Three Mile Island Unit 2 Licensing History

Three Mile Island Unit 2 (TMI-2) is the site of the most significant nuclear accident in U.S. commercial nuclear power history. Since the accident on March 28, 1979, TMI-2 has been undergoing cleanup activities designed to place the plant in a safe, stable, and secure postaccident configuration. At the completion of the cleanup program, the licensee, GPU Nuclear Corporation, will place TMI-2 in a configuration termed postdefueling monitored storage. A brief overview of the postaccident TMI-2 licensing history focusing on several key events, and a description of its impact on the regulatory process are presented.
