Nuclear power stations generate electricity through the fission, or splitting, of uranium atoms inside the reactor core, which generates extreme amounts of heat. The core is surrounded with water, which boils due to the heat, creating steam that is then used to drive a turbine to create electricity.
This same type of steam turbine is also used in fossil fuel-burning power plants, with the only major difference being the source of the heat that creates the steam.
In nuclear power plants, there are two different ways to generate the steam. The first is a boiling water reactor, where steam is created directly within the reactor and then carried to the turbine through pipes. The other method is the pressurized water reactor, where the heated water surrounding the reactor is kept under intense pressure to prevent it from boiling. After reaching a specific temperature, the heated water is then transferred to a secondary container near the turbine, where it is then allowed to boil and create steam.
There are approximately 100 nuclear power stations in the United States. Nearly two-thirds of those are pressurized steam reactors. Despite the small number of nuclear power plants, nuclear energy accounts for around 20 percent of the country's total electricity output.Learn More

What is often referred to as "the theory of relativity" is actually two theories, general and special, that describe the way the universe works on its largest scale and at its highest energies. The three main premises of the theories are that matter and energy are interchangeable, space and time are difficult to distinguish in calculations and no frame of reference is better for viewing the universe than any other.Full Answer >
Albert Einstein studied physics. He became famous for developing the theory of relativity and for conducting extensive research on the Brownian movement of molecules and the thermal properties of light. In 1921, he received the Nobel Prize in Physics.Full Answer >
