Design and Verification of Integrated Measurement Instrument for NPP Spent Fuel Pool
-
摘要: 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。Abstract: The design of an innovative and integrated instrument device for level and temperature measurement in the spent fuel pool of nuclear power plants has been proposed based on the environment and functional requirement of spent fuel pool. The validation of the prototype device has been implemented and it is demonstrated that the accuracy and response meet the specifications for the spent fuel pool monitoring, with enhanced capability to monitor the level and temperature even under the station blackout accident.
