(under subclass 327) Subject matter wherein the control component is moveable with respect to the reactor core and the means for affecting movement of the control component is actuated by or is responsive to, an abnormal reactor operating condition (e.g., abnormal increase in temperature or abnormal increase in neutron flux).
(1) Note. The abnormal increase in temperature or neutron flux may cause the melting of a solder plug which will then allow the control component to move relative to the reactor core into a position which will cause a decrease in the reactivity of the reactor core.
