Thermal Modelling of the SAFESHIELD 2999A Package

The SAFESHIELD 2999A is a general purpose container, designed by Croft Associates, for transporting small volumes of radioactive materials that require heavy shielding. It is intended for carrying materials as diverse as source capsules and accelerator targets. An experimental heating test to determine temperatures under normal conditions of transport (NCT) has previously been performed. A pool fire test has also been carried out in order to demonstrate the temperature of the package during hypothetical accident conditions (HAC). Finite Element modelling of the container has also been performed, however, in order to extend the test data to regulatory conditions by including, for example, the effect of solar insolation.
