nuclear power type

Nuclear fuel - Wikipedia

Nuclear fuel is material used in nuclear power stations to produce heat to power turbines.Heat is created when nuclear fuel undergoes nuclear fission.. Most nuclear fuels contain heavy fissile actinide elements that are capable of undergoing and sustaining nuclear fission.The three most relevant fissile isotopes are Uranium-233, Uranium-235 and Plutonium-239.

Why is Uranium-235 ideal for nuclear power? | HowStuffWorks

Nuclear fission occurs when one atom splits into two, creating energy. Spontaneous fission occurs all the time. Uranium undergoes spontaneous fission at a very slow rate, and emits radiation. Uranium-235 (U-235) is only found in about 0.7 percent of uranium found naturally, but it is well-suited for producing nuclear power.

Nuclear energy is the energy in the nucleus, or core, of an atom. Atoms are tiny units that make up all matter in the universe, and energy is what holds the nucleus together. There is a huge amount of energy in an atom's dense nucleus. In fact, the power that holds the nucleus together is officially called the "strong force."Nuclear energy can be used to create electricity, but it must first ...
