A pressurized water reactor (PWR) consists of two coolant systems to convert the heat originates from fission process into electrical power. The primary system pumps the not boiling light water (coolant and neutron moderator), in the state of high temperature and high pressure, to the steam generator where it transfers thermal energy to the secondary system via heat transfer processes. The steam generated flows to turbines to generate electricity, and passes through the main condenser and become cool water. The water is then pumped back to the steam generator and forms a cycle. In real applications, there are around one hundred support systems to assure the two systems function properly. In addition, special systems are designed to combat with emergencies.
