IMPROVEMENTS TO NUCLEAR REACTORS

Patent ·
OSTI ID:4839561
A device is offered for shutting down a nuclear reactor and to keep it in this state. For instance to shut down a reactor installed on a ship in the event of strong rolling or even capsizing, means are provided to shut down the reactor by insertion of movable control rods and to keep these rods in the shut- down position, even in opposition to the force of gravity. Each control rod may suitably be forced into the reactor by a pressure fluid coacting with a plunger sliding in a cylinder forming the chute for the control rod. When a control rod reaches the shut-down position, a plug connected to it butts against a stop and controls the action of radially working locking means. (NPO)
