SAMPLING APPARATUS OF LIQUID RADIOACTIVE WASTE FROM STORAGE CAPACITIES ON ATOMIC POWER STATION Russian patent published in 2009 - IPC G01N1/14 

FIELD: physics; measuring.

SUBSTANCE: invention concerns to the device for sampling of a fluid and can be used in atomic engineering for the control of a state of the liquid radioactive waste stored on territory of the atomic power station, and also can be used in chemical industry by operation with aggressive liquids. The sampling apparatus of a liquid radioactive waste (LRW) from storage capacities on the atomic power station contains vertically moving massive sampler with outside holes and the interior offtaking channel which is connected by means of a flexible sampling hose with a sampling vessel. The sampling apparatus contains also the vacuum pump connected to the sampling vessel, a resort of fixing of depth of dip sampler in LRW, pipelines and gates for realisation of auxiliary and working sampling/sample selection operations. The sampling apparatus is equipped by the gadget for deactivation and wash of an interior surface of a flexible hose and the interior offtaking channel of the sampler. Thus it is supplied by the hermetic portable cabinet for arrangement of a reserve of the flexible sampling hose which by means of tube drifting, having the mobile trace of the flexible sampling hose, is joined through a vertical branch pipe to an upper of capacity for LRW storage. The vertical branch pipe of penetration piping is equipped by the gadget for deactivation and wash of an outside surface of the flexible hose and the sampler.

EFFECT: decrease of labor input at the expense of reduction of action of radiation at the offered arrangement of knots of the device.
