The European Network of Testing Facilities for the Quality Checking of Radioactive Waste Packages (ENTRAP) initiated a feasibility study on how to organize in the most cost effective way an international proficiency tests for non-destructive, gamma-ray based, assay of 220 liter radioactive waste drums in the European Union at a regular time interval of 2 or 3 years. This feasibility study addresses all aspects of proficiency testing on radioactive waste packages including the design of a commonly accepted reference 220 liter drum. This design, based on the international response on a send out questionnaire, includes matrixes, radioactive sources; a solution to overcome the tedious and expensive international transport costs of real or even simulated waste packages, general cost estimation for the organization of, and the participation in the proficiency test. The proposed concept for the proficiency testing and the estimated costs are presented. The participation costs of the first proficiency test are mainly determined by the manufacturing of the non-radioactive 220 liter drum ({+-} 55%). Applied reference sources, transport of the drum and reference sources and participation costs in the proficiency test contribute each about {+-} 15%. (authors)
