Abstract
Low level radioactive solid wastes generating from nuclear power plant are classified into air and liquid-filter, articles of consumption, various parts of replacement and consumption materials generating during periodical inspections, and so on. Therefore it is difficult to define such wastes univocally, because waste forms and contamination conditions are different respectively.
In order to bury these wastes into a shallow land disposal site, it is necessary to understand waste properties, and to establish reasonable fabrication technology of waste package.
We sampled and discriminated representative wastes at the power plants, and determined specifications of simulative wastes. Then we made confirmation test of fabrication technology of waste package through making full-scale simulative packages experimentally on the basis of reasonable waste package classification in consideration of conformity to technical criteria, and we examined non-destructive radioactivity measurement for waste packages. This report describes the outline of these studies.
