IMPROVED EMERGENCY SHUTDOWN FOR NUCLEAR REACTORS

Patent · Wed Dec 11 00:00:00 EST 1963

OSTI ID:4105309

An emergency shutdown apparatus for a reactor comprises a control rod and a suspension means disposed above the reactor core. The suspension means includes a temperature-responsive substance by which the control rod is attached to the suspension means; the substance has an appreciable structural strength at normal ambient reactor temperatures but virtually no strength at abnormal reactor temperatures, causing the control rod to fall into the core. Several embodiments of the shutdown apparatus are described. (D.L.C.)
