nuclear reactor

Tightly sealed area where fission of the fuel is carried out in a controlled manner to release heat.
nuclear reactor Concrete structure surrounding the reactor vessel; it is a protective barrier against radioactivity. Tube that holds the fuel bundles and circulates the coolant at a preset pressure. The core of the nuclear reactor consists of tubular spaces where fission is produced and the coolant and moderator circulate. Water-filled basin where the spent fuel is stored for several years before it can be disposed of safely. Concrete structure surrounding the reactor vessel; it is a protective barrier against radioactivity. Fuel pencils that are grouped in parallel for introduction into the reactor. Small quantity of fuel that consists of powder pressed into a sheathing tube and then inserted into the metal cladding of the pencil.
