AN EVALUATION OF THE ELECTROMETALLURGICAL APPROACH FOR TREATMENT OF EXCESS WEAPONS PLUTONIUM
In addition to the efforts noted above, the FMDP is preparing its Programmatic Environmental Impact Statement (PEIS) for Fissile Materials Disposition. The PEIS is the primary document that describes in detail the potential environmental impacts of technologies being considered for achieving the objectives of the FMDP. The PEIS is also one of the required steps in the process of arriving at a Record of Decision for the FMDP. Regarding the electrometallurgical technique, ANL has submitted a PEIS data call input draft report20 to the FMDP describing the immobilization of surplus fissile materials as part of the effort to evaluate the electrometallurgical technique for the treatment of spent fuels. In preparing the document, ANL assumed that the WPu disposition operations would be integrated with the treatment of spent fuels and that the same “hot” cells and some of the same equipment would be used. ANL indicates in the PEIS data call input draft report that the primary purpose of its treatment process is to convert spent fuel (primarily metallic or oxide fuel with stainless steel or zirconium cladding) into disposable waste forms.
