根据乏燃料池环境条件,乏燃料池液位、温度测量装置运行需求,针对丧失外电源情况下测量装置不能使用的安全风险,进行核电厂乏燃料池液位、温度一体化测量装置设计,并对工程样机进行功能、性能、环境试验验证。验证结果表明,装置测量精度高、实时,具备丧失外电源下的数据传输功能,满足乏燃料池的监测要求。
According to the environmental conditions of spent fuel pool, the level of spent fuel pool and the operation requirement of temperature measuring device, the integrated measuring device for level and temperature of spent fuel pool in nuclear power plant is designed according to the safety risk that can not be used by the measuring device in case of loss of external power source. The prototype of the project functions, performance, environmental test validation. The verification results show that the device has high measurement accuracy and real-time performance, and has the function of losing data transmission under external power supply and meets the monitoring requirements of spent fuel pool.
