| Abstract: | Based on the COBRA-IV code,a new sub-channel code system developed for the supercritical water cooled reactor(SCWR) fuel assembly is analyzed.In order to optimize the SCWR fuel assembly design,a sub-channel analysis of two rows SCWR fuel assembly is performed,including steady-state and transient calculation.For the steady-state calculation,several channel’s parameters are selected to evaluate the thermal-hydraulic performance of the fuel assemblies.Based on the steady-state results,two transient calculations(change of fuel rod power and change of coolant flow) are carried out to estimate the dynamic behavior of the fuel assemblies.The results achieved so far indicate a good applicability of the sub-channel code for the SCWR fuel assembly analysis,which is good for the future optimization of SCWR fuel assembly design. |
