Interactions with the SESAME Senior Advisory Committee

The SESAME project set up a Senior Advisory Committee, which is a consultative body that provides guidance and advice to the project on nuclear design- and safety-related issues according to the project scope. The members of this committee are composed of representatives of the European design teams for liquid metal cooled reactors completed by a representative from the US NEAMS programme, which is the US programme on Advanced Modelling and Simulation for Nuclear Energy.

As such, interactions with the committee members both ways are important for the project. During the first two years, several important interactions took place. First, lectures were provided by the ASTRID and MYRRHA representatives not only explaining the design of these reactors, but more importantly summarising the thermal-hydraulics related challenges and ongoing activities to the SESAME experts . These lectures confirmed the validity of the topics selected for the SESAME project, which connect generally very well to the challenges that the designers are facing. However, these lectures also revealed challenges that will not be solved by the project.

In particular, interactions with the MYRRHA representative have led to an improved focus with respect to the scope of the task on the inter-wrapper flow experiments and modelling efforts and the task on solidification. For the latter, interactions and useful discussions allowed to define in more detail the experiments to be performed by CV Rez in their Meliloo facility and by KTH in their TALL loop. With this more detailed definition, the complementarity and value of both experiments for the designers is increased.

Finally, the committee member acting on behalf of the US NEAMS programme attended one of the technical progress meetings, actively participating in the technical discussions. In addition, he contributed to the workshops on verification, validation, uncertainty quantification and best practice guidelines, again actively participating in the discussions and enriching the European views and experiences with the US perspective.
