VERNON, VT - JANUARY 5: The Vermont Yankee nuclear power plant on the Connecticut River as seen from the New Hampshire side of the river January 5, 2004 in Vernon, Vermont. Democratic presidential front-runner Howard Dean is under fire for security lapses at the site during his tenure as governor of Vermont, including an incident in August 2001 when three mock terrorists gained access to the plant during a mock drill put on by the Nuclear Regulatory Commission, which gave Vermont Yankee the worst security rating of the nation's 103 nuclear reactors.
