Abstract

Abstract: China Institute for Radiation Protection (CIRP) was commissioned the work of developing FCTC10 container. FCTC10 container is designed to transport 60 Co special form radioactive sources used in irradiation industry. With a loading of 6.7×10 15 Bq, the package is a Type B(U). The dynamic finite element analyses were performed. The structural integrity of the transport package was evaluated considering the hypothetical accident condition conditions include 9 m free drop on rigid surface (drop I). we considered several candidate drop postures, including top over-the-corner drop, side drop and top drop, which are known to cause the most severe damages to the packages of cylindrical shape in most cases. It is shown that the posture of top over-the-corner for 9 m free drop is the most damaging posture, and the posture is chosen as the best experiment program in the following physical experiment of real package. And also the simulation results of deformation of a whole or a part of the package play a guiding role in the optimal design and experiment of container.
