The United States does not permit the reprocessing (i.e., recycling) of spent nuclear fuel into new fuel rods for which of the following reasons?

All of these

Security: there is some concern that plutonium separated from spent fuel could be used to make nuclear weapons if it fell into the wrong hands.

Fuel cost: Nuclear fuel is cheap to fabricate, so reprocessing spent fuel would not lower overall fuel costs for nuclear power plants.

Reprocessing costs: The recycling of nuclear fuel is too expensive to make it worthwhile.

None of these
