Nuclear power plant operators are chartered to provide safe, reliable, and cost-effective electricity to millions of homes. The reliability and long-term viability of nuclear plants as infrastructure investments is supported by numerous corrosion management programs, tools, and systems to meet this challenge after 20, 30, and even 40 years or more of sustained operation.
This paper highlights plant processes and systems where these programs are leveraged, driving corrosion and integrity concerns, inspection and monitoring plans, trending and forecasting tools, and long-term asset integrity investment considerations. This paper also presents continuous improvement opportunities for operators, service providers, consultants, and organizations seeking to meet long-term asset integrity management challenges for this vital component of our electric infrastructure.
Perspectives from multiple operating plants will be reviewed in this paper. This information will be relevant to other power plants or facilities with complex balance of plant infrastructures supporting heating, cooling, fueling, and related industrial operations and infrastructure.
