核设施.仪表和控制系统.正常运行和预期运行期间使用的已安装区域γ辐射剂量率监测设备的设计 位置和应用标准

[中文适用范围]： 本文档适用于核设施中用于监测正常运行和预期运行事件期间当地伽马射线剂量率的安装设备的设计、位置和应用。IEC 60951-1 和 IEC 60951-3 当前解决的事故条件的高量程区域伽马射线剂量率监测设备不在此文档范围内。本文档不适用于中子剂量率的测量。本文档提供了关于设计原理、位置、应用、校准、操作和测试的指导方针，用于在核设施中正常运行条件下和预期运行事件期间连续监测当地伽马射线剂量率的安装设备。这些仪器通常被称为区域辐射监测器。便携式仪器也用于此目的，但不在此文档范围内。用于区域辐射监测设备的辐射监测器在 IEC 60532 中讨论。如 IEC 60532 所讨论，伽马射线的测量可以根据国家法规用多种不同的量来表示。然而，对于此类仪器，最可能测量的量是空气比释动能 (Gy) 或环境剂量当量 H*(10)(Sv)。 [外文原描述]： IEC 61031:2020 applies to the design, location and application of installed equipment for monitoring local gamma radiation dose rates within nuclear facilities during normal operation and anticipated operational occurrences. High range area gamma radiation dose rate monitoring equipment for accident conditions currently addressed by IEC 60951-1 and IEC 60951-3 is not within the scope of this document. This document does not apply to the measurement of neutron dose rate. Additional equipment for neutron monitoring may be required, depending on the plant design, if the neutron dose rate makes a substantial contribution to the total dose equivalent to personnel. This document provides guidelines for the design principles, the location, the application, the calibration, the operation, and the testing of installed equipment for continuously monitoring local gamma radiation dose rates in nuclear facilities under normal operation conditions and anticipated operational occurrences. These instruments are normally referred to as area radiation monitors. Portable instruments are also used for this purpose but are not covered by this document.
