Fuel Rod (Depleted MOX)
Depleted MOX is MOX that has been used up by the nuclear reactor.
Having depleted MOX in one's inventory will give the "Radiation" effect unless wearing a full Hazmat Suit.
Place it in a Thermal Centrifuge and the Depleted MOX will yield the iron dust originally used to make the fuel rod as well as 3 pieces of Plutonium and 1 small pile of plutonium. Using MOX will not return any of the U-238 used in making the MOX.
