The clearance level verification evaluation system (CLEVES) has been developed to execute clearance activities efficiently. The SNM which is one of programs of the CLEVES was fabricated for selecting nuclides for measurement and assessment (NMA) based on evaluation of relative importance measure (RIM: nuclide activity divided by clearance level) for nuclides. In addition, case study was carried out by using the SNM based on data concerning clearance activities for concrete generated from the JRR-3. In this report, outline of the CLEVES, a method for selecting NMAs in the SNM, and calculated results of case study are described.
