WebIn both HTR designs the large graphite components act as neutron moderator and reflector as well as providing mechanical support to the active core. During reactor operation the graphite components of the core are subjected to complex stress states. Consequently, core designers need a suitable theory of failure. WebThe RBMK reactor is graphite-moderated, so a core of solid graphite is responsible for slowing down fast neutrons in the reactor core. In fact, the name RBMK is a Russian acronym for "High-powered channel-type …
