Abstract: Compared with CPR1000, the third generation CEPR nuclear power plant uses the third generation of control, protection and supervise system of turbine for the first time. Equipment redundancy, performance and logic design have been optimized, therefore the reliability of control and protection have been improved. This paper compares the two techniques, introduces and analyzes the new features of this third generation technique, for the purpose of supplying information for the operation and maintenance. Since the new system will be used by the following nuclear power stations, this paper will share the information of the new features with the same trade.
