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

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 ...

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 ...

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

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 ...

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

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 ...

Unlike nuclear fission, the nuclear fusion reaction in a tokamak is an inherently safe reaction. But fusion is a finely balanced reaction which is very sensitive to the conditions. The reaction ...

I study nuclear physics and fusion ... If a malfunction occurs, the reaction simply stops, avoiding any dangerous chain reactions. As research progresses, international projects like ITER are ...
