Nuclear Weapons

Would it make a difference- I've seen Jersey.

The first event was not in the U.S., but it is the test site of Bikini Atoll in the Pacific Ocean. Tests that were done in the 1040s and 1950s have left their mark--still radioactive after all these years.

The accident at the Three Mile Island nuclear power plant near Middletown, Pa., on March 28, 1979 brought awareness of the dangers of nuclear power. Although there was no lasting environmental effect, communication to the public did raise fears.

It was a strategic decision; if something went wrong, it would only kill white trash sourherners. It was also determined that the genetic damage due to inbreeding in the region would greatly overpower any damage from radiation poisoning, so no one would notice.

Actually as part of the New Deal, the Tennesee Valley Authority built dozens of state of the art hydroelectric powerplants in the Oakridge area. Refining nuclear fuel required a massive amount of electrical power, so the location was ideal. Also the area was sparsely populated, minimizing the human risk.

American propaganda caused most Americans to believe that it was a horrible system.

Senator McCarthy also had a thing where there were people who would ask Americans "Are you now or have you ever been a communist?" Those who answered yes were in big trouble.

becaue if people3 do it in america you with go to juail

For the same reason they form following any explosion: heated air from explosion is lighter than surrounding air, making it buoyant and it therefor rises. The cloud is visible because of entrained debris, vaporized metal, smoke from fires, etc. produced by the explosion (nuclear or not). Nuclear mushroom clouds are simply more spectacular because more energy was released, making them hotter.

• Reactors use thermal (slow) neutrons, fission weapons use fast neutrons.
• Reactors all use fission, weapons can use fission, fusion, or any combination.
• Reactors can use delayed fissions making them respond slowly to control changes, weapons complete their reaction too fast for delayed fissions to happen.
• Reactors have control rods and their energy release can be adjusted or even turned off, weapons have no controls and release all their energy in a few microseconds once triggered.
• etc.

Probably too many.

It would probably create a localized ozone hole.

The Mk-18 bomb was also known as the SOB -- the Super Oralloy Bomb. It had a design yield of about 500 kilotons. With an advanced 92 point implosion system and over 4 critical masses of fissile material in the core (60kg highly enriched uranium pit, and a uranium tamper) it was a dangerous weapon -- even an accidental firing of one of the detonators causing a "fizzle" would have produced a significant nuclear yield (in the kiloton range).

The Hydrogen Bomb or H-bomb was not developed until the 1950's. It was only exploded during tests on land and in the ocean.

Nowhere. The first atomic bomb was made in Los Alamos, New Mexico.

However uranium was enriched in several large plants at Oak Ridge, Tennessee. This site was selected by the Manhattan Project due to the available of low cost electricity from the Tennessee Valley Authority, which was needed to operate the thousands of pumps in the Gaseous Diffusion enrichment process.

This uranium was used in the Little Boy bomb (the second atomic bomb detonated, the first atomic bomb used in combat) and at low enrichment levels in the Hanford plutonium production reactor's fuel.

That depends on its design: known fielded bombs have had yields from 0.1 kiloton to 57,000 kilotons. Bombs with lower and higher yield are definitely possible, if someone wanted to make them.

Only two person knew about the mission's details. The rest of the crew learned of the destruction when the weapon detonated. They could believe what they saw.

If by strongest you mean highest yield, I believe this would be Russia. Current treaties allow them higher yield weapons because their ICBMs are somewhat less accurate than US ICBMs.

The first Soviet nuclear weapon was tested in 1949. They have never used one in combat.

There are no safeguards since it can be sold by any government that own it.
