During 150 min of the experiment we were able to detect and monitor the evolution of a liquid sodium leakage on the surface of the pipe. %G English %2 https://cea.hal.science/cea-01828512/document %2 https://cea.hal.science/cea-01828512/file/article_EBoldyreva_OFS-23.pdf %L cea-01828512 %U https://cea.hal.science/cea-01828512 %~ CEA %~ DRT %~ DEN %~ LIST %~ DEN-CAD %~ CEA-CAD %~ DM2I %~ DIN
