The fuel in a nuclear plant is uranium, which is a natural ore found in the ground. Unlike coal, gas and oil, we don't burn uranium in a nuclear power plant.
Water is heated by fission in the reactor.
We then transfer this heat to make steam. The steam drives the turbines that generate electricity. Water used in the reactor and most other plant systems is piped in from the Miami-Dade water supply. We then purify the water at the plant to reduce mineral deposits that could otherwise reduce equipment efficiency and we test the water quality routinely in the plant's on-site laboratory. A separate supply of water that cools used steam for reuse comes from a unique, closed system of 36 interconnected canals.
