All 104 nuclear reactors currently operational in the US have irreparable safety issues and should be taken out of commission and replaced, former chairman of the US Nuclear Regulatory Commission, Gregory B. Jaczko said.
The comments, made during the Carnegie International Nuclear
Policy Conference, are “highly unusual” for a current or former
member of the safety commission, according to The New York Times.
Asked why he had suddenly decided to make the remarks, Jaczko
implied that he had only recently arrived at these conclusions
following the serious aftermath of Japan’s tsunami-stricken
Fukushima Daichii nuclear facility.
“I was just thinking about the issues more, and watching as the industry and the regulators and the whole nuclear safety community continues to try to figure out how to address these very, very difficult problems,” which were made more evident by the 2011 Fukushima nuclear accident in Japan, he said. “Continuing to put Band-Aid on Band-Aid is not going to fix the problem.”
According to the former chairman, US reactors that received permission from the nuclear commission to operate for an additional 20 years past their initial 40-year licenses would not likely last long. He further rejected the commission’s proposal for a second 20-year extension, which would leave some American nuclear reactors operating for some 80 years.
Jaczko’s comments are quite significant as the US faces a mass retirement of its reactors and nuclear policy largely revolves around maintaining existing facilities, rather than attempting to go through the politically hazardous process of financing and breaking ground on new plants.
Though the US maintains a massive naval nuclear program, all of the country's current civilian reactors began construction in 1974 or earlier, and a serious incident at Three Mile Island in 1979, along with an economic recession, essentially caused new projects to be scrapped.
A modest revival of enthusiasm for nuclear power emerged in the early part of the last decade, leading to the construction of four reactors at existing facilities within the last three years, slated to be completed by 2020. Despite the lack of new projects, the US is still the world’s biggest producer of nuclear power, which represents 19% of its total electrical output.
Fittingly, Jaczko’s comments came during a panel discussion of the Fukushima incident, which has brought greater attention to aging US reactors - some of which were quite similar to the General Electric-designed models overwhelmed by the earthquake and subsequent tsunami in 2011.
In response to those comments, Marvin S. Fertel, president and chief executive of the Nuclear Energy Institute, told the Times that the country’s nuclear power grid has, is, and will operate safely.
“US nuclear energy facilities are operating safely,” said Fertel. “That was the case prior to Greg Jaczko’s tenure as Nuclear Regulatory Commission chairman. It was the case during his tenure as NRC chairman, as acknowledged by the NRC’s special Fukushima response task force and evidenced by a multitude of safety and performance indicators. It is still the case today.”
Since the first nuclear reactor went operational in the US, there have been very few fatal incidents at nuclear power facilities, though there were a number of high profile stories written over the inherent dangers of large nuclear reactors during the mid-1970s. One of the most recent incidents at a US reactor was in April of 2013, when an employee was killed at the Arkansas Nuclear One plant while moving part of a generator.
Jaczko served as chairman of the nuclear regulatory agency since 2009, and according to the Times resigned in 2012 following conflicts with colleagues. He was seen as an outlying vote on a number of safety issues, and had advocated for more stringent safety improvements during his tenure.
