May 19, 2025 · Nuclear reactors are the heart of a nuclear power plant. They contain and control nuclear chain reactions that produce heat through a physical process called fission.

A nuclear reactor is a device used to sustain a controlled fission nuclear chain reaction. They are used for commercial electricity, marine propulsion, weapons production and research. Fissile …

A nuclear reactor is driven by the splitting of atoms, a process called fission, where a particle (a ‘neutron’) is fired at an atom, which then fissions into two smaller atoms and some additional …

Jul 4, 2025 · Nuclear reactors work by keeping up a controlled chain reaction. When a powerful atom, such as uranium-235, gets a neutron, it decays into small nuclei and produces heat plus …

Nov 11, 2025 · How does a nuclear power plant work? Inside nuclear power plants, nuclear reactors and their equipment contain and control the chain reactions, most commonly fuelled …

Nuclear plants are different because they do not burn anything to create steam. Instead, they split uranium atoms in a process called fission. As a result, unlike other energy sources, nuclear …

Inside a nuclear power plant is a nuclear reactor where heavy elements, like plutonium or uranium, fuel nuclear fission reactions. These elements are contained in fuel rods. The fuel …

Sep 5, 2023 · Nuclear reactors generate energy through nuclear fission, where atomic nuclei split, releasing heat to produce steam that drives turbines for electricity.

HOW DOES A REACTOR WORK? Nuclear reactors produce energy through fission, the process of splitting atoms. Fission occurs when a neutron strikes a larger atom, causing it to split into …

Nuclear reactors produce heat by splitting atoms. This heat converts water into steam, which in turn turns a turbine that spins a magnet, causing electricity to flow to the grid.
