A plurality of sampling tubes are connected with a selector valve and the selector valve selects one of the sampling tubes so that the sample gas is lead through the selected sampling tube and a pipe way downstream of the selector valve to a leakage detection system. The pipe way is provided with a gas flushing section for flushing with high pressure gas and the gas flushing operation is performed before each change-over of the selector valve. The flow of sucked gas is kept constant by providing a gas flow control device downstream of the leakage detecti...
1. A sodium leakage detection system comprising: at least one sodium flow path; a plurality of first sampling tubes for sampling surrounding gas at various points along said at least one sodium flow path and for conducting gas samples obtained at said various points away from said flow path; a selector valve located at the gas exit ends of said plurality of first sampling tubes for selectively connecting one of said gas exit ends of said first sampling tubes with a second sampling tube; said second sampling tube being connected to said selector val...
