Docket No.: 50-313 March 10, 1987 D. b Mr. Gene Campbell Vice President, Nuclear Operations Arkansas Power and Light Company P.O. Box 551 Little Rock, Arkansas 72203

SUBJECT:

ARKANSAS NUCLEAR ONE, UNIT 1 SCHEDULE FOR IMPLEMENTATION OF THE ATWS RULE The purpose of this letter is to provide you information concerning implementation 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 Recister on June 26, 1984. Quality Assurance (0A) guidance for non-safety relatec 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 OA guidance).

Many utilities responded by stating that final schedules for meetiro the require-ments 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 supplementary information published with the rule, and the review of generic ATWS desions 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 NPC 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 cutage 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.
