U.S.A. - Experts on Fukushima: It Can't Happen Here
The report, issued by the American Nuclear Society's special committee on Fukushima, says that the meltdown was caused by a "catastrophe of monumental, unanticipated proportions," but says the Japanese response is a "complex story of mismanagement, culture, and sometimes even simple errors in translation."
"Given the backdrop of the situation, mistakes related to Fukushima Daiichi certainly should have been expected," it says. "However, there were serious problems with accident management and with risk communication and crisis communication that need to be examined."
In a New York Times op-ed published Friday, James Acton and Mark Hibbs, senior associates in the nuclear policy program at the Carnegie Endowment for International Peace, similarly condemned the Japanese response.
"The potential risks of tsunamis to nuclear power plants are well understood and a set of international standards has been developed to mitigate those risks," they wrote. "Despite Japan's history of tsunamis … Japan's nuclear regulator did not apply those standards."

Worldwide Nuclear Energy Expansion Continues
Worldwide nuclear electricity generating capacity is expected to increase between 44 percent and 99 percent by 2035, the International Atomic Energy Agency and the Organization for Economic Cooperation and Development Nuclear Energy Agency said in their joint biannual report on uranium resources, released this week.
Japan's decision to shut down all but two of its nuclear reactors in the wake of the nuclear accident at Fukushima Daiichi last year played in to Germany's decision to phase out nuclear by 2022, but has apparently not slowed plans in other parts of Asia. Nuclear energy will see the sharpest expansion in China, India, and South Korea, the agencies said in a release, as well as in Russia.
Gary Dyck, head of nuclear fuel cycle and materials at the International Atomic Energy Agency, told Reuters that the long-term impact of Fukushima on global nuclear energy production was a "speed bump... We still expect huge growth in China."
Capacity in East Asia will jump by 125 percent to 185 percent, according to the report.
Though China suspended new nuclear projects in the wake of Fukushima, it now appears that China will react to the incident by turning to newer, domestically produced nuclear reactors, Harvard research scholar Yun Zhou wrote last month.
"It appears that the Fukushima disaster may lead China to adopt newer, third-generation (or Gen III) reactor designs created by Chinese firms, allowing China to wean itself from purely foreign reactor technology much more quickly than was expected pre-Fukushima," she wrote. "In fact, a race to develop indigenous Gen III technology is emerging, with all three major nuclear power companies in China announcing their own Gen III reactor designs."

Obama taps Yucca Mtn critic to lead nuclear agency
By MATTHEW DALY, Associated Press
WASHINGTON (AP) — Moving quickly to stem a controversy, President Barack Obama on Thursday nominated an expert on nuclear waste to lead the federal agency that regulates the nation's nuclear power plants.
Allison Macfarlane, who served on a presidential commission that studied new strategies to manage nuclear waste, would replace Gregory Jaczko as head of the Nuclear Regulatory Commission. Jaczko announced his resignation Monday after a tumultuous three-year tenure in which he pushed for sweeping safety reforms but came under fire for an unyielding management style that fellow commissioners and agency employees described as bullying.
A White House spokesman said Obama believes Macfarlane is the right person to lead the commission, calling her a highly regarded expert who has spent years analyzing nuclear issues.
Macfarlane "understands the role that nuclear power must play in our nation's energy future while ensuring that we are always taking steps to produce this important energy source safely and securely," White House spokesman Clark Stevens said.
Stevens called the NRC crucial to protecting public health and safety and said Obama hopes the Senate considers her nomination quickly.
Macfarlane, 48, an associate professor of environmental science and policy at George Mason University in Fairfax, Va., wrote a book in 2006 that raised technical questions about a proposed nuclear waste dump at Nevada's Yucca Mountain.
Senate Majority Leader Harry Reid, D-Nev., who is the leading congressional opponent of the Yucca site, praised Macfarlane as someone who will make nuclear safety a top priority. Macfarlane's education and experience, especially her service on the blue-ribbon commission on nuclear waste, make her qualified to lead the NRC "for the foreseeable future," Reid said in a statement.
Reid said he continues to have concerns about Republican Kristine Svinicki, who has been nominated by Obama for a new term on the commission, but added that he believes Svinicki and Macfarlane should be considered together, continuing a recent Senate tradition of considering NRC nominees from opposing parties at the same time.
Svinicki, a nuclear engineer and former Senate GOP aide, was among four NRC commissioners who publicly criticized Jaczko's management style last year. The commissioners — two Democrats and two Republicans — sent a letter to the White House last fall expressing "grave concern" about Jaczko' s actions, which they said were abusive and "causing serious damage" to the commission.
No disciplinary action was taken against Jaczko, who has strongly denied the allegations.
Jaczko, a Democrat, announced his resignation ahead of a potentially blistering report due out soon from the agency's inspector general, which has been investigating Jaczko's actions for more than a year.
A former Reid aide, Jaczko led a strong response to the nuclear disaster in Japan and was a favorite of industry watchdogs, who called his emphasis on safety a refreshing change from previous agency chiefs who were close to the nuclear industry or who came from it.
But scientists, fellow commissioners and many rank-and-file staffers said Jaczko had created a chilled working environment at the NRC, which oversees safety at the nation's 104 commercial nuclear reactors.
The Nuclear Energy Institute, an industry group, called Macfarlane "an active contributor to policy debates in the nuclear energy field for many years" and urged the Senate to confirm her nomination as soon as possible.
"It would not serve the public interest to have her nomination linger," the group said. "We urge the Senate to confirm both Commissioner Svinicki and Professor Macfarlane expeditiously."
Sen. Barbara Boxer, D-Calif., chairwoman of the Senate Environment Committee, said Macfarlane's background and experience demonstrate a strong commitment to safety — a commitment she called especially important in the wake of the nuclear disaster at Japan's Fukushima Dai-ichi plant.
Boxer said she will schedule a joint hearing on the two NRC nominees in June.
Per Peterson, a professor of nuclear engineering at the University of California, served with Macfarlane on the nuclear waste commission, which was appointed by the Obama administration to make recommendations on how the nation should store and dispose of more than 71,000 tons of radioactive waste at dozens of sites across the country.
"I think she will be effective in leadership" of the NRC, "mainly because she listens," Peterson said of Macfarlane.
In a 2009 interview with Technology Review, Macfarlane acknowledged that most of the objections to the never-completed Yucca Mountain site were political, but added: "The technical objections are serious and real."
The area near Yucca Mountain is seismically and volcanically active, she said, adding that spent nuclear fuel could be stored safely at nuclear plants for decades.
The presidential panel recommended that the government start looking immediately for an alternative to Yucca Mountain. The report also recommended that responsibility for managing nuclear waste be transferred to a new organization, independent of the Energy Department.

Analysis: U.S. firms may miss out as Saudi nuke plan advances
Saudi Arabia has some of the world's largest oil and gas fields but rapidly rising power demand in the kingdom threatens to absorb much of those reserves unless it can find alternative fuels for its long-term economic growth.
Riyadh, which says electricity demand could soar from around 45 gig watts (GW) to 120 GW by 2035, commissioned the King Abdullah City for Atomic and Renewable Energy (KA-CARE) in 2010 to draw up a plan for reducing reliance on oil and gas.
It has signed nuclear cooperation deals with countries able to build reactors, including the United States, France, Russia, South Korea, China and Argentina. And Riyadh needs to move relatively quickly if it is to achieve its goal of opening its first nuclear plant by 2020.
"We expect the current consultation phase with the Council to last for a few more months before we can announce the Kingdom's energy sources, capacity targets, and milestone regulations," a KA-CARE spokesman said. "Soon we will be announcing what the energy mix for the reactors will be."
U.S. companies lost out to a lower-bidding Korean consortium in the first Gulf region nuclear plant tender in the United Arab Emirates (UAE) in 2009. They could be sidelined again until Washington and Riyadh sign a "123 agreement" under the U.S. Atomic Energy Act - opening the door for U.S. nuclear exports.
Nuclear projects tend to progress slowly - thanks to their size, complexity and many safety issues.
A U.S. embassy cable released by Wikileaks warned in 2009 that Saudi Arabia pressing ahead with one of the world's largest atomic energy programs without U.S. involvement was a "near-term risk to U.S. interests."
But with congress preoccupied with U.S. presidential elections and stopping Iran's nuclear program, which it suspects includes weapons development, it is unlikely any deal will be concluded this year.
"There's high doubt that President Obama or the U.S. congress, which needs to ratify the 123 agreement, will move on this in 2012," said a source in Washington familiar with U.S. energy policy.
"I think the Saudis will have to wait and see who wins the elections first before they proceed ... this may not be until 2014 before the United States considers it."
Riyadh, may not wait until 2014 for a U.S. non-proliferation deal and has several other options if the door to U.S. companies remains shut.
"It would constrain American suppliers of reactors or of services, like conversion or enrichment, but as far as anybody else is concerned, no," Ian Hore-Lacy, spokesman for the World Nuclear Association (WNA), a group representing nuclear power companies around the world, said.
"But there would be plenty of options. Even in a worst case scenario, there are still other avenues of buying equipment and services ... It certainly wouldn't be a show stopper," he said.
It is unclear how the use of some U.S.-patented technologies by other nuclear plant builders would be affected if the United States and the kingdom do not strike a 123 deal.
The UAE signed the 123 agreement with the United States in early 2009, forfeiting its right to enrich uranium domestically, before awarding a $40 billion contract to a Korean-led consortium later that year.
Prince Turki al-Faisal, a key Saudi royal, has said the kingdom would not surrender its right to enrich its own uranium for energy use in the long term, although it expects to have to import fuel in the medium term.
"Early economic studies have indicated that although Saudi Arabia is naturally rich with uranium, using that uranium in Saudi Arabian facilities to produce fuel for electrical generation will not be economically feasible in the foreseeable future," the KA-CARE spokesman said. "Importing fuel is preferable at this time."
While concrete construction plans remain far off, Saudi Arabia has signed memorandums of understanding (MOUs) with several countries with experience in building nuclear plants - including the United States, France, Russia, South Korea, China and Argentina - over the last few years.

Report: U.S. nuclear plants have lowest number of unplanned shutdowns in 2011
U.S. nuclear power plants in 2011 recorded the lowest number of unplanned shutdowns since 2005 and achieved near-record levels of reliability and safety performance, according to safety and operations data compiled by the World Association of Nuclear Operators (WANO) and the Institute of Nuclear Power Operations (INPO). The industry also reached record levels for industrial safety, placing it among the best industries in U.S. Bureau of Labor Statistics rankings.
U.S. nuclear plants recorded 62 unplanned shutdowns last year, three fewer than the decade-low 65 that occurred in 2005. The record-low number of unplanned shutdowns helped the plants achieve reliability levels on par with the high operational efficiency sustained throughout the past decade.
Unplanned shutdowns can result from severe weather or grid disturbances that trigger safety responses. In 2011, despite tornadoes in the Southeast, an earthquake and hurricane along the East Coast and flooding in the Midwest, U.S. nuclear plants posted a capability factor of 91.4 percent. Last year marked the 10th straight year that a median capability factor of at least 91 percent has been achieved. Capability factor measures the amount of time a facility is online and producing electricity. The industry’s record-high capability factor, 92 percent, was set in 2005.
“America’s nuclear energy facilities performed extremely well in the face of a host of natural challenges,” said Tony Pietrangelo, the Nuclear Energy Institute’s senior vice president and chief nuclear officer.
Since 1990, the U.S. nuclear energy industry has increased its electricity production nearly 40 percent, with 790 billion kWh generated in 2011 from approximately the same number of reactors.

U.S. nuclear reactors are safe
By Marvin Fertel, Special to CNN
(CNN) -- The massive earthquake and tsunami in Japan one year ago understandably raised questions about the safety of America's nuclear energy facilities. Americans should know that all U.S. nuclear energy plant safety systems have been verified by the companies operating them as well as deemed safe by the independent Nuclear Regulatory Commission.
Equally important, the industry is proactively applying lessons learned from Fukushima Daiichi and is making nuclear power, which provides 20% of America's electricity, even safer.
The nuclear energy industry is working with the Nuclear Regulatory Commission on the steps to be taken to enhance safety at America's reactors. To further strengthen the plants' ability to withstand extreme events, the commission will require U.S. facilities to install additional instruments to monitor the level of water in used reactor fuel storage pools and add protection from extreme natural events such as floods and earthquakes, no matter how infrequent they may be.
Nuclear energy facilities already have multiple emergency generators, battery banks, backup offsite power supplies, extra pumps and other equipment. But companies that operate America's 104 commercial reactors have added or ordered nearly 400 major pieces of equipment to supplement layers of safety at these facilities. Under a commitment made by all U.S. operators, the companies will buy additional equipment, such as portable generators and pumps, which can be used to provide power and water to cool the reactors and used fuel pools under any extreme scenario.
Additional backup equipment at America's reactors will add even more layers of protection to deepen the resources that operators can draw upon to ensure power can be delivered to critical safety systems no matter what causes an event.
Our industry is committed to continuous learning: checking and rechecking every safety measure to make sure nuclear energy facilities are safe at all times. After global operational or natural events, it is our responsibility to ask again: How can we be even safer?
The nuclear industry is, without hesitation, using what is being learned from Japan to improve safety. Within days of the Fukushima accident, the U.S. industry launched intensive inspections to evaluate the readiness of the operators and equipment to respond to events similar to what happened in Japan, including managing an extended loss of power for vital safety systems, and seismic and flooding challenges.
Another view: Our reactors are still vulnerable a year after Fukushima
The inspections confirmed assessments by the Nuclear Regulatory Commission and state-based task forces that nuclear energy facilities are safe and have identified key areas for near-term safety enhancements. Important operational and preparedness features at U.S. reactors, different from those in Japan, would have enabled them to maintain safety during earthquakes or extreme flooding. Nonetheless, the industry is forging ahead to make those enhancements.
In a recent CNN.com opinion piece, an organization criticized these actions, saying industry is "getting out ahead of the NRC" by launching its own safety initiative. We would have it no other way. It's in our industry's DNA to learn safety lessons at any opportunity and apply them where warranted at our facilities. That is why our industry and its own watchdog organization -- the Institute for Nuclear Power Operations -- was held up as a model for safety when the president's commission on the Deepwater Horizon accident was looking at other industries for the oil industry to emulate.
Public and worker safety is our industry's top priority. We constantly reevaluate our safety practices to see how they can be even stronger. We have embraced this challenge, and our industry is aggressively seeking out and applying the lessons from Fukushima to our operations.
America needs nuclear energy as part of a portfolio of electricity options that will power our economy for generations. It is a vital source of affordable, carbon-free electricity today and for the future. To continue to reap its benefits and move toward American energy independence, we must and we will ensure that nuclear energy facilities operate safely.
