标准摘要
[中文适用范围]: 本国际标准适用于堆芯内使用的温度传感器和核动力反应堆主冷却剂回路的系统和部件设计、制造和测试方法的一般方面。这些传感器包括热电偶和 RTD(电阻温度检测器 – RTD)。重点放在核应用的特定特征上,并且仅当与反应堆主外壳内和/或高辐射场中的此类部件的容纳有关时才提出有关部件和传感器的建议。反应堆使用所施加的条件通常与非核应用中发生的条件不同。核心系统的某些部分可能位于非常恶劣的环境中。暴露在高中子和伽马辐射下很容易因核转变、加热和结构变化而产生误差,并影响设备的机械和电气性能,因此在安装和使用标准时必须格外小心材料的选择。此外,设计还需要考虑高环境压力、高温、温度梯度和温度循环的影响,以及温度测量系统影响反应堆安全或经济性能的方式。核条件对温度传感器的影响导致了严格的资格要求。该标准涉及核应用温度传感器的具体要求。它有两个目的: a) 提供指南,有助于确保反应堆条件不会损坏温度传感器; b) 确保堆内温度测量系统和传感器安装不影响反应堆的安全运行和可用性。做出了一般适用性的陈述,但详细考虑仅限于热电偶和 RTD。 [外文原描述]: IEC 60737:2010 deals with specific requirements for nuclear applications of temperature sensors. It provides guidance which will help to ensure that the reactor conditions do not damage the temperature sensors; it ensures that the in-core temperature measuring system and the sensor installation do not prejudice the safe operation and the availability of the reactor. Is applicable to general aspects of system and component design, manufacturing and test methods for temperature sensors used in-core and for the primary coolant circuit in nuclear power reactors. The main changes with respect to the previous edition are the following additions: - descriptions of the comparative performance of thermocouples and resistance temperature detectors; - discussion of the temperature measuring system requirements for reactors.
