amendment allows credit for the ability to align the Service Water System to the Reactor Equipment Cooling (REC) System in order to provide required cooling to the essential loads of the REC System during mitigation of the design basis loss-of-coolant accident.

As agreed between CNS and NRC, proposed Note 1 to Surveillance Requirement (SR) 3.7.3.1 is being clarified to say, "SR 3.0.1 is not applicable when both Service Water backup subsystems are OPERABLE." provides the proposed changes to the current CNS TS in marked up format. provides the final typed TS pages to be issued with the amendment. No regulatory commitments are made in this submittal.

The information submitted by this letter does not change the conclusions or the basis of the no significant hazards consideration evaluation or the environment impact evaluation provided with the reference above.
