      The Three Mile Island site was decontaminated to the extent possible and sealed off. But some damaged fuel from the reactor vessel remains, as well as an unknown amount of radioactive material. AmerGen, now Exelon, purchased the neighboring TMI Unit 1 reactor in , operating the facility until September, when Exelon shuttered the plant.

“TMI 25 Years Later provides a concise and objective overview of the causes and consequences of the Three Mile Island accident. Having played a role in the events the authors describe, I am impressed by their coverage of everything from reactor operation and regulation to effects on the surrounding community and the ten-year cleanup by: Comments were given on the financial and operational aspects of the cleanup effort at the Three Mile Island (TMI) nuclear powerplant and the potential impact that federal research and development funding could have on the total cost.

The latest estimate by the General Public Utilities Corporation (GPU) anticipates that $ million will be needed during the period.

For five days, the citizens of central Pennsylvania and the entire world, amid growing alarm, followed the efforts of authorities to prevent the crippled plant from spewing dangerous quantities of radiation into the environment. This book is the first comprehensive account of the causes, context, and consequences of the Three Mile Island by:   The TMI-2 Cleanup: Challenging and Successful The cleanup of the damaged nuclear reactor system at Three Mile Island Unit 2 took nearly 12 years and cost approximately $ million.

The cleanup was uniquely challenging technically and radiologically. Plant surfaces had to be decontaminated. Three Mile Island Cleanup The cleanup effort lasted 14 years and cost an estimated 1 billion dollars. The damaged reactor was permanently closed and entombed in concrete after the accident.

About the Collection. The Pennsylvania State University Libraries have acquired several thousand videotapes, reports, and photographs that were generated during the successful cleanup and recovery of the Three Mile Island Unit 2 (TMI-2) nuclear reactor. The safe, expeditious recovery and cleanup of Three Mile Island Unit 2 (TMI-2), including removal of the fuel from the accident-damaged reactor, were necessary for the long-term protection of public health and safety and the environment.

The cleanup campaign ensured that the TMI site did not become a long-term or permanent waste repository. The cleanup at the Three Mile Island nuclear plant has ended after 14 years with a final puff of radioactive steam from the evaporator used to get rid of contaminated water from the accident.

A failure in either the mechanical or electrical system — combined with a pilot-operated relief valve that workers were not able to close — led to a significant nuclear accident. The accident at Three Mile Island Unit 2 severely damaged the reactor core.

During the accident the pilot upper relief valve or pur located at the top of the pressurizer stuck open.

This allowed water in the form of steam to flow from the cooling system to a drain tank and eventually to the reactor building basement floor.
