Sentences with phrase «by nuclear fission reactors»

Because it is our generation that will benefit from the wealth produced by nuclear fission reactors, all our heirs will receive is our radioactive garbage.

A short while later, the Europa mission came back to life, when it was linked with an experimental ion propulsion system powered by a nuclear fission reactor, the pet idea of Sean O'Keefe, then NASA's administrator.

Not exact matches

All commonly used medical radioisotopes can be produced without using nuclear reactors or enriching uranium, or can be replaced with other isotopes that can be produced without a fission reaction, or by alternative technologies.

Today's nuclear reactors do dramatically better by splitting uranium atoms through fission, but they still fail to extract more than 0.08 percent of their energy.

The idea remains that fast reactors, which get their name because the neutrons that initiate fission in the reactor are zipping about faster than those in a conventional reactor, could offer a speedy solution to cleaning some nasty nuclear waste, which fissions better with fast neutrons, while also providing electricity as a by - product.

Enriched uranium oxide is formed into rods and water is used both as a coolant, flowing through the reactor core to transfer heat away, and as a moderator, slowing down neutrons released by fission so that they promote further nuclear reactions.

Antineutrinos are a by - product of the fission in a nuclear reactor, in which an atomic nucleus of a radioactive element such as plutonium splits into lighter elements.

Szilard had many ideas about the reactor design, and it was at this time that he actually thought up a name to the «nuclear breeder reactor,» which is supposed to make more fuel than it consumes by bombarding uranium - 238, which does not fission, turning it into plutonium - 239, which does fission.

The reactor overhead generates hydrogen by neutron - emission followed by neutron - decay to hydrogen, just like nuclear fission reactors.
