Docket No. 50-206
Southern California Edison Company
P. 0. Box 800
2244 Walnut Grove Avenue
Rosemead, California 92770
Attention: Mr. Kenneth P. Baskin, Vice President
Nuclear Engineering, Safety, and Licensing
Gentlemen:
This refers to the meeting held with you, Mr. C. B. McCarthy, Jr., and other
members of the SCE staff in the Region V office on March 24, 1988. The
subjects discussed are summarized in the enclosed meeting report. A copy of
the meeting agenda is included as Attachment 1 to the report.
The primary purpose of this meeting was to discuss recently identified
problems involving the environmental qualification (EQ) of safety related
equipment in San Onofre Unit 1. The meeting also included discussion of other
issues related to the accomplishment of engineering and technical work, as
well as your current activities associated with the transfer of Unit 1 spent
fuel to Units 2 and 3.
The following topics were given special emphasis in our discussions during
this meeting:
1. The recently identified EQ problems were discussed, along with the
corrective actions you plan to complete before Unit 1 restart. However,
the NRC representatives present expressed concern regarding SCE's plan to
restart the unit before completion of the 10 CFR 50.49(b)(2) review of
electrical interactions, as discussed in Mr. Medford's March 11, 1988
letter. In that regard, you should submit for the NRC's review your
rationale for proceeding with restart in the absence of a clear knowledge
as to Unit 1's state of compliance with 10 CFR 50.49(b)(2). In
discussions subsequent to our meeting, it has been determined that NRR
will assume the lead role for the NRC's evaluation of current Unit 1 EQ
issues, particularly your justification for restart before the (b)(2)
review is completed.
2. We discussed your plans to transfer Unit 1 spent fuel to Units 2/3,
particularly the significant disagreement which still exists between SCE
and the NRC regarding whether this can be done without amendment of the
Unit 1 license. In view of SCE's plan to ship fuel as soon as one week
after the date of our meeting, I was disturbed that this issue had not
been previously brought to the attention of higher levels of NRC
management. It is important that your 10 CFR 50.59 review be completed
promptly and provided for NRC review.

3. During a December 15, 1987 meeting with SCE management, we discussed
the quality of technical and engineering work performed at San Onofre and
the role of the various safety oversight groups (QA/QC, Nuclear Safety
Group, Independent Safety Engineering Group and Onsite Review Committee)
in assessing your staff's performance and identifying problems in
technical and engineering areas. The EQ deficiencies identified to date
indicate a major weakness in the control of associated engineering and
technical work in this area and, in view of the fact that these problems
have existed for an extended period of time, appear to question the
effective involvement of your quality oversight groups in this area.
4. Your plans to perform a safety system functional inspection (SSFI) of the
safety injection and charging systems were discussed, as addressed in Mr.
H. E. Morgan's letter dated March 17, 1988. It was noted that inspection
of selected components, including the safety injection switchover valves
(HV-851 through -854) in one train, will be completed before Unit 1
restart.
We anticipate further discussion of items 3 and 4 above during our next
management meeting, presently anticipated during the latter part of April
1988.
In accordance with 10 CFR 2.790(a), a copy of this letter and the enclosure
will be placed in the NRC Public Document Room.
.
Should you have any questions concerning this letter or the issues discussed
in the enclosed report, we will be glad to discuss them with you.
Sincerely,
J. B. Martin
Regional Administrator
