Why can a nuclear power plant not explode like a nuclear bomb?
Can the reactor explode? Fortunately, the reactor cannot explode. A nuclear explosion cannot occur because the fuel is not compact enough to allow an uncontrolled chain reaction. The MIT reactor has a lot of water and core structural materials that slow the neutrons down before they reach other fissile atoms.
Do nuclear power plants produce material that could be converted into nuclear weapons?
LEU is not directly usable for weapons. HEU produced for weapons (“weapon-grade” uranium) is typically enriched to 90 percent uranium-235 or greater, but all HEU can be used to make nuclear weapons….Fissile materials basics.

Why uranium 235 and uranium 238 are used in nuclear power plants is it safe to use?
All isotopes of uranium are unstable and radioactive, but uranium 238 and uranium 235 have half-lives which are sufficiently long to have allowed them to still be present in the Solar System and indeed on Earth.
What does it mean to enrich uranium and why is that necessary for a nuclear reactor?
Enriching Uranium The nuclear fuel used in a nuclear reactor needs to have a higher concentration of the U235 isotope than that which exists in natural uranium ore. Under controlled conditions, these extra neutrons can cause additional, nearby atoms to fission and a nuclear reaction can be sustained.
How do nuclear power plants create energy?
Nuclear power plants heat water to produce steam. The steam is used to spin large turbines that generate electricity. Nuclear power plants use heat produced during nuclear fission to heat water. In nuclear fission, atoms are split apart to form smaller atoms, releasing energy.
What is nuclear material used for?
Medical, Industrial, and Academic Uses of Nuclear Material. Uranium Recovery Facilities. Fuel Cycle Facilities. Materials Transportation.
Why is uranium enrichment necessary?
The purpose of uranium enrichment is to increase the percentage of the uranium-235 isotope with respect to others, with a necessary percentage of around 4\% for light water reactors.
