A nuclear power plant refers to a facility that converts nuclear energy into electrical energy through appropriate devices. Nuclear power plants use nuclear reactors instead of boilers in thermal power plants. Nuclear fuel burns in a special form in the nuclear reactors to generate heat, so that nuclear energy can be converted into heat energy to heat water and generate steam. The systems and equipment of nuclear power plants are usually composed of two parts: nuclear systems and equipment, also known as nuclear islands; Conventional systems and equipment, also known as conventional islands.
