Abstract
A sampling system for taking a sample from the atmosphere in a reactor containment of a nuclear plant, includes a sampling line which is connected to a vacuum system and to an analysis system. The sampling line opens into the reactor containment and has a restriction device connected upstream thereof on the gas side for connection to the atmosphere in the reactor containment. A method for taking such a sample is also provided.
Claims27
A sampling system for taking a sample from the atmosphere in a reactor containment of a nuclear plant, the sampling system comprising:
- a sampling line 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 connected upstream of said sampling line on a gas side for connection to the atmosphere in the reactor containment.
A method for taking a sample from the atmosphere in a reactor containment of a nuclear plant, the method comprising the following steps:
- producing a vacuum in a sampling line, relative to a pressure prevailing in the reactor containment;
- and
- limiting the pressure in the sampling line to a maximum of about 60% of the pressure in the reactor containment after an inflow of a sample into the sampling line.
