核反应堆的运转,要求准确地测量和控制反应堆内的温度。然而,在核反应条件下,准确的温度测量是很难做到的。为在那样环境中使用而设计的热电偶,必须在较高的温度(例如从约1000℃到至少2000℃)下能良好地工作,且其热电势应不受高巾子辐照的影响。在核反应堆的运转或反应堆材料的堆内试验中,要准确地测量和控制温度,热电偶是唯一可采 The operation of a nuclear reactor requires the accurate measurement and control of the temperature inside the reactor. However, accurate temperature measurements are difficult to achieve under nuclear reaction conditions. Thermocouples designed for use in such environments must function well at higher temperatures (eg, from about 1000 ° C to at least 2000 ° C) and their thermoelectric potential should not be affected by the high irradiance of the towel. Thermocouples are the only recoverable to accurately measure and control temperature during operation of a nuclear reactor or in-reactor testing of reactor materials
