☆☆☆☆☆Definition: energy from nuclear fission or fusion: the energy released by nuclear fission or fusion
Nuclear fission happens naturally every day.as uranium constantly undergoes spontaneous fission very slowly and emits fission products and neutrons. The uranium-239 isotope in natural uranium normally limits this reaction by capturing these neutrons before they could cause additional fissions of uranium-235 isotopes, preventing a chain reaction.
This process can be accelerated in a nuclear reactor by use of a moderator to rapidly slow the neutrons and thus increase the probability that they will trigger other fissions (instead of being captured by uranium-239 first), by participating in a chain reaction.
This process can be accelerated in an atomic bomb by enriching the uranium to between 20% to 95% uranium-235 isotope to increase the probability that they will trigger other fissions (instead of being captured by uranium-239 first), by participating in a chain reaction.
The half-life of the radioactive material.
As both fuels undergo reactions, heat is released, which is used to do work.
Uranium-235
Hydrogen is more available than uranium-235.
The biggest issue associated with nuclear power is determining what can be done with the radioactive waste.
