The aim of this paper is to correlate experimentally measured pressure drop data across grid spacers to the set of correlations proposed by Rehme, based on the experiments performed in a water loop at the Scalbatraio Laboratory of Pisa University (2003), as well as in a water loop of the KALLA test facility (2008). Based on the presented study one can state that using slightly modified Rehme/Dalle Donne pressure drop correlations for pressure drop prediction in a fuel bundle with grid spacers, it is possible to obtain very good agreement with the experimental measurements of the fuel assembly pressure drops in various segments of a fuel assembly, provided that the grid spacer blockage factor can be estimated to a reasonable degree of confidence.
