WebJul 12, 2024 · Uranium is the most widely used fuel by nuclear power plants for nuclear fission. Nuclear power plants use a certain type of uranium—U-235—as fuel because its atoms are easily split apart. Although uranium is about 100 times more common than silver, U-235 is relatively rare at just over 0.7% of natural uranium. WebU-235 is the main fissile isotope of uranium. Natural uranium contains 0.7% of the U-235 isotope.
