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 ...

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

But the technology required to implement this principle efficiently and safely is enormously complex. The fission chain reaction must be maintained at the correct rate and quickly adjusted or stopped ...

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.

After confirming that the reactor has reached a critical state where nuclear fuel is sustaining a fission chain reaction, the reactor will start generating electricity as early as Nov. 7.

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 ...

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 ...
