Actinide and Fission Product Partitioning and Transmutation

    14th Information Exchange Meeting

    Hilton San Diego Mission Valley, San Diego, CA, United States
    17-20 October 2016


    The OECD Nuclear Energy Agency (NEA) organised the fourteenth information exchange meeting on actinide and fission product partitioning and transmutation (P&T). The meeting was held in San Diego, United States from 17-20 October 2016, hosted by the Idaho National Laboratory in co-operation with the International Atomic Energy Agency (IAEA).


    Partitioning and transmutation (P&T) are some of the key technologies for reducing the heat, radiotoxicity and volume of radioactive waste produced. Recent developments indicate the need for embedding P&T strategies into advanced fuel cycles considering both waste management and economic issues.

    In order to give experts a forum to present and discuss state-of-the-art developments in the field of P&T, the NEA has been organising biennial information exchange meetings on actinide and fission product partitioning and transmutation since 1990.


    The meeting covered scientific, as well as strategic/policy developments in the field of P&T, such as:  

    • fuel cycle strategies and transition scenarios;
    • role of P&T in potential evolutions of role of nuclear energy in future energy mix;
    • impact of P&T on waste: improved radioactive waste forms to enable P&T; radioactive waste management strategies (including secondary wastes);
    • impact of P&T on geological disposal: criteria and results;
    • impact of P&T scenarios on fuel and target designs, fabrication and behaviour, including material data and modelling;
    • advances in pyro and aqueous separation processes;
    • P&T specific technology requirements: materials, spallation targets, coolants, etc.;
    • transmutation physics, experiments and nuclear data requirements and validation;
    • transmutation systems: core design, performance and safety;
    • impact of P&T on the fuel cycle, in particular handling, storage and transportation of transmutation fuels;
    • economics of P&T.

    These topics included multi-scale modelling, experiments and instrumentation, novel theories and benchmarks.


    The meeting consisted of a plenary session, followed by technical sessions and a poster session that covered the technical subjects in the scope. Poster presenters were given the opportunity to present their work over a short presentation.

    At the summary session, reviews and findings of each technical session were presented by the session chairs.
