Method and sampling system for recovering a sample from the atmosphere in a reactor containment of a nuclear facility

摘要

A sampling system (1) for recovering a sample from the atmosphere in a reactor containment (2) of a nuclear facility with a sampling line (8) connected to a vacuum system (12) and to an analysis system (14) opening into the reactor containment (2) make it possible to provide a sample suitable for determining particularly reliable and accurate measured values for gas contents of the containment atmosphere. For this purpose, the sampling line (8) according to the invention on the gas side connected in connection with the atmosphere in the reactor safety container (2) upstream of a throttle device (30). This allows the sample to be transferred from the reactor containment vessel (2) to the analysis system (14) in superheated condition.
