OSTI ID:4283816
An analytical study was made of the transient behavior of low-power reactors. It is shown how the effect of six delayed neutron groups can be analyzed by means of an approximation which makes use of only one or two equivalent groups of delayed neutrons. Reactor kinetics is reviewed under the assumption that there is only one equivalent group of delayed neutrons. The transient response is determined for a pulsed variation, a linear variation, an exponential variation, and a 1/t variation in the reactivity. An indication is given of a method of extending the results obtained to the case of six groups of delayed neutrons. The case of a reactor in which the reactivity undergoes periodic oscillations is considered. It is shown that the neutron flux increases exponentially when the reactivity is a quasi-harmonic function of zero mean. (J.S.R.)
