Sentences with phrase «fissile isotope»

Iran would have two basic options for achieving that reduction: exporting the excess LEU or blending it with depleted uranium, which, compared with natural uranium, has less of the fissile isotope uranium - 235.

This plant covers 74 acres and sucks up at least 300 megawatts of electricity most of the time, peaking at as much as 2,000 megawatts (much of it from a coal - fired power plant nearby), to heat uranium hexafluoride until it gasifies and then force it through 1,760 porous membranes that gradually concentrate the level of the fissile isotope — a method invented during World War II.

Reactors around the world require their fuel to hold anywhere from 3 to 5 percent U235, or 30 to 50 atoms of the fissile isotope per 1,000 atoms of uranium.

Dozens of civilian research reactors have closed or converted from HEU — uranium enriched to at least 20 % of the fissile isotope U-235 — to safer low enriched uranium (LEU), including 28 since 2009.

Those segments with potentially hazardous amounts of uranium - 235, the fissile isotope of uranium used in nuclear reactors and weapons, will be removed and decontaminated.

Not exact matches

This is fissile, and splits into lighter fragments, including isotopes such as caesium - 137, with a half - life of 30 years, and strontium - 90, with a 25 - year half - life.

In nature, uranium occurs as a mixture of two isotopes, the easily fissionable uranium 235 (which is said to be «fissile») and the much more stable uranium 238.

Some scientists have argued that thorium, a more abundant element that can be bombarded with neutrons to produce the fissile fuel isotope uranium233, could become the nuclear fuel of the future.

The fact that this isotope is a fissile material able to produce large amounts of heat and energy makes it highly useful in industries.

Uranium - 235 is the only fissile radioactive isotope which is a primordial nuclide existing in the nature in its present form since before the creation of Earth.
