FINLIB: a fin energy absorption data library for impact analysis of radioactive material transport cask with fins

摘要

In drop impact analyses for radioactive material transport cask with cooling fins, a relationship between fin plastic deformation and fin energy absorption is used. This relationship was obtained by ORNL and MONSERCO in Canada experiments. Based on ORNL experimental data, a data library computer program FINLIB for FINCRUSH program is developed to obtain the maximum impact acceleration and the maximum fin deformation. Main features of FINLIB are as follows: (1) not only making fin energy absorption data libraries from ORNL or MONSERCO experimental data but also comparative representations of ORNL and MONSERCO data are available, (2) it is capable of graphical representations for fin absorption energy data and (3) not only main frame computer but also work stations (OS UNIX) and personal computer (OS Windows) are available for use of FINLIB. In the paper, brief illustration of calculation method in fin impact analysis based on the ORNL research is presented. The second section presents descriptions of fin energy absorption data tested at ORNL and MONSERCO. The third section provides a user's guide for computer program and input data for FINLIB. (author)
