Attention: Mr. Harold B. Ray, Senior Vice President, Power Systems
SUBJECT: NRC INSPECTION REPORT NOS. 50-206, 361, 362/93-26
This refers to the routine inspection conducted by C. W. Caldwell,
J. J. Russell, D. L. Solorio, and D. F. Kirsch, of this office, and C. M.
Regan, of the Office of Nuclear Reactor Regulation, on July 29 through
September 1, 1993, 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
OMr.
R. W. Krieger and other members of the Southern California Edison Company
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
examinations 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. However, we were concerned that NRC inspectors identified a
significant hydraulic oil leak on a Unit 2 main feedwater isolation valve that
had not been identified by your staff. If left uncorrected, this leak had the
potential to cause a Unit 2 reactor trip.
Further management attention is
warranted to highten your staff's attention to equipment irregularities as
they conduct plant tours.
We also consider that your efforts in the area of risk management to be a
significant strength. Your efforts to put into place an on-line "risk
monitor" is indicative of your innovative actions and industry leadership in
this area.
We urge you to continue your extensive use of risk assessment
during power operations and refueling outages.
