Control of reactor pulses by external neutron injection

It is shown that it is possible to regulate the energy of each pulse of a p owerful pulsed periodic reactor using an injector of relatively low power. The target in the reactor core generates the neutron pulses forced by the i njector. The correlations for determination of the moment of injection are obtained. The equation connecting the mean reactor power, the intensity int egral of the target and the scatter multiplicity of the pulse energy withou t injection is obtained. In addition to its function as a regulator, the in jector plays the role of an auxiliary emergency unit. It is shown that usin g an injector provides a regime in which the reactor can generate power pul ses in the form of periodic packets. (C) 2001 Elsevier Science Ltd. All rig hts reserved.
