Dear.Mr.-Tiernan:
SUBJECT:
CALVERT CLIFFS UNITS 1 AND 2 SCHEDULE FOR' IMPLEMENTATION OF THE
' ATWS RULE.
The purpose;of this ~1etter is to provide youtinformation concerning-imple-
. mentation schedules for compliance with the requirements of the ATWS rule
The specific requirements arellisted 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 thefFederal Register on June 26, 1984.
Quality.
F
- Assurance (QA). guidance for-non-safety related ATWS equipment was issued by.
Generic Letter.(GL) 85-06 dated April 16,',1985. 'Therefore, plant specific Eschedules 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 meetingLthe 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,sti11' 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, iinterpretation 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 1
to a rushed effort-forced by schedular constraints, the NRC has decided to F
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 outagelafter 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.
