What are the four main components of a fission reactor?

Components of a Reactor

Any nuclear reactor that produces power via the fission of uranium (U-235) or plutonium (Pu-239) by bombardment with neutrons must have at least five components: nuclear fuel consisting of fissionable material, a nuclear moderator, reactor coolant, control rods, and a shield/containment system.

What are the components of nucleus?

The nucleus is composed of various structures namely nuclear envelope, nucleoplasm or nucleus sap nuclear matrix, chromatin and nucleolus. The nuclear membrane forms an envelope like structure around the nuclear contents and is commonly known as a nuclear envelope.

What was in the core of Chernobyl?

The Chernobyl corium is composed of the reactor uranium dioxide fuel, its zircaloy cladding, molten concrete, and decomposed and molten serpentinite packed around the reactor as its thermal insulation. Analysis has shown that the corium was heated to at most 2,255 °C, and remained above 1,660 °C for at least 4 days.
