Accidents have also occurred when nuclear reactors are shut down for refueling or to move spent nuclear fuel into storage. In 1999, operators loading spent fuel into dry-storage at the Trojan Reactor in Oregon found that the protective zinc-carbon coating had started to produce hydrogen, which caused a small explosion.
在核反应堆停机补充核燃料或者移除核废料进行储藏的过程中也不乏事故。在1999年的美国俄勒冈州特洛伊反应堆，正在将核废料进行干储藏的操作人员发现由锌碳材料制成的保护罩开始产生氢气，并随后引发了一场小型爆炸。
