CARR堆芯容器主筒体为反应堆冷却剂压力边界的一部分,它与膨胀节组件、重水箱组件等其它零件保证了压力边界的完整性。在本部分压力边界中,堆芯容器主筒体和膨胀节法兰、重水箱下封头底座连接处的密封为压力边界最薄弱的部分,所以,此处的密封结构和密封圈的性能就尤为重
The main core of the CARR reactor core is part of the reactor coolant pressure boundary, which assures the integrity of the pressure boundary with other components such as expansion joint components, heavy tank components and more. In this part of the pressure boundary, the seal between the main cylinder of the core vessel and the flange of the expansion joint and the base of the lower header of the heavy water tank is the weakest part of the pressure boundary. Therefore, the performance of the sealing structure and the sealing ring here Particularly heavy
