Control of reactor pulses by external neutron injection

It is shown that it is possible to regulate the energy of each pulse of a powerful pulsed periodic reactor using an injector of relatively low power. The target in the reactor core generates the neutron pulses forced by the injector. The correlations for determination of the moment of injection are obtained. The equation connecting the mean reactor power, the intensity integral of the target and the scatter multiplicity of the pulse energy without injection is obtained. In addition to its function as a regulator, the injector plays the role of an auxiliary emergency unit. It is shown that using an injector provides a regime in which the reactor can generate power pulses in the form of periodic packets.
