Abstract
The fuel temperature coefficient of reactivity is an important parameter in the evaluation of transients in light water reactors. The fuel temperature coefficient of an infinite lattice, often used in pin-cell calculations, is not a correct measure for the fuel temperature effect in such a lattice. We present a somewhat different definition of the fuel temperature coefficient of reactivity. This definition gives a more correct measure for the fuel temperature effect. Some calculations on lattices which are characteristic for a PWR show its accuracy. The newly defined fuel temperature coefficient is much less dependent on the fuel enrichment and the {sup 10}B-concentration. The fuel temperature coefficient is analysed by calculating the different components constituting this coefficient. (orig.)
