摘　　要：反应堆本体维护是核电机组换料大修必须要做的重要工作。由于反应堆本体中设备结构复杂、尺寸较大、维修工期紧张、辐射剂量率高,缺陷的测量检查、水下维修工装的安装定位等非常困难,无法应用常规技术进行测量检查。本研究采用先进的基于球坐标法的高精度激光测量技术并结合柔性工装,可实现在大型空间内水下远距离的精确测量,并对测量数据进行趋势分析,得到出现偏差的原因,为机组大修提供可靠数据支持,从而保证高辐射环境水下维修工作的顺利开展,确保核电厂安全、可靠、稳定运行。The maintenance of reactor body is an important work that must be done in refueling overhaul of nuclear power units.Due to the complex structure,large size,tight maintenance period and high radiation dose rate of the equipment in the reactor body,it is very difficult to measure and inspect defects and install and locate underwater maintenance tools,which cannot be measured and inspected with conventional techniques.In this study,advanced high-precision laser measurement technology based on spherical coordinate method combined with flexible tooling can realize accurate underwater long-distance measurement in large space.The trend of the measured data can be analyzed,and the reasons for the deviation are obtained,which can provide reliable data support for the overhaul of the unit,thus ensuring the smooth execution of underwater maintenance work in high radiation environment and ensuring the safe,reliable and stable operation of the nuclear power plant.
