Attention:
Mr. Harold B. Ray, Vice President
Nuclear Engineering, Safety, and Licensing
Gentlemen:
Subject:
Systematic Assessment of Licensee Performance (SALP)
The NRC Systematic Assessment of Licensee Performance (SALP) Board has
completed its periodic evaluation of the performance of your San Onofre
Nuclear Generating Station during the period October 1, 1988 through
January 31, 1990.
The performance of San Onofre was evaluated in the functional areas of plant
operations, radiological controls, maintenance/surveillance, emergency
preparedness, security, engineering/technical support, and safety
assessment/quality verification. The criteria used in conducting this
assessment and the SALP Board's evaluation of your performance in these
functional areas are contained in the enclosed SALP report.
Based upon discussions with your staff, a management meeting to discuss the
results of the SALP Board's assessment has been scheduled for April 25, 1990,
at the San Onofre site. Arrangements for the management meeting will be
discussed further with your staff in the near future.
Overall, the SALP Board found your performance to be acceptable and directed
toward safe facility operation. Good performance was noted to have continued
in the radiological controls, emergency preparedness, and security functional
areas, and maintenance/surveillance was also considered to be an 'area of
strength. The Board also recognized improved performance in the areas of
engineering/technical support, and safety assessment/quality verification as a
result of your attention and initiatives in these areas.
However, several concerns were identified by the NRC during this assessment
period. A concern common to several functional areas, particularly in plant
operations and maintenance, was the need for additional attention to details
during the performance of routine activities. In addition, weaknesses were
identified that were specific to three functional areas, as follows:
-
Operations -- instances of inappropriate application of Technical
Specifications requirements, and several examples of operational errors
during fundamental plant evolutions.

Engineering/Technical Support --
inadequate translation of design bases
into component setpoints, lack of formal calculations for key design
parameters related to some of the electrical distribution systems, and
problems with design change outputs that resulted in plant events.
-
Safety Assessment/Quality Verification -- problems with implementation of
the corrective action program, inadequate safety evaluations, and poor or
untimely licensing submittals.
Overall, however, SCE management recognized a need for improvement in these
areas and initiated corrective actions during the latter part of the SALP
period.
A management summary of this assessment is provided in Section II of the
enclosed report. Perceived strengths and weaknesses and Board recommendations
are discussed in Section IV, Performance Analysis.
In that no functional area was assessed as Category 3, a written response to
the enclosed initial SALP report is not required. Should you wish to submit
comments on the report, they should be provided within 30 days after the April
25, 1990 meeting.
In accordance with Section 2.790 of the NRC's "Rules of Practice," Part 2,
Title 10, Code of Federal Regulations, a copy of this letter and the enclosed
.SALP
report will be placed in the NRC's Public Document Room, as well as any
comments you may wish to submit to the NRC regarding the content of the SALP
report.
The NRC's Office for Analysis and Evaluation of Operational Data performed an
assessment of licensee event reports submitted for San Onofre. This assess
ment was provided as an input to the SALP process; a copy is therefore
provided as Attachment 1 to the enclosed report.
Should you have any questions concerning the SALP report, we will be pleased
to discuss them with you.
Since ely,
J. B. Martin
Regional Administrator
