Demonstrates how the nuclear steam supply system generates steam in a pressurized water reactor (PWR). (Click the Download File link to see in full view >>>>)

Coolant Light water is used as the primary coolant in a PWR. It enters the bottom of the reactor core at about 275 °C (530 °F) and is heated as it flows upwards through the reactor core to a temperature of about 315 °C (600 °F). The water remains liquid despite the high temperature...

The PWR cooling system is provided in order to circulate the reactor coolant heated with the thermal energy generated in a reactor core and to generate high-energy steam by conducting heat exchange at a steam generator to drive a turbine, and has the following functions; To circulate the reactor...

(1) Power control method As the reactor coolant (primary coolant) of PWR maintains the high-pressure of 157 kg/cm2 over the entire region of the flow path with the pressurizer, boiling would not occur in the reactor core even if the power fluctuates, and the liquid phase is kept. Therefore, since...

A pressurized-water-type nuclear power reactor (PWR) uses light water as the reactor coolant and moderator in the state of high temperature and high pressure not boiling in the reactor core (primary system: reactor coolant system) and sends the high-temperature and high-pressure water to steam generators...

Containment Isolation Containment isolation is provided to prevent or limit the escape of fission products that may result from postulated accidents. In the event of an accident, the containment isolation provisions are designed so that fluid lines penetrating the containment boundary are isolated...

The PWR consists of a primary system (reactor system) and a secondary system (steam system) in order to keep radioactive materials in the primary system. The reactor coolant in a reactor vessel (reactor coolant) of the primary system is pressurized so that it circulates with reactor coolant pumps without...

I think Calvert Cliffs Unit 2 still has the US Record of 693 Days !
