nuclear fission

(General Physics) the splitting of an atomic nucleus into approximately equal parts, either spontaneously or as a result of the impact of a particle usually with an associated release of energy. Sometimes shortened to: fission Compare nuclear fusion

Generating electricity from nuclear fission can be said to be the Devil's work, whilst the pursuance of nuclear fusion can be said to be that of a quest for the Holy Grail.
FOR the sake of future generations we should be very alert and vigilant to the potential of dumping nuclear waste off the coast of Wales - or indeed under the Welsh mainland - we must not be seen as a soft option and have other countries queuing up to dump their unwanted nuclear waste in Wales But it is not just the dumping of nuclear waste, as we should all be protesting vociferously against the actual building of nuclear fission power stations - especially that of Hinkley Point (with Chinese finance), just across the Bristol Channel.
To address these needs we propose a CDT in Nuclear Energy (GREEN), a partnership between 5 of the UK's leading nuclear universities and 12 industry partners, addressing EPSRC priority area 19: Nuclear Fission & Fusion for Energy.
He discovered nuclear fission, which made the atomic bomb possible.
One way to release this energy is through nuclear fission, a process by which the nucleus of an atom is broken apart to create two smaller atoms.
That's why NASA has been developing small-scale nuclear fission reactors.
NASA has successfully demonstrated the working of its Kilopower Nuclear Fission Reactor - a system designed to power bases on moon, Mars, and beyond and make deep-space exploration a reality.
The singlet fission process is similar to nuclear fission. It involves splitting atomic nuclei to create two lighter atoms from a heavier one.
Department of Energy, at a news conference in Las Vegas, detailed the development of the nuclear fission system under NASA's Kilopower project.
For a great many of us, the spectre of events such as Chernobyl, Three-Mile Island, or the more recent disaster at Fukushima in Japan have cast a shadow over the idea of relying on nuclear fission to provide our energy needs as we race into an ever-more power demanding future.
According to the company, in the period between 2010 and 2015 ROSATOM declared more than 250 patents in the field of thermonuclear fusion and in the main area of nuclear energy based on nuclear fission. As Thomson Reuters points out, most of the patent activity of ROSATOM in this period focused on several areas, including technologies of inertial confinement fusion and technologies of magnetic confinement of hot fusion plasma.
