Modelling of sloshing flow inside a Lead-cooled Fast Nuclear Reactor during an earthquake is conducted, focusing on the evaluation of the loads caused by the fluid on the structure. AQUAgpusph, a free software OpenCL accelerated SPH code has been used. This tool is analysed, including the performance comparison with some available GPU accelerated SPH codes, and its validation against SPHERIC test case number 10 about severe sloshing phenomena. SPH fits particularly well to this application due to the complex nuclear reactor geometry. Simulations have been conducted with ELSY lead-cooled fast reactor geometry.
