Conference paper: THE ROLE OF CFD SIMULATIONS IN CRS4 SUPPORT TO LIQUID METAL FAST REACTORS DESIGN

Thanks to the opportunity of being partner in several EURATOM projects, CRS4 developed many complex CFD applications in the innovative nuclear systems field. We illustrate the CFD model of the primary coolant loop of MYRRHA, built in the SEARCH and MYRTE projects. Well aware that the modelling needs to be validated, we compared the numerical results with relevant data, obtained with experimental dedicated campaigns: the Control Rod insertion in the MAXSIMA project and the simulations in the SESAME-Stand experimental facility, investigating the lead solidification. In both cases, the confront has brought decisive modelling improvement and better understanding of the experimental results. The last application regards the CFD modelling of the ALFRED primary coolant loop, strongly parameterized so as to investigate several possible design variants. The control demonstrated on the CFD modelling thanks to the EURATOM projects is allowing CRS4 to propose itself as a complementary partner in the network of specialists supporting the design of innovative GEN-IV nuclear systems.
