Answers
Answer:
Nonrenewable Energy Resources
Nuclear Fuel
Nuclear fuel—Uranium-235, found in certain rock formations, is mined for use as the fissile material in slow-reaction nuclear power generation. Rare in its natural state, uranium-235 is a nonrenewable resource, although small quantities go a long way. For example, the fission of one pound of uranium releases more energy than burning three million pounds of coal.
In fast-reaction nuclear power generation (breeder reactors), high-velocity neutrons cause the fissions, using plutonium or uranium-233. Breeder reactors produce more fuel (enriched uranium and plutonium) than they consume. Thus, fast-reaction nuclear power fuel is considered renewable and sustainable. Nuclear power plants do not release carbon dioxide (a contributor to global climate change) or sulfur dioxide (a contributor to acid rain).
