Fuel temperature coefficient of reactivity — is the change in reactivity of the nuclear fuel per degree change in the fuel temperature. The coefficient quantifies the amount of neutrons that the nuclear fuel (uranium 238) absorbs from the fission process as the fuel temperature increases.… … Wikipedia
Temperature coefficient — The temperature coefficient is the relative change of a physical property when the temperature is changed by 1 K. In the following formula, let R be the physical property to be measured and T be the temperature at which the property is… … Wikipedia
