A nuclear power station is a facility that generates electricity by using nuclear reactions. These reactions typically involve the splitting of atoms, a process known as fission. The heat produced from fission is used to convert water into steam, which then drives turbines connected to generators. Nuclear power stations are designed with multiple safety systems to prevent accidents and protect the environment. They produce a significant amount of electricity with low greenhouse gas emissions, making them an important part of the energy mix in many countries. However, they also generate nuclear waste, which requires careful management and disposal.
