Each fission reaction releases a huge amount of energy (about 200 MeV) but requires a chain reaction for the reactor to remain self-sustaining. By comparison, a fusion reactor generates an ...

They had also developed a nuclear reactor design that almost, but not quite, achieved a controlled and sustained nuclear fission chain reaction. During the last months of the war, a small group of ...

Any fission reactor basically works the same ... If you balance it right, the atoms breaking apart will cause a chain reaction that sustains itself. That is, neutrons hit atoms, releasing more ...

Many of the features of the reactor are designed to control the speed of the reaction and the temperature inside the shielding. An uncontrolled fission reaction is the basis of an atomic bomb.

The Nuclear Safety And Security Commission noted on the 24th that it would allow the restart of the Saewool Unit 1 nuclear ...

No, because fusion energy production is not based on a chain reaction, as is fission. Plasma must be kept at very high temperatures with the support of external heating systems and confined by an ...

The film discusses the dual nature of atomic energy, likening it to the sun, which can both sustain and destroy life. It ...

Nuclear fission close nuclear fissionThe splitting of a large nucleus to produce two smaller ones. Two or three neutrons are also released in the process. The energy from the neutrons powers a ...

Nuclear fuel debris that was extracted from the damaged Fukushima Daiichi nuclear power plant last year has been revealed to reporters for the first time.
