Nuclear reactors cannot explode like nuclear weapons because they utilize low-enriched uranium that cannot achieve the rapid supercritical geometry required for a nuclear detonation.
The claim that commercial nuclear power plant reactors cannot explode like nuclear weapons is a well-established physical fact regarding reactor physics and fuel enrichment limitations. None of the retrieved papers directly address or study the physical impossibility of nuclear weapons-style detonations in power reactors, as this is foundational nuclear engineering knowledge not requiring current citation.
