Nuclear reactor fuel element assemblies

摘要

A nuclear reactor fuel element assembly comprising a bundle of fuel elements in a tubular wrapper for conducting liquid metal coolant flow has a cavitation suppressing impedance. The impedance comprises a tubular member housing a series of flow defining plates the plates comprising two sets arranged so that plates of each set are positioned alternately along the tubular member, the plates of one set being of woven wire mesh and those of the other set being thick apertured plates.
