Mr. Mark B. Bezilla Site Vice President UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 August 8, 2017 FirstEnergy Nuclear Operating Company Mail Stop A-DB-3080 5501 North State Route 2 Oak Harbor, OH 43449-9760
SUBJECT:
DAVIS-BESSE NUCLEAR POWER STATION, UNIT NO. 1 - LICENSE RENEWAL COMMITMENT NO. 42 (CAC NO. MF9704)
Dear Mr. Bezilla:
Section 2.C(11), "License Renewal Conditions," of Renewed Facility Operating License No. NPF-3 specifies that the Commitments in Appendix A of NUREG-2193, Supplement 1, "Safety Evaluation Report Related to the License Renewal of Davis-Besse Nuclear Power Station [DBNPS]," published April 2016, 1 are part of the DBNPS Updated Final Safety Analysis Report. License renewal Commitment No. 42 in Appendix A of NUREG-2193, Supplement 1, states that FirstEnergy Nuclear Operating Company (FENOC, the licensee) will erhance the DBNPS fatigue monitoring program to:
Evaluate additional plant-specific component locations in the reactor coolant pressure boundary that may be more limiting than those considered in NUREG/CR-6260.[21 This evaluation will include identification of the most limiting fatigue location exposed to reactor coolant for each material type (i.e., [carbon steel] CS, [low-alloy steel] LAS, [stainless steel] SS, and [nickel-based alloy]
NBA) and that each bounding material/location will be evaluated for the effects of the reactor coolant environment on fatigue usage. Nickel-based alloy items will be evaluated using NUREG/CR-6909.Pl Submit the evaluation to the NRC
[Nuclear Regulatory Commission] 1 year prior to the period of extended operation.
By letter dated April 21, 2016,4 as supplemented by letters dated September 26, 2016, and February 22 and May 12, 2017,5 FENOC provided information regarding the fatigue monitoring program evaluation for DBNPS in accordance with license renewal Commitment No. 42. The supplemental letters were in response to requests for additional information issue,d by the NRC on August 26, 2016, and January 23, 2017.6 1 Agencywide Documents Access and Management System (ADAMS) Accession No. ML16104A350.
2 NUREG/CR-6260, "Application of NUREG/CR-5999 Interim Fatigue Curves to Selected Nuclear Power Plant Components," dated February 1995, ADAMS Accession No. ML031480219.
3 NUREG/CR-6909, "Effect of LWR Coolant Environments on the Fatigue Life of Reactor Materials,"
dated February 2007.
4 ADAMS Accession No. ML16112A079.
5 ADAMS Accession Nos. ML16270A447, ML17054D480, and ML17136A362, respectively.
6 ADAMS Accession Nos. ML16242A008 and ML16364A279, respectively.
The NRC staff has completed its review of FENOC's submittals in response to DBNPS license renewal Commitment No. 42 and did not identify any issues. FENOC provided an evaluation which considered each of the elements described in the commitment. Therefore, the actions required by DBNPS license renewal Commitment No. 42 have been completed and CAC No. MF9704 is closed. If you have any questions regarding this request please contact me at (301) 415-1380.
