DESIGN AND APPROVAL TESTING OF MODERN TYPE-B PACKAGINGS FOR THE TRANSPORT OF RADIOACTIVE-WASTE AND OTHER MATERIALS

This paper summarizes the design and approval testing of thr ee new de signs of type-B packaging which facilitate the transport of intermedia te-level radioactive materials within the United Kingdom and abroad. T he packagings are (a) the Nupak-200 type-B(U)F (b) the Transhield-20 t ype B(U)F (c) the DN3705/DN3726 type-B and type-A packaging family. Al though approval testing to IAEA regulatory standards applies equally t o packagings of any one type, the paper emphasizes different aspects o f this process for each of these designs. To date, three Nupak-200 pac kagings and two sets of DN3726 types (comprising three containers per set) have been manufactured for operational service. The DN3705 design s are currently in the final stages of certification and manufacture, and certification of the Transhield-20 design is also expected shortly .
