Abstract
The Hydride Transport Vessel (HTV) design was developed at Savannah River Site (SRS) as a means to transport tritium. When exposed to tritium gas, the depleted uranium in the HTV releases heat as the tritium is absorbed and forms a solid uranium tritide. Storing tritium as a solid provides advantages over a gaseous storage in both handling and transport safety. This paper discusses the ASME design requirements applicable to the HTV, the ASME Section III, Division 1, Subsection NB containment requirements associated with material transport and the ASME Section VIII, Division 1, Lethal Service facility process requirements associated with the hydride reaction. Design features and fabrication details unique to this vessel type are also discussed.
