Resumo

While the primary purpose of the BIR and BIGR reactors is to generate neutron and gamma irradiation pulses, they were also used regularly to conduct experiments aimed at enhancing the parameters of radiation of pulsed reactors, making them safer, and examining various topics in neutron physics. The present review addresses the following issues: long-term performance of BIR and BIGR in the mode of self-adjustment of power; generation of fission pulses when the rod passes through the core; coupled systems (BIR + a subcritical assembly); experiments with ultracold neutrons at the BIGR reactor; and fast-acting emergency protection and the pulse delay time in the BIR reactor with a weak neutron source in the core.
