Abstract: CPR1000 nuclear power plants have the risk of reactor trip during the house load and turbine trip transients. Rapid power reduction system of AP1000 nuclear power plants and fast power setback system for VVER nuclear power plants are designed respectively, which can avoid this problem and thus provide more availability of units. It is necessary to introduce the Fast Power Reduction system to CPR1000 units to get more economy and flexibility. Based on the core control mode of CPR1000 units, the rod control assembly banks are regrouped to realize the fast power reduction function. Besides, the impact of fast power reduction system on the normal transients are evaluated. The results show that more operational margin can be released, and also the capacity of turbine bypass system can be reduced. Finally, more availability and economy can be obtained for CPR1000 units.
