Light Water Reactor

A Light Water Reactor (LWR) is a common type of nuclear power plant that generates electricity using nuclear fission. It uses ordinary water as both a coolant and a moderator to slow down neutrons, making the nuclear reaction more efficient. Inside the reactor, uranium fuel atoms split, releasing heat. This heat turns water into steam, which drives turbines connected to generators, producing electricity. LWRs are widely used due to their proven safety, efficiency, and the availability of water resources for operation. They are an essential part of many countries' energy infrastructure, providing a significant source of low-carbon electricity.
