! ABSTRACT (Limitto1400 spaces, i.e., approximately fifteen single-space typewritten lines) (16)  !

On August 2, 1993, at approximately 1900, during a review of Technical Specification (TS) shift surveillances, it was determined that some portions of a shiftly surveillance i had not been performed. This shiftly surveillance had been successfully performed on l 4

August 1 at 2105, and on August 2 at 2030, with all systems found OPERABLE. Therefore, I

, all systems were, in fact, OPERABLE during this period and there was no safety I significance to this event.

SCE Operations procedures explicitly require that the entire surveillance procedure is  ;

to be used, and any inapplicable steps marked 'N/A". Contrary to this requirement, the operator failed to verify that the procedure copy used to perf onn the surveillance was complete., resulting in only 2 of 22 items being surveilled. Further, the normal review and approval of this procedure by the Control Operator and Control Room Supervisor failed to identify the incomplete surveillance.

The root cause of this event was cognizant personnel error on the part of: (1) the operator (utility, licensed) who perfonned this surveillance; and, (2) the two supervisors (utility, licensed) who had oversight responsibilities over the operator, and who reviewed and approved the incomplete surveillance.

As corrective action, the three plant operators involved have been counselled regarding the use of procedures. This event is also being reviewed by all plant operators.

A review of previous LER's did not reveal any similar events.
