WebCoolant water: Borated water is often used as the coolant for removing heat from the reactor core. Borates are added to the water, providing the added benefit of helping to control the fission rate in the reactor. The reactivity occurring in the plant can be adjusted by changing the boron level in the water. WebMar 1, 2007 · The nuclear process. Nuclear reactors use rods of solid fuel which are stored in metal tubes. The fuel rods are made of two isotopes of uranium: U-235 and U-238. The source of the power is the fission reaction. To initiate fission, the fuel is bombarded with neutrons, causing the unstable U-235 nucleus to split.
