Abstract
An electromagnetic pump of the helical annular linear induction type has pumped flow along paths which lie both inside and outside pipes (21) passing through the pump annulus (14). The pipes may be sampling pipes of failed fuel element detection apparatus. A number of pumps according to the invention may be arranged in cascade with selected pipes passing in series through selected combinations of pumps in the cascade so that, with an appropriate energization of selected pumps, flow along one pipe can be created while flow along other pipes is prevented.
