Technical data on RBMK-1500 reactor at Ignalina nuclear power plant – a decommissioned RBMK reactor. Chernobyl – A Canadian Perspective – A brochure describing nuclear reactors in general and the RBMK design in particular, focusing on the safety differences between them and CANDU reactors. Published by Atomic Energy of Canada Limited.
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 ...
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 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 ...
Eleven of Russia's reactors are of the RBMK 1000 type, similar to the one at Chernobyl Nuclear Power Plant. 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 ...
On the other hand, if a reactor is designed to operate with no voids at all, a large negative void coefficient may serve as a safety system. A loss of coolant in such a reactor decreases the thermal output, but of course heat that is generated is no longer removed, so the temperature could rise (if all other safety systems simultaneously failed).
The plant has four nuclear reactors of the RBMK-1000 type, Units 1 and 2 of which are first generation units similar to that of Kursk and Chernobyl units 1 and 2 and 3 and 4 are second generation similar to Chernobyl 3 and 4. Each unit has a separate reactor building but the turbine hall is shared between 2 reactors. [2]
Type of reactor: RBMK-1000 graphite moderated, 2nd generation reactor without containment: BWR-3 and BWR-4 reactors with Mark I containment vessels Number of reactors: 4 on site; 1 involved in accident: 6 on site; 4 (and spent fuel pools) involved in accident; one of the four reactors was empty of fuel at the time of the accident.
