摘要提出了一个计算有针孔破裂的旧核燃料干式储存容器的降压时间和颗粒释放的模型。对破口路径内的颗粒沉积和传输给予了特别关注。该模型本质上是模块化的，其开发方式允许对内部温度、内部组件几何形状或气溶胶流动进行更先进的处理。该模型可作为解决与长期干桶储存期间的监测和核查工作有关的关切的基础。
Abstract A model is presented for calculating depressurization time for and particulate release from used nuclear fuel dry storage containers that have developed a pinhole breach. Particular attention is given to particulate deposition and transmission within the breach pathway. The model is modular in nature and is developed in a way that allows for more advanced treatments of internal temperature, internal component geometry, or aerosol flow to be readily incorporated. The model can be treated as a basis for addressing concerns associated with monitoring and verification efforts during long-term dry cask storage.
