钠冷快中子增殖堆(钠冷快堆)是一种最成熟、最具商业化前途的快堆堆型。但由于其材料、冷却剂安全性及经济竞争力等方面的原因,国内仍处于实验堆运行阶段。由于缺乏钠冷快堆安全监管方面的法规、标准、技术及经验,监管工作面临巨大挑战。本文将钠冷快堆与压水堆进行比较,并将钠冷快堆的特点与监管工作的特点相结合,从堆芯、系统及设备等方面提出15个监管重要关注点,并给出一系列相关建议。
The sodium-cooled fast neutron breeder reactor (sodium-cooled fast reactor) is one of the most mature and commercially viable fast reactor stacks. However, due to its material, coolant safety and economic competitiveness, China is still in the experimental reactor operation stage. Due to the lack of regulations, standards, technologies and experiences in the safety regulation of sodium-cooled fast reactors, the regulatory work faces enormous challenges. In this paper, the sodium-cooled fast reactor is compared with the pressurized water reactor, and the characteristics of the sodium-cooled fast reactor are combined with the characteristics of the supervision work. Fifteen important regulatory concerns are proposed from the core, system and equipment, Series of related suggestions.
