摘要

<jats:p>As the backup systems of RPS (reactor protection system), Diverse Actuation System and ATWS( Anticipated transients without scram) mitigation system are diversely designed from RPS system so as to offer protection for the normal operation of nuclear power plant. Both of the systems bear the function of mitigating the anticipated transients without scram events. Being isolated from RPS system, the design of DAS and ATWS system meeting the requirement of diversity and influences of CCFs (common cause failure) are effectively prevented. This article mainly analyzed the structure and function of the two systems and the similarities and differences between them.</jats:p>
