A pressurized water reactor includes 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 includes, along the direction of flow of the primary reactor coolant, a letdown line, a high-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 includes a hydrogenation system with a hydrogen supply and a hydrogen feeding line. In order to achieve efficient and fast hydrogen injection into the primary reactor coolant, a high-pressure feeding pump is arranged in the feeding line to provide a gas pressure higher than the discharge pressure of the charging pump. The feeding line discharges into the charging line.

Hydrogenation system for a pressurized water reactor

A nuclear power plant includes a nuclear reactor and a reactor coolant circuit containing a reactor coolant. The nuclear power plant further includes a degasification system () for the reactor coolant. The degasification system () is an ultrasonic degasification system comprising a sonotrode cluster () with at least one sonotrode () arranged in a line of the reactor coolant circuit or in a line which is fluidically connected to the reactor coolant circuit.
