Used nuclear fuel is a complex mixture of the fission products, uranium, plutonium, and the transplutonium metals. In fuel which has been used at high temperature in power reactors it is common for the fuel to be heterogeneous; often the fuel will contain nanoparticles of platinum group metals such as palladium. Also the fuel may well have ...
Nuclear power is the use of nuclear reactions to produce electricity. Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions. Presently, the vast majority of electricity from nuclear power is produced by nuclear fission of uranium and plutonium in nuclear power plants.
The "Coulomb barrier" is the quantity of kinetic energy required to move the fuel atoms near enough. Atoms can be heated to extremely high temperatures or accelerated in a particle accelerator to produce this energy. An atom loses its electrons once it is heated past its ionization energy. An ion is the name for the resultant bare nucleus. The ...
Nuclear fusion is the reverse of nuclear fission, which powers the nuclear plants we’re all familiar with. Fission splits atoms of very heavy, unstable isotopes like uranium 235 and captures the ...
Nuclear fuel pellets are used to release nuclear energy. The most common type of nuclear fuel used by humans is heavy fissile elements that can be made to undergo nuclear fission chain reactions in a nuclear fission reactor; nuclear fuel can refer to the material or to physical objects (for example fuel bundles composed of fuel rods) composed ...
The plant set to be built at the Idaho National Laboratory, a research facility where Oklo has been given an Energy Department grant to test recycling nuclear waste into new fuel.
Nuclear fusion–fission hybrid (hybrid nuclear power) is a proposed means of generating power by use of a combination of nuclear fusion and fission processes. The concept dates to the 1950s, and was briefly advocated by Hans Bethe during the 1970s, but largely remained unexplored until a revival of interest in 2009, due to the delays in the ...
Workers have begun loading radioactive fuel into a second new nuclear reactor in Georgia, utilities said Thursday, putting the reactor on a path to begin generating electricity in the coming months.
