By the end of the year the physicist Werner Heisenberg had calculated that nuclear fission chain reactions might be possible. When slowed down and controlled in a "uranium machine" (nuclear ...

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 ...

Reports suggest the justices are favoring Texas, though a ruling in the state’s favor could counter its recent efforts at ...

Molten Salt Reactors (MSRs) are nuclear fission reactors in which either the fuel and/or the coolant is a molten salt. Molten salt is salt which liquifies at elevated temperatures and can store ...

the heat produced by a controlled nuclear reaction is used to create steam pressure that drives a power-generating turbine. But the technology required to implement this principle efficiently and ...

In nuclear fission, atoms such as U-235 or Pu-239 split when a neutron hits them, releasing energy in the form of heat (along with more neutrons that can continue the chain reaction). This heat ...

It's this chain reaction that makes nuclear weapons so devastatingly powerful ... crews recovered only the "primary" fission section. The "secondary" fusion section was left in the ground, and the U.S ...

Most new nuclear fission reactors being built today are of the light water reactor (LWR) type, which use water for neutron moderation into thermal neutrons as well as neutron capture. While ...

Nuclear fission power plants have the disadvantage of generating ... No, because fusion energy production is not based on a chain reaction, as is fission. Plasma must be kept at very high temperatures ...

In nuclear physics, a moderator is a substance that slows down the neutrons released from fission so they can sustain a chain reaction at a controlled rate. At Oklo, groundwater infiltrating the ...

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.

Yet despite improvements in the design of nuclear-fission reactors ... but requires a chain reaction for the reactor to remain self-sustaining. By comparison, a fusion reactor generates an ...
