, TABLE NOTATION (11) - 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.
