Dear Mr. Utley:
OGC-B E. Jordan
SUBJECT:
FAST NEUTRON FLUENCE FOR THE FRACTURE TOUGHNESS REQUIREMENTS FOR PROTECTION AGAINST PRESSURIZED THERMAL SHOCK EVENTS, 10 CFR 50.61 (TAC No. 59977)
H. B. ROBINSON STEAM ELECTRIC PLANT, NO. 2
References:
- 1. Letter from S. R. Zimmerman, Carolina Power and Light Company to L. Rubenstein NRC, "Pressurized Thermal Shock, Correction to Response to Final Rule 10 CFR 50.61," dated February 4, 1986 (Serial No. NLS-86-045)
- 2. Letter from S. R. Zimmerman, Carolina Power and Light Company to NRC, "Resolution of Reactor Vessel Materials Revised Pressurized Therman Shock Response," dated January 16, 1987 By letters dated February 4, 1986, and January 16, 1987, you submitted revised information on the material properties and the fast neutron fluence of the reactor pressure vessel in compliance with the requirements of 10 CFR 50.61 (Reference 1, 2).
We have reviewed the material properties and chemical composition and found them to be acceptable. The Safety Evaluation is included for your information as Enclosure 1. We have also reviewed the fast neutron fluence on the inside surface of the pressure vessel in view of the material properties. We find that the H. B. Robinson Steam Electric Plant Unit No. 2 pressure vessel meets the toughness requirements of 10 CFR 50.61 for operation to the end of the current license, provided that future core loadings continue to provide sufficient flux reduction so that the 10 CFR 50.61 acceptance criteria are met. The Safety Evaluation is included for your information as Enclosure 2. This review was carried out, in part, by our contractor, Brookhaven National Laboratory.
We request that you submit periodic future reevaluations of the RT and the comparisons with the predictions of References 1 and 2. The eVfuations and comparisons could be submitted along with the pressure temperature operating limits that are required by 10 CFR 50, Appendix G.
This request is covered by Office of Management and Budget Clearance Number 3150-0011 which expired September 30, 1989. Comments on burden and duplication may be directed to the Office of Management and Budget, Room 3208, New Executive Office Building, Washington, D. C. 20503.
