 New York State is seeking to close Indian Point Nuclear Power Plant, in Buchanan, 30 miles from New York City, despite this reactor being the primary contributor to Vermont's green energy fund.The additional cancellation of five large reactor upgrades (Prairie Island, 1 reactor, LaSalle, 2 reactors, and Limerick, 2 reactors), four by the largest nuclear company in the U.S., suggest that the nuclear industry faces "a broad range of operational and economic problems".In July 2013, economist Mark Cooper named some nuclear power plants that face particularly intense challenges to their continued operation.
