CATAWBA NUCLEAR STATION, UNIT 2 RE: REQUEST FOR ADDITIONAL INFORMATION (TAC NO. MC4993)
Dear Mr. Jamil:
By letters dated October 19 and December 2, 2004, Duke Energy Corporation submitted for Nuclear Regulatory Commission (NRC) staff review, an evaluation of a flaw indication in the reactor coolant hot leg to steam generator nozzle connection, that was discovered on October 7, 2004, during the 13th refueling outage for Catawba Nuclear Station, Unit 2. The NRC staff has reviewed the submittals and has determined that additional information is required, as identified in the Enclosure.
We discussed these issues with your staff on May 5, 2005. Your staff indicated that you would attempt to provide your response by June 30, 2005.
Please contact me at (301) 415-1842, if you have any questions on these issues.
Sincerely,

REQUEST FOR ADDITIONAL INFORMATION DUKE POWER COMPANY CATAWBA NUCLEAR STATION, UNIT 2 DOCKET NO. 50-414 The Nuclear Regulatory Commission (NRC) staff has reviewed the licensees submittals dated October 19 and December 2, 2004, regarding an evaluation of a flaw indication in the reactor coolant hot leg to steam generator nozzle connection, that was discovered on October 7, 2004, during the 13th refueling outage for Catawba Nuclear Station, Unit 2. The NRC staff has identified the following information that is needed to enable the continuation of its review.
- 1. In the letter dated October 19, 2004, you stated, [t]he indication was located near the interface between the safe-end and field weld at the bottom of the nozzle. Please confirm whether the flaw indication is in the safe end or in the field weld.
- 2. In the letter dated October 19, 2004, you stated, [t]his letter submits the fracture mechanics analysis to the NRC (see attachment). The NRC staff did not find in your submittal an evaluation of the detected flaw indication (1 inch long circumferential embedded flaw, 1.01 inches from the outside diameter of the pipe) using WCAP-15658-P, Revision 1. Please provide this information. The response should include the WCAP figure number (Figure A-4.6, Figure A-4.7, Figure A-4.8, or Figure A-4.9) that you used for evaluation of the detected flaw in the steam generator primary nozzle weld region. The response should also include the depth of the detected flaw (the size of the flaw in the wall thickness direction).
- 3. On Page 3-1 of WCAP-15658-P, Revision 1, Flaw Evaluation Handbook for Catawba Unit 2 Steam Generator Primary Nozzle Weld Regions, November 2004, it is stated, [t]he stress intensity factor calculation for an embedded flaw was taken from the work by Shah and Kobayashi [6] which is applicable to an embedded flaw in an infinite medium....This expression has been shown to be applicable to embedded flaws in a thick-walled pressure vessel in a paper by Lee and Bamford [7]. Please demonstrate the applicability of Kobayashis formulas for embedded flaws to your current application by addressing (1) the difference between the finite geometry of the current application and an infinite medium discussed in Kobayashis paper, and (2) the difference between the ratio of plate thickness to crack depth, t/2a, of the current application and that discussed in Kobayashis paper. Provide Reference 7 of WCAP-15658-P, Revision 1 (Paper 83-PVP-92 by Lee and Bamford) if you believe it would help your explanation.
- 4. On Page 3-4 of WCAP-15658-P, Revision 1, it is stated, NRC procedures exist for addressing the impact of thermal aging on fracture toughness for full-service life. The approved procedures were applied to the nozzle safe end to pipe weld, as well as to the cast piping itself.
Provide the specific document (e.g., NUREG number) and parameters used (e.g., ferrite content) in your determination of fracture toughness for full-service life using NRC procedures.
Explain how you use these NRC procedures to determine the first set of proprietary JIc and Tmat given on Page 3-4. It is further stated on this page, [e]ven with thermal aging, equivalent to full service for SAW welds, the tearing modulus remains high (>100) and the unaged toughness, JIc, is not significantly reduced. Provide information supporting this statement.
