Abstract

Abstract

The digital protection system of China Mianyang Research Reactor has been developed, which is based on the parallel processing of MCU and FPGA, three checking channels, the partial logical, double judge. The analysis of the system shows that it is reliable and safe, any single fault can not hinder the implementation of the system’s safety function, and the failure probability is less than 10^-5. It has been running for four years to prove that it meets the requirement of China Mianyang Research Reactor.
