1. A pressurized water reactor comprising:
a primary reactor coolant circuit flown through by a primary reactor coolant during operation; and
a chemical and volume control system for the primary reactor coolant, the chemical and volume control system comprising, along the direction of flow of the primary reactor coolant, a letdown line, a pressure charging pump with a given discharge pressure, and a charging line leading to the primary reactor coolant circuit, the chemical and volume control system further comprising a hydrogenation system with a hydrogen supply and a hydrogen feeding line, a pressure feeding pump being arranged in the hydrogen feeding line to provide a gas pressure higher than the discharge pressure of the pressure charging pump, the hydrogen feeding line discharging into the charging line, a heat exchanger, configured to be flown through by a heating medium, being arranged in the charging line to increase the temperature of the primary reactor coolant before injection into the primary reactor coolant circuit, a connection between the hydrogen feeding line and the charging line being located in a section of the charging line between the charging pump and the heat exchanger.
