RBMK reactor fuel was used in Soviet-designed and built RBMK-type reactors. This is a major difference: whereas the loss of water in a normal BWR would stop the reaction, in the RBMK, reactor power will increase if water is lost. The RBMK reactor uses graphite as a moderator, whereas water in the reactor acts as what’s known as a ‘poison’ – capturing neutrons much like control rods and slowing the fission reaction.

The RBMK reactor became unstable as xenon gas-a neutron absorber-formed in the core. The RBMK (Russian Acronym for "Channelized Large Power Reactor") is a graphite-moderated boiling water channel-type reactor with the principle of electricity generation the same as for boiling water reactors (BWRs). It is a rather unusual design as it uses graphite as its moderator, and was designed for plutonium production—but was also used extensively for electrical generation.The combination of graphite as a moderator and light water as coolant is unique to this reactor as no other reactors in the world use both. 0000002178 00000 n In response to this proposal, IEI and Pacific Northwest Laboratory (PNL) jointly provided funding to send Dr. Dennis W. Wester on a fact-finding mission to Novosibirsk, The objective of this joint U.S./Russian study was to develop a safe, technically feasible, economically acceptable strategy for decommissioning Leningrad Nuclear Power Plant (LNPP) Unit No. The graphite-moderated reactors were of the Soviet RBMK type.

Specifically, it was a Soviet-created graphite-moderated channel tube reactor, which in Russian takes the acronym RBMK. It has a graphite block structure as the moderator that slows down the neutrons produced by fission. Water in the reactor serves both as a coolant and a moderator which is an important safety feature. CONTROL METHODS.

Leningrad II-2 will replace Leningrad-2, an RBMK reactor that has been in operation for 45 years. There was a well known design flaw with the RBMK type reactors that meant that after a SCRAM the reactor would be without flowing cooling water for up to 75 seconds, during which time enough heat could build up in the reactor core to cause a catastrophic failure.
