The production of suitable waste forms has not been demonstrated and poses a noteworthy challenge. Within the context of the problem of managing DOE SNF, a development program should be directed toward, and limited to, demonstration of those components of the technology that could be used to satisfy Me reasonably foreseeable needs and schedules of the DOE.

The two major milestones scheduled through the spring of 1996 are treatment of the first four River assemblies (June 1995) and start of the production of a sample metal waste form (March 1996~.

processing plan. The specific elements Tom ANE's proposed activities through the spring of 1996 that are necessary for the treatment of EBR-~l fuel and blanket assemblies are the following: Conclude tests of anode screen basket for fission product recovery; Demonstrate high-~roughput electrorefiner design concept; · Demonstrate the filll-scale cathode processor; Demonstrate electrolyte filtration for particulate removal; Demonstrate eng~neering-scale zeolite column, dehydrating, and hot blending preparation equipment; 35

Because there are no current plans to apply the electrometallurgical process to Hanford's K-basin sludges, oxide filets other than oxidized N-reactor assemblies, or waste forms, the committee believes Hat the portions of the ALL proposal relating to these important problems are premature. Underlying all these processing activities is the clear but infrequently articulated need to provide absolute assurance that a critical mass cannot be accumulated during any process step.

The electrometallurgical process will not readily handle all types of DOE SNF; head-end processes need to be developed. Waste forms are not yet developed, qualified, certified, or accepted.
