Abstract

Abstract: A one-dimensional transient code is developed for studying the flow transient in the supercritical CO2 natural circulation loop. The transient code is validated with the experimental result. Various flow transients such as flow initiation, power step up and power step back have been studied. The effect of operational parameters and geometrical parameters on flow initiation transient also has been studied. In all cases steady state has been reached and instability is not observed in vertical heater vertical cooler configuration of supercritical CO2 natural circulation loop.
