摘　　要：反应堆压力容器螺栓孔清洗机用于对压水堆核电站反应堆压力容器主螺栓孔的螺纹表面进行自动清洗、吸尘/水和抛光,以清除螺纹表面残留的防咬合剂及其他杂物,通过清洗,主螺栓孔可进行后续的视频检查及相关维修活动工作,以确保反应堆压力容器使用的安全可靠。通过使用清洗机进行反应堆螺栓孔清洗,还可显著降低现场维修人员辐射受照剂量,实现核电站辐射防护最优化的目标。文章主要介绍了该设备的研制方案和系统构成。实验结果表明该设备的清洗效果良好。Reactor pressure vessel（RPV） stud holes cleaning machine is used to auotomatically wash the surface of the stud holes of the pressurized w ater reactor（PWR）,to absorb the dust and the w ater after w ashing,to polish the holes,so the anti-seize lubricant and the other dirt can be cleaned.After cleaning,the video inspection and the maintenance can be performed latterly to ensure the safety and the reliability of the RPV.Besides,the radiation dose can also be greatly reduced by using the machine to achieve the optimization of the radiation protection.This paper presents the key techniques,the mechanical architecture and the control system.The experiment result show s the cleaning effect of the machine is successful.
