Evaluation of Coatings for Buried Piping in Nuclear Power Plants

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.
