摘要
介绍岭澳核电站二期反应堆压力容器(RPV)技术改进,包括采用堆芯一体化筒体和整体顶盖结构、控制辐照敏感元素含量、降低堆焊层材料钴含量、改进径向键材料和焊缝金属材料、增加辐照监督管数量等措施,并分析RPV技术改进对设备性能、工程建设和运行维修的影响及带来的优势。
The technology improvement for the reactor pressure vessel on Ling'ao Phase Ⅱ Nuclear Power Station is given. This paper presents the description of the integrated core shell, integral reactor pressure vessel top cover, the control of irradiation sensitivity element content, co resident content reduction, the improvement of radial support blocks material and the increase the quantity of irradiation surveillance program capsules. The advantage of these improvement and impacts on equipment performance, construction, operation and maintenance of Ling'ao Phase Ⅱ Nuclear Power Station is analyzed.
