Three kinetic (source-jerk, rod-drop, and pulsed source) methods of measuring reactivity in the subcritical state are discussed from both the theoretical and experimental points of view. The kinetic, static, and dynamic role played by the three reactivities is demonstrated by the general transport theory. After reducing this to the multigroup model, additional important properties of delayed and prompt neutron distributions are shown. Using two group time dependent theory, numerical examples are given to show the importance of these properties in heavy water reactors. With the help of the theoretical results, modification of the source-jerk and rod-drop techniques, aimed at lessening perturbing effects, are discussed. These modified experimental methods were successfully checked in the swimming-pool reactor SAPHIR and the heavy-water reactor DIORIT in Wurenlingen. Some of the experiments are reported. (auth)
