Nuclear power is a type of nuclear technology involving the controlled use of nuclear fission to release energy for work including propulsion, heat, and the generation of electricity. Nuclear energy is produced by a controlled nuclear chain reaction which creates heat—and which is used to boil water, produce steam, and drive a steam turbine.
In an implosion-type nuclear weapon design, a sphere of plutonium, uranium, or other fissile material is imploded by a spherical arrangement of explosive charges. This decreases the material's volume and thus increases its density by a factor of two to three, causing it to reach critical mass and create a nuclear explosion.
Neutron bombs would have been used if the REFORGER conventional response of NATO to the invasion was too slow or ineffective. [4] [36] Neutron bombs are purposely designed with explosive yields lower than other nuclear weapons. Since neutrons are scattered and absorbed by air, [2] neutron radiation effects drop off rapidly with distance in air.
The single-most important thing to remember if a nuclear bomb is supposed to explode, he says, is to shelter in place. "There were survivors in Hiroshima within 300 meters of the epicenter ...
With miniaturization, nuclear bombs can be delivered by both strategic bombers and tactical fighter-bombers. This method is the primary means of nuclear weapons delivery; the majority of US nuclear warheads, for example, are free-fall gravity bombs, namely the B61, which is being improved upon to this day.

The Cold War ended in 1991, but the looming threat of nuclear attack lives on with more than 14,900 nuclear weapons wielded by nine nations.. A terrorist-caused nuclear detonation is one of 15 ...
A nuclear explosion is an explosion that occurs as a result of the rapid release of energy from a high-speed nuclear reaction.The driving reaction may be nuclear fission or nuclear fusion or a multi-stage cascading combination of the two, though to date all fusion-based weapons have used a fission device to initiate fusion, and a pure fusion weapon remains a hypothetical device.
A Fractional Orbital Bombardment System (FOBS) is a warhead delivery system that uses a low Earth orbit towards its target destination. Just before reaching the target, it deorbits through a retrograde engine burn. [1] The Soviet Union first developed FOBS as a nuclear-weapons delivery system in the 1960s. It was one of the first Soviet efforts ...
