The RBMK (Russian: реа́ктор большо́й мо́щности кана́льный, РБМК; reaktor bolshoy moshchnosti kanalnyy, "high-power channel-type reactor") is a class of graphite-moderated nuclear power reactor designed and built by the Soviet Union.
A bigger problem was the design of the RBMK control rods, each of which had a graphite neutron moderator section attached to its end to boost reactor output by displacing water when the control rod section had been fully withdrawn from the reactor. That is, when a control rod was at maximum extraction, a neutron-moderating graphite extension ...
The plant has four nuclear reactors of the RBMK-1000 type, all of which are first generation units similar to that of Kursk and Chernobyl units 1 and 2. Each unit has a separate reactor building but the turbine hall is shared between 2 reactors. [2] In 2008, construction started on Leningrad II with 2 VVER-1200 type reactors. They will ...
Reactors No. 3 and 4 were second-generation units, whereas No. 1 and 2 were first-generation units, like those in operation at the Kursk power plant. Second-generation RBMK designs were fitted with a more secure containment structure, visible in photos of the facility. [15]
The Chernobyl disaster was a catastrophic nuclear disaster that occurred in the early hours of 26 April 1986, at the Chernobyl Nuclear Power Plant in Soviet Ukraine.The accident occurred when Reactor Number 4 exploded and destroyed most of the reactor building, spreading debris and radioactive material across the surrounding area, and over the following days and weeks, most of mainland Europe ...
Some of these RBMK reactors were originally to be shut down but have instead been given life extensions and uprated in output by about 5%. Critics say that these reactors are of an "inherently unsafe design", which cannot be improved through upgrades and modernization, and some reactor parts are impossible to replace.
A: So the reactor is fueled, the reactor is closed, bolted shut. Control rods are slowly being pulled out. The control rods absorb neutrons without undergoing any nuclear reactions.
