核临界安全操作中临界事故报警系统的使用

[中文适用范围]： 本文件提供了有关在核设施运行中使用 CAAS 的要求和指导。IEC 60860 提供了有关 CAAS 设计的要求和指导。本文件适用于在核反应堆外但在核设施边界内的裂变材料操作。当确定需要 CAAS 时，本文件适用。有关 CAAS 需求的信息见附件 C。本文件不包括管理步骤的详细信息，这些步骤被视为强大管理系统的活动（ISO 14943 提供了管理步骤的详细信息）。核事故剂量测定和人员暴露评估的细节不在本文件的范围内。本文件涉及伽马和中子辐射率传感系统。集成系统也可以满足特定的检测标准；也可以使用检测中子或伽马辐射的系统。然后适用等效考虑。 [外文原描述]： This document provides requirements and guidance regarding the use of CAAS for operations of a nuclear facility. Requirements and guidance on CAAS design are provided in the IEC 60860 . This document is applicable to operations with fissile materials outside nuclear reactors but within the boundaries of nuclear establishments. This document applies when a need for CAAS has been established. Information about the need for CAAS is given in Annex C . This document does not include details of administrative steps, which are considered to be activities of a robust management system ( ISO 14943 provides details of administrative steps). Details of nuclear accident dosimetry and personnel exposure evaluations are not within the scope of this document. This document is concerned with gamma and neutron radiation rate-sensing systems. Specific detection criteria can also be met with integrating systems; systems detecting either neutron or gamma radiation can also be used. Equivalent considerations then apply.
