Patent · Wed Jul 24 04:00:00 EDT 1957

OSTI ID:4804382

A nuclear reactor control device is disclosed which releases a neutron absorbing gas in the event the reactor flux exceeds a predetermined value. The device consists of a stainless steel or aluminum can containing a cadmiumplated high-pressure chamber, a low-pressure chamber, and a normally sealed passage connecting the two chambers. A heating element responslve to neutron flux is so arranged that when the flux becomes excessive, the temperature of the heating element becomes sufficient to unseal the passage and release a neutron absorbing gas such as boron trifluoride (BF/sub 3/) enriched in B/sub 10/
