Nuclear Power Plants, Nuclear Energy

A nuclear power plant generates electricity using the heat released by nuclear fission, the splitting of heavy atomic nuclei. The fuel is most often uranium, whose nuclei can be split when struck by a neutron. Each fission releases energy and additional neutrons, which can split further nuclei in a self-sustaining chain reaction. The energy appears as heat, which the plant uses to make steam in much the same way a fossil-fuel station burns coal or gas.

The reactor is the heart of the plant. It contains the fuel, a moderator that slows neutrons so they can sustain the reaction in many common designs, and control rods made of neutron-absorbing material that are inserted or withdrawn to regulate the rate of fission. Coolant circulating through the core carries heat away; this heat boils water into steam, the steam spins a turbine connected to a generator, and the generator produces electricity. The steam is then condensed and returned, completing the cycle.

Nuclear power supplies a significant share of electricity in many countries and produces very little carbon dioxide during operation, which is a major reason for continued interest in it. Its drawbacks include the long-lived radioactive waste that must be safely stored, the high cost and complexity of building plants, and the need for strict safety measures to contain radioactive material. Multiple layers of containment and backup cooling are designed to prevent the release of radiation even if equipment fails.

Frequently asked questions

How does a nuclear power plant make electricity?: Nuclear fission heats water into steam, the steam drives a turbine connected to a generator, and the generator produces electricity.
What are control rods for?: They are made of neutron-absorbing material and are moved in or out of the reactor core to speed up, slow down or stop the chain reaction.
Does nuclear power emit carbon dioxide?: It releases very little during operation, though its main challenges are radioactive waste storage, high construction costs and safety.
