Reactor-grade uranium is not suitable for making a bomb because it contains a lower concentration of the fissile isotope U-235, which is necessary for sustaining a nuclear chain reaction required for a bomb to explode. The U-235 content in reactor-grade uranium is too low to achieve the rapid and efficient chain reaction needed for a nuclear explosion.
a uranium bomb is a fission bomb using uranium as the fuela plutonium bomb is a fission bomb using plutonium as the fuela composite bomb is a fission bomb using both uranium and plutonium as the fuela levitated core bomb is a fission bomb with an air gap between the uranium-238 tamper and the fuel core to increase compression of the fuel, efficiency, and yielda wet bomb is a fusion bomb using a cryogenic liquid mixture of deuterium/tritium as the fuela dry bomb is a fusion bomb using solid lithium deuteride as the fuela boosted bomb is a fission bomb using a tritium gas fusion "booster"a "clean bomb" is a fusion bomb with the uranium-238 radiation casing/tamper replaced with a material intended to reduce fallouta "dirty bomb" or "salted bomb" is a fusion bomb with the uranium-238 radiation casing/tamper replaced with a material intended to increase fallouta radiological bomb (sometimes incorrectly called a dirty bomb) is a conventional bomb wrapped in a jacket of radioactive isotopesa radiological weapon is a device, not using explosives, designed to disburse a large quantity of radioactive isotopes over a large areaI hope this clarifies some things.
Probably approx. 40 kg of enriched uranium.
Highly unlikely if not altogether impossible. In a core meltdown, you might see a steam explosion if the core melts and breaches the containment structure and hits say cooling water. But even a runaway chain reaction in a reactor would not cause a nuclear explosion like a bomb.
No, a reactor is operated at critical and a bomb at supercritical. Also reactors include safety shutdown systems that quickly make them subcritical stopping the reaction.However reactors can have steam explosions and hydrogen/oxygen explosions. These are physical and chemical explosions respectively, not nuclear.
The "Little Boy" bomb used in the Hiroshima bombing was a fission bomb, specifically a gun-type uranium-235 bomb. It relied on the nuclear fission of uranium-235 to release a massive amount of energy.
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.
Either highly enriched uranium-235 or reactor produced plutonium.
At this time:in a bomb, very cheapin a reactor, not yet possible
Some of the isotopes occur in nature. For example, in nature there is Uranium 238, and Uranium 235, but only Uranium 235 can directly be used for a power plant (or for an atomic bomb). Uranium is collected, and the isotopes must then be separated. This requires some rather advanced technology.Sometimes isotopes are created at a reactor. Some material, perhaps Uranium 238, is kept close to the reactor, and while it absorbs neutrons, it changes to another element and isotope, one that can be used in a nuclear reactor.
It was both: an atomic bomb using uranium as its fuel.
Hiroshima bomb: uranium Nagasaki bomb: plutonium
A uranium bomb is an atomic bomb fueled by uranium-235A plutonium bomb is an atomic bomb fueled by plutonium-239A composite bomb is an atomic bomb fueled by both uranium-235 and plutonium-239A wet bomb is a hydrogen bomb fueled by liquefied deuterium/tritiumA dry bomb is a hydrogen bomb fueled by solid lithium deuteride
A bomb containing highly enriched uranium (in the isotope 235U) as explosive.
The uranium isotope that is actually useful (whether for a reactor, or for an atomic bomb) is U-235. Natural uranium contains only about 0.7% of this; the remainder is mainly U-238. Therefore, it must be enriched, to have a greater percentage of U-235.
Yellow-cake isn't a natural substance. It's formed by the processing of Uranium Ore with chemicals and grinding, the first step to enriching Uranium for use in a reactor or a bomb. I guess you could describe it as an 'Ore'
atomic
Yes,well and truly it was.In fact,a uranium bomb is one of a rare bomb made.
