Abstract
The Transport Container Standardisation Committee (TCSC) is a UK nuclear industry group whose main function is to examine the requirements for the safe transport of radioactive material with a view to standardisation and, as appropriate, produce and maintain guidance documentation. The Code of Practice \"Guide to the Securing/Retention of Radioactive Material Payloads and Packages During Transport\", TCSC 1006 was published in December 2012 following an extensive review lead by Onet Technologies, Peer Review and approval by TCSC committees. The code considers the requirements governing restraint, provides design criteria for various modes of transport and makes recommendations regarding operation and inspection for tie-down systems. This paper reviews the history of TCSC 1006 as it has developed since it was first published in 1971 and the changes that have occurred since it was last updated in 2003. It summarises the review process that has been undertaken which included a thorough review of the relevant sections of the IAEA regulations and outlines the main changes from the previous edition which are: Acceleration factors for all modes of transport which are used to determine the tie-down loadings have been updated Additional guidance is provided on the design of specific tie-down systems New sections added on payload restraint within a package and special considerations for transport frames An extensive review of acceleration factors for the various modes of transport was undertaken and recommended values are included in TCSC 1006 as an interpretation of the guidance provided in the IAEA Advisory Material for use in the UK. The paper highlights a number of inconsistencies in the IAEA Regulations and guidance regarding routine and normal conditions of transport when applied to package restraint, particularly the advice that a package is permitted to separate from a conveyance in normal conditions of transport.
