Abstract
The present status of JAERI’s project to establish analytical techniques mainly for safeguards environmental sample s is described. So far, the essential analytical techniques were established, at CLEAR, for ultra-trace amounts of uranium and plutonium. In addition, similar analytical techniques applicable to hot-cell swipe samples have been developed at NUCEF. In January 2003, JAERI was qualified as a member of the IAEA network-analytical laboratories for the environmental samples. Hence the second phase of the project has just started to develop more advanced techniques. This paper deals with recent topics on facility characteristics of CLEAR, the techniques developed for bulk, particle and hot-cell sample analyses, and some applications of the techniques.
