PRISMA rig for the study of interactions between sodium and foreign components

During the life of a liquid sodium fast breeder reactor, some foreign components may accidentally fall into the circulating sodium of the primary loop. The products of sodium-components interaction would be transported to the fuel sub-assemblies (SA) and here they may originate some blockages, then the SA's refrigeration decrease. Therefore, to better understand the possible consequences (with risk assessment improvements) of these sub-assemblies accidents, it is much interesting to execute reaction tests among sodium and foreign components, into an adequate facility. In this report we will show the results of experimental tests which had been performed in the PRISMA rig in the period September 87 - April 88. The tests carried out regarded the sodium-oil interactions, with small amounts of reagents at various temperatures
