October 17, 2006 Mr. Karl W. Singer Chief Nuclear Officer and Executive Vice President Tennessee Valley Authority 6A Lookout Place 1101 Market Street Chattanooga, TN 37402-2801
SUBJECT:
BROWNS FERRY NUCLEAR PLANT, UNIT 1 REVIEW OF PROPOSED AMENDMENT FOR FIVE PERCENT INCREASE IN THERMAL POWER (TAC NO. MD3048) (TS-431)
Dear Mr. Singer:
The purpose of this letter is to inform you of the U.S. Nuclear Regulatory Commission (NRC) staffs review methodology for your September 22, 2006, license amendment request. This methodology was discussed with your staff on October 10, 2006. On September 22, 2006, the Tennessee Valley Authority (the licensee) submitted a request to supplement the Browns Ferry Nuclear Plant (BFN) Unit 1 June 28, 2004, request. The June 28, 2004, amendment request involves a change in licensed thermal power from 3293 megawatt thermal (MWt) to 3952 MWt, an approximate 20 percent increase in thermal power (commonly referred to as an extended power uprate (EPU)). The September 22, 2006, supplement requested approval of an increase in licensed thermal power from 3293 MWt to 3458 MWt with an attendant 30-pounds per square inch increase in reactor pressure. This represents an approximate 5-percent increase above the original licensed thermal power (OLTP) of 3293 MWt, and is commonly referred to as a stretch power uprate. The NRC staff has reviewed the information provided and determined that sufficient information has been provided to begin the technical review of your application.
In the submittal, TVA states that the analyses and evaluations previously performed for EPU operation at 120 percent OLTP in the PUSAR (Power Uprate Safety Analysis Report) support and/or bound operation at lesser power levels, subject to the operating restrictions and limitations that would be applicable. In other cases, the staff requested and you have agreed to provide cycle-specific analyses (105% power level) e.g, safety limit minimum critical power ratio. In its review of your stretch power uprate request, the NRC staff will use the information supplied in support of your EPU application to determine if there is reasonable assurance that operation at the stretch power uprate conditions is consistent with the Commissions regulations. The results of this review will be documented in a safety evaluation. This safety evaluation will not contain any conclusions regarding the acceptability of your analysis in support of operation at EPU conditions.
The NRC staff will subsequently review the information supplied in support of your EPU application in its entirety to determine if there is reasonable assurance that operation at EPU conditions is consistent with the Commissions regulations. This review will be documented in a separate, stand-alone safety evaluation that will specifically address each topic delineated in
K. Singer the template safety evaluation provided in the Review Standard. The amendment package, including the safety evaluation, will be reviewed in accordance with standard practice, which includes review by the Advisory Committee for Reactor Safeguards.
If you have any questions, please contact the BFN Unit 1 Project Manager, Ms. Margaret Chernoff, at (301) 415-4041.
Sincerely,
/RA/
