EVALUATION OF SAFE1Y OF CASKS IMPACTING DIFFERENT TYPES OF TARGETS

The paper presents results of the Phase 1 investigations of the joint German-UK research project \"Evaluation of Safety of Casks Impacting Different Kinds of Targets\" funded by the European Commission in order to improve safety and acceptance of radioactive materials transport. In addition to a literature survey concerning real target drop tests with Type B casks performed all over the world, the Phase 1 investigations had the primary objective to compare the loads of the casks during drops onto real (yielding) targets with those existing under IAEA test conditions. The paper gives a short description of the methodologic basis of these analyses and discusses first results. Because the project will be completed March 1998, only preliminary conclusions can be given in this written version (submission date October 1997). The oral presentation at the conference will cover the final results of the project.
