Nuclear Energy Vs. Fossil Fuel | Sciencing
Fossil Fuel. Nuclear energy comes from the energy stored in the nucleus (core) of an atom. This energy is released through fission (splitting atoms) or fusion (merging of atoms to form a larger atom). The energy released can be used to generate electricity. Fossil fuels—which mainly include coal, oil and natural gas—fill the majority …

Nuclear Fuel
Nuclear Fuel. Uranium is an abundant metal and is full of energy: One uranium fuel pellet creates as much energy as one ton of coal, 149 gallons of oil or 17,000 cubic feet of natural gas. It does not come out of the ground ready to go into a reactor, though. It is mined and processed to create nuclear fuel.

Fuel Assembly | Description & Components
Common nuclear reactors use enriched uranium and plutonium as fuel. Generally, there are two types of nuclear fuel cycles (for PWRs ): Uranium fuel cycle. Uses an enriched uranium fuel (~4% of U-235) as a fresh fuel. During the fuel burning, the content of the U-235 decreases, and the content of the plutonium increases (up to ~1% of Pu ).

Nuclear Fission | Understand Energy Learning Hub
Nuclear fission is the process of splitting a large atom into two smaller atoms and releasing a LOT of heat. That heat is used to boil water, make steam, turn a turbine and generator, and produce electricity. Most nuclear power plants today are fueled by enriched uranium 235 to produce non-renewable, carbon-free, 24/7 electricity.

Nuclear Fuel Cycle | Department of Energy
Generation of electricity in a nuclear reactor is similar to a coal-fired steam station. The difference is the source of heat. Fissioning, or splitting, of uranium atoms produces energy in the same way burning coal, gas, or oil is used as a source of heat in fossil fuel power plants. The fuel used in nuclear generation is 235 U and/or 239 Pu.

What is Nuclear Fuel? | NRC.gov
It is an "isotope," or an atom with a very specific number of neutrons, known as U-235. Part of the process of turning uranium ore into nuclear fuel is enrichment—which increases the amount of U-235 relative to the other isotopes naturally found in uranium. Under the right conditions in a reactor, neutrons will cause U-235 atoms to fission ...

Spent Fuel Handling – Storage of Spent Nuclear Fuel
In nuclear power plants, spent nuclear fuel is stored underwater in the spent fuel pool on the plant. Plant personnel moves the spent fuel underwater from the reactor to the pool. Over time, as the spent fuel is stored in the pool, it becomes cooler as the radioactivity decays away. After several years (> 5 years), decay heat decreases under ...
