Abstract

PURPOSE: To control the reactor safely and quickly by comparing the output of reactor with the number of non-operated by-pass valves, which is decided by the logic circuit.
CONSTITUTION: The controller 50 of the control unit 17 in which a signal 10B is fed from the detecting circuit 10 emits an exciting signal 47A which excites the solenoid 47, which makes the quickly operated electromagnetic valve 45 operate through the axis 46. The quickly operated electromagnetic valve 45 controls the position of disc 42 in the cylinder 41 fixed to the valve rod 40 of by-pass valve 7, the said operation makes the by-pass valve 7 open. When the by-pass valve is faulty, it can be quickly detected to make the reactor take a protective action by means of a control signal.
