Abstract
For location of failed fuel cans in a sodium-cooled nuclear reactor, a gas flow under a pressure slightly higher than that of the sodium at the outlet of the fuel assemblies is supplied to the outlets of each of the assemblies in seriatim order. The resulting emulsion is raised by air-lift and collected in a tank located at a level higher than that of the outlet. The gas separates from the emulsion and a gas output from the tank is monitored to detect the presence of radioactive products therein.
