Abstract
Potential radiological consequences from sabotage attack on spent fuel casks are mainly determined by the quantity and size distribution of radioactive particulate matter released after penetration of the cask wall and of spent fuel elements. On behalf of the German Federal Ministry for the Environment, Nature Conservation and Reactor Safety full scale experiments of shaped charge attack on a Castor type spent fuel cask filled with 9 dry fuel elements of depleted unirradiated U02 have been conducted in a special facility in France in 1992 in order to review and establish requirements concerning physical protection. The arrangement of a vented chamber around the penetration hole enabled a complete collection of released particles. The mass of released particulate matter as function of the aerodynamic equivalent diameter (AED) has been measured for the size range
