How big would an explosion have to be to measurably affect the Earth's orbit?

For instance, (ignoring environmental issues), if we took all the nukes and blew them all up in one location, would it affect the Earth's orbit?  Or if we somehow took all the world's radioactive material, put it in one place and managed to ignite fission, would that do it?

None of those would do anything (other than destroy all life on the planet).  Momentum is conserved, so assuming no debris from the explosion can escape Earth's gravitational pull entirely, the Earth must continue on its path.
