possible fissile isotopes usable as fuel:
The first bomb exploded, the Trinity test bomb, used plutonium. The first bomb deployed, dropped on Hiroshima, used uranium 235. The second bomb deployed, dropped on Nagasaki, used plutonium 239.
The Little Boy bomb, dropped on Hiroshima in 1945, used enriched uranium-235 as its fuel. This type of bomb is known as a uranium-based atomic bomb, and it functions through the process of nuclear fission.
The references I have state Oralloy is 93.5% U235. Oralloy (Oak Ridge Alloy) was used in US Uranium atomic bombs as the fissile material. However they also say that any enrichment 20% U235 or higher is fissile and could be used to make a bomb, it would require a higher critical mass to work though. One source I have states that early Soviet Uranium atomic bombs used ~97% U235, but the US felt this level of enrichment to be unnecessary and excessively expensive.
A nuclear bomb is any bomb with any nuclear or atomic material inside it, while a plutonium bomb is a specific type of nuclear bomb. Plutonium could be the nuclear material inside the bomb, and if it is, it's a plutonium bomb.
Yes, fluoride is sometimes used in the production of nuclear weapons to help purify and enrich uranium for fuel or bombs. However, the amount of fluoride present in an atomic bomb itself is typically very small and not a primary component of the weapon.
fissile material: highly enriched uranium or plutonium
It takes very little time to build an atomic bomb, once a country has the necessary industrial infrastructure to produce the fissile material.
An atomic bomb is a complete deliverable bomb, including all nonnuclear components. The nuclear core is a rather small part, typically between 2 to 3 inches in diameter that contains the fissile fuel that when made supercritical by conventional explosives in the bomb fissions and provides the energy to drive the actual nuclear explosion.
It was both: an atomic bomb using uranium as its fuel.
The fissile fuel is packaged in the bomb as a subcritical mass.The fusing system detects the preset firing condition.A firing pulse is sent from the fusing system to the rapid assembly system.The rapid assembly system uses explosives to repackage the fissile fuel as a supercritical mass.A neutron source fires through the supercritical mass, initiating the chain reaction.The chain reaction increases exponentially until the resulting explosion disassembles the fissile fuel back to a subcritical mass.
Fuel used in a nuclear reactor is uranium, the active isotope is uranium 235 which is fissile.
The atomic bomb is sphere shaped and weird. An atomic explosion is made by taking two halves of a critical mass of fissile material (plutonium or U235) and pushing them together very rapidly. Atomic bombs use conventional explosives to move the fissile material fast enough. If it does not move fast enough it just overheats and melts, rather than exploding. That's the key to designing an atomic bomb. Good luck!
It has to be a fissile material. Uranium 233, 235. Plutonium, 239, 241. Americium, 241. Others exist.
Breeder reactors were developed to allow use of non-fissile or fertile fuel, such as uranium-238 and thorium-232, instead of fissile fuel, such as uranium-235 and plutonium-239. They do have fissile fuel in them, but they use its neutron flux to convert the non-fissile (fertile) fuel into fissile form, extending the lifespan of the core.
A nuclear bomb and an atomic bomb are actually the same thing. Both terms refer to a type of explosive device that releases energy by nuclear reactions. The power of the explosion depends on the type of nuclear reactions involved and the amount of fissile material present in the bomb.
The first bomb that was used on people (Little Boy) used Highly Enriched Uranium as its fissile material. The first tested bomb at the Trinity Test used Plutonium as its fissile material.
The first bomb exploded, the Trinity test bomb, used plutonium. The first bomb deployed, dropped on Hiroshima, used uranium 235. The second bomb deployed, dropped on Nagasaki, used plutonium 239.
