Method of and apparatus for introducing gas into the coolant liquid of nuclear reactors.

摘要

In a method of and apparatus for injecting gas into a liquid, in particular the reactor core coolant water for a pressurised water nuclear power reactor system, only the gas quantity needed to achieve a predetermined gas concentration in the liquid is supplied, via a gas dosage pump (1), to nozzles (5, 5a) within a bubble chamber (6). The liquid also is supplied to the bubble column (6), via an inlet (20). A mixture of the gas and water flows through static mixers (7) in the bubble column (6) to produce the desired gas concentration in the liquid, mixing taking place before the gas and liquid leave the bubble column.
