摘要: 为了研究高温、高压下核电站内两相流中所含粒子在管道发生沉积的现象,深入探究粒子对管道的冲蚀沉积机制,采用相似原理与近似模化方法,设计并搭建了能够捕捉核电管道系统实际运行中关键参数的实验台。对30 h弯管沉积实验结果进行分析可知,90°水平弯管的外壁以及内壁为沉积热点区域,外壁轴向角30°~45°区域为沉积量最大区域;Co元素在8 mm×8 mm×3 mm样片上的沉积量达1.98×10-10 g。研究结果可为核电站辐射剂量预测以及辐射防护提供参考数据。

Abstract: In order to study the phenomenon that the particles contained in the two⁃phase flow in the nuclear power plant are deposited in the pipeline under high temperature and high pressure, the mechanism of particle erosion on the pipeline is deeply explored. The similar principle and approximate modeling method are used to design and build a nuclear power pipeline. The experimental platform for the key parameters of the actual operation of the system.The results of the 30 h elbow deposition experiment show that the outer wall and inner wall of the 90° horizontal elbow are the sedimentary hot area, the outer wall axial angle of 30~45 degrees is the maximum sedimentary area, the maximum deposition of Co elements is 1.98×10-10 g on 8 mm×8 mm×3 mm sample. The results of this paper can provide data basis for radiation dose prediction and radiation protection of nuclear power plants.

Key words: Nuclear power, Co particles, Deposition test, Radiation protection, Dose prediction
