Difference Between PWR and BWR | Compare the Difference

We know that the temperature of boiling water increases if it is covered by a lid. There is a pressurizing unit in a PWR that keeps water that is flowing in the reactor under very high pressure so as to prevent it from boiling. This hot water gets converted into steam in the steam generator and then goes into the turbine to produce electricity.
