Expert Group on Multi-physics Experimental Data, Benchmarks and Validation (EGMPEBV)


    Under the guidance of the OECD-NEA Nuclear Science Committee, the Expert Group will deal with the activities associated with the certification of experimental data and benchmark models along with establishing the processes and procedures for using the data and benchmark models for validation of modelling and simulation tools and data.


    • to provide member countries with the guidance and processes for certifying experimental data for its use as a benchmark or for its use in general testing of modelling and simulation tools;
    • to provide member countries with access to certified experimental data from the contributions of individual member countries;
    • to provide member countries with guidance and recommendations for developing benchmark models from certified experimental datasets;
    • to provide member countries with access to standardized benchmark models with detailed uncertainty evaluations and uncertainty methodology guidelines;
    • to provide member countries with recommendations and guidelines for the range of applicability of the certified experimental datasets;
    • to provide member countries with guidelines and consensus recommendations for validating multi-physics simulations;
    • to provide member countries with a limited number of demonstrations of the validation recommendations.

    The expert group will liaise closely with other relevant NEA working parties and expert groups, including those operating under the guidance of the Nuclear Development Committee (NDC) and the Committee on the Safety of Nuclear Installations (CSNI), to ensure that the respective programs are complementary and to provide advice and support where required and undertake common work where appropriate.
