• In the companion paper(1) the author developed an analytical model for space-dependent boiling water reactor kinetics by method of conventional adiabatic approximation. In this paper some numerical simulations were performed for a sample boiling water reactor of 200MW(th), together with an analysis of its space-time behavior. The external perturbations applied to the reactor were: (1) A step increase in reactivity of 90 cents, (2) sinusoidal variations in reactivity with an amplitude of 10 cents, and (3) sinusoidal variation in vertical acceleration with an amplitude of 0.5g. Results of the simulation study indicate that space-dependence is significant when the reactor is undergoing a large transient, while for small disturbances the reactor behaves with little nuclear space-dependence. The latter fact agrees with experimental results on existing boiling water reactors.
