Scientists have built the first-ever thorium reactor. Thorium is both more easily accessible and less dangerous than ...

More than 440 commercial reactors generate almost 10 percent of global electricity, a carbon‑free flow that has quietly been ...

Fermi, among others, realized that nuclear ... chain reaction. He did this by setting up the equipment -- atomic pile -- so that he could insert a neutron-absorbing material into the midst of the ...

Nuclear fission close nuclear fissionThe splitting ... The fast-moving neutrons carry most of the energy from the reaction with them (99%) but before the neutrons can collide with fresh uranium ...

IN a previous article 1 we directed attention to the resemblance between curves representing the division of electrically charged liquid drops and mass yield curves for nuclear fission.

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.

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 ...

What’s the difference between nuclear fission and nuclear fusion ... No, because fusion energy production is not based on a chain reaction, as is fission. Plasma must be kept at very high temperatures ...
