However, ever since the dismantling of several old sodium installations facilities, CEA has at its disposal an important stock of unused powder batches, some of which have not been kept in suitable conditions. The idea of reutilizing these powders initiates the question about their efficiency to extinguish a sodium fire after long term storage. The various physicochemical analyses that have been carried out to characterize these stocked powder batches highlight the presence of lithium sodium carbonate (LiNaCO3), which is not a product of aging, and trôna that, contrarily, formed because of aging during storage. This study presents the first experimental results of small sodium pool fire extinction using the powder samples previously characterized. The presence of trôna did not affect significantly the extinction. Moreover, it did not affect the fusion temper...
