WebA two fluid reactor that has thorium in the fuel salt is sometimes called a "one and a half fluid" reactor, or 1.5 fluid reactor. This is a hybrid, with some of the advantages and disadvantages of both 1 fluid and 2 fluid reactors. Like the 1 fluid reactor, it has thorium in the fuel salt, which complicates the fuel processing. http://canteach.candu.org/Info/Pages/CANDUReactors.aspx
WebThe Arrangement of Fuel, Coolant and Moderator in a CANDU Reactor 11.2.1 Fuel Most commercial reactors, including CANDU, use uranium dioxide fuel. CANDU is unique in using natural uranium. Natural uranium is 99.3% U-238, which is not fissile, and 0.7% fissile U-235. Most reactors use enriched fuel with 2% to 4% U-235. The chance of a WebApr 12, 2024 · CANDU technology continues to evolve to enable the use of alternative fuels. Work is under way in Chinese CANDU reactors to demonstrate that they can recycle used fuel from other nuclear power plants, reducing the volume of nuclear waste.
