SUBJECT:
COOPER NUCLEAR STATION - REQUEST FOR ADDITIONAL INFORMATION REGARDING REVISION OF TECHNICAL SPECIFICATION SURVEILLANCE REQUIREMENT 3.3.2.1.4 AND TABLE 3.3.2.1-1 (TAC NO. MC0629)
Dear Mr. Edington:
In [[letter::NLS2003066, License Amendment Request to Revise Technical Specification 3.5.1 to Incorporate TS Task Force (TSTF) 318 for One Low Pressure Coolant Injection (LPCI) Pump Inoperable in Each of the Two Emergency Core Cooling Systems (ECCS) Divisions|letter dated August 25, 2003]], Nebraska Public Power District (NPPD or the licensee) requested the NRC staff approve a proposed amendment to revise the Technical Specification (TS) Surveillance Requirement 3.3.2.1.4 and TS Table 3.3.2.1-1 for mathematical symbols and use of Allowable Values in the place of Analytical Limits. In a letter dated November 26, 2003, the NRC staff requested additional information, which was provided in supplemental letter dated March 9, 2004.
The NRC staff has reviewed the supplemental information provided in the March 9, 2004, submittal and determined that additional information is required in order to complete the review of the changes. As agreed upon on August 10, 2004, the licensee will respond to the following request for additional information within 45 days.
The response to question 1 stated: "The calculation Conclusion Section lists a set of permissible rod block values for AL, AV and Operating Setpoint, based on different MCPR
[minimum critical power ratio] limits... Therefore, the setpoints for the various regions were selected based on a MCPR Limit of 1.30..." How does the NPPD justify using what appears to be a slightly less conservative value of MCPR?
Sincerely,
/RA/
