Also there's no safe distance
The debris will just keep going til it hits something.

Apart from air resistance
Air would be required for a non-nuclear explosion (air for fuel). I don't think you'd want to be anywhere near the nuclear version of this :-) There would be a safe distance, but it would be vastly increased from the safe distance required on Earth. Whatever atmosphere the explosion took place in would slow debris through friction (though very slight). Sorry, physics pedant :-)

Explosives don't require air...
... they have their own oxygen bound up in compounds such as nitrates. That's what makes them so devastating. They "burn" on thier own without waiting for the air to get in.

In zero G the explosion would be spherical rather than mushroom-shaped (no convection).

Needs to be done.
