The FLNP Directorate is introducing the scientist to the reflecting system of the IBR-2 Pulsed Reactor.
The movable reflector is one of the most unique technical components of the reactor. Its task is to control the reactivity, that is, the conditions of the nuclear chain reaction, and to ensure the pulsed mode of operation of the facility.
The system consists of two parts: the main and additional movable reflectors. They rotate in opposite directions at different speeds. In their certain relative positions, a short power pulse occurs near the core, accompanied by an intense neutron emission.
