MURR on the side of caution

The University of Missouri Research Reactor has awarded Abingdon-based Croft Associates a contract to supply a fleet of radioactive material shipping containers


The University of Missouri Research Reactor (MURR) has awarded Abingdon-based Croft Associates a contract to provide a fleet of radioactive material (RAM) shipping containers.



Croft will design and manufacture replacements to the DOT Spec 6M and Spec 20WC portion of the MURR RAM shipping container fleet. From 1 October 2008, many existing DOT Spec packaging types will no longer be authorised, meaning that replacement packaging must be NRC-certified Type B packaging as a condition of transport.



These replacement packages will consist of two basic designs to transport a wide variety of research, medical and industrial isotopes: the 6M replacement package Safkeg-LS and the 20WC replacement package Safkeg-HS.



The joint effort will use Croft’s packaging design, testing and Type B certification experience and MURR’s expertise in the handling and transport of RAM. The designs of these systems will be based on existing Croft Type B packages already certified to meet the International Atomic Energy Agency’s TS-R-1 standards in international RAM transport.



The Safkeg-LS and Safkeg-HS packaging will offer a variety of cavity sizes, shielding thickness and will be authorised for a wide spectrum of radioisotopes in both liquid and solid form.



Along with meeting the immediate needs of MURR, these two packaging types could also meet the requirements of other USA RAM shippers currently using a similar size 6M or 20WC DOT Spec packaging.
