Comparision between Nuclear Power Plant and Nuclear Bomb

Entities	Power Plant	Nuclear Bomb
Uranium Enrichment	3-5% of enrichment	More than 90% of enrichment
Reaction	Controlled Chain Reaction Using Control Rods	Uncontrolled Chain reaction without any usage of control rod. Reaction is fast and spontaneous.
	When the reactor is turned on, the multiplication of fissions is allowed to continue until the reactor is generating power at the desired rate. Then control rods that absorb neutrons are inserted until exactly one neutron from each fission causes another fission.	Two neutrons produced by fission was absorbed by an atom of U-235 the number of fissions would double in a fraction of second and then double again and again. If this were allowed to continue, in a few seconds the power produced is enough to melt a reactor.
