At the service of steam generator maintenance

摘要

To perform eddy current inspection, tube plugging, tube sleeving activities and other maintenance, workers have to enter a steam generator primary channel head through the primary manway. Improved equipment can increase reliability, shorten outages and reduce exposure. New equipment can be the result of innovative design, or the foresight to transfer technology from another industrial application. Connecticut-based NES is one company whose work in steam generator servicing over many years has brought improvements in the US and more recently in Europe, South America and Asia.
