SUMMARY

OF CONFERENCE CALL HELD ON JULY 30, 2014, BETWEEN THE U.S. NUCLEAR REGULATORY COMMISSION AND ENTERGY NUCLEAR OPERATIONS, INC., REGARDING A DRAFT REQUEST FOR ADDITIONAL INFORMATION ON REMOVAL OF CERTAIN AGING MANAGEMENT REVIEW ITEMS Representatives of the U.S. Nuclear Regulatory Commission (NRC or the staff) and representatives of Entergy Nuclear Operations, Inc. (Entergy or the applicant), held a conference call on July 30, 2014, regarding draft request for additional information (RAI) 3.4.2.1-1 transmitted to Entergy by e-mail dated June 30, 2014. A list of the participants is enclosed.

By letter dated September 26, 2012, Entergy provided changes to aging management review (AMR) tables in its license renewal application (LRA). Upon review of the information, the staff questioned the removal of specific AMR items that were previously identified as subject to cracking due to fatigue, which were to be managed by the metal fatigue time-limited aging analysis (TLAA). Therefore, by e-mail dated June 30, 2014, the staff sent a draft RAI to Entergy regarding the basis provided for removal of the specific AMR items.

After subsequent discussion among the NRC staff, it requested a call with Entergy to provide clarification on its draft RAI. During the call, the staff stated that what it needed to understand was whether Entergys basis for removing the AMR items was that the aging effect did not apply because of a temperature threshold or if Entergy was saying that it eliminated the TLAA.

Entergy stated that the TLAA does not apply to the specific components because the components do not experience the temperatures where cracking due to fatigue is an aging effect of concern; however, the TLAA still exists and had not been eliminated. Entergy stated that its approach is supported by information in the EPRI Fatigue Management Handbook, and Appendix H to the EPRI Non-Class 1 Mechanical Implementation Guideline and Mechanical Tools. Appendix H to EPRI Non-Class 1 Mechanical Implementation Guideline and Mechanical Tools suggests that cracking due to fatigue is not a concern for non-reactor coolant pressure boundary in-line stainless steel components if the maximum temperature of the fluid is less than 270 °F, and is not a concern for non-reactor coolant pressure boundary in-line carbon steel components if the maximum fluid temperature is less than 220 °F.

The staff considered the information in Appendix H to the EPRI Non-Class 1 Mechanical Implementation Guideline and Mechanical Tools. Based on the staffs review of the information, it determined that no additional information is required. Therefore, the staff will not issue a formal RAI.

The applicant had an opportunity to comment on this summary.
