Abstract

Abstract

According to the characteristics of small modular reactor, the key technologies of diversity protection system (RDA) are studied and analyzed. The design method of diversity protection signal based on the combination of probability theory and certainty theory is adopted for the first time, and the determination of protection signal setting value and delay time is deeply studied, which realizes the minimization of protection signal setting and the maximization of protection function; At the same time, with the comprehensive application of diversity and independent design technology in RDA design, a system architecture with high reliability and low misoperation rate is constructed, which significantly improves the safety and economy of small modular reactor, meets the requirements of defense in depth and diversity of nuclear power plant, and the relevant technical indicators have reached the international advanced level.
