IMPROVEMENTS IN OR RELATING TO MEANS FOR SHUTTING DOWN NUCLEAR REACTORS

Patent ·
OSTI ID:4111839
A secondary shut-down system that will operate in the event of pressure- vessel rupture is designed comprising a magazine of boron-steel balls positioned above a tube in the reactor core and held in position by the magnetic field of energized coils. Upon coil deenergization, the balls fall into the tube to operate as a shut-down rod. When it is desired to restore the system to its inoperative state, the tube containing the balls is moved up with a grab and the balls placed in the magazine. Drawings are included. (D.L.C.)
