RECENT APPROVAL OF THE UX-30 AS A TYPE B PACKAGE - Presentation

The UX-30 packaging has recently been authorized by USNRC as a Type B(U)F package for transport of greater than Type A quantities of recycled UF6 in 30B or 30C cylinders. The contents are limited by: the quantity of uranium hexafluoride, the fission product gamma activity and the transuranic alpha activity, the hydrogen to uranium atomic ratio, and the total activity. The use of the packaging for transport of Type B quantities of uranium hexafluoride requires that the 30B or 30C cylinder containing the uranium hexafluoride meet the leak test criterion of “leak tight”. A maintenance requirement has been added to specify annual testing of 30B or 30C cylinders used for Type B quantities of reprocessed uranium hexafluoride. The USDOT has endorsed this approval and approvals have been requested in various other countries. The paper discusses the specific requirements of the newly authorized contents along with the additional leak test conditions that apply to this expanded content. The current status of endorsement by other countries is also presented.
