achieved a controlled and sustained nuclear fission chain reaction. During the last months of the war, a small group of scientists working in secret under Diebner and with the strong support of ...

Only one (or possibly two) of the missing bombs was fully assembled at the time it was lost. The total number of confirmed ...

This causes the nucleus to break apart and release additional neutrons that can trigger further fission reactions, resulting in a chain reaction. This reaction is the basis for current nuclear ...

In nuclear physics, a moderator is a substance that slows down the neutrons released from fission so they can sustain a chain reaction at a controlled rate. At Oklo, groundwater infiltrating the ...

Greg Piefer is a UW-Madison College of Engineering product who is bullish about fusion uses today while urging patience over ...

Yet despite improvements in the design of nuclear-fission reactors ... but requires a chain reaction for the reactor to remain self-sustaining. By comparison, a fusion reactor generates an ...

A second essential factor was that there needed to be a moderator for a nuclear chain reaction to occur and be sustained. In this case, the moderator was water, which slowed the neutrons down. Fission ...

The push for nuclear energy is part of India's commitment to achieve 500 GW of non-fossil fuel-based energy generation by ...

Further investigations 2 demonstrated the existence of at least nine radioactive periods, six of which were assigned to elements beyond uranium, and nuclear ... The whole 'fission' process can ...
