Because the neutrons of a hybrid are supplied externally from the fissile fuel, there is no need to concentrate this fuel to maintain criticality. Thus a criticality accident in a hybrid is ...

As a result any isotope in the fuel that’s fissile can become part of the nuclear chain reaction, allowing this reaction to proceed until no further fissile elements remain in the fuel.

The U.S. agency in charge of nuclear security is commissioning a study on the proliferation risks of a more-enriched uranium ...

India has designed and is developing a reactor fuelled by thorium — the Advanced Heavy Water Reactor — which, according to Kakodkar, will serve as a demonstration not only for the thorium fuel cycle, ...

The objective of this meeting is to facilitate the exchange of information on viable technologies and approaches for the management (treatment and conditioning) of spent research reactor fuel and ...

However, there are ways to use thorium to create fissile materials suitable for fuel. Thorium-232 is the only naturally occurring thorium isotope, but it is fissionable rather than fissile.

The DOE is working to recycle EBR-II spent fuel as part of a larger effort to make HALEU. HALEU is enriched between 5 and ...

a future in which weapons-usable fissile material no longer poses risks of proliferation (vertical or horizontal) or from nuclear terrorism because it has been minimized or eliminated. This project ...

Rolls-Royce Submarines has announced the joint appointment of AtkinsRéalis and Mott MacDonald as its new fissile design ...

Expert Meeting to facilitate the participation of African and Asian States in the Fissile Material Cut-Off Treaty (FMCT) Consultative Process The meeting aimed to facilitate dialogue among ...
