Equalizing reservoir configuration, especially for cooling circuits in nuclear power stations

摘要

An equalizing reservoir configuration for fluid circuits with volume and/or pressure fluctuations, especially for cooling circuits in nuclear power stations, includes an equalizing reservoir communicating with a fluid circuit through a fluid line connected to a base of the equalizing reservoir, so that a lower fluid chamber and an upper gas buffer chamber form in the equalizing reservoir. An upper end of an equalizing riser opens into the gas buffer chamber and runs out into a U-tube containing a water/air seal and being disposed beneath the equalizing reservoir. This provides a slim construction for narrow spaces and an increase in the air volume of the equalizing reservoir.
