If a channel is determined to be inoperable, resulting in one less than the total number of. channels being operable, power operation may continue if the following conditions are met:

1.

' The minimum number of operable channels is still-satisfied..

2.

The affected channel is placed in trip within I hour.

Declare the associated standby emergency _ power _ supply inoperable for the affected bus. The applicable Limiting Condition for Operation-(LCO) shall;be. entered. Separate LCOs may_ be entered for the Degraded Voltage and Loss of.

Voltage functions.

Both switches must-be activated simultaneously.

'Use the 3/ bus specification for each A05 and A06 bus that has been modified to the 2 out of 3 logic for the loss-of voltage protection function.

in the reactor coolant system and the calculated saturation temperature. As a backup, the Plant Process Computer System (PPCS) displays subcooling margin by both addressable point and on the Safety Assessment System (SAS). A second backup display of subcooling information is available on seismically qualified plasma displays which receive input signals from seismically qualified multi-plexing equipment.

Control board indiN tions and a saturation curve can be used j

if failure of all direct subcooling indications occurs.
