An investigation on the pressure losses of two different candidate rod bundles, respectively for the projects EFIT (European Facility for Industrial Transmutation) and ELSY (European Lead-cooled SYstem), has been carried out and is presented in this report. For the EFIT design a hexagonal arrangement and far the ELSY design a square arrangement of the bundle have been retained, respectively. In both cases, the bundle is cooled by lead, or lead-bismuth alloy. Four correlations available in the literature have been taken into consideration. In addition, as the rods are not wire-wrapped and the channels they delimit might be assimilated to a straight fluid passage, all results of the previous correlations have been compared with those of the Blasius model far smooth circular tubes.

EFIT/ELSY - Pressure Drop Performance of the Rod Bundle

2007

Abstract

An investigation on the pressure losses of two different candidate rod bundles, respectively for the projects EFIT (European Facility for Industrial Transmutation) and ELSY (European Lead-cooled SYstem), has been carried out and is presented in this report. For the EFIT design a hexagonal arrangement and far the ELSY design a square arrangement of the bundle have been retained, respectively. In both cases, the bundle is cooled by lead, or lead-bismuth alloy. Four correlations available in the literature have been taken into consideration. In addition, as the rods are not wire-wrapped and the channels they delimit might be assimilated to a straight fluid passage, all results of the previous correlations have been compared with those of the Blasius model far smooth circular tubes. Results of all attempts are very similar.
