Cermet fuel assemblies of the APPR type were successfully dissolved in the semiworks electrolytic dissolver; a nonconducting basket of NEMA Grade G-7 plastic held the fuel during dissolution. Stray-current corrosion of the stainless steel dissolver vessel was eliminated by shielding the anode from the vessel. Recent semiworks tests suggest that some sodium-bonded power fuels might be dissolved safely in nitric acid in an electrolytic dissolver; the sodium was gradually exposed to the acid when a fuel rod was slowly lowered into an electrolytically active region at a temperature low enough (40 to 45 deg C) to prevent the sodium from flowing from the rod.
