SUBJECT:

MILLSTONE UNIT 2 SCHEDULE FOR IMPLEMENTATION OF THE ATWS RULE The purpose of this letter is to provide you information concerning imple-mentation 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 implementa-tion 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 has decided to extend the deadline for implementation of the ATWS rule. The revised schedule allows you to delay implementation of 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 can be adequately justified.
