摘　　要：文章对模块式小型堆(ACP100)在反应堆满功率运行时的落棒事故进行分析,研究模块式小型堆在落棒事故后堆芯的热工安全。落棒事故计算分析的结果表明,对于ACP100,即使发生了功率运行状态下落棒事故,最小DNBR仍高于限值,燃料棒发生DNB的份额为0,满足安全限值准则的要求。事故发生后,操纵员可以根据操作规程将反应堆带入安全状态。With the rapid development of industrial level,the demand for regional transfer,utilization and disposal of hazardous waste in China is on the rise.China has established a hazardous waste transfer management system,implemented the hazardous waste transfer joint list system,and carried out the whole process management of hazardous waste.This paper analyzes the problems existing in the cross regional transfer of hazardous waste,such as the mismatch between the regional utilization and disposal capacity and the demand,the weak sense of responsibility of the main body of waste production enterprises,and the complexity of the cross regional transfer process of hazardous waste,and puts forward suggestions.
