This project will focus on challenges in CANDU nuclear reactor steam generator (SG) inspection and maintenance that are not presently addressed by conventional inspection technologies. The advancement of transient eddy current (TEC) technology will target inspection issues associated with support plate degradation and fouling, which lead to tube corrosion and loss of SG efficiency. Inspection and monitoring of these conditions can be integrated with preventive maintenance programs, thereby enhancing station life management processes. Extension of the transient eddy current technique to other in-reactor tubular structures, such as fuel channel pressure tube to calandria tube gap and liquid injection shutdown system (LISS) nozzle proximity to calandria tube, will also be examined.

该项目将重点解决 CANDU 核反应堆蒸汽发生器 (SG) 检查和维护中目前传统检查技术无法解决的挑战。 瞬态涡流 (TEC) 技术的进步将针对与支撑板退化和污垢相关的检测问题，这些问题会导致管腐蚀和 SG 效率损失。 对这些状况的检查和监控可以与预防性维护计划相结合，从而增强电站寿命管理流程。 还将研究瞬态涡流技术扩展到其他反应堆内管状结构，例如燃料通道压力管到排管管间隙以及靠近排管管的液体喷射关闭系统（LISS）喷嘴。
