Periodic change in neutron density, when the reactor is in the subcritical initial state, is caused by sinusoidal change of the effective multiplication factor with a definite amplitude and frequency. The mean value of neutron density, depending on amplitude, frequency, and initial depth, either remains constant, rises to a definite value, or increases infinitely with the velocity, depending on the frequency and amplitude of the sinusoidal change of the effective multiplication factor. Analysis of the behavior of neutron density at different laws of the effective multiplication factor change shows that the sinusoidal change combined with a simultaneous increase of the effective multiplication factor allows the reactor in subcritical state with an arbitrary depth of subcriticality to be brought up to the required level of neutron density; in this case the reactor is in subcritical state with respect to a non- periodic component of reactivity.
