摘要： PURPOSE:To supply surely filter papers and spacers by a method wherein the control for suction and supply of filter papers is carried out by providing a means for distinguishing between the filter paper and the spacer. CONSTITUTION:Four large and small holes are provided alternately on the circumference of a turntable 1 which is rotated by a driving means 8. Filter papers and spacers are placed alternately on a disk 11 equipped with a spring 12 within a paper supply container 2. The top of the filter paper or the spacer is pressed against a roller 10 by the spring 12. When the turntable 1 is rotated and a large hole is positioned above the container 2, a catching means 4 descends. A valve V5 is closed and a valve V3 is opened by a detector 9. When the detector 9 detects the spacer, the valve V5 is closed and a valve V4 is opened. By this operation, the filter paper or the spacer is attracted by the catching means 4. When the table 1 is rotated in a 90 deg. arc, the filter paper or the spacer drops into a smaller hole of the table 1. In case of the filter paper, filtration is carried out by the rotation in a subsequent 90 deg. arc. By further mext 90 deg. rotation, the filter paper is introduced into a container 3 by a pushing means 6.

摘要： PURPOSE:To prevent the contact between an injection nozzle and an ion exchange column and accordingly the leakage of a sample by using two nozzles having different internal diameters as tubes for injecting the liquid samples from a metering tank into the column. CONSTITUTION:A liquid sample flows through a valve 32 upwardly into a metering tank 3. When the tank 3 is filled up with the sample so that it flows out through flow switches 35 and a valve 36 into a drainage bath 37, the switch 35 detects this to generate signals. In response to these signals, the valves 32 and 33 are changed over. If the tube diameter of a nozzle 20 is small, the liquid sample is stored in the metering tank 3. When a valve 34 is opened to inject the sample into the ion exchange resin column, the sample is injected from one nozzle 5 or 20. Then, the liquid level in the column 12 is raised so that the sample will flow out until the inlet of the other nozzle is closed. Thus, it is possible to provide a device of high safety.

摘要： PURPOSE:To back-wash off the solid matters having attached to the surface of filter paper for ensuring the reuse of said filter paper and reducing exposure to radioactive rays. CONSTITUTION:After the completion of filtration, an upper tank 3 is raised slightly, and filter paper 1 is transferred and turned upside down and placed above the lower tank 22 of a washer 30 so that the upside thereof to which solid matters have attached comes down by means of a transfer mechanism 40. Next, sealing is made by bringing said filter 1 and said lower tank 22 in contact with each other with said upper tank 21 pressed down. Washing water is supplied to said upper tank 21 with a valve V20 opened, and the solid matters 8' having attached to said filter 1 are backwashed off into said lower tank 22 with the washing water from said upper tank 21 by operating a vacuum pump 6 with a valve 22 opened and valves V3 and V21 closed. Said filter paper 1 is shaped into an endless band.

摘要： PURPOSE:To enable the filter safely and easily to be treated by a method wherein a spent band filter is removed by remote control in a filtration apparatus using a band filter. CONSTITUTION:The spent band filter 8 is wound up by driving an electric motor 29. After winding up, the filter 8 drops into a container 37 provided below a winding drum 20 and is housed. The projections 23, 24 of a disk 22 fixed to the driving shaft of a motor 29 are inserted into the holes 25, 26 of the winding drum so the the winding drum 20 winds up the band filter by the rotation of the disk 22. The projections 23, 24 are detached from the holes 25, 26 in such a manner that another side of the winding drum is attracted by a magnetized arm 30 and an electrically- driven cylinder 33 connected to the arm 30 is moved right and left.

摘要： PURPOSE:To reduce the effect of the residue of radioactive sample water by a simple means, by a method wherein a plurality of systems of fixed-amount piping units are provided, and corresponding to the radioactive concentration, a fixed amount of radioactive sample water is transported to a piping system unit. CONSTITUTION:After sample water is taken into intake tank 2 by opening valve 1, its approximate concentration is measured by a radioactivity monitor provided on the outer side of the tank. Corresponding to the concentration, the sample water is sent to one of fixed-amount tanks 7, 11, 15, which constitute fixed-amount piping unit, through sample water transport pipe 16. When the concentration measured by the monitor is high, the sample water is sent to tank 7 by opening valve 5 on the side of arrow 30 and valve 4 on the side of arrow 31. When the sample water overflows, its supply to tank 7 is stopped by closing valve 4 by means of flow switch 6. By this, it is possible to greatly reduce the effect due to the residue of the radioactive sample water.

摘要： PURPOSE:To simply detect the outflow of a liquid by a method wherein a liquid level detector for an overflowing liquid in a storage container and a liquid-discharging pipe which has an orifice function provided on the liquid outflow side of the storage container are utilized. CONSTITUTION:A sample liquid is led to flow in through a guide pipe 6 and part of the liquid is discharged through an orifice, then the rest of the liquid flows in a storage container, but if the resistance of flow passage on the container side 8 is made smaller than that of the orifice 11, most part of the sample liquid flowed through the pipe 6 flows into the container 8. When a suitable amount of the liquid has flowed into the container, a floating type switch 9 operates and renders a signal from a signal line S. Since the sample liquid led to a fixed quantity tank 1 flows into it from a valve 3, the sample liquid does not flow into the container 8 if the valve 3 of the tank is operated to close by the signal from the signal line S. Therefore, the liquid in the container 8 is discharged through the orifice 11 and simultaneously the switch 9 is automatically reset. By this constitution, the existence or non-existence of the sample liquid can be detected, and the amount of overflowing liquid from the fixed quantity tank can be set without difficulty.

摘要： PURPOSE:To achieve higher speed of work by providing a plurality of sample water sampling devices and metering devices and using a cassette type sample water processor. CONSTITUTION:A plurality of pipings and pumps are provided to a sample water sampling device 3 which samples the atomic reactor water in fuel elements 1 and plural pipings with valves and metering tanks and provided to a metering device 4 which meters the sample water from the sample water sampling device 3 or atomic reactor water drawing port 2. Then, the reactor water in a plurality of the fuel elements 1 is simultaneously sampled and metered and is then sent into a sample water processor 5 consisting of a cassette mounted with membrane filters and ion exchange resin columns. The sample water processor 5 is moved by a moving device 8 to a sample exhange device 9, where the membrane filters or ion exhange resin columns are subsequently selected and are sent into a radioactivity measruing unit 10, whereby specified measurement is accomplished.
