how is a nuclear bomb made ?

Question

please give me a simple answer bcoz i am a 14 year old.

Answer 1

The world's first nuclear explosion was achieved with plutonium, a man-made element produced in nuclear reactors. Plutonium is created when an atom of uranium-238 absorbs a neutron and becomes plutonium-239. The reactor generates the neutrons in a controlled chain reaction. For the neutrons to be absorbed by the uranium their speed must be slowed by passing them through a substance known as a "moderator." Graphite and heavy water have been used as moderators in reactors fueled by natural uranium. For graphite to succeed as a moderator it must be exceptionally pure; impurities will halt the chain reaction. Heavy water looks and tastes like ordinary water but contains an atom of deuterium instead of an atom of hydrogen. For heavy water to succeed as a moderator, it too must be pure; it must be free of significant contamination by ordinary water, with which it is mixed in nature.

The world's second nuclear explosion was achieved with uranium-235. This isotope is unstable and fissions when struck by a neutron. It is, however, found in natural uranium at a concentration of only 0.7 percent. To be useful in nuclear weapons, the concentration must be increased. This is accomplished by a process known as enrichment. Because the isotopes of uranium are identical chemically, the enrichment process exploits the slight difference in their masses. Nuclear weapons now use a concentration of 93.5 percent uranium-235.

Answer 2

Theoretically, bomb neutrons on U-235 (probably a few mgs) using an accelerator in a controlled mechanism (using barium and cadmium rods) such that these rods absorb most of the neutrons and rest of the neutrons keep on striking other U-235 atoms. Don't remember the chemical equation but elements like thorium and radium are produced finally.

# First, obtain about 50 pounds (110 kg) of weapons grade Plutonium at your local supplier (see NOTE 1). A nuclear power plant is not recommended, as large quantities of missing Plutonium tends to make plant engineers unhappy. We suggest that you contact your local terrorist organization, or perhaps the Junior Achievement in your neighborhood.
# Please remember that Plutonium, especially pure, refined Plutonium, is somewhat dangerous. Wash your hands with soap and warm water after handling the material, and don't allow your children or pets to play in it or eat it. Any left over Plutonium dust is excellent as an insect repellant. You may wish to keep the substance in a lead box if you can find one in your local junk yard, but an old coffee can will do nicely.
# Fashion together a metal enclosure to house the device. Most common varieties of sheet metal can be bent to disguise this enclosure as, for example, a briefcase, a lunch pail, or a Buick. Do not use tinfoil.
# Arrange the Plutonium into two hemispheral shapes, separated by about 4 cm. Use rubber cement to hold the Plutonium dust together.
# Now get about 100 pounds (220 kg) of trinitrotoluene (TNT). Gelignite is much better, but messier to work with. Your helpful hardware man will be happy to provide you with this item.
# Pack the TNT around the hemisphere arrangement constructed in step 4. If you cannot find Gelignite, fell free to use TNT packed in with Playdo or any modeling clay. Colored clay is acceptable, but there is no need to get fancy at this point.
# Enclose the structure from step 6 into the enclosure made in step 3. Use a strong glue such as "Crazy Glue" to bind the hemisphere arrangement against the enclosure to prevent accidental detonation which might result from vibration or mishandling.
# To detonate the device, obtain a radio controlled (RC) servo mechanism, as found in RC model airplanes and cars. With a modicum of effort, a remote plunger can be made that will strike a detonator cap to effect a small explosion. These detonatior caps can be found in the electrical supply section of your local supermarket. We recommend the "Blast-O-Mactic" brand because they are no deposit-no return.
# Now hide the completed device from the neighbors and children. The garage is not recommended because of high humidity and the extreme range of temperatures experienced there. Nuclear devices have been known to spontaneously detonate in these unstable conditions. The hall closet or under the kitchen sink will be perfectly suitable.
# Now you are the proud owner of a working thermonuclear device! It is a great ice-breaker at parties, and in a pinch, can be used for national defense

Answer 4

You need to get very very good grades so you can go to one of the best universities in the world. Become nuclear physicist and become employed ay a top secret government institute in one of the countries that makes nuclear weapons. Then you can find out.

Answer 5

Steamroller98439 does know his stuff.
For the information of the questioner and all others who talk about "chemical reactions" -- those don´t happen in a nuclear device, nuclear reaction are physical, therefore the question should be in the "physics" section.

Answer 6

If you are serious, OK. This is the type of question that gets scrutinized. With all the terrorist activity going on in the world, your question sends up a red flag.
Basically it is called splitting the atom. I don't know much more than that. Good luck.

Answer 7

You put a ball of a few pounds of refined uranium in the center
of a bunch of conventional explosives ( dynamite ) and set off
the dynamite...It smashes the uranium together and heats it up
which starts the nuclear reaction...

Answer 8

Just stick around for a week. This question gets asked on the average about once a week.

Answer 9

it is made with lots of adults working in top secret facilities.

Answer 10

Why would you you need to know that? You a terrorist?
