PURPOSE:To prevent a radioactive substance from leaking while improving reliability by lessening contamination of sample water, by automatizing the operation of manufacturing a radioactivity measuring sample by supplying the sample water of unclear-reactor cooling water to an ion-exchange resin column. CONSTITUTION:An equipment for supplying sample water to an ion-exchange resin is composed of ion-exchange resin column 6, adaptor 7 holding the column, traveling body 8 inserted the adaptor to travel, traveling-body driving mechanism 9, injection nozzle support body 2 having injection nozzle 3 injecting the sample water into the ion-exchange resin column and piping 4 cleaning the injection nozzle, receptacle 10 for the sample water from column, liquid level gauge 27, gas purging piping 28, etc. As a result, it never comes into contact with the sample water adaptor and part of the sample water receptacle and only the inside surface of nozzle 4 requires washing after processing; even if the adaptor shifts from its set position, there is no problem as to the operation of the equipment and no probability of leakage. |
