Abstract: A simulating calculation method for collision accident of high temperature gas cooled reactor fuel transport package was introduced. The scene for severe collision accident from real package structure and transport condition was determined. With finite element method calculating, the results of different attitudes, different velocities of the colliding for the package were analyzed. The damage of different parts of the package and fuel assemblies were given. On this basis, the critical coefficient was calculated.

Key words: package, collision, simulating calculation, finite element, critical analysis, HTGR, fuel
