The TRIP: ACTUATING DEVICE OPERATIONAL TEST shall independently verify

.the OPERABILITY of the undervoltage and shunt trip circuits for the Manual Reactor Trip Function.

(12) -

The TRIP ACTUATING DEVICE OPERATIONAL TEST shall independently verify the OPERABILITY of the undervoltage and shunt trip attachments of the Reactor Trip. Breakers.

(13) -

Prior to placing breaker in service,'a local manual shunt trip shall be performed.

(14) -

The automative undervoltage trip capability shall be verified operable.

(15) -

Overtemperature setpoint, overpower setpoint, and T,yg channels re-quire an 18 month channel calibration.

Calibration of the AT channels is required at the beginning of each cycle upon completion of the precision heat balanceccf Serv:fil:::c 4.2.3.5.

RCS loop AT values shall'be determined by precision heat balance measurements at the beginning of each cycle,in ::::::tien with Serv;ill;.7;e 4.2.3.5.
