CONDENSATION VESSEL FOR STEAM PRESSURE MEASUREMENTS, USE OF THIS CONDENSATION VESSEL FOR LEVEL AND STEAM FLOW RATE MEASUREMENTS, AND PROCESS FOR OPERATING A CONDENSATION VESSEL

摘要

A condensation vessel (1) for steam pressure measurements has a steam area (3), a steam duct (4) that opens at a mouth (5) into the steam area (3), a condensate area (6) that immediately follows the steam area and is geodesically arranged below the mouth, and a discharge device (7) in communication with the steam area (3) for discharging steam and non-condensable gasses from the condensation vessel (1). Steam containing an increased proportion of a non-condensable gas, in particular radiolysis gas, may be condensed from the steam area (3). The gas is discharged in a dissolved state from the condensation vessel (1) by the discharge device (7), largely excluding any risks of measurement errors, since practically no gas is dissolved in the condensate within the condensate area (6). The condensation vessel (1) may be easily built or retrofitted into a reactor pressure vessel for carrying out level measurements.
