Recent operating experience from nuclear power plants, particularly those located in the United States, many of which are between 30 and 40 years old, indicates that degradation of buried piping is occurring in at least some plants and represents an issue requiring the attention of the nuclear industry. This NACE International technical committee report provides an overview of issues associated with buried piping in nuclear power plants that might be applicable worldwide. The report identifies issues for corrosion professionals to consider when addressing degradation of buried piping in nuclear power plants. It includes topics related to the external corrosion of buried piping, i.e., piping that is in direct contact with soil or concrete. It does not include topics related to internal corrosion of buried piping; corrosion of buried tanks, such as those in contact with soil, concrete, or underground piping; and tanks, i.e., those enclosed in a vault or trench.
