The initial design life for most nuclear power plants is 40 years. Whether in continuous operation or only brought online during an event, the HVAC system as well as specialty heat transfer and barrier components are critical to maintaining safe, reliable, and efficient operation. Age, operating conditions, and the durability of components can lead to reliability concerns. With over 60 years of experience, Ellis & Watts is an industry leader in providing new and replacement HVAC systems and specialty components to owners and operators of these critical power plants. Further, as components age, Ellis & Watts has maintained the documentation, knowledge, and capabilities to provide replacements that are compliant with the original plant design requirements. For many utilities, this knowledge and expertise becomes invaluable as their own nuclear experts retire and take with them the knowhow necessary to maintain and extend the life of nuclear power plant support systems.
