Abstract
PURPOSE: To enable a vacuum pump to be protected from the contamination, by means of enabling the sampling of a reactor water from a plurality of sampling tubes by one vacuum pump, and of subjecting not of exceed over the upper limit by regulating the level of the absorbed level of reactor water.
CONSTITUTION: For the sampling of the sample of reactor water, all of the valves at for this device, are first closed, and then the inner reactor water is pushed down, up to the tops of fuel assemblies 22W25 being appeared into air from the reactor water, by means of sending compressed air from an air introducing tube by covering a shipper cap 18 to the fuel assemblies 22W25 of the inspective objects, and of opening an air supplying valve 20. Then, the reactor water within the fuel assemblies 22W25 are absorbed into sampling tubes 1W4 by meand of closing the air suppluying tubes 20, of opening sampling valves 26W29, an air absorbing tube 32, and a valve 45, and of driving a vacuum pump 31. Thereafter, the samples at a constant quantity are taken out from taken out ports 9W12 by means of holding the reactor water at B-B line by stopping the vacuum pump 31, of closing the valve 45, and of opening a valve 43 and valves 37W40.
