Test procedure with a 15, 000 Kg half-scale prototype of transport and storage cask - 59141

Document available in abstract form only. Full text of publication follows: BAM is the competent authority for mechanical and thermal safety assessment of transport packages for spent fuel and high level waste in Germany. In context with the package design approval procedure for transport and storage of new German cask several drop test series were performed by BAM with a half-scale prototype. The test program comprised a sequence of a total of 18 drop tests with different drop orientations, drop heights and temperatures. The sequence of testing in the program consisted of a number of nine-meter free drop onto an unyielding target and several drops from one meter onto a steel puncture bar. In order to cause maximum damage on the package various drop orientations were performed according to the most severe drop position as well as most sensitive parts of the container. The subsequent release of radioactive substances must not exceed a value specified in the dangerous goods transport regulations. Radiation shielding and nuclear safety has to be guaranteed. The prototype was tested under normal and accident conditions of transport in the 200 tons BAM drop test facility at BAM Test Site Technical Safety. Extensive test methods as well as comprehensive measurement data are presented within the complexity of performed drop test procedures. (author)
