FIELD: physics, atomic power.
SUBSTANCE: present invention relates to an accelerator-driven subcritical breeding reactor. The reactor is operated with a neutron multiplication coefficient as large as possible in order to require a small input power from the accelerator, with reduction of its dimensions and complexity of the accelerator. The beam-generated fission neutron yield becomes comparable to the fraction of delayed neutrons from the fissioned elements. This can be used to ensure an accurate determination of reactivity during operation. Resulting changes can be adjusted using control rods (111), which are controlled using neutron absorbers (112) and/or by varying of proton current. In addition, conditions of the present invention allow continuous control of temperature change during operation through a heat exchanger (103).
EFFECT: preventing a subcritical device from approaching too close to a critical condition while maintaining the neutron multiplication coefficient within acceptable limits.
