SUBJECT:
CRYSTAL RIVER UNIT 3 REQUEST FOR ADDITIONAL INFORMATION RE: PROPOSED LICENSE AMENDMENT REQUEST ON POWER UPRATE TO 2568 MWT (TAC NO. MB5289)
Dear Mr. Young:
By letter dated June 5, 2002, you submitted an amendment application to revise the Crystal River Unit 3 (CR-3) Improved Technical Specifications Section 1.1 and License Condition 2.C.(1) to allow operation up to 2568 MWt. The enclosed Request for Additional Information (RAI) was previously discussed with your staff on September 10, 2002.
For the staff to complete its review on schedule, your response to this RAI is requested no later than October 11, 2002. This date was mutually agreed upon in a telephone conversation with Paul Infanger on September 10, 2002. If you need to revise the target date, please call me at the earliest opportunity at 301-415-2020.
Sincerely,
/RA/

REQUEST FOR ADDITIONAL INFORMATION POWER UPRATE TO 2568 MWT CRYSTAL RIVER UNIT 3 1)
Section 4.7.2.4 of Attachment A to the amendment request indicates the RTPTS value at end of license (EOL) for the limiting beltline material, upper shell longitudinal welds WF-18 and WF-8, is 206.0 oF. The attachment also indicates that neutron embrittlement analyses were performed using a 7-percent increase in neutron fluence and the chemical composition reported in Reference 7, BAW-2325, Revision 1, Response to Request for Additional Information (RAI) Regarding Reactor Pressure Vessel Integrity, January 1999. This report identifies the EOL RTPTS value for the upper shell longitudinal weld as 215.7 oF, which is greater than the value reported in this amendment. Since the neutron fluence was assumed to increase in this evaluation, the RTPTS should have increased.
Explain this discrepancy and provide the following information:
a) the neutron fluence at the clad-base metal interface for the upper shell longitudinal weld at EOL, b) the amounts of copper and nickel for the upper shell longitudinal weld, c) the unirradiated reference temperature for the upper shell longitudinal weld, and d) the margin value utilized in the RTPTS evaluation for the upper shell longitudinal weld.
2)
In order to satisfy the reactor vessel Charpy upper-shelf energy requirements of Appendix G, 10 CFR Part 50, Florida Power Corporation has performed equivalent margins analyses for the beltline welds. What is the impact of the power uprate on the equivalent margins analyses? Provide the neutron fluence at the 1/4 thickness at EOL for the beltline welds and describe the impact of this neutron fluence on the equivalent margins analyses.
