THE FINITE ELEMENT METHOD FOR RETENTION SYSTEM OF RADIOACTIVE MATERIAL TRANSPORT PACKAGE

摘要

According to IAEA "Advisory Material for the IAEA Regulations for the Safe Transport of Radioactive Material", the retention of radioactive material transport package need to be paid attention. Finite Element (FE) method is an efficient way to verify the retention system. Two typical kinds of retention systems are simulated by FE. Two important aspects, mesh density and contact model are discussed for their influence of the calculation time and calculation accuracy. The method could be promoted to other aspects in radioactive material transport.
