As reported by the New York Times, former U.S. Nuclear Regulatory Commission (NRC) Chairman Gregory B. Jaczko recently came to the realization that all U.S. atomic reactors have unfixable safety flaws, and should be shut down. He added, however, that "new and improved" so-called small modular reactors could take their place.
Jaczko thinks that perhaps none of the reactors that have received NRC rubber-stamps for 20-year license extensions will ever last that long, in reality, let alone an additional 20-year extension NRC is currently flirting with the idea of allowing (40 years of initial operation, plus two 20-year license extensions, adding up to 80 years of operations!).
Oyster Creek, NJ (a Mark I) is the oldest still-running reactor in the U.S., although it is already planned to close by 2019, ten years short of its 20-year extension. Dominion Nuclear has also announced the permanent shutdown of Kewaunee in WI next month, although it still have decades of permitted operations on its license.
Ironically, Jaczko himself approved many 20-year license extensions, including at Palisades in MI (opposed by NIRS and a state-wide environmental coalition) and Vermont Yankee (opposed by the vast majority of Green Mountain State residents and elected officials). Jaczko even voted to not hearing Beyond Nuclear's contentions at the Seabrook, NH and Davis-Besse, OH license extension proceedings regarding renewable alternatives, such as wind power, to the 20-year extensions at the dangerously degraded old reactors.
Jaczko reached out to Beyond Nuclear in May 2012 to set up a meeting between his entourage from NRC and concerned local residents and environmental group representatives near Palisades after he toured the problem-plagued reactor. During the closed-door meeting, concerned locals pressed Jaczko on why the 42-year-old, dangerously age-degraded reactor was allowed to operate. He responded, ironically enough, given his yes vote on Palisades' license extension in 2007, that once NRC grants an atomic reactor a license to operate, there is little that can then be done about it.
Jaczko did, however, earn the enmity of the nuclear power industry and his fellow NRC Commissioners, as by his past work against the proposed Yucca Mountain dumpsite, his invocation of emergency powers during the Fukushima nuclear catastrophe, and his votes against proposed new reactors in GA and SC because Fukushima "lessons learned" had not yet been applied or required. Although Jaczko often voted the industry's way, as above, he didn't always (often the sole dissenting vote), making him "insufficiently pro-nuclear" for the nuclear establishment, as Beyond Nuclear board member and investigative journalist Karl Grossman put it.
Jaczko was first appointed to the NRC Commission in 2005. In 2009, President Obama appointed him the chair the agency, which he did till 2012. He had previously worked on Capitol Hill, as a staffer for U.S. Sen. Harry Reid (D-NV), and as a science fellow for U.S. Rep. Ed Markey (D-MA), working on the Yucca Mountain and other nuclear power and radioactive waste issues.
