(307h) Thermal-Hydraulics, Transient Turbulence, and Two-Phase Flows in a Pressurized-Water Small Modular Nuclear Reactor
The reactor pressure vessel consists of primary and secondary coolant loops. The primary coolant extracts heat from enriched UO2 fuel rods, and transports this heat via turbulent flow past internal structures to the tube-side of the integral steam generator. The secondary coolant flows in on the shell-side of the integral steam generator and extracts sufficient heat to exit as a steam-water mixture with ~60% quality, providing secondary-side electricity generation equipment with a deliverable power of 225 MW. These phenomena were simulated and analyzed, and are presented herewith.
