Test of Critical Heat Flux on Outer Surface of CAP1400 Pressurized Reactor Vessel

Abstract

A full height sliced test facility is established based on the modeling process. The heating test section is manufactured by adopting the explosive welding technology, and the surface of carbon steel can simulate the actual surface characteristic of a pressurized reactor. Critical heat flux tests on flow, pressure, subcooling degree, chemical material in water, and surface characteristics are performed on the outer surface of the pressurized reactor vessel. Therefore, the law of heat transfer limit on the outer surface of the CAP1400 pressurized reactor vessel is obtained, and the process of flow and heat transfer for in-vessel retention is validated.
