The energy produced by natural radioactive disintegration is small an important only at geological times scale.
It depends upon the amount of uranium being used.However, the energy given out per nucleon per fission of uranium is 0.9 MeV.
This source is the fission energy.
Not exactly, but there are enormous reserves of nuclear fuel available. This is because a small amount of uranium, for example, or of deuterium, produce a large amount of energy.
Energy
The nuclear fission of uranium-235 release a huge amount of energy.This energy can be used in nuclear reactors to produce electricity/heat or in nuclear weapons.
No similarities: - uranium: energy released by fission - hydrogen: energy released by oxidation
1 kg uranium 235 = 3 000 t coal
availability is not everywhere. it can only produce a certain amount of energy at a time
About 1500 tons of coal
Nuclear energy from uranium fission is not inexhaustible, because there is only a certain amount on Earth and we cannot recreate or manufacture it.
When fissioned it produces thermal energy (heat)
Nuclear energy via radiation.
