Reactor channeling
WebThe 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 … WebIn chemical engineering, channeling is an undesired phenomenon occurring in the reactor. It simply means the reactants are bypassing to the outlet without spending any time in the reactor. So the reactant doesn't spend any time in the reactor to react away and instead is …
