标准摘要
[中文适用范围]： 本国际标准提供了一种方法来估计假定临界事故的裂变次数的合理最大值。 裂变数估计与其假定的临界事故相关，影响事故应急计划和响应，因为它用于估计辐射剂量和放射性材料释放。 本国际标准不提供确定边界事故场景的方法和指南。 本国际标准不涵盖 ISO 7753 涉及的临界事故检测。 本国际标准适用于存在可信临界的核设施、工厂、实验室、裂变材料的储存和运输（但不适用于核动力反应堆堆芯）。 可能会发生事故。 [外文原描述]： ISO 16117:2013 provides a methodology to estimate a reasonably maximal value of the number of fissions of a postulated criticality accident. The fission number estimate, associated with its postulated criticality accident, impacts the accident emergency planning and response because it is used for the estimation of radiation doses and of radioactive materials release. ISO 16117:2013 does apply to nuclear facilities, plants, laboratories, storage, and transportation of fissile material (but not to nuclear power reactor cores) where a credible criticality accident may occur.
