摘要：

An experiment termed "Q-PETE" representative for the situation in the Helium Cooled Pebble Bed (HCPB) breeding zone and suitable for the validation of relevant tritium transport codes has been devised. In a temperature controlled setup a hydrogen loaded gas is directed over a steel membrane (several millimeter thickness) into which it can permeate. On the other side of the membrane a sweep gas flow collects the permeated hydrogen and transports it to a quadrupole mass spectrometer for quantitative time resolved detection. This paper introduces methods to handle time resolved permeation experiments with sweep gas, considering the residence time distribution of the sweep gas. The methods are used to quantitatively simulate the planned experiments and expected signal distortion effects. Additionally, an uncertainty model is applied to find optimized process- and geometry parameters for the experiments.
