SESAME TO COLLABORATE WITH US PARTNERS ANL AND ORNL
SESAME TO COLLABORATE WITH US PARTNERS ANL AND ORNL

SESAME is proud to announce that the US/EURATOM I-NERI proposal to collaborate with the Argonne National Laboratory (ANL) and the Oak Ridge National Laboratory (ORNL) has been approved.

ANL and ORNL will participate in the project’s effort to improve the state-of-the-art in thermal-hydraulics simulation and validation experiments in support of the safety evaluation of liquid-metal cooled fast reactors (LMFRs). This cooperation will provide an opportunity to exchange measured data, code predictions, and modeling and simulation expertise.

US activities will focus on the validation of the thermal-hydraulics tools being used for LMFR design and safety performance and will be jointly supported by the Nuclear Energy Advanced Modeling & Simulation (NEAMS) and Advanced Reactor Technology (ART) programmes in the DOE Office of Nuclear Energy. The NEAMS programme is developing and deploying advanced modeling and simulation tools for nuclear reactor design and safety performance analysis, and ART is the DOE’s primary sponsor of LMFR technology development and safety & licensing efforts.

This collaboration concerns two specific SESAME work packages:

  • Analysis of Wire-Wrapped Fuel Assemblies
    • ANL will provide numerical high fidelity reference data for a wire wrapped rod bundle which is typically used in liquid metal fast reactors. These data will allow the EU partners to extend the validation base of their pragmatic simulation approaches.
    • ORNL will use the SESAME numerical and experimental reference data for wire wrapped rod bundles to determine the uncertainty quantification for pragmatic simulation approaches.
  • Analysis of the Phenix Dissymmetric Test
    • ANL will use experimental data from the SESAME project to develop and validate a full core simulation approach using their SHARP toolkit which is developed under the US NEAMS (Nuclear Energy Advanced Modelling and Simulation) programme.
    • ANL will participate with multi-scale analyses in the SESAME Phenix Dissymmetric test benchmark. This will allow the EU partners to compare their state-of-the-art results with the US state-of-the-art results allowing EU and US partners to mutually learn from each other and improve the modelling capabilities on both sides of the Atlantic.

SESAME partners NRG, SCK-CEN, ENEA and the University of Gent have already collaborated with ANL on a previous related I-NERI project titled “High-fidelity Thermal-hydraulic Fuel Assembly Simulations for Nuclear Reactors”.
