What are Nukes made of?

Nuclear weapons, or nukes, are made of radioactive materials such as plutonium or uranium, which undergo a controlled nuclear chain reaction to release a massive amount of energy in the form of a nuclear explosion. The process involves splitting atomic nuclei in a process called fission or combining them in fusion reactions. These materials are highly regulated and controlled due to their destructive potential.

Which is bigger atom bomb or nuclear bomb?

Both words are technically interchangeable, so your question cannot be answered as written.

Perhaps you meant which is bigger fission or fusion bomb?

Define bigger: size or yield?

The biggest bombs ever built in both size and yield have been fusion. But many modern fission bombs are bigger physically than fusion bombs with bigger yield and some fission bombs have bigger yield than some fusion bombs. Confused?

It all depends on purpose.

Can the atomic bomb be seen as progress?

I'm not quite sure what you mean as "progress". It appears to be a technology that somebody would have developed sometime in the timeframe of the 1940s, 1950s, or 1960s, even if WW2 had not accelerated the "need" for it. The idea of the neutron chain reaction required for it had already been patented in 1934 by Leo Szilard and the Uranium fission reaction needed to make it work had already been discovered in 1939 by Otto Hahn. The main thing that limits it is the specialized industrial infrastructure that needs to be developed to prepare the components. However it has more or less been shown that for a country sized entity, this takes roughly 4 years from decision to proceed to ability to make bombs.

How is an atomic bomb triggered by nuclear fission?

You mean what triggers the fission chain reaction?

The atomic bomb that was dropped on hiroshima was a gun style fission bomb that used a uranium-235 core. The core consisted of two hemispheres of U-235 on each side of a tube, with an explosive that would push them together. When they collide, they reach the critical mass for an uncontrolled chain reaction and nuclei start to split and release neutrons which will collide with other nuclei and split them as well. The explosive used to trigger the reaction is triggered by a detonator.

Can a nuclear bomb destroy a mountain?

That would depend on:

  • Size of mountain
  • Type of rock in mountain
  • Yield of bomb
  • Depth of burst in mountain (an air burst would have little effect on any mountain) This means either a placed charge or a rock penetrator bomb

My Nuclear Bomb Effects Computer circular slide rule computes that for a 20 Mton bomb surface burst (the slide rule is not calibrated beyond 20 Mtons and does not include underground bursts) results in a crater 660 feet deep and 2534 feet in diameter. The depth and diameter of the crater will increase with depth of burst, until a depth (depending on yield) at which the rock begins to contain the blast.

Extrapolating and decalibrating the slide rule for a 200 Mton bomb surface burst results in a crater 1,320 feet deep and 5,700 feet in diameter.

Much larger than this yield and most of the blast, even in a surface burst will simply blow away atmosphere above the burst into space.

Yes, a high enough yield device (there is no theoretical limit to the yield of a fusion bomb) at the right depth candestroy a mountain. However I would hate to be anywhere downwind as every speck of the mountain will come falling back as highly radioactive fallout.

What happens when a nuclear bomb hits a school?

Buildings are effected by the blast not by purpose but by construction (as with any bomb). Light wooden construction is flattened, reinforced concrete may survive with minor damage.

What is the first atom bomb called?

  • The first nuclear explosive tested was code named Gadget. July 16, 1945.
  • The first nuclear bomb dropped was code named Little Boy. August 6, 1945.

It remains unknown when the first atom bomb was created.

Is uranium used in nuclear weapons?

Yes, uranium is used in nuclear weapons, specifically in nuclear fission bombs. The two main isotopes of uranium used for this purpose are uranium-235 and uranium-238. When these isotopes undergo a fission chain reaction, a large amount of energy is released, leading to the explosive power of the nuclear weapon.

What is the difference between atom bombs and hydrogen bombs?

An atomic bomb is a fission bomb, which uses a type of heavy radioactive metal (usually uranium 235 or plutonium 239). Neutrons split this metal up, resulting in a release of a lot of energy (this is what happens in nuclear power stations).

A hydrogen bomb is a fusion bomb, which comes in two parts: a fission device (A-bomb) and a fuel cell composed of hydrogen. The fission device is detonated and the radiation fuses the hydrogen together to form helium, thus also releasing a lot of energy (this is what happens in stars).

Is hydrogen bomb deadly?

Yes, a hydrogen bomb is a type of nuclear weapon that can have devastating effects, causing widespread destruction and loss of life due to the large amount of explosive power it generates. The detonation of a hydrogen bomb can result in massive explosions, radiation exposure, and long-term environmental damage.

What is the different between atomic bomb and hydrogen bombs?

The main difference between atomic bombs and hydrogen bombs is the source of their energy. Atomic bombs rely on nuclear fission (splitting atoms), while hydrogen bombs use a two-stage process involving both fission and fusion (combining atoms). Hydrogen bombs are more powerful and destructive than atomic bombs.

Are nuclear bombs made with nuclear fusion?

Nuclear bombs can use either nuclear fission or nuclear fusion as the primary mechanism of energy release. Most nuclear bombs in current arsenals rely on nuclear fission reactions, while thermonuclear bombs use a fission reaction to trigger a fusion reaction.

How does the neutron bomb work?

A neutron bomb is a type of hydrogen bomb. It actually was a development that came from the late 1950s work by the US to make "clean hydrogen bombs" that produced very little fallout.

In a conventional hydrogen bomb the tamper (device to contain the nuclear reaction as long as possible to get as much energy from it as possible) is usually made with depleted uranium because of its high density and low cost. While depleted uranium will not support a neutron chain reaction it will fission when hit by the high energy neutrons produced by the fusion reaction of the hydrogen bomb. This depleted uranium fast fission can produce up to 90% of the total yield in some hydrogen bomb designs, as well as a proportional amount of the fallout.

In a "clean hydrogen bomb" the tamper is instead made of some other very dense metal that unlike uranium will not fission when hit by high energy neutrons. Lead and tungsten have been used. However the explosive yield of a "clean hydrogen bomb" will be lower than a similar conventional hydrogen bomb because there is no fission in the tamper.

But as these materials do not consume the high energy neutrons, they escape from "clean hydrogen bombs". It was observed that these neutrons easily pass through tank armor and building walls, killing those inside while the lower yield produces less blast and fire damage. Thus was born the idea of the neutron bomb.

How does a nuke create such a big explosion?

A nuclear bomb creates a big explosion through a process called nuclear fission, where the nuclei of atoms are split apart, releasing a huge amount of energy in the form of heat, light, and shock waves. This release of energy happens very quickly, causing a powerful and destructive explosion.

Is silver used in nuclear bombs?

In the bomb, no.

However the US first "calutron" mass spectrometer uranium enrichment machines in WW2 were built with silver (borrowed from the treasury) magnet windings, because copper was not available in the war because it was being used in making bullets and ammo casings. This silver was returned after the war.

Why are nukes bad for countries?

nukes are not "bad for countries" but they have devistating side affects, for example: the cities of nagisaki and hiroshima are still highly radiated due to the original atomic bombs which were droped there.

How is fusion used in a hydrogen bomb?

a hydrogen bomb is a fusion bomb. even though in standard types of hydrogen bombs 90% of the yield is fission, caused by uranium-238 fission by 15 MeV neutrons from the fusion reaction.

Is nuclear reaction good or bad?

Nuclear reactions can be both good and bad. They can produce clean energy, like in nuclear power plants, but also be used to create nuclear weapons which have destructive capabilities. The key is in how nuclear reactions are managed and controlled.

Would a non-nuclear bomb destroy a tornado?

Most likely not, though a large enough explosion might disrupt a small, weak tornado temporarily. The structure of a tornado is enormous, extending upwards for miles. Some of the largest tornadoes can be well over a mile wide, and most very destructive tornadoes are at least a quarter of a mile wide.

However, any explosive strong enough to disrupt a tornado would cause more damage that the tornado.

Can a nuclear reactor be used as a nuclear weapon?

No. LLNL even tested several Uranium-Hydride bombs in the 1950s. Even though their computer models said the devices should explode, none gave a nuclear yield.

One could use the waste from the reactor as a Radiological Weapon, but the reactor itself is not useful as a weapon.

Can Nuclear Weapons destroy the World?

While nuclear weapons have the potential to cause massive destruction, it is unlikely that they could destroy the entire world. However, a large-scale nuclear war could have catastrophic consequences for civilization, causing widespread devastation, loss of life, and long-term environmental impacts. Efforts to prevent the use of nuclear weapons are crucial for global security and peace.

Can Nuclear Weapons destroy the World and the planet?

Nuclear weapons have the potential to cause massive devastation, including widespread destruction and loss of life. However, it is unlikely that they could completely destroy the world or the planet itself. The use of nuclear weapons would have catastrophic consequences with long-lasting impacts on the environment and civilization.

How are nuclear weapons destroyed?

The only way that how are nuclear weapons are destroyed that these anti-nuclear working group stay together and work together to get these powerful nuclear weapons destroyed. It's possible to destroy nuclear weapons but it is a very hard and dangerous job. Want to know how nuclear weapons are destroyed? These people work as a team by staying together, they also disable nuclear missile launching systems to prevent the nuclear weapons from being launched. They work very carefully to make sure that the nuclear weapon cannot make wide explosions. They destroy the missile very carefully so that the missile cannot make very huge nuke explosion. They also stop nuclear bombs from being dropped by making sure that the bomb is destroyed but they have to place something to destroy the nuclear bomb and they must be very careful because nuclear missiles and nuclear bombs are very powerful. There should be a time bomb to destroy these weapons and don't let these weapons create big explosions. If there is then they place the time bomb on nuclear weapon, they also have to move very far away from the weapon to make sure that they are safe and can't get killed. To destroy nuclear weapons, these nukes have to be sent very far away from the city or from the town so people can't get killed by the nukes.

What is meant by supercritical and how does it relate to making a nuclear bomb?

  • A subcritical mass cannot sustain a nuclear chain reaction, it dies exponentially
  • A critical mass can sustain a nuclear chain reaction, but it remains constant neither increasing nor decreasing
  • A supercritical mass not only sustains a nuclear chain reaction but it increases exponentially until the mass explodes

A nuclear fission bomb must become supercritical at some time in order to explode.

What is meant by supercritical andhow dose it relate to making a nuclear bomb?

  1. subcritical - a mass or arrangement of fissionable or fissile material unable to sustain a neutron chain reaction. It can provide a fixed amount of neutron multiplication from a neutron source, but after removal of the neutron source the chain reaction rate drops exponentially.
  2. critical - a mass or arrangement of fissionable or fissile material capable of sustaining a constant neutron chain reaction. No increase or decrease. (Nuclear reactors operate at critical)
  3. supercritical - a mass or arrangement of fissionable or fissile material capable of not only sustaining a neutron chain reaction, but once initiated the chain reaction rate rises exponentially. (Nuclear fission bombs explode when made supercritical)

A nuclear fission bomb must have 2 of these states: subcritical (so that it can't explode until desired) and supercritical (so that it explodes with an effective yield). This requires a rapid "assembly" system using conventional explosives to rearrange the fissile material from subcritical to supercritical in about 1ms. A neutron source starts the chain reaction and the explosion completes in about 1 microsecond.
