Two benchmark experiments were performed by NASA and CERL. The first was performed in 1998 at the NASA KSC Corrosion Technology Laboratory and the second in 2007 in Okinawa, Japan under the leadership of CERL.
Concrete repair is a neglected primary example of sustainable construction and green building practices. Sustainability in construction is a topic of increasing importance. Concrete has high embodied energy and much documentation exists about the sustainable nature of concrete in new construction. Concrete maintenance, protection, and repair are the ultimate acts of sustainability in construction because they preserve this embodied energy. Rating systems should be adopted to better capture the sustainable nature of concrete preservation
EPRI has been supporting the nuclear industry over the last several decades to provide the technical bases and research to support the operation of the current fleet of nuclear power plants beyond their initial licensing period (typically 30-40 years of operation). Hundreds of technical reports and guidance documents have been issued on topics ranging from developing and implementing aging management programs, identification, and evaluation of degradation mechanisms, and remaining useful life of key passive components (e.g., reactor vessel internals, cables, and concrete). A previous 2019 ANS Environmental Degradation Conference paper discussed the research goals and results of EPRI up to 2019 for concrete and cables. These research results provide a living technical basis as these results are supplemented regularly with industry operating experience, inspection results, and condition monitoring or non-destructive evaluations.
Many utilities around the world are pursuing long-term operation (LTO) of their nuclear power plants beyond the initial licensing period. In the United States, the majority of the renewed licenses have allowed the period of operation to be for up to 60 years and a few renewed licenses of up to 80 years of operation, with comparable efforts worldwide. Aging Management Programs (AMPs) are a key element in long-term operation of nuclear power plant and require effective implementation to ensure long-term safety and reliability of vital systems, structures, and components (SSCs). Typically, aging management implementation strategies have been focused on near-term obligations, and these may not be optimal for accomplishing longer-term reliability and sustainability objectives. Therefore, to optimally manage the potential impacts of aging, risk insights can be leveraged using a consistent and sustainable Framework that would focus on high-value actions while reinvesting knowledge and resources. This would allow the implementation of AMPs to enhance and optimize inspection, repair, and mitigation activities.
