Summary of 2015 and 2016 State-of-the-Fleet Assessments of Cathodic Protection Systems
Nuclear plants use cathodic protection systems to minimize corrosion of buried systems, structures, and components. This research examined the condition of these systems at eight nuclear plants in North America. Researchers used the results to identify best practices, lessons, and gaps in guidance and training.

Welding and Repair Technology Center: Thermite Welding/Pin Brazing of New Cathodic Protection Lead
Cathodic protection systems are necessary to maintain the integrity of buried piping systems in nuclear power plants. This study examined whether alternative methods for attaching electrical connections in cathodic protection systems (thermite welding and pin brazing) could yield the same quality as traditional installation at lower cost.

Field Guide: Inspection, Maintenance, and Troubleshooting of Sacrificial Anode Cathodic Protection Systems for Transmission Line Structures
Cathodic protection systems can help prevent corrosion of metal components by electrically linking them to a “sacrificial anode metal” that more easily corrodes. This field guide on inspection and maintenance of transmission line cathodic protection systems covers basic inspection procedures and pass-fail criteria, installation and sizing of sacrificial anode systems, general troubleshooting, and maintenance of […]

Data Mining of Buried Pipe Inspection Results Data
Since 2011, nuclear power utilities have aggregated more than 4,300 inspection results for buried and underground pipes into an EPRI-managed industry database. Data analysis indicated that buried pipes are in extremely good condition and that internal corrosion is a more significant concern for some systems. This report discusses these and other observations and conclusions.
