Ydinvoimaloilla, or nuclear power plants, are facilities that harness nuclear reactions to generate electricity. The process typically involves nuclear fission, where heavy atomic nuclei, such as uranium, are split into lighter nuclei. This splitting releases a significant amount of energy in the form of heat. The heat is then used to boil water, creating steam. This steam drives turbines, which in turn power generators to produce electricity.

The core of a nuclear power plant contains the nuclear fuel, usually in the form of fuel rods. These rods are placed in a reactor vessel, where the controlled chain reaction of fission occurs. Control rods, made of materials that absorb neutrons, are used to regulate the rate of the nuclear reaction. Cooling systems are essential to manage the heat generated and prevent overheating.

Nuclear power is a low-carbon source of electricity, meaning it produces very little greenhouse gas emissions during operation. However, the process also generates radioactive waste, which requires careful management and long-term storage due to its potential hazards. Safety is a paramount concern in the design and operation of nuclear power plants, with multiple layers of protection and strict regulations in place to prevent accidents and protect both workers and the public. The decommissioning of old nuclear power plants also presents a significant challenge, involving the safe dismantling of the facility and disposal of radioactive materials.
