Heat Exchanger/Condenser Asset Management
Heat exchangers and condensers, critical components in nuclear plant cooling systems, are necessarily exposed to a variety of water chemistries and operating conditions, and heat exchanger life in particular is limited by tube leaks, cracking, and ruptures, as well as heat transfer end-of-life when tube plugging limits are reached. This new SI Webinar discusses heat exchanger and condenser life limits; mandated inspections and controls; current approaches to extend tube life such as tube plugging, retubing, sleeves, modular replacements, and mid-span staking; and such improved approaches as heat exchanger-specific tube plugging criteria, pit propagation control, financial risk-based repair/replacement decisions, corrosion monitoring, and biofilm monitoring.
