WebThe fission process generates a huge amount of heat. In order to be useful, the heat has to be moved to boilers to make steam. In a CANDU® reactor, heavy water does this job. It is pumped constantly through the fuel channels in the reactor and takes the heat from the fuel bundles up to boilers above the reactor. WebNuclear reactors work by containing and controlling the physical process of nuclear fission. Radioactive decay of both fission products and transuranic elements formed in a reactor yield heat even after fission has ceased. Fission reactions may be moderated to increase fission, or unmoderated to breed further fuel.

WebJun 23, 2024 · Many nuclear reactors use ordinary water to cool the core and “moderate” the chain reaction, slowing neutrons so they are more likely to trigger fission. CANDU reactors use heavy water, in which deuterium takes the place of hydrogen, because it absorbs fewer neutrons, leaving more for fission. cincinnati city directories online
