FPGA technology application in diversity actuation system of nuclear power plant

In AP1000 nuclear power plant (NPP), the diversity actuation system (DAS) provides a backup to the protection system. This paper focused on the function and structure of DAS, the filed programmable gate arrays (FPGA) technology and application of FPGA in DAS. The results show that the FPGA performs the characteristics of diversity, simple, high reliability, short response time and good security. And the FPGA can meet the requirement of diversity actuation function and relate rule. ©, 2014, Atomic Energy Press. All right reserved.
