Dear Mr. Carns:
SUBJECT:
WOLF CREEK GENERATING STATION - REQUEST FOR ADDITIONAL INFORMATION REGARDING PROPOSED POWER RERATE (TAC NO. M85311)
Enclosed are questions related to the Wolf Creek Nuclear Operating Corporation's submittal dated January 5,1993, which proposed a revision to the operating license and technical specifications to allow an increase in rated thermal power.
The reporting requirements contained in this letter affect fewer than ten respondents; therefore, OMB clearance is not required under Public Law 96-511.
Sincerely, Original Signed By William D. Reckley, Project Manager Project Directorate IV-2 Division of Reactor Projects III/IV/V Office of Nuclear Reactor Regulation

I Enclosure RE0 VEST FOR ADDITIONAL INFORMATION PROPOSED WOLF CREEK POWER RERATE 1.
Provide additional information related to the evaluations performed to verify environmental qualification of equipment.
Discussions should address equipment located inside and outside of containment.
2.
Provide a discussion regarding the review of licensing basis analyses that are located largely outside of the Updated Safety Analysis Report (USAR) (e.g., station blackout, anticipated transients without scram, individual plant evaluation).
3.
Provide a discussion regarding plans for USAR update and/or other configuration control practices which will address the large number of evaluations performed for the rerate.
In particular, address the concern that licensing / design basis analyses, while bounding, may not reflect planned operating conditions. How will future changes to the facility capture not only the specific change but also the rerated operating conditions?
4.
Provide clarification regarding the pressurizer subcompartment analysis.
What evaluations and reanalyses were performed?
5.
Clarify the discussion regarding the condensate storage tank (CST) inventory and the adequacy of the existing technical specification considering both the required inventory and allowances for configuration and losses.
6.
Provide additional details regarding initial conditions assumed for the containment pressure and temperrture analyses. Clarify the assumptions related to the maximum safety injection (SI) case.
