Description
Reactor core nuclear design of Qinshan-II NPP adopts the advanced PWR design ideas that appeared recently. The low linear power density is used in the core design to increase the core safety margin; it gives the reasonable arrangement of different enriched fuel assemblies and burnable poison rods to improve the core physical characteristics; and the core also uses one fourth OUT-IN reload manner to make full use of the fuel. The discharged burnup will reach 35 GW·d/t(U) and satisfy the requirement of annual reload mode. The calculating method and the design codes are advanced and were verified by many strict calculations. From the results of Daya-Bay NPP and Qinshan-II NPP calculated by use of these codes, one can believe that the codes are reliable in Qinshan-II design. The design shows that the core is advanced, safe and economical
