This is the formidable energy of the nuclear fission.
Either highly enriched uranium-235 or reactor produced plutonium.
Uranium and Plutonium
The atomic number of plutonium (Pu) is 94. The atomic weight of Pu is approximately 244 grams per mole. See the Web Links and the Related Questions to the left of this answer for a periodic table and more information about this element.
And what is the question?
Uranium and plutonium are very heavy metals belonging to the element category actinide encompassing the 15 metallic chemical elements with atomic numbers from 89 to 103, actinium through lawrencium. Three uranium isotopes occur in nature versus only trace amounts of one isotope of plutonium. Of course the nuclear, chemical, physical and toxicological properties of uranium and plutonium are very different.
- the energy released from enriched uranium is higher compared to natural uranium- the amount of uranium needed for a reactor is lower- research reactors work only with enriched uranium- atomic bombs have highly enriched uranium or plutonium
Either highly enriched uranium-235 or reactor produced plutonium.
The atomic radii of uranium and plutonium are identical.
In their most stable forms, Uranium has an atomic mass of 238 and plutonium has an atomic mass of 244, plutonium has a greater mass than that of Uranium.
The atomic radii (empirical) of plutonium and uranium are identical - 175 pm.

Nothing special. Atomic bombs can be built with either uranium, plutonium, or composite (plutonium/uranium) cores. All work the same.
