Impact Analyses of a New SAFKEG

A new Safkeg has been developed by Croft Associates Ltd for the shipment of materials between UK licensed sites. It has been designed to satisfy all the requirements of a B(M)F package as specified in the IAEA Transport Regulations.Impact performance of the package has been demonstrated by a combination of physical drop testing and finite element analyses. The finite element analyses have been used to demonstrate the performance of the package in normal and accident conditions of transport impacts, under temperature and pressure conditions which have not been addressed in the physical drop tests.Two series of drop tests were carried out. In each series of tests, a sequence of tests in the centre of gravity over lid edge orientation followed by a sequence of tests in the axis horizontal orientation were carried out.A state-of-the-art detailed finite element model was developed. It was validated against the drop tests and then used in the detailed analyses and evaluation of eight separate impact cases.This paper presents a summary of the finite element analysis - modelling, validation, analysis and evaluation.
