Cathodic Protection Systems for the Mitigation of External Corrosion of Buried and Submerged Metallic Piping Systems at Nuclear Power Plants - Item No. 21434

Abstract

This standard presents accepted methods and practices regarding the use of CP for the control of external corrosion on buried or submerged carbon steel, stainless steel, gray cast iron, ductile cast iron, copper, and aluminum piping systems at nuclear power plants.

It is not intended for CP of pre-stressed concrete cylinder pipe (PCCP) or other reinforced concrete pressure pipes.

Additional guidance regarding the design, installation and testing of CP systems for PCCP and other reinforced concrete pressure pipes can be found in NACE SP0100, “Cathodic Protection to Control External Corrosion of Concrete Pressure Pipelines and Mortar-Coated Steel Pipelines for Water and Waste Water Service.”3 This standard may be useful at facilities other than nuclear power plants, which contain complex networks of buried or submerged piping, which may be composed of more than one material and may or may not be grounded.

This standard addresses the design of CP systems in nuclear power plants for new piping systems, existing coated piping systems and existing uncoated piping systems.
