Cathodic Protection (CP) and grounding conflicts are not unique to nuclear steam electric stations (NSES), but are also experienced throughout the fossil fueled fleet. The more conventional fossil fueled fleet operators have a long history with operation and maintenance of CP systems with varying degrees of success, ranging from excellent to dismal. The keys to successful implementation and maintenance of CP systems in power plants are: 1. commitment to monitoring and maintenance, 2. excellent record keeping, and 3. management commitment to funding needed repairs and replacements in a timely manner. We in the nuclear industry do have a clear advantage in the area of quality record keeping. The same may not always be said for the fossil fueled fleet. However, record keeping is only one piece of the puzzle. As the NSES fleet continues to age, installed CP systems are nearing the ends of their useful lives, in some cases impressed current cathodic protection (ICCP) groundbeds and galvanic anode cathodic protection (GACP) system anodes have already failed due to anode consumption, or are now approaching failure. As many NSES facilities are now involved in the plant life extension process, this is an ideal time to assess the efficacy of existing CP systems, or to consider application of CP to buried plant piping (BPP) for those facilities that were not provided with CP at the time of construction.
