Steam generators are critical nuclear plant components and their high performance is essential for maximum thermal output and in order to successfully attain design life. Our experienced and well-trained staff provides support in the periodic service and rehabilitation of worn components; they also provide inspections, analysis and tool repairs. Our team can determine current status, diagnose problems, and predict the service life of steam generators and associated systems. We also offer rehabilitation technology designed in our engineering laboratories or by assembling integrated teams with steam generator suppliers.
