Entergy Corp. sued Vermont on Monday in a bid to keep the state's only nuclear-power plant running past March 2012.
The lawsuit, filed in federal court in Burlington, Vt., sets up a legal battle between the state, which has soured on the 39-year-old reactor, and the nation's second-largest nuclear operator after Exelon Corp. Entergy claims Vermont doesn't have authority over the plant, called Vermont Yankee.
This escalation in a long-running dispute comes amid heightened concerns about safety in the wake of the disaster at the Fukushima Daiichi nuclear plant in Japan after last month's earthquake and tsunami. Vermont Yankee's boiling-water reactor is the same model as those at Fukushima Daiichi.
But opposition to Vermont Yankee was already growing even before Japan's crippled plant started spewing radiation. Last year, New Orleans-based Entergy reported several instances of leaks of radioactive material from underground pipes at Vermont Yankee. Those safety concerns were coupled with accusations by Vermont officials that Entergy misled the state about the existence of underground piping.
