The Senate Environment & Public Works committee vetted the reconfirmation of Nuclear Regulatory Commission chair Allison Macfarlane May 23. She\u2019s served in the post for one year. No final hearing on reconfirmation has been scheduled. \tThe re-nomination for a five-year term also became a forum for approving any trial restart of the San Onofre Nuclear Generating Station. \t\u201cI don\u2019t agree with you on how you\u2019re handling\u201d the potential restart of San Onofre, Sen. Barbara Boxer (D-CA) said to Macfarlane. The senator said she has \u201csleepless nights\u201d as a result of the lack of \u201cvigilant\u201d oversight in the potential San Onofre restart. Boxer noted that the commission has several paths of internal agency processes that conflict. One branch of the commission may allow start up while another continues to deliberate the matter. A third is an administrative judicial body that promises a full hearing on the restart (Current, May 17, 2013). \t On the other side of the issue, Sen. David Vitter (R-LA) said he is worried that there\u2019s a \u201cculture of hasty\u201d new domestic safety regulations in the wake of the 2010 Fukushima, Daiichi reactor meltdowns. He also focused on San Onofre. He added that the commission should not impose \u201cunnecessary and burdensome regulation\u201d on San Onofre prior to any restart. \tOther Republican senators stressed to Mcfarlane the cost of regulation to ratepayers. They declared that nuclear power plants are an inexpensive and carbon-free method of creating electricity. \t The committee noted that federal regulators have been under a Congressional microscope for years as they tight rope between promoting nuclear power and investing in the safety of nuclear plants. \tPresident Obama\u2019s re-nominee for Nuclear Regulatory Commission chair hails from academia instead of politics or the nuclear industry. Obama chose Macfarlane May 22, 2012, to succeed Greg Jaczko in the position. Jaczko was under intense scrutiny by Republicans in Congress for cracking down on domestic power plant safety after the Fukushima, Daiichi reactor meltdowns, as well as his management style at the commission. In addition to being an associate professor of environmental science and policy at George Mason University, she was a member of the Blue Ribbon Commission on America\u2019s Nuclear Future. That committee gave Congress its final report in January. She holds a Ph.D in geology from the Massachusetts Institute of Technology.
