The "Fat Man" atomic bomb, dropped on Nagasaki, Japan, on August 9, 1945, remains one of the most significant and terrifying ...

In the coming days or hours he will determine whether to join the effort and help Israel destroy the Fordow reactor, located 90 meters below ground, the stronghold completing the production of nuclear ...

Physicists have solved a long-standing puzzle about mercury’s nuclear fission by using a five-dimensional model that ...

Heretofore the prospects for beneficent applications of atomic energy have been limited to the fission chain reaction. In the fission reaction, neutrons are used to bombard the nuclei of suitable ...

A five-dimensional model has successfully predicted the asymmetric fission of mercury isotopes, offering new insights into ...

Compared to the plutonium still contained in CANDU spent fuel, the plutonium in the fresh fuel intended to be used in Moltex’s reactors would be far more accessible because it is no longer mixed with ...

Based on studying the prompt fission neutron spectrum of the induced fission of plutonium-240, researchers at LANSCE have found discrepancies with nuclear data libraries, especially on the energy ...

"Nuclear fission and related nuclear chain reactions were only discovered a little more than 80 years ago, and experimenters are still working to provide the full picture of fission processes for ...

In a standard light-water reactor (LWR) a few percent of U-235 is used up this way, after which fission products, mostly minor actinides, begin to inhibit the fission process, and fresh fuel is ...
