Test installations for the examination of CASTOR casks at the BAM test centre technical safety
(2008)
BAM as competent German government institute for the mechanical and thermal testing of radioactive material transport and storage containers, operates unique drop and fire test facilities for experimental investigations on an open-air Test Centre Technical Safety.
To be able to perform even drop tests with full-scale spent fuel or HAW casks (i. e. the German CASTOR cask designs; CASTOR in the meantime in synonym for all other spent fuel cask designs) BAM constructed in 2004 a large drop test facility capable to handle 200 tons test objects, and to drop them onto a steel plate covered unyielding target with a mass of nearly 2600 tons. Drop testing of the 181 ton CONSTOR V/TC, the 127 ton MHI-MSF 69BG, a 1:2 scale model (CASTOR HAW TB2) and of cubic containers for radioactive waste disposal will briefly be presented. The experimental BAM drop testing activities can be supported also by drop testing of smaller packages (up to 2 tons) in an in-house test facility, and by dynamic, guided impact testing inside a new drop test machine. In May 2008 a new modern fire test facility was put into operation. The facility provides two test stands fired with liquid Propane. Testing in every case has to be completed by calculational investigations where BAM operates appropriate computer codes, e. g. ABAQUS, LS-Dyna, ANSYS and other analytical tools.
