DESIGN & APPROVAL TESTING OF THE TRANSHIELD-20 TYPE-D ISO CONTAINER FOR DRUMMED PCM & OTHER WASTE

This paper summarises the design and approval resting ofthe Transhield-20 Type-B container in a programme that began in 1991 when the UKAEA anticipated a long-term requirement to transport 200-1 drums ofPC'M waste between its sites. This resulted in the design of two packagings : the Nupak-200 [Gaffka & Lawrence, Patram '95]. and the Transhield-20. a full-height 20' Type -B ISO container which has recently been adapted to carry heavy 500-1 drums The Transhield-20's construction is based upon the steel space-frame and resin- bonded cork construction proven on the earlier Nupak design The container was subjected to extensive drop-testing at AEA Technology's site at Winfrith. Dorset to qualify it to carry up to 3kg offissile material.
