RBMK Reactor
The RBMK (russian: реактор большой мощности канальный, 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. The name refers to its design where, instead of a large steel pressure vessel surrounding the entire core, the core is surrounded by a cylindrical annular steel tank inside a concrete vault and each fuel assembly is enclosed in an individual 8 cm (inner) diameter pipe (called a "technological channel"). The channels also contain the coolant, and are surrounded by graphite. The RBMK is an early Generation II reactor and the oldest commercial reactor design still in wide operation. Certain aspects of the original RBMK reactor design, such as the large positive void coefficient, the 'positive scram effect' of the control rods and instability at low power levels, contributed to the 1986 Chernobyl disaster, in which a ...

Smolensk Nuclear Power Plant
Smolensk Nuclear Power Plant (russian: link=no, Смоленская АЭС []) is a nuclear power station in Russia. It is located in the Smolensk region, in Desnogorsk province, approximately 100 km from Smolensk, 115 km from Bryansk and 320 km from Moscow. Smolensk Nuclear Power Plant is the biggest power generating station in the north-western region of the united energy system of the Russian Federation. Smolensk NPP has an outer appearance similar to that of Chernobyl NPP units 3-4, as both are later generation RBMKs. Construction and operation Construction began on the Smolensk NPP in the late 1970s. The NPP was originally intended to be constructed in two phases with units 1 and 2 starting in 1975 and 1976. Followed by units 3 and 4 in the mid-late 1980s. Unit 3 began construction in 1984. However, the construction of the fourth reactor was interrupted by the Chernobyl disaster and plans were cancelled in 1993. The three RBMK-1000 reactors of Smolensk ...
