In the absence of the required number of operable instrument channels in a single trip system, that system is to be tripped.
Contrary to the above, the reactor was operated at full power in the "run" mode with one of two Main Turbine Fast Closure sensing pressure switches in a trip system valved out and that trip system untripped from 0850 to 1850 on November 17, 1981.
