Criterion 2: Quantification (for both composition and mass) of recycle, waste, and product streams that demonstrate projected material balance with no significant deviations.

Specific goals to meet criterion 2:

  1. Develop uranium product specifications with range of acceptable impurities: plutonium, neptunium, technetium-99 and ruthenium-106. Specify process-operating parameters for uranium ingots that meet uranium specifications.

  2. Develop metal waste specifications that are based on performance characterization results of small samples with variations in the principal constituents: zirconium, uranium, technetium, plutonium, neptunium, and noble metals. Determine performance characterization with electrochemical techniques, corrosion tests, vapor hydration tests, and attribute tests.

  3. Develop metal waste process specifications for major process variables: operating temperatures, hold time, and cooling rate.

  4. Develop ceramic waste specifications that are based on performance characterization results of samples with principal constituent variations: glass, fission products, uranium, and plutonium. Determine performance characteristics with attribute, characterization, accelerated, and service condition tests.

  5. Develop ceramic waste process specifications for major process variables: free chloride, zeolite moisture content, and chloride per unit cell.

  6. Quantify volume of low-level and transuranic waste generation under standard operating conditions.

  7. Return the cathode processor condensate to the individual ERs (electrorefiners) during the 16-kg driver per month for 3 months and 150 kg blanket per month operations.

  8. Specify unit process operations for metal spent fuel treatment, uranium ingot production, and waste form production.

  9. Estimate mass balances for uranium, transuranics, sodium, and key fission products for overall process.

  10. Prepare the flowsheet and develop process specifications for the subsequent inventory operation.

Criterion 3: Demonstration of an overall dependable and predictable process, considering uptime, repair and maintenance, and operability of linked process steps.

Specific goals to meet criterion 3:

  1. Record facility and equipment availability for process operations during the 3-month 16 kg per month driver demonstration.

  2. Record process interruption for chemistry results during the 3-month operation at 16 kg per month.

  3. Develop quantitative process models for each key step in the treatment process.

  4. Develop a process model that estimates throughputs as a function of equipment availability, maintenance requirements, and individual process times.
