In what some view as a harbinger of the difficult political task of relicensing the aging stock of 1970s era nuclear reactors nationwide, Vermont’s state Senate exercised its uniquely-held state relicensing authority to reject a plan to keep the Vermont Yankee plant open beyond 2012.

The vote came at a time of controversy for the plant itself, after recent concerns about tritium leaks have gone public and as activists, protestors and lawmakers expressed concerns over the plant’s safety. By contrast, the vote came just one week after President Obama announced the first $8 billion in an expected $50 billion of government-guaranteed loans for new nuclear reactors, a plan the White House said was essential to help meet America’s growing energy needs from sources that do not emit carbon dioxide.

Others, however, continue to vehemently oppose the idea of expanding nulcear power (or even relicensing the existing stock) on several fronts: safety of plant operation, national security, proliferation risk, unsolved waste disposal issues, and now, the financial gamble of guaranteeing loans to an industry that has a history of cost overruns and project delays.
