pressurised water reactor
Power reactor where the heat is discharged from inside the reactor (so-called reactor core) via water which is under high pressure (about 160 bar). Thus boiling is avoided inside the reactor core and simultaneously a high water temperature is achieved in the reactor circuit (so-called primary coolant circuit).
The coolant of the primary coolant circuit gives off its heat in a steam generator to the water of the secondary coolant circuit. The steam generated in this way drives the turbine and the generator to generate electrical current.
