The invention relates to an apparatus for sampling a liquid conveyed by a plurality of tubes. The sampling apparatus comprises a cylindrical enclosure with a vertical axis and a circular cross-section having a given length. The enclosure has a lower planar wall, a side wall and a cover which seals the upper part of the enclosure. One of the walls is perforated by a plurality of orifices whose number is at least equal to the number of tubes. The end of each tube issues into one of the orifices which are regularly disposed along a portion of a single curve without a double point. The length of this curve portion exceeds that of the given length. The sampling device also comprises a movable sampling member in the form of a single suction tube having a free end associated with means for simultaneously rotating the suction tube about the axis of the enclosure and for translating the tube in such a way that its free end remains in contact with the wall provided with orifices and moves along the curve. A particular application is to a system for locating breaks in the jacket of a reactor, particularly a liquid sodium-cooled reactor.
An apparatus for sampling a liquid in a plurality of tubes wherein it comprises a cylindrical enclosure with a vertical axis and circular cross-section having a given length l, said enclosure having a lower planar wall, a side wall and a cover which scales the upper part of the enclosure, the lower planar wall being perforated by a plurality of orifices whose number is at least equal to the number of tubes, the end of each tube issuing into one of the orifices, the orifices being regularly disposed on a spiral marked on the lower planar wall, and a movable sampling member comprising a single suction tube having a free end associated with means for simultaneously rotating the suction tube about the axis of the enclosure and translating the tube in such a way that its free end remains in contact with the wall provided with orifices and moves along the curve.
