A new concept of SCWR was studied ,including closed square fuel assembly with double-row rods ,low-leakage core of pressure vessel type reactor ,passive safety system , reactor control system , sliding-pressure start-up scheme , steam circulation system ,etc .The analyses of coupled neutronics and thermal-hydraulics ,sub-channel , typical accidents ,control system ,system stability and start-up process were carried out .The calculating results show that the major design of the core and system fulfils the design criteria ,and the SCWR design concept is balanced and feasible .
