SUBJECT:
COMANCHE PEAK STEAM ELECTRIC STATION, UNITS 1 AND 2 - REQUEST FOR ADDITIONAL INFORMATION RELATED TO LICENSE AMENDMENT REQUEST ASSOCIATED WITH METHODOLOGY USED TO ESTABLISH CORE OPERATING LIMITS (TAC NOS. MD5243 AND MD5244)
Dear Mr. Blevins:
By letter to the U.S. Nuclear Regulatory Commission (NRC) dated April 10, 2007, as supplemented by letters dated August 16 and November 15, 2007, TXU Generation Company LP (subsequently renamed Luminant Generation Company LLC) submitted a license amendment request for Comanche Peak Steam Electric Station (CPSES), Units 1 and 2, to revise the requirements of Technical Specification (TS) 3.1, Reactivity Control Systems, TS 3.2, Power Distribution Limits, TS 3.3, Instrumentation, and TS 5.6.5b, Core Operating Limits Report (COLR), to incorporate standard Westinghouse-developed and NRC-approved analytical methods into the lists of methodologies used to establish the core operating limits.
Based on the review of the information submitted on November 15, 2007, the NRC staff has determined that the following additional information is required to complete the review of the application:
- 1.
Submit the Axial Offset Validity Criteria methodology and its technical basis for staff review and approval.
- 2.
Explain how CPSES, Units 1 and 2, will implement the burn-up dependency of the W(z) functions, where W(z) represents the largest expected increase in Fq (the heat flux hot channel factor) from allowed plant operation.
This request for additional information (RAI) was also sent to Mr. Jimmy Seawright via e-mail on January 31, 2008, and it was agreed that the licensee will provide the response to this request by February 15, 2008.
The NRC staff considers that timely responses to RAIs help ensure sufficient time is available for NRC staff to complete its review and contribute toward the NRCs goal of efficient and effective use of staff resources.
M. If you have any questions, please contact me at (301) 415-3016.
Sincerely,
/RA/
