[en] Chemical analyses were carried out through this project from January 1st to December 31th of 2008 for the 9,656 cases from the nuclear R and D projects, from the facilities of nuclear fuel cycle examination and from the domestic nuclear industries such as nuclear power plants(KEPCO), fuel producing company(KNFC). The nuclear analytical service was conducted for the determination of nuclear speciation, isotope ratio, elemental analysis, and nuclear analysis in radioactive samples. Their results were recorded as an accreditation report. Meanwhile, the methodology for representative sampling has been developed by systematical classification of the KAERI radwastes to analyze chemically the main alpha and beta emitting radionuclides. The procedures of chemical radionuclides assay have been prepared to identify the radionuclide concentrations in the KAERI LILW drums. Eventually, data base for the results of radiochemical analysis was established
