2MWt液态燃料钍基熔盐实验堆仪控系统纵深防御设计与分析

Defense-in-Depth Design of I&C in TMSR-LF1

研究堆的安全设计要求仪控系统具有纵深防御的特点,其设计需满足研究堆的总纵深防御目标,保证在堆的各种运行工况条件下,能可靠执行监测、控制、保护、报警等功能。为了保证实验堆仪控系统的设计满足我国及国际法规的要求,本文详细论述了研究堆仪控系统的纵深防御设计并对其与标准的符合性进行了分析。通过分析,得出了实验堆仪控系统纵深防御设计方案满足现有标准的要求和研究堆总的安全要求的结论,为实验堆仪控系统的设计提供参考。

The design philosophy of defense-in depth(D3)for research reactor is developed significantly.I&C design for research reactor,it shall meets the overall target of defense-in-depth,and performs reliably the required monitoring,control,protection,and alarm function in different conditions.In order to ensure that the I&C design meet the requirements of our country and international laws and regulations.The I&C design is discussed in detail and its compliance with the standard is analyzed.It is concluded that the design of the I&C can meet the total safety requirements of the research reactor.The study of this paper provides valuable reference for continuous improvement of the research reactor.
