SUMMARY

OF TELEPHONE CONFERENCE CALL DAVIS-BESSE LICENSE RENEWAL APPLICATION June 21, 2012

The U.S. Nuclear Regulatory Commission (NRC or the staff) and representatives of FirstEnergy Nuclear Operating Company (FENOC or the applicant) held a telephone conference call on June 21, 2012, to discuss and clarify the following response to requests for additional information (RAIs) concerning the Davis-Besse license renewal application (LRA).

RAI 4.7.5.1-1 related to LRA Section 4.7.5.1, "Reactor Coolant System Loop 1 Cold Leg Drain Line Weld Overlay Repair."

Discussion:

The staff stated that in response to RAI 4.7.5.1-1, the applic ant cited a summary calculation package that was prepared to document the design an d analysis of the Davis-Besse reactor coolant pump 1-1 inlet cold leg drain line nozzle-to-elbow weld overlay. The package included summaries of an American Society of Mechanical Engineer's Boiler and Pressure Vessel (ASME)

Code Section III evaluation (Calculation Number DB-06Q-304, Rev. 1) and a fatigue crack growth analysis (Calculation Number DB-06Q-307, Rev. 0). The staff stated that LRA Section 4.7.5.1 only identified the ASME Code Section III evaluation as a TLAA. The staff further stated that its position is that the fatigue crack growth analysis is al so a TLAA requiring disposition for license renewal.

The applicant agreed that the fa tigue crack growth analysis is a TLAA. The applicant also agreed to provide a supplemental res ponse to RAI 4.7.5.1-1 to disposition the TLAA associated with the fatigue crack growth analysis. Since the subject analysis is not docketed, it was also agreed that the supplemental response would provide sufficient details (e.g., address residual stresses, primary water stress corrosion cracking, etc.) to support the staff's review. The applicant stated that the target date for submittal of the supplemental response is July 10, 2012.

There was no further discussion, and the call was concluded.

Action: The applicant will provide a supplemental response to RAI 4.7.5.1-1.
