Richard Rhodes books "The making of the Atomic Bomb" and "Dark Sun" have some reasonable diagrams to go by.
Active material as well as the entire design.
Originally it was military uses, as well a nuclear weapon design and cryptography. Now it is nuclear weapon stockpile stewardship and gaming.
I could give you a few answers Implosion design Gun-type design Or I could also say Nuclear Weapon Thermonuclear Weapon aka Atomic Bomb Hydrogen Bomb
No. LLNL even tested several Uranium-Hydride bombs in the 1950s. Even though their computer models said the devices should explode, none gave a nuclear yield. One could use the waste from the reactor as a Radiological Weapon, but the reactor itself is not useful as a weapon.
The meaning of the word nuclear weapon, is a weapon that has a nuclear warhead on it.
Uranium 235, or plutonium, depending on weapon design
Nuclear surety, nuclear weapon design, positive release orders, civilian control, physical and procedural checks, and nuclear reliability.
This nuclear weapon is called an atomic bomb or a nuclear bomb
Nuclear weapon detonations
If by "bomb" you mean a conventional explosive weapon, then the nuclear weapon is more powerful.
To draw; draw a weapon.
Energy can be conserved from a nuclear weapon by reducing the energy loss through inefficiencies in the weapon's design and by using advanced technologies to maximize the weapon's destructive power. Additionally, minimizing the size and weight of the weapon can improve its efficiency and conservation of energy.
