There are a two main types of Uranium, called isotopes, that are found in nature: Uranium-235 and Uranium-238. More than 99 per cent of all Uranium found on Earth is 238.

IN their classic paper1 discussing the theory of the fission process, Bohr and Wheeler estimated the energy release to be expected in binary, ternary and quaternary fission of the compound nucleus ...

Natanz, Isfahan and Fordow, killing several Iranian nuclear scientists. The facilities are heavily fortified and largely underground, and there are conflicting reports of how much damage has been done ...

Uranium is a story of duality. It is a mineral pulled from ancient rocks that can light up a city or wipe one off the map. It’s not just a relic of the Cold War or science fiction. It’s real, it’s ...

IN the study of the slow-neutron ternary fission of uranium-235, there is evidence that short-range particles of greater mass than α-particles are emitted. Dewan and Allen1 have reported ...

This is why for certain types of fission reactors that use slow neutrons the uranium fuel is ‘enriched’, meaning that the amount of U-235 in it is increased from the approximate natural 0.7% ...

A piece of uranium ore. Petr David Josek/AP In 1942, physicist Enrico Fermi and a team of workers built what they thought was the first nuclear reactor in a Chicago racket ball court.

Natural uranium is 99.3% uranium-238 (U-238) and only 0.7% is uranium-235 ... If recycled, the fission products are removed, the actinides and unused uranium are re-fabricated into new fuel, ...

When Israeli aircraft recently struck a uranium-enrichment complex in the nation, Iran could have been days away from ...

Uranium-235 has 92 protons (because it's uranium) and 143 neutrons (because 235 - 92 = 143). Oh, one more fact for the next time you are at a party. ... After this nuclear fission reaction, ...
