Question

Which Uranium isotope is used in nuclear power plants to produce electricity ?; 1) U-233; 2) U-234; 3) U-238; 4) U-239

Answer 1

Uranium-233 is made from thorium-232 by neutron bombardment. The isotope uranium-235 is important for both nuclear reactors and nuclear weapons because it is the only isotope existing in nature to any appreciable extent that is fissile, that is, can be broken apart by thermal neutrons.
