Most modern goods are valuable and hard to replace because of their mechanical or chemical properties, and so blowing them up destroys the value. My understanding is that U-235 is not like that, blowing it up accomplishes very little when recovery consists of what they'd already be doing to clear the debris, plus some mechanical and chemical separation.
