The tough times the U.S. nuclear power industry faces today are only going to get worse. In the wake of nine major nuclear reactor closures or uprate cancellations in recent months, a review of the remaining U.S. fleet reveals that 38 reactors in 23 states are at risk of early retirement, with 12 facing the greatest risk of being shutdown, according to a major new analysis by Mark Cooper, senior fellow for economic analysis, Institute for Energy and the Environment, Vermont Law School.
Cooper is the author of several reports on nuclear power, including “Policy Challenges of Nuclear Reactor Construction, Cost Escalation and Crowding Out Alternatives” (2009).
“Renaissance in Reverse: Competition Pushes Aging U.S. Nuclear Reactors to the Brink of Economic Abandonment,” the new Cooper report, looks beyond the recent shutdown of four reactors – San Onofre (2 reactors) in California, Kewaunee in Wisconsin, and Crystal River in Florida – and the death of five large planned “uprate” expansion projects – Prairie Island in Minnesota, LaSalle (2 reactors) in Illinois, and Limerick (2 reactors) in Pennsylvania.
Using 11 risk factors – including competition from lower-cost energy sources, falling demand, safety retrofit expenses, costly repairs, and rising operating costs – identified in three different Wall Street analysis reports from Moody’s, UBS, and Credit Suisse, the Cooper report finds:
38 reactors in 23 states exhibited four or more of the 11 risk factors. The 23 states with at-risk nuclear reactors: Alabama (Browns Ferry); California (Diablo Canyon); Connecticut (Millstone); Florida (Turkey Point); Illinois (Clinton, Dresden, LaSalle, and Quad Cities); Iowa (Duane Arnold); Kansas (Wolf Creek); Maryland (Calvert Cliff); Massachusetts (Pilgrim); Michigan (Cook, Fermi, and Palisades); Minnesota (Monticello and Prairie Island); Missouri (Callaway); Nebraska (Cooper and Ft. Calhoun); New Hampshire (Seabrook); New Jersey (Hope Creek and Oyster Creek); New York (Fitzpatrick, Ginna, Indian Point, and Nine Mile Point); Ohio (Davis-Besse and Perry); Pennsylvania (Limerick, Susquehanna, and Three Mile Island); South Carolina (Robinson); Tennessee (Sequoyah); Texas (Comanche Peak and South Texas); Vermont (Vt. Yankee); and Wisconsin (Point Beach).
Of the overall at-risk group, 12 reactors (in alphabetical order) were found to be at greatest risk of early retirement: Clinton (selling into a tough market); Davis-Besse (large number of risk factors); Fitzpatrick (high cost but offset by high market clearing price); Ft. Calhoun (outage, poor performance); Ginna (single unit with negative margin, existing contract); Indian Point (license extension, state opposition); Millstone (tax issues); Nine Mile Point (site size saves it, existing contract); Oyster Creek (already set to retire early); Palisades (repair impending, local opposition) Pilgrim (large number of risk factors, local opposition); and Vt. Yankee (tax issue and state opposition).
Commenting on the report, Mark Cooper said: “Recent developments have sent what are truly shock waves through the industry and Wall Street. The spate of early retirements and decisions to forego uprates magnify the importance of the fact that the ‘nuclear renaissance’ has failed to produce a new fleet of reactors in the U.S. With little chance that the cost of new reactors will become competitive with low carbon alternatives in the time frame relevant for old reactor retirement decisions, we need to start preparing now for more early retirements or the threats of such retirements. By explaining the underlying economic causes of the growing wave of early retirements, the policymakers will be better equipped to make economically rational responses.”
Peter A. Bradford, adjunct professor at the Vermont Law School, a former member of the U.S. Nuclear Regulatory Commission (NRC), and a former utility commission chair in New York and Maine, said: “No U.S. nuclear plant has ever closed because it reached the end of its licensed life. Instead, cost challenges to their continued profitability have usually been the cause of shutdowns. Dr. Cooper's new work shows this to be a widespread and an enduring problem, one that further undermines nuclear power's claim to being a promising bulwark in a serious climate policy.”
With a large number of reactors poised on the razor’s edge of economic abandonment, the chances are high that any one of a number of the key factors – significant repair costs, retrofits to improve safety, stiff competition from lower-cost energy alternatives, rising costs of operation – will push the owners to retire the reactors early for economic reasons. As Cooper points out, the same factors call into question the economic efficacy of license extensions and reactor uprates.
