Must actuate two switches simultaneously.
When primary pressure is less than 2000 psig, channels may be blocked.
When primary temperature is less than 547*F, channels may be blocked.
In this case the 2/3 high steam flow is already in the trip mode.
(a) During testing and maintenance of one channel, may be reduced to 1/bus.
(b) During testing and maintenance of one channel, may be reduced to 0/bus.
(c) The reactor may remain critical below the power operating conditions with this feature inhibited for the purpose of starting reactor coolant pumps.
