The Impact of Waste Gas Generation on the Design of a Sealed Packaging for Transuranic Waste Transport
Radioactive waste generates gas by several mechanisms, which can result in hydrogen and pressure build-up in a sealed packaging. The rectangular TRUPACT-II is used as a case study in the design and load management options for type B transport packagings for radioactive waste with significant gas generation potential. Data for existing transuranic waste at Department of Energy sites are reviewed, and recommendations are made for further research. Catalytic recombiners are recommended for prevention of flammable gas buildup due to hydrogen or methane generation. Waste containers that generate large quantities of gas may need to be mixed in with those that generate little gas in order to be shipped. A simple calculational method to aid this load management is described.
