This paper discusses a methodology to be used in evaluating existing coatings on buried piping in
nuclear power plants and selection of repair and remediation coatings. In many cases, the same
coating can be used for either repair or rehabilitation work.
Coatings for buried piping in nuclear power plant installations are selected based on accelerated
laboratory screening testing and in situ field testing of both existing coatings and soil conditions
surrounding the buried pipe.
Key words: buried pipe coatings, corrosion of buried pipe, nuclear power plants
