非能动停堆技术是提高大型钠冷快堆的安全性的重要技术,也是核能可持续发展研究的重要内容。课题在调研主要快堆国家的非能动停堆技术的基础上,完成了主要快堆国家(包括法国、俄罗斯、日本和德国等)非能动停堆系统综合报告,并给出了中国钠冷快堆非能动停堆技术选择。基于中国实验快堆大型数值计算的经验,建立了非能动停堆系统计算平台,提出了液体悬浮式非能动停堆系统钠和
Non-active shutdown technology is an important technology to improve the safety of large-scale sodium-cooled fast reactor and an important part of nuclear energy sustainable development research. Based on the investigation of the non-active shutdown technology of major fast reactor countries, the report completed the comprehensive report on the passive reactor shutdown system in major fast reactor countries (including France, Russia, Japan and Germany) Heap non-dynamic shutdown technology options. Based on the experience of large-scale numerical calculation of China Experimental Fast Reactor, a calculation platform of passive-stop system was established, and the liquid-suspended non-active shutdown system sodium and
