It derived its explosive power from the nuclear fission of uranium 235.
uranium
Two uses of uranium are very important:- nuclear fuel for nuclear reactors- explosive for nuclear weapons
Nuclear power plants use controlled nuclear reactions to generate electricity and are not explosive in the same way as nuclear weapons or chemical explosives. While accidents at nuclear power plants can release harmful radiation, the likelihood of a nuclear explosion is extremely low due to safety measures in place.
Uranium or plutonium is typically used as the fissile material in explosive nuclear weapons. These elements undergo a nuclear chain reaction, releasing a large amount of energy in a short period of time, creating an explosion.
If by "bomb" you mean a conventional explosive weapon, then the nuclear weapon is more powerful.
A dirty nuclear bomb is detonated by using a conventional explosive. It disperses a large amount of nuclear material across the area.
To make a nuclear bomb, you need the fissionable material such as a Plutonium239 isotope, an explosive to start the nuclear chain reaction, a detonator, and a pusher.
Uranium - 235
The question you are asking is equivalent in many ways to asking "Which number is bigger 27 or 27?" as an atomic explosive and a nuclear explosive are generally considered the same. The only difference is a bomb is typically an explosive delivered by a manned airplane whereas the explosive warhead on a missile is delivered by either a rocket or an unmanned airplane called a cruise missile. Either one could be a higher yield explosive, or as I stated in the example at the beginning of this answer both could be identical.
Yes, there is nuclear energy in nuclear bombs. It is released in a few microseconds when they are detonated.
