Facilities and Experience on Impact Test of Packages for Radioactive Materials Transport

According to the requirements of Chinese GB11806 and IAEA’s SSR-6, the packages for radioactive materials transport shall be tested to demonstrate the ability to withstand transport accidents. A small facility and a large one for package impact test have been designed and constructed to conduct the free drop test I experiment required in the GB11806 and SSR-6. The target of the smaller facility is a reinforced concrete component with volume of 3800mm × 3550mm × 3500mm. It is riveted by steel plate marked Q460 with volume of 3500mm × 3250mm × 100mm at surface. Total mass of the target is about 130t. The hoisting facility is mobile crane. The facility is used for the impact test of package within 13t. The target of the larger facility is a reinforced concrete component with volume of 11000mm × 7350mm × 7000mm. Steel plate marked Q460 with a volume of 11000mm × 5380mm × 100mm was anchored at concrete component top. Total mass of the target is about 1400t. The maximum height of the lifting hook in tower is 17.1m. The larger facility is used for the impact test of package within 130t. The two facilities for package impact test are both equipped with acceleration and stress measuring system, image measuring instrument, and geometrical measuring system. These two facilities have been used to conduct a lot of impact test of small packages weighing less than 12t. Some experience in construction and experiment has been concluded.
