Development of ITER tritium transport package

► A new tritium transport package has been developed for tritium supply to ITER. ► Functional, interfacial, regulatory requirements of the package are described. ► Design concepts and important features of the package are described. ► Structural and thermal safety of the package is demonstrated using analyses. For tritium supply to the fusion reactor of ITER (International Thermonuclear Experimental Reactor; the way to new energy) [1], tritium needs to be transported from tritium production sites, mainly the CANDU type reactor sites to the Tritium Plant building of ITER. Korea Atomic Energy Research Institute (KAERI) was commissioned the work of developing the transport package for tritium by ITER organization and the first stage of the development has been finished. The developed package was designed to carry 70g of tritium and classified as a type B(U) package, which should comply with the requirements stipulated in IAEA regulations for the transportation of radioactive materials [2]. The package is composed of a storage vessel, a containment vessel, an overpack and an aluminum liner, which is a unique feature of the package. The aluminum liner between the storage vessel and the containment vessel is for containment control under the repetitive use of the package. The package has enough pressure resistance for 5 years in-site storage and the structural and thermal integrity under the hypothetical accident conditions has been demonstrated through a series of analyses.
