Design Analysis of A SCWR Fuel Assembly Using a Coupled Method
Due to its high thermal efficiency and economical competitiveness, SCWR has achieved significant interests of nuclear industries and research institutions. R&D programs have been launched worldwide to study the phenomena involved in SCWR. Design of fuel assemblies of thermal SCWR is one of the main challenging tasks due to: complicated fuel assembly configurations and strong coupling effect of thermal-hydraulics with neutron-kinetics. In the present paper, new design concepts of SCWR fuel assembly were proposed. The thermal-hydraulic performance and neutron-physical behavior of the new fuel assemblies were investigated using the newly developed coupled code. The results achieved so far indicate that the new fuel assembly design has a more uniform distribution of the power density and the coolant enthalpy rise compared to the previous ones.
