controlled nuclear fission chain reaction
(physics) capable of undergoing nuclear fission.
The time nuclear fission takes place vast energy is released.
At any time, nuclear fission will become a noticeable finding.
Some byproducts of the nuclear fission are themselves radioactive.
The uranium fuel generates heat by neutron-induced nuclear fission.
To cause to undergo nuclear fission or fusion.
"loss of or damage to insured property directly or indirectly caused or expenses incurred by nuclear fission, nuclear fusion, nuclear weapon, nuclear material, nuclear radiation and radioactive contamination;"
In some countries that secrecy stemmed from the military USES of nuclear fission.
Faith in controlled nuclear fission is now being shown by the construction of actomic power stations.
The energy produced during atomic nuclear fission is great enough to destroy the whole city.
All aspects of nuclear fission, whether nuclear expansion and Chernobi nuclear disaster or the ticking time bomb of radioactive waste, will be explored in depth.
As for economics, study after study rates nuclear fission one of the cheapest ways to make power.
Nuclear reactors work in a similar way to other power plants, But instead of using coal or gas to generate heat, they use nuclear fission reactions.
Still, in regard to energy independence and greenhouse gases, the benefits of nuclear fission have slowly softened Americans' overall attitudes toward a possible nuclear renaissance.
a nuclear weapon in which enormous energy is released by nuclear fission (splitting the nuclei of a heavy element (uranium 235 or plutonium 239)).
"The energy released from nuclear fission is used to generate electricity, to propel ships and submarines, and is a source of the vast destructive power of nuclear weapons."
"Mechanical explosives, which depend on a physical reaction (e.g., overloading a container with compressed air until it Bursts); Nuclear explosives (see nuclear weapon) use either nuclear fission or nuclear fusion."
Blowers move helium gas through the reactor and over the pebbles, where nuclear fission releases large amounts of energy, heating up the helium.
Electricity can be generated by nuclear fission, hydropower, biomass, wind and solar energy; and cars and lorries can run on electricity or biofuels.
Just weeks earlier, James Chadwick had discovered neutrons - the bullets of nuclear fission - and before long Enrico Fermi was shooting them at uranium atoms.
nuclear power: Energy produced by nuclear fission of heavy atomic nuclei. About one-third of all electric power worldwide now comes from nuclear power plants. The navies of many countries include nuclear-powered warships; almost half of U.S. combat warships are nuclear-powered.
Of course, when a certain amount of uranium is accumulated to a critical level and nuclear fission occurs, strong neutron lines trigger a chain reaction, which releases heat energy.
The first, supported by U.S. policy at the time, promised a future of steadily increasing reliance on dirty fossil fuels and nuclear fission, and it carried serious environmental risks.
There are several types of nuclear fission reactors in Japan, but we're going to focus on the Fukushima Naiishi plant, probably the most hard-hit facility in the country.
Nukes made 20 percent. in addition, nuclear fission differs from the burning of fossil fuel in that it produces neither sulfur dioxide nor nitrogen oxides, the pollutants that cause acid rain.
