Dear Mr. Baskin:
SUBJECT:
SCHEDULE FOR IMPLEMENTATION OF THE ATWS RULE SAN ONOFRE, UNIT 1 (TAC NO. 59138)
The purpose of this letter is to provide you information concerning implementa tion schedules for compliance with the requirements of the ATWS rule (10 CFR 50.62). The specific requirements are listed in paragraphs (c)(1) through (c)(5) of the rule. Paragraph (d) of the rule addresses implementation schedules.
The ATWS rule was published in the Federal Register on June 26, 1984. Quality Assurance (QA) guidance for non-safety related ATWS equipment was issued by Generic Letter (GL) 85-06 dated April 16, 1985. Therefore, plant specific schedules for meeting the requirements of the ATWS rule were required to be submitted to NRR by October 15, 1985 (180 days after issuance of the QA guidance). Many utilities responded by stating that final schedules for meeting the requirements of the rule could not be determined until the staff completed its reviews of generic ATWS designs. The generic reviews have either only recently been completed or are still ongoing. Delays incurred in preparation of the QA guidance, and the extensive time and effort required to resolve complex issues associated with the development of review criteria, interpretation of the supplementary information published with the rule, and the review of generic ATWS designs have all impacted utility schedules.
Because of the cumulative effect of these delays, and in recognition that a sound and thorough engineering approach to resolve ATWS concerns is preferred to a rushed effort forced by schedular constraints, the NRC will consider favorably requests to extend the schedule for implementation of the ATWS rule.
Pursuant to 10 CFR 50.62(d) the delays referred to above justify extending implementation of the ATWS rule requirements to no later than the third refueling outage after July 24, 1984. A request for a delay beyond the third outage will be handled on a case-by-case basis if it is presented in a timely fashion, and if it is adequately justified.

-2 By letter dated October 27, 1986, Southern California Edison (SCE) stated that the ATWS mitigation system (turbine trip) at San Onofre 1 would be installed during the Cycle X refueling outage pending NCR review and approval prior to the outage. Since the Cycle X outage is the second outage beginning since July 24, 1984, this schedule is clearly acceptable in accordance with the guidance given above.
However, please contact me if you find it necessary to change the implementation schedule for ATWS equipment at San Onofre 1 in accordance with the guidance provided above.
