Abstract: DESCRIPTIVE ABSTRACT            For taking liquid samples, such as active solutions in an irradiated nuclear fuel processing plant within a confined area (10) located below a protective slab (12), use is made of vacuum pots (44), which are pneumatically transferred into a vessel (14) located beneath the slab and which are engaged on needles (40) supplied with fluid to be sampled and projecting into the bottom of the vessel.  A pot (44) is moved pneumatically into a nacelle, pod or basket (76) of a rotary drum (72) by means of a transfer duct (60), which passes through a slab element (62) installed in a rotary plug (20).  The positioning of the pot vertically with respect to a needle (40) is ensured by the combined rotations of the drum (72) and the plug (20). A vertical displacement of the slab element (62) ensures the sampling before the filled pot is pneumatically evacuated by the reverse path.            (Fig. 2)
