The design, known as the RBMK Reactor (see Fig 1.4), has been developed and enlarged, and many reactors of this type have been constructed in the USSR, including the ill-fated Chernobyl plant. The layout consists of a large graphite core containing some 1700 vertical channels, each containing enriched uranium dioxide fuel (1.8% U235). Heat is removed from the fuel by pumping water under ...

3.4.1.3 Fluidized‐bed Reactor. A nearly quantitative ethanol conversion with very high selectivity to ethylene can be achieved in the fluidized‐bed reactor. It also allows an optimum temperature control with minimized by‐product and coke formation. The conversion of ethanol is 99.5 % at 400 °C with a molar selectivity of 99.9 % to ...
