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.

Although to most the term ‘fission reactor’ brings to mind something close to the commonly operated light-water reactors (LWRs) which operate using plain water (H 2 O) as coolant and with ...

So why not the atomic bomb? Nazi Germany ... end of the year the physicist Werner Heisenberg had calculated that nuclear fission chain reactions might be possible. When slowed down and controlled ...

Atomic bombs work by splitting atoms via nuclear fission. It's called "splitting" because, essentially, you're taking one atom and dividing, or splitting, it into two. The center of atoms consists ...

The discovery of nuclear fission was one of the greatest scientific milestones of the 20th century. It led to the atomic bomb, nuclear power, and a Nobel Prize in 1944 for German chemist Otto Hahn.
