A type of SCWR core design with Double-row fuel rods assembly will be introduced in this paper. The Double-row fuel rods SCWR (DL-SCWR) core is designed for reaching a thermal power of 2280 MW with an equivalent diameter of 3.16 m and length of 4.20 m. There are 249 fuel assemblies in the core, and 180 fuel rods in each assembly. The inlet coolant temperature is 280 °C and the operation pressure is 25 MPa. There are 80 fresh assemblies in the equilibrium cycle. The numerical results show that the average discharged burnup of the equilibrium is 37 GWD/tU, and the average temperature of outlet coolant is 500°C. In the equilibrium cycle, the maximum cladding surface temperature is less than 650 °C.
