"Infectious disease models may mostly view the spread of rumors as a passive process ... fission. These rumors are seen by individuals, who send them careening into other people in a chain reaction.

Each fission reaction releases a huge amount of energy (about 200 MeV) but requires a chain reaction for the ... of neutrons to drive the fission process, a conventional nuclear reactor must ...

There are no CO 2 or other harmful atmospheric emissions from the fusion process, which means that fusion does ... No, because fusion energy production is not based on a chain reaction, as is fission.

Scientists have discovered that a piece of uranium extracted from an African mine is a two billion-year-old natural nuclear ...

It says this can be done using conventional low-enriched uranium fuel and an existing supply chain. Deep Fission is currently in pre-application engagement with the US Nuclear Regulatory Commission ...

Also like most of its peers, Deep Fission has yet to receive a license from the Nuclear Regulatory Commission. The startup began the process in March. In the past, it could take years to receive ...

Fusion: A nuclear reaction where two light atomic nuclei combine to form a heavier nucleus, releasing energy in the process. Fission: A nuclear reaction in which a heavy nucleus splits into two or ...

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 ...

Back in the 1950s, the U.S. started detonating nuclear bombs underground to limit the fallout, both radioactive and sociopolitical, unleashed by aboveground testing. Hundreds of feet of rock ...
