Some stuff about UF6:

UF6 is a stable compound when not exposed to air. At ambient temperatures it is a solid, and pinhole leaks in casks tend to seal themselves (not that you want a leaking cask...). Slight warming causes UF6 to sublime to a gas (that's why it's used in gaseous diffusion separations). The 48X and 48Y cylinders are usually shipped in overpacks that act as impact limiters if there is an accident. My guess about shipping by truck is that those were the most readily available cylinders and overpacks, but that's just a guess.
