Southern California Edison Company
P. 0. Box 800

Rosemead, California 92770
Attention: Mr. Kenneth P. Baskin, Vice President
Nuclear Engineering, Safety, and Licensing
Gentlemen:
This refers to the routine inspection conducted by Messrs. F. R. Huey,
J. E. Tatum, and A. L. Hon of this office during the period of April 10
through May 21, 1988 of activities authorized by NRC License Nos. DPR-13,
NPF-10 and NPF-15 and to the discussion of our findings held by the inspectors
with Mr. C. B. McCarthy and other members of the Southern California Edison
staff at the conclusion of the inspection.
Areas examined-during this inspection are described in the enclosed inspection
report. Within these areas, the inspection consisted of selective
Oexaminations of procedures and representative records, interviews with
personnel, and .observations by the inspectors.
No violations of NRC requirements were identified within the scope of this
inspection.
Your staff's failure to monitor fundamental parameters and to establish
appropriate operability criteria for the emergency chillers (discussed in
paragraph 2b of this report) is of concern to the NRC.
The lack of a timely
assessment of chiller operability on April 2, 1988, when refrigerant level was
found to be low, is also of concern. Your attention is warranted to ensure
that these concerns are adequately addressed. In this regard, please provide
a written response to discuss the actions that you are taking to resolve these
concerns.
We understand that four fire suppression system actuations have occurred in
Unit 3 cable riser rooms since April, 1988. We are interested in the actions
you are taking to evaluate and determine the root cause of these occurrences,
including the communications, technical support, and possible long-term
degradation aspects involved. We will evaluate these as part of our ongoing
inspection program.
In accordance with 10 CFR 2.790(a), a copy of this letter, the enclosure, and
your response will be placed in the NRC Public Document Room.

discuss them with you.
