According to the patent application [5] the reactor design has some notable characteristics, that sets it apart from other reactor designs. It uses uranium hydride (UH 3) "low-enriched" to 5% uranium-235—the remainder is uranium-238—as the nuclear fuel, rather than the usual metallic uranium or uranium dioxide that composes the fuel rods of contemporary light-water reactors.
The transport from Gundremmingen to the Ahaus site met with considerable public protest and the power plant operators and the government later agreed to locate such casks at the powerplants. [ 18 ] CASTOR ( ca sk for s torage and t ransport o f r adioactive material) is a trademarked brand of dry casks used to store spent nuclear fuel (a type ...
In the light-water-cooled, graphite-moderated RBMK, a reactor type originally envisioned to allow both production of weapons grade plutonium and large amounts of usable heat while using natural uranium and foregoing the use of heavy water, the light water coolant acts primarily as a neutron absorber and thus its removal in a loss-of-coolant ...
Red: uranium-238, light green: plutonium-239, black: fission products. Intensity of blue color between the tiles indicates neutron density A traveling-wave reactor ( TWR ) is a proposed type of nuclear fission reactor that can convert fertile material into usable fuel through nuclear transmutation , in tandem with the burnup of fissile material.
And so using ordinary water as a moderator will easily absorb so many neutrons that too few are left to sustain a chain reaction with the small isolated 235 U nuclei in the fuel, thus precluding criticality in natural uranium. Because of this, a light-water reactor will require that the 235 U isotope be concentrated in its uranium fuel, as ...
Former SpaceX engineer Scott Nolan, CEO of startup General Matter, is on a mission to help end Russia's monopoly on a type of more-enriched nuclear fuel by producing it at commercial scale in the ...

The uranium trioxide is then mixed with pure hydrogen resulting in uranium dioxide and dihydrogen monoxide or water. After that the uranium dioxide is mixed with four parts hydrogen fluoride resulting in more water and uranium tetrafluoride. Finally the end product of uranium hexafluoride is created by simply adding more fluoride to the mixture ...
