As reported by Platt's, at 12 PM Noon Central time today, Dominion's Kewaunee atomic reactor was permanently shut down. Last October, Dominion announced its intention to permanently close Kewaunee by mid-2013. Dominion had attempted to sell Kewaunee, but found no buyers. Platt's reports "CMS Energy -- which sold Palisades, its only nuclear station, to Entergy in 2007 -- had considered buying the plant, but decided against it because of low gas prices and investor pushback."
Arnie Gundersen of Fairewinds Associates, Inc points out that Kewaunee still had an operating license for another 20 years, but Dominion is unable to operate the reactor economically. Gundersen also points out that the 60-year SAFESTOR plan prior to decommissioning means Kewaunee will not be dismantled and cleaned up until about a century after it commenced operations, in 1973.
Duke Energy's announcement in recent weeks regarding the fatally cracked containment at its Crystal River, FL reactor, and today's final SCRAM at Kewaunee, are the first permanent shutdowns of commercial atomic reactors in the U.S. in about 15 years. Kewaunee joins Zion 1 & 2 in IL, and Big Rock Point in MI, on the list of reactors on the Lake Michigan shore permanently shut down. Point Beach 1 & 2 in WI, as well as Cook 1 & 2 and Palisades in MI, are reactors still operating on the Lake Michigan shoreline. Lake Michigan is a headwaters of the Great Lakes, 20% of the world's surface fresh water, and drinking water supply for 8 U.S. states, 2 Canadian provinces, and a large number of Native American First Nations.
While Kewaunee's welcome closure means reactor risks are now gone, and no more irradiated nuclear fuel will be generated, as the New York Times reports, decommissioning costs, and the challenges of managing the high-level radioactive waste that has already been generated on-site, are just beginning.
