Abstract

Through the postulated loss of coolant accident (LOCA) in pressure water reactors (PWRs), the cooling water from the emergency core cooling system (ECCS) start and then inject into the cold leg. The scaling-down experiment aims to study the characteristics of thermal mixing in T-junction, including two subprojects: single phase thermal mixing test and two phase flow direct contact condensation test. The conclusion indicated that: The temperature field in the cross-section of pipes was affected by the jet flow on single phase thermal mixing test; In two phase flow direct contact condensation test, the mass of condensation after cooling goes to linear distribution with the jet flux.
