Some later RBMK designs did include control rods on electromagnetic grapples, thus controlling the reaction speed and, if necessary, stopping the reaction completely. The RBMK reactor at Chernobyl, however, had manual clutch control rods. All RBMK reactors underwent significant changes following the Chernobyl disaster.
Chernobyl Nuclear Power Plant's original Soviet plan consisted of 12 units, and that units 5 and 6 were phase three of the plan. At the time, only two phases were complete, reactors 1, 2, 3 and 4. Both units were intended to be RBMK-1000 and would generate approximately 1,000 megawatts each, and also be supported by two cooling towers located ...
RBMK reactors, such as the reactors at Chernobyl, had a dangerously high positive void coefficient. This allowed the reactor to run on unenriched uranium and to require no heavy water, saving costs; RBMKs were also capable of producing weapons-grade plutonium, unlike the other main Soviet design, the VVER.

The Chernobyl nuclear power plant is located next to the Pripyat River, which feeds into the Dnieper reservoir system, one of the largest surface water systems in Europe, which at the time supplied water to Kiev's 2.4 million residents, and was still in spring flood when the accident occurred.
However, in light of the Chernobyl incident in 1986, many of these reactors were either cancelled, or left unfinished. Some of these reactors had significant infrastructure already in place in preparation for construction but were halted as the reactors were seen as very unsafe.
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 ...
Light water graphite reactors were built only in the USSR. RBMK designs used secondary containment-like structures, but the reactor's top plate was a part of the protective structure. During the Chernobyl accident in 1986 the plate suffered a pressure beyond the predicted limits and lifted up.
