Can the Atomic reactor explode like an Atom Bomb?
Atomic bomb uses 100% U235 or Pu239 whereas in the reactors either it is natural Uranium which contains only 0.7% U235 or enriched Uranium of 1.5% to 4.5% enrichment. The effort in the bomb is to generate maximum energy in the smallest possible time there by resulting in the explosion. Whereas in the reactor the effort is to generate rated power on a continuing basis. So various controls are put to ensure that the power generated is within its capacity at all times. Thus design of nuclear reactor does not permit such explosion.
