Nuclear powerU.S. nuclear industry faces a wave of nuclear power station retirements
A wave of U.S. nuclear power station retirements is on the horizon. The typical design life of a nuclear power plant is 40 years. There are 104 nuclear power plants in the United States, and their average age is 34 years — only a few years short of, and fast approaching, their design life. Almost 30 U.S. commercial and research reactors already have started decommissioning. A $400 million is regarded as the bargain basement price tag for cleaning up a single reactor.
Mention “high costs,” “financing,” and “safety” in the same sentence as “commercial nuclear power plants,” and most people think of the multi-billion-dollar construction or operational phase of these facilities, which provide 20 percent of U.S. electric supply. Those concerns, however, are now emerging as aging nuclear power plants reach retirement age, and electric utilities confront the task of deconstruction, or decommissioning, nuclear power stations. This is the topic of the cover story in the current edition of Chemical & Engineering News, the weekly newsmagazine of the American Chemical Society (ACS).
An ACS release reports that in the article, Jeff Johnson, C&EN senior correspondent, explains that a wave of nuclear power station retirements may be on the horizon. The average age of the 104 nukes in the United States, for instance, is thirty-four years — only a few years short of and approaching their design life of forty years. Almost thirty U.S. commercial and research reactors already have started decommissioning.
The article describes why decommissioning is a long, complex, costly process, with $400 million regarded as the bargain basement price tag for cleaning up a single reactor. It includes an informative sidebar, “Anatomy of a Decommissioning,” describing why decommissioning is a big-ticket item, with special technologies and personnel needed for a safe retirement. Indeed, the coming wave of retirements likely will foster the emergence of a new industry devoted to decommissioning.
