10 l 2 l l pressure switch PS-1-1001-88C tripped at 2.03 psig.

This is 0.03 psig higher than l

g g,3, g the Technical Specification limit in Table 3.1-3 The consequences were minimal l

g because protection was provided by the other pressure switches in the one-out-l lO is t I of-two-twice logic, which were all properly calibrated.

The switches initiate a

The pressure switch I

i i l

was recalibrated and functionally tested. These switches have been found to have '

I j, g 7, l

some setpoint dri f ting. The f requency of any one switch constantly dri f ting high I

g,;3)l is minimal therefore no other corrective ac+. ion is necessary at this time.
