ABSTRACT:
Failed fuel detection apparatus for nuclear reactors cooled by liquid metal has a pump (11) for impelling coolant metal along sampling pipes (10) to outlet points (10a) in the pipes. A rotary collector (15) is provided to scan the outlet points with a gap between the outlet points and the collector across which coolant in the sampling pipes can be impelled. The pump (11) is preferably of the helical annular linear induction type with the pipes passing through the annulus of the pump while being wetted internally and externally by liquid metal.
