A. Failed components:

None.

B. Previous LERs on similar events:

The following LERs involved missed surveillances caused by incorrect updating of the PMTS:

1-84-037 -

Surveillance on Containment Fan Cooler Unit 1-2 not performed within Technical Specification required interval.

1-85-034 -

, Technical Specification required surveillance not '

completed due to computer data entry error. ~

1-86-001-01 -

Reactor coolant system temperature and containment pressure instrumentation surveillances missed due to inadequate understanding of the PMTS updating requirements.

2-86-015 -

Missed surveillance on a radiation monitor due to the PMTS system file being updated in error.

If the corrective actions in the above LERs had been instituted prior to the event reported in LER 2-85-027, these corrective actions could have prevented the event in LER 2-85-027. The event in LER 2-85-027 occurred before the discovery dates of the events i in LER 1-84-037, LER 1-86-001-01 and LER 2-86-015. Although the discovery date of LER 1-85-034 was approximately three weeks prior to the event in LER 2-85-027, there had not yet been sufficient time to fully implement the corrective action of LER l-85-034.
