The fuel is composed of a 0.35-mm diameter fuel kernel of uranium (UO 2, UCO, or UC 2) surrounded by four coating layers: porous carbon buffer, inner pyrolytic carbon (IPyC), silicon carbide (SiC), and outer pyrolytic carbon (OPyC), respectively. Their function is to provide highly localised heating of sensitive equipment (such as electronics in outer space). It reacts with water, preventing long-term storage of spent fuel under water. Neutrons are an unwanted byproduct of fusion reactions in an energy generation context, because they are absorbed by the walls of a fusion chamber, making them radioactive. Fusion of the lightest atom, 1H hydrogen, as is done in the Sun and stars, has also not been considered practical on Earth. Sodium-bonded fuel consists of fuel that has liquid sodium in the gap between the fuel slug (or pellet) and the cladding. This advantage was conclusively demonstrated repeatedly as part of a weekly shutdown procedure during the highly successful 4 year Molten Salt Reactor Experiment.

Reprocessed uranium from Russian VVER reactor spent fuel is used to fabricate RBMK fuel. Larry Cutlip, left, Centrus Energy vice president of field operations, and Pete Pappano, X Energy vice president of fuel production, announce a collaboration on fuel for … Metal fuels have the advantage of a much higher heat conductivity than oxide fuels but cannot survive equally high temperatures. Our preliminary results on neutron irradiated TRISO coated particles reveal a grain boundary containing multiple FPs [2]. TRISO fuel particles are designed not to crack due to the stresses from processes (such as differential thermal expansion or fission gas pressure) at temperatures up to 1600 °C, and therefore can contain the fuel in the worst of accident scenarios in a properly designed reactor.
