Abstract

Within the framework of the ERCOSAM-SAMARA project, co-funded*by the European Union and the Russian State Atomic Energy Corporation, planning and pre-test calculations are performed to examine sensitivity parameters that can affect the break-up (erosion) of a  helium (substitute for hydrogen)  layer by mitigation devices (i.e., cooler, spray, or  Passive Autocatalytic Recombiner -PAR).  This paper reports the GOTHIC analysis results for the spray tests to be performed in the PANDA facility.  The  effects of spray flow rate, temperature and injection height  on depressurization, erosion of helium cloud and gas transport behavior are studied.  This analysis is valuable because only a limited number of conditions will be examined in the planned experiments.  The study provides a useful understanding of the interaction of spray with a stratified atmosphere.
