Abstract

This report establishes the basis and scope of work for the Three Mile Island Unit No. 2 (TMI-2) Accident Evaluation Program sponsored by the Department of Energy (DOE). The current understanding of the TMI-2 accident is reviewed, with emphasis on the end-state distribution of important radioisotopes and the progression of core damage leading to gross core failure and fuel migration into the lower plenum regions of the reactor vessel. Unresolved technical issues related to core damage progression and fission product behavior in hypothesized reactor accidents are identified. The role of TMI-2 accident research in addressing these unresolved issues is developed and discussed. Data needs from TMI-2 and supporting analysis requirements to interpret the data are identified that will improve our understanding of the important physical processes and parameters controlling core damage progression and the resulting fission product behavior. 48 refs.
TMI-2事故评估计划
本报告确定了由美国能源部(DOE)赞助的三里岛2号机组(TMI-2)事故评估计划的基础和工作范围。回顾了目前对TMI-2事故的理解,重点是重要放射性同位素的最终状态分布和堆芯损伤的进展,导致堆芯总体失效和燃料迁移到反应堆容器的下部全会区。在假设的反应堆事故中,确定了与堆芯损伤进展和裂变产物行为有关的未解决的技术问题。TMI-2事故研究在解决这些未解决问题中的作用得到了发展和讨论。确定了TMI-2的数据需求和解释数据的支持分析需求,这将提高我们对控制堆芯损伤进展和产生的裂变产物行为的重要物理过程和参数的理解。参48。
