Cathodic protection has been used on underground radioactive waste lines at the Hanford Site for over 40 years. Studies were performed at the time the cathodic protection system was installed. A review of some of the historical studies and findings will be presented, including a description of the old cathodic protection system. In addition, a description of the new system, a typical cathodic protection installation, improvements of the new system over the old system, some operating experience with the new system, and recommendations will also be presented.
