Temperature changes occur more or less independently in the fuel, the heat transport system, and the moderator. There is a temperature coefficient of reactivity associated with each of these. The "self-regulating" characteristics... require the overall temperature coefficient of a reactor to be negative, but changes in fuel temperature are the most important in determining the overall coefficient. 1, record 3, English, - self%2Dregulating
