摘要
反应堆压力容器堆内构件吊篮筒体制造过程中频繁出现加工变形超差,严重影响吊篮筒体的加工质量和核电项目的建造周期。对筒体变形的影响因素和超差原因进行分析,并提出筒体变形的控制措施,在后续核电厂项目吊篮筒体的加工过程中取得良好效果。对筒体设计方面的改进和调整提出建议,部分改进已在国产第三代核电机组—华龙一号吊篮筒体的设计中得到应用。
Severe oversize distortion frequently occurs in the manufacturing of the core barrel, which affects the processing quality of the core barrel and the construction period of nuclear power plants. This paper analyzes the effecting factors and causes of oversize distortion of the core barrel, and provides the measures to control the distortion, which achieves good results in the following manufacture of the core barrels. Moreover, the improvement and adjustment of the barrel design is provided and applied to the Hualong No.1 project which is the Chinese third generation nuclear power plant.
