RANCHO SECO NUCl. EAR GENERATING STATION SPDS QUARTERLN PERFORMANCE REPORT JANUARY 1 - MARCH 31, 1989 SPDS Reliability l

l The B channel of the SPDS operated continuously throughout the quarter with 100% availability.

l The A channel was inoperable for two five minute periods on March 23, 1989.

These outages occurred from 13:20 to 13:25 and 13:45 to 13:50, respectively.

The outages were caused by an error lockup in the Aratec Central Control Unit #1 (CCb). Upon reset of CCU #1, operation returned to normal on both occasions. During both periods the B channel was fully operational.

Because all plant parameters are available on both the A and B channels, no signal information was lost. It can therefore be stated that SPDS was 100%

available. The only effect was the loss of duplicate displays. Considering the ten minutes of downtime, the availability of the A channel was 99.992% for this report period.

SPDS availability has been 99.998% for the four periods report (including this quarter for A channel).

SPDS Performance The SPDS performance is reflected by the attached comparison between analog meters and the SPDS computer driven displays.
