控制棒位置传感器检测装置容器设计研究

Development of Detection Device Pressure Vessel for Control Rod Position Sensor in Nuclear Power Plants

针对田湾核电厂步长式控制棒位置传感器结构特点和检测装置容器功能需求完成容器的方案设计,明确容器主要由上封头、筒体、下封头组成。按照标准和工况要求,完成容器本体设备筒体和上下封头的强度计算和开口补强;同时对非标法兰支座进行了强度计算,综合计算结果完成了容器的校核,确保容器能够形成压力边界,密封工作介质,达到维持工作压力和温度的目的。

The pressure vessel design scheme was completed based on the structure features and function requirements for the step-type control rod position sensor of Tianwan Nuclear Power Plant. The pressure vessel was mainly formed by the upper head, the cylinder body and the lower head. According to standards and working conditions, the strength calculation and the opening reinforcement of the vessel body device for cylinder body, the upper and lower head was completed. At the same time, the strength calculation of the non-standard flange supports was completed, and then the verification of the vessel was completed based on the results of strength calculation, to ensure that the vessel can form a pressure boundary and seal the working medium to achieve the purpose of maintaining the working pressure and temperature.
