SUBJECT:
SURRY POWER STATION, UNITS 1 AND 2 - REQUEST FOR ADDITIONAL INFORMATION REGARDING PROPOSED LICENSE AMENDMENT TO SUPPORT INCREASE IN THE LEAD ROD AVERAGE BURNUP LIMIT (TAC NOS. MC6435 AND MC6436)
Dear Mr. Christian:
By letter dated March 17, 2005, as supplemented by letter dated August 1, 2005, Virginia Electric and Power Company (VEPCO) submitted proposed license amendments for Surry Power Station, Units 1 and 2, to increase the lead rod average burnup to 62,000 MWD/MTU.
Based on its review of these submittals, the Nuclear Regulatory Commission (NRC) staff has determined that additional information is required to complete its review.
The NRC staffs questions are provided in the enclosure. In its March 17, 2005, submittal, VEPCO requested approval of these license amendments by September 2005 to support the spring 2006 refueling outage. As such, the NRC staff requests a response to this request for additional information within 30 days of the date of this letter.
Sincerely,
/RA/

REQUEST FOR ADDITIONAL INFORMATION PROPOSED INCREASE IN THE LEAD ROD AVERAGE BURNUP LIMIT SURRY POWER STATION, UNITS 1 AND 2 VIRGINIA ELECTRIC AND POWER COMPANY By letter (Reference 1) dated March 17, 2005, as supplemented by letter (Reference 2) dated August 1, 2005, Virginia Electric and Power Company (the licensee) requested approval of proposed amendments to the Operating Licenses and Technical Specifications for Surry Power Station, Units 1 and 2, to increase the lead rod average burnup from 60,000 MWD/MTU to 62,000 MWD/MTU. The licensee is currently restricted to a lead rod average burnup of 60,000 MWD/MTU, (References 3 and 4). In its license amendment request (LAR) the licensee stated this restriction has caused them an economic penalty to maintain the lead rod average burnup below 60,000 MWD/MTU. The NRC staff requests responses to the following questions in order to continue the review of the licensees LAR:
Questions 1.
In January of 1988, the NRC approved the use of Surry Improved Fuel (SIF) at Surry Power Station, Units 1 and 2 (Reference 5). At that time SIF was described as... similar to the OFA [Optimized Fuel Assembly] fuel but includes some features of the Vantage 5 fuel. In July of 1995, the NRC approved the use of ZIRLO as a fuel cladding at Surry Power Station, Units 1 and 2 (Reference 6). However, those documents lack the specificity deemed necessary for the current review. Please provide a detailed description of SIF from its inception and subsequent iteration(s) until its current form. It is acceptable for the description to reference a standard fuel design such as OFA and provide a detailed description of any difference and its effect.
2.
In Reference 1, the licensee requested the lead pin burnup be extended in accordance with WCAP-12488-P-A, Westinghouse Fuel Criteria Evaluation Process, (Reference 8). WCAP-12488-P-A describes a Fuel Criteria Evaluation Process (FCEP) whereby Westinghouse may make a change to a currently approved fuel design provided the change meets the criteria in WCAP-12488-P-A and notification of the change is made to the NRC.
a.
In Reference 7, Westinghouse did not explicitly list SIF as a product
... considered as licensed by the NRC under FCEP. Provide the justification for applying the FCEP to SIF.
b.
Please provide the FCEP notification for the analysis for SIF to extend the lead pin burnup to 62,000 MWD/MTU.
3.
As noted above, SIF has undergone at least one major change, the incorporation of ZIRLO cladding material. Identify the specific SIF iteration(s) covered by the FCEP notification. If the FCEP notification is to be extended to any other SIF iteration(s),
provide justification for that extension.
