= Fuel temperature coefficient of reactivity
{wiki=Fuel_temperature_coefficient_of_reactivity}
The fuel temperature coefficient of reactivity is a parameter used in nuclear reactor physics to describe how the reactivity of a nuclear reactor changes in response to changes in the temperature of the nuclear fuel. Reactivity is a measure of the deviation from criticality in a nuclear reactor; it indicates whether the reactor is in a subcritical, critical, or supercritical state. The temperature of the fuel can affect both the neutron absorption characteristics and the fission process, which in turn influences the reactivity.
