Abstract
An automatically scramming nuclear reactor system. One embodiment comprises a control element moveable relative to a core of the reactor between an upper position and a lower position. An electrically-resistive element is positioned in thermal contact with the core, and has a variable resistance that changes in response to a change in temperature of the core. A release system is positioned adjacent the core. The release system is operatively associated with the electrically-resistive element and holds the control element in the upper position during a normal operating condition of the nuclear reactor system. The release system releases the control element when the temperature of the core changes from a safe operating temperature so that the control element automatically falls under the action of gravity to the lower position in the core.
