CEFR的冷却剂为化学性质非常活泼的金属钠,这使得快堆一回路涉钠设备和部件的装拆及物理启动需要系列大型成套装置,以防止污染冷却剂钠及避免可能引起的钠火和沾污。这一系列的成套装置,习惯上称为CEFR“专用工具”,具体包括: CEFR’s coolants are very chemically inert metallic sodium which makes the assembly and disassembly and physical activation of sodium-related equipment and components of the fast reactor a series of large complete sets of devices necessary to prevent contaminating the sodium of the coolant and to avoid possible sodium fire and Contamination. This series of devices, commonly known as CEFR “special tools”, including:
