Sl-1
SL-1(英語:,中文翻译为固定低功率反应堆1号),是美军的实验性核动力反应堆,1961年1月3日经历了蒸汽爆炸和堆芯熔毀,造成3名操作人员死亡,反應堆容器插頭(reactor vessel plug)將其中一個釘在天花板上[1][2][3][4]。直接原因是负责吸收中子的控制棒在设计不佳的堆芯中不当撤出。它仍然是美国唯一一起造成立即死亡的反應爐事故[5]。
事故發生時,堆芯功率水平在短短4毫秒內達到近20 GW,引發爆炸[6][7][8]。这次事故释放了大约80居里的碘-131,大约1100居里的裂变产物被释放到了大气中。
该设施位于国家反应堆试验站靠近西爱达荷州40公里偏远沙漠地区,作为陆军核电计划的一部分,是已知的在设计和建设阶段的阿尔贡低功率反应堆(ALPR),旨在为远程军事设施提供小型电力和热能,如靠近北极圈的雷达站和远距离预警线。设计功率为3MW热能。操作功率为200KW电力和400KW热能的局部暖气。
