Subject:
Docket No. 50-206 Final Acceptance Criteria for the Thermal Shield Monitoring Program San Onofre Nuclear Generating Station Unit 1 The enclosure to this letter provides the final acceptance criteria for the reactor vessel thermal shield monitoring program in accordance with Provisional Operating License DPR-13 License Condition 3.M, "Cycle X Thermal Shield Monitoring Program."
Interim acceptance criteria were previously provided to the NRC by letter dated September 6, 1989. On October 4, 1989 SCE received a telecopy of the staff's Safety Evaluation of the interim acceptance criteria which included six recommendations to be incorporated in the final acceptance criteria. This Safety Evaluation was later transmitted to us by letter dated November 3, 1989. These recommendations have been included in the final criteria.
The thermal shield monitoring program in conjunction with the enclosed acceptance criteria will provide sufficient indication of the thermal shield condition to assure the safe operation of Unit 1.
If you have any questions or desire further information, please contact me.
Very truly yours,
Enclosure:
