Abstract:
1. A combination of a reactor containment of a nuclear plant and a sampling system for taking a sample from an atmosphere in the reactor containment of the nuclear plant, the sampling system comprising: a sampling line having an end opening into the reactor containment; a vacuum system connected to said sampling line; an analysis system connected to said sampling line; and a restriction device including a throttle located in the reactor containment at said end of said sampling line for connection to the atmosphere in the reactor containment, said restriction device configured to preclude condensation of the sample by maintaining a vacuum state while the sample is transported from said restriction device to said analysis system in said sampling line; wherein said sampling line is a capillary line with a nominal width of about 1 to 5 mm, and said restriction device has a free flow cross section of 0.05 to 2 mm.
