摘要： A chimney lattice is arranged in a reactor pressure vessel. Thermocouple extension wire pulling conduits inserting a temperature detection thermocouple and a cable connected to the thermocouple are mounted to the upper end of the chimney lattice. By mounting the thermocouple extension wire pulling conduit on the upper end of the chimney lattice, the thermocouple extension wire pulling conduit does not become an obstacle when the fuel assembly is taken out from the chimney. Because the thermocouple extension wire pulling conduit is installed at the upper end of the chimney, the replacement of the thermocouple damaged is easy.
摘要翻译：烟囱格子布置在反应堆压力容器中。插入温度检测热电偶和连接到热电偶的电缆的热电偶延长线牵引导管安装在烟囱格栅的上端。通过将热电偶延长线拉出管道安装在烟囱格栅的上端，当燃料组件从烟囱中取出时，热电偶延长线拉拔管道不会成为障碍物。由于热电偶延长线拉拔管道安装在烟囱的上端，所以热电偶损坏的更换变得容易。
