ABSTRACT
Nuclear steam generator chemical cleaning has been under development for two decades and is rapidly gaining acceptance by the nuclear industry as a long-term remedy for steam generator thermal/hydraulic performance degradation. The Three Mile Island Unit 1 (TMI-1) steam generator chemical cleaning performed by B&W Nuclear Technologies (BWNT) restored the unit to 100% power operation (previously limited to 96% power). Galvanic and general corrosion of steam generator components was monitored throughout the process, and was well within established limits. This paper describes the TMI-1 chemical cleaning program, the associated corrosion monitoring, and the specific and innovative developments that contributed to the success of the cleaning.
