Attorney General Martha Coakley today filed an appeal of the Nuclear Regulatory Commission’s decision to relicense the Pilgrim Nuclear Power Plant for another 20 years, her office announced. The appeal, filed in the First US Circuit Court of Appeals in Boston, asserts that the NRC acted “arbitrarily” and “abused its discretion” when it voted to relicense the Plymouth power plant for another 20 years before considering the similarities between the Pilgrim plant and the Fukushima Daiichi power plant in Japan.
