Sentence examples for fissions from inspiring English sources

The continuing process whereby neutrons emitted by fissioning nuclei induce fissions in other fissile or fissionable nuclei is called a fission chain reaction.

An important aid in achieving criticality is the use of a tamper; this is a jacket of beryllium oxide or some other substance surrounding the fissionable material and reflecting some of the escaping neutrons back into the fissionable material, where they can thus cause more fissions.

This series of rapidly multiplying fissions culminates in a chain reaction in which nearly all the fissionable material is consumed, in the process generating the explosion of what is known as an atomic bomb.

Since the 1960s, pits have been made almost exclusively from plutonium, because it fissions faster, produces more neutrons and has a much smaller critical mass.

Fast reactors, in contrast, do not employ moderators and use much faster neutrons to produce fissions.

The reactor core consisted of pellets of uranium fuel inside bricks made of graphite, which served as a "moderator", reducing the speed of the neutrons in order to maximise their ability to cause further fissions.

He thinks that renewable sources of energy are not currently up to the task: "We need another generation of nuclear-fission stations".

The process releases large amounts of energy, much of it in the form of the kinetic energy of the fast-moving fission products.

It played host to the invention of nylon, nuclear fission and talking films.

A question of character Better ways to collaborate And the winners were... Powering the drive Read all about it Nuclear's next generation Fields of automation Son et lumière meets surgery Beyond the ether ReprintsAll nuclear reactors rely on nuclear fission, a process discovered in the 1930s.

This energy is converted to heat as the fission products slow down.
