ABSTRACT:
A system is provided which prevents the operation of a nuclear reactor in a region of a prohibited reactor power distribution. The method of operation includes inhibiting the insertion of control rods into the reactor on the basis of a power dependent control rod insertion limit and further overriding the control of the reactor by rapidly reducing reactor power when reactor power increases to a reactor power which exceeds by a predetermined margin the limit set by the power dependent control rod insertion limit.
