I have always wondered about that commercial. Notice they only say fuel. Maybe it's uranium or plutonium.
They probably design them the way they do because it is cheaper and easier. It is always easier to build a box out of steel than any curved shape. And probably for industry standardization as well. Just like tractor trailers.
