Scope

The Chemical Partitioning Subgroup (CPS) of the NEA Working Party on Partitioning and Transmutation (WPPT) is one of four Subgroups tasked with supporting the WPPT study to determine the potential viability of nuclear waste partitioning and transmutation as part of a waste management strategy.  The other subgroups are focused on accelerator utilisation and reliability, fuels and materials, and physics and safety. In support of the full NEA WPPT, the Chemical Partitioning Subgroup will:

  • Incorporate members of the NSC Expert Group on Pyrochemical Separations, together with a set of world experts in aqueous separations processes
  • Function as a separate group with a separate chater and schedule
  • Be focused on separations processes relevant to different partitioning and transmutation systems, covering a wide range of fuel types
The scope of the work includes the chemical separations processes that may be applied to a number of different fuel types:
  • Oxide
    • UOX
    • MOX
    • Non-fertile (inert matrix)
  • Nitride (fertile and non-fertile)
  • Composite (cermet, cercer)
  • Metal alloy (fertiel and non-fertile)
  • Graphite particulate (TRISO-coated)
  • Molten salt
    • U-TRU
    • U-TRU-Th

Objectives

Under the guidance of the WPPT, the CPS will  Perform a thorough technical assessment of separations processes in application to a broad set of P&T operating scenarios

    1. Technical feasibility assessments
    2. Mass balance flow sheet development
    3. Technological maturity assessment
    4. Decision analyses on technical issues
Identify important research, development and demonstration necessary to bring preferred technologies to a deployable stage Recommend collaborative international efforts to further technology development

Method of Work

Meetings will be held in conjunction with major international meetings, and/or meetings of the full WPPT.  The CPS will organise an International Information Exchange Meeting in 2002 - 2003. The principal product of the CPS will be a final report to the full WPPT due during 2004.  It will include an evaluation by the full CPS of the findings of the Information Exchange Meeting and include a technical summary of that meeting and all follow-on meetings. 
 

Meetings

  • 3rd meeting of the Working Group on Pyrochemistry and 1st meeting of the WPPT chemical partitioning subgroup were held in Issy-les-Moulineaux, France, 14-15 September 2001. 
  • 2nd meeting of the Working Group on Pyrochemistry was held in Issy-les-Moulineaux, France, 16-17 May 2001. 
  • 1st meeting of the Working Group on Pyrochemistry was held at the NEA Headquarters, 30-31 October 2000. 
  • Workshop on Pyrochemical Separations in Villeneuve-les-Avignon, France, 14-15 March 2000.
