Weapons grade plutonium has min. 93 % plutonium-239.
The cost of weapons grade plutonium (more than 93 % Pu-239) is appreciated at 4 000 000 US $/kg.
Plutonium
Plutonium is used as nuclear fuel for nuclear reactors to produce electric energy. Also plutonium is indispensable for nuclear weapons.
Plutonium is very useful in nuclear weapons or nuclear fuels but is toxic, radioactive and expensive.
Uranium or plutonium
Weapons grade plutonium has min. 90 % plutonium 239 and max. 1 % plutonium 240.
Reactor grade material is usable in most nuclear power plants. Weapons grade material is required for nuclear weapons. For uranium the difference between reactor grade and weapons grade is the level of enrichment: less than 20% uranium-235 is reactor grade, greater than 20% uranium-235 (greater than 90% is prefered) is weapons grade. For plutonium the difference between reactor grade and weapons grade is the level of contamination with plutonium-241: any amount of plutonium-241 is OK for reactor grade, only low levels of plutonium-241 are acceptable in weapons grade as its spontaneous fission rate can cause the bomb to fizzle.
Approx. 4ooo US $ per gram for nuclear weapons quality plutonium; the price for nuclear reactors grade plutonium is lower.
Plutonium production energy are designed to produce weapons grade plutonium, not electric energy or heat.
No nuclear plant I know of uses weapons grade fissile material. This is strictly controlled for military use only.
The price of nuclear weapons grade plutonium is approx. 4 000 US $ for one gram, in 2010.
The cost of weapons grade plutonium (more than 93 % Pu-239) is appreciated at 4 000 000 US $/kg.
most cannot, as to produce weapons grade plutonium the fuel cycle must be made very very short. however soviet RBMK reactors and the US hanford N reactor were designed explicitly to produce both electric power and weapons grade plutonium.
Plutonium for nuclear weapons is obtained in special nuclear reactors for plutonium-239.
Only if it runs on weapons grade plutonium.
Applications of plutonium: * explosive in nuclear weapons * nuclear fuel in nuclear power reactors * the isotope 238Pu is used as energy source in spacecrafts or other applications (radioisotope thermoelectric generators); the chemical form is plutonium dioxide. * neutron generator, as Pu-Be sourceThe price of weapons grade plutonium is cca. 4 000 $/g.
The mass number of the most important isotope of plutonium (239Pu) is 239. For the other isotopes see the link below; mass number = number of protons + number of neutrons).
