Subject:

Docket No. 50-206 San Onofre Nuclear Generating Station Unit I

Reference:

Letter, Robert Dietch, SCE, to H. R. Denton, NRC, dated June 10, 1983 The referenced letter provided information pertaining to SCE's plans for continuation of work at San Onofre Unit 1. It has come to our attention, however, that there are a number of typographical.errors on page 2 of that letter which may lead to some confusion. Therefore, please find enclosed a replacement page 2 which should replace the original in the referenced letter. This will assure more complete understanding of the continuing actions SCE will be taking with regards to San Onofre Unit 1.

We regret any misunderstanding this oversight may have caused.

Please contact me if you require additional information.

Very truly yours, R. W. Krieger Supervising Engineer San Onofre Unit 1 Licensing Enclosure A01 9306220004 830616 PDR ADOCK 05000206 P

Mr. H. R. Denton

-2 The purpose of this letter is to discuss the implementation of each of these plans as they relate to the resumption of power operation at San Onofre Unit 1. Specifically, the following actions will be taken:

1. work closely with the NRC to obtain concurrence on each of the plans,
2. continue to perform work (i.e., surveillance, maintenance and refurbishment) required to safely maintain the plant in cold
shutdown,
3. continue to work on the modifications which must be implemented this outage relating to Three Mile Island Category B Items as specified in Confirmatory Order dated March 14, 1983 and Fire Protection Appendix R modifications as specified in Supplement I to the Fire Protection Safety Evaluation Report dated February 4, 1981, with the exception of those associated with safe shutdown.
4. continue to work on the SEP., including the Integrated Assessment, in order to identify the necessary modifications which must be implemented, and
5. defer all other work which is not covered by Items 2, 3, and 4 above until such time as NRC concurrence is obtained on each of the plans.

Relative to Item 5 above, it will be necessary to work with the NRC to issue an exemption to defer the implementation of (1) Fire Protection Appendix R Safe Shutdown modifications required by 10 CFR 50.48, and (2) Environmental Qualification submittals and modifications required by 10 CFR 50.49, to coincide with the schedules agreed upon in the "Plan for Managing Plant Retrofit."

It has been determined that all other work covered by Item 5 above is (or will be) based on schedules negotiated with the NRC and these schedules will be renegotiated and agreed upon in the "Plan for Managing Plant Retrofit."

The actions discussed above will (1) assure that we can continue to safely maintain the plant in cold shutdown, and (2) establish a long-term integrated plant modification upgrade schedule that provides a greater benefit to improving plant safety and/or reliability while optimizing the use of SCE and NRC resources.

Based on recent NRC activities related to (1) Supplement I to NUREG-0737, (2) instrumentation for detection of inadequate core cooling, and (3) proposed rulemaking on safety goals and backfitting, the actions discussed above are consistent with the regulatory trend toward adopting a plan to establish realistic plant specific integrated schedules that take into account the unique aspects of the work at each plant.
