“…In support to this conclusion Park et al (2008), reported that the effective removal of the decay heat from the core can be achieved by steadily flowing single phase coolant in the primary loop. Mente et al (2014) demonstrated the heat removal by natural circulation and to understand the effect of heat removal by inter wrapper flow. Minocha et al (2015) also investigated three dimensional natural circulation phenomenons in passive safety systems for decay heat removal in large pools.…”
