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 ...

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

Nuclear fission is the basis of nuclear reactors and nuclear power plants. Nuclear reactors are devices in which a self-sustaining controlled chain reaction is produced in a fissionable material.

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.

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 ...

In 1939, much of the physics community was taken by the growing advances toward fission made by European ... home thinking about how to produce a chain reaction, Shockley came up with an idea ...

In their model, rumors act like neutrons, the small particles that kick off nuclear fission. These rumors are seen by individuals, who send them careening into other people in a chain reaction.

It’s a rare thing, this man-made lava, and it’s only produced when humans gather enough highly-radioactive isotopes to start a chain reaction. When a nuclear meltdown occurs, the fission ...
