As nuclear industries, such as fabrication of nuclear fuel and operation of nuclear power plants, are growing in the energy supplying system, the international society requires transparency in nuclear activities. In accordance in this matter, the analysis of environmental sample plays important role in nuclear safeguards, and monitoring nuclear activities in neighboring countries. KAERI has initiated a demanding systematic development of the analytical techniques for environmental samples and swipe samples. Bulk and particle sample analyses are two major analytical processes in determining the contents as well as isotopic information from the environmental samples. The samples for bulk analysis require chemical preparation consisting of ashing, acid digestion, and chemical separation while particle screening and transferring are necessary for particle analysis. Measurements using mass spectrometer such as induced coupled plasma mass spectrometer (ICP-MS) and thermal ionization mass spectrometer (TIMS) are followed for quantification and isotopic ratio analysis. This paper presented a discussion regarding the general procedure in systematic development of the related analytical technology along with some of the results from the bulk analysis.
