SUBJECT:
KEWAUNEE NUCLEAR POWER PLANT - REQUEST FOR ADDITIONAL INFORMATION FOR PROPOSED AMENDMENT REQUEST, CORE OPERATING LIMITS REPORT (TAC NO. MB5717)
By letter dated July 26, 2002, Nuclear Management Company, LLC (NMC or the licensee) submitted a request for a proposed amendment revise Kewaunee Nuclear Power Plant (KNPP)
Technical Specifications (TSs) for Core Operating Limits Report (COLR) implementation. The proposed amendment requests relocation of cycle dependent variables from the TSs to a formal report COLR.
The Nuclear Regulatory Commission (NRC) staff finds that the additional information identified in the enclosure is needed.
A draft of the request for additional information was e-mailed to Mr. G. Riste (NMC) on October 31, 2002.
A phone call was held between G. Riste (NMC), Bill Hennessey (NMC), Jeff Voski et. al.,
S. Peters (NRC), and myself on April 19, 2002, to discuss the questions to ensure that there was no misunderstanding. Also, the phone call established a mutually agreeable response date of 30 days from the date of this letter.
Please contact me at (301) 415-1446 if future circumstances should require a change in this response date.
Sincerely,
/RA/

REQUEST FOR ADDITIONAL INFORMATION (RAI)
REGARDING PROPOSED CORE OPERATING LIMITS REPORT (COLR) AMENDMENT KEWAUNEE NUCLEAR POWER PLANT DOCKET NO. 50-305
- 1.
Your proposed TS 1.0.r.b, "Shutdown Margin (SDM)," states that the SDM is calculated assuming the fuel and moderator temperatures are changed to the program temperature.
NUREG-1431, Vol. 1, Rev. 2, "Standard Technical Specifications, Westinghouse Plants,"
on the other hand, states that the SDM should be calculated assuming the temperatures are changed to the "nominal zero power design level." What is the difference between "program temperature" and "nominal zero power design level?" If there is a difference, why is it acceptable to use "program temperature" for establishing SDM?
- 2.
In TS 2.1, "Safety Limits, Reactor Core," you added peak fuel centerline limits. NUREG-1431 and WCAP-14483-A, "Generic Methodology for Expanded Core Operating Limits Report," both suggest using a peak fuel centerline temperature adjusted for fuel burnup.
How did you determine your proposed limit of 4700 degrees Farenheit and why is this value acceptable? Also, up to what levels of fuel burnup did you account for when determining this value?
- 3.
WCAP-14483-A requires that the COLR analytical methods be provided in your technical specifications (TSs). What analytical method did you use to calculate the OTDT and OPDT trip setpoints? Is this method included in your TSs? Are there any required analytical methods missing from your proposed TSs?
- 4.
NUREG-1431 shows that the maximum upper limit for Moderator Temperature Coefficient needs to be included in the TSs. Your proposed TS 3.1.f.3 does not include this limit. Why is this proposal acceptable?
- 5.
Your proposed Figure 2 of the COLR does not match the original Figure TS 3.10-1.
Specifically, the required shutdown reactivity at 0 full power equilibrium boron concentration increased from 2000 pcm to 2200 pcm. Why is this change acceptable?
Did you perform a 50.59 evaluation for this change?
- 6.
Kewaunee TS 3.8.a.5, "Refueling Operations," requires that a shutdwon margin of greater than 5 percent Delta k/k be maintained during refueling operations. However, you did not retain this requirement in your proposed COLR. Explain why this omitting this value from the COLR is acceptable.
