For instance, China has designed the "passive residual heat removal system at the secondary side of vapor generator" based on problems reflected in Japan's Fukushima nuclear accident, which can remove the heat from reactor cores in time, avoiding the meltdown of reactor cores.
例如，针对日本福岛核事故所反映出的问题，中国设计了“蒸汽发生器二次侧非能动余热排出”系统，能够将堆芯热量及时排出，从而避免堆芯熔毁的发生。
