A condensation vessel for the measurement of steam pressure includes a steam zone, a steam line which opens in the steam zone at an entrance, a condensate zone which is directly adjacent the steam zone and geodetically below the entrance, and a discharge device which is connected to the steam zone and which serves for a discharge of steam and noncondensable gases from the condensation vessel. A method for operating the condensation vessel includes condensing steam which contains an increased fraction of a noncondensable gas, in particular radiolysis gas, out of the steam zone. The gas is led out of the condensation vessel in dissolved form through the discharge device, with the result that the risk of faulty measurement is largely ruled out, since virtually no gas is dissolved in the condensate within the condensate zone. The condensation vessel can be installed in a simple way, even in the course of retrofitting, for measuring the filling level of a reactor pressure vessel./!
