Abstract

PURPOSE: To prevent a generation of the pump.missile in primary coolant recirculation system, by such means that, when a flow quantity of the primary coolant, passing through the recirculating pump, is increased to above the set value, a breaking force be automatically applied to the rotary shaft of the above said pump.
CONSTITUTION: For recirculation of the primary coolant in the nuclear reactor pressure vessel 1, is provided a recirculating tubing 2, however, for instance, if caused a fault of broken point at the outlet side of a recirculating pump 3 in the tubing 2, the primary coolant in the vessel 1 passes an inlet valve 4 and the pump 3 to flow out at almost critical speed from the broken point 6. And when utilizing the fact of a rotary shaft of the pump 3 being rapidly accelerated rotational speed, a detection of the rotational speed is operated by a governor 7 installed to said rotary shaft, with a brake device 8 actuated, and the braking force is made to be automatically applied to the pump 3. In such constitution, when caused a damage in the recirculating piping, a failure of the pump.missile can be effectively prevented.
