Abstract

An equilibrium core of High Temperature Supercritical-Pressure Light Water Reactor is designed. Part of the feed water flows down the fuel assemblies loaded at the peripheries of the core, before flowing up the fuel channels in the inner region of the core. With this new flow scheme, the average coolant core outlet temperature is increased from 500C of the past design to 550C. The coolant flow rate for each fuel assembly is fixed by the inlet orifices to match the power generation. The maximum fuel rod cladding surface temperature is 650C.
