Experiment Research on Sludge Collector for Steam Generator

National Key Laboratory of Bubble and Natural Circulation, Research Institute of Nuclear Power Operation, Wuhan, 430074, China

摘要: 泥渣收集器是对蒸汽发生器二次侧泥渣进行主动管理的重要手段之一。以百万千瓦级压水堆核电厂为应用背景,对其蒸汽发生器进行了冷态实验,研究了泥渣收集器的结构、流量等因素对其性能的影响。试验结果表明,该泥渣收集器的收集效率可以达到50%以上,能够收集较宽粒径范围内的泥渣颗粒,具有良好的泥渣收集能力。
