J. L. Crews, Director, Division of Resident, Reactor Project and Engineering Inspection, IE:RV FROM:
A. E. Chaffee, Regional Reactor Inspector, San Onofre Unit 1
SUBJECT:
(SALP) ITEM:
SURVEILLANCE REVIEW OF SAN ONOFRE UNIT 1 As a result of concerns addressed in the SALP Review Board conducted in 1980, a preliminary review was done of San Onofre Unit 1 Technical Specifications (Amendment 56) versus the Westinghouse Standard Technical Specifications (NUREG 0452, Rev. 3).
This review was focused on surveillance requirements.
It revealed a large number (101) of surveillance items which are not covered by Songs 1 Technical Specifications. Many of these items appear to be significant. Enclosure 1 is forwarded for your review and action.

-7 Note:
Of approximately 150 surveillance requirements in standard Technical Specification which are applicable to San Onofre Unit 1, San Onofre has only 49. This means Songs is lacking approximately 67 percent of the applicable surveillance requirements in the standard technical specifications.
Note:
Technical Specification beginning with "4" are surveillance requirements. All others are LCOs.
- These items are of particular concern.
