Global expansion of nuclear power may draw more scrutiny after officials in China and India and U.S. lawmakers called for the review of atomic energy plans as Japan struggles with reactors crippled by a quake and tsunami.
Tokyo Electric Power Co.’s Fukushima Dai-Ichi No. 3 reactor experienced a hydrogen explosion at 11:01 a.m. local time today, Japan’s Ministry of Economy, Trade and Industry said. Residents living within 20 kilometers were ordered indoors, Kyodo reported. An explosion March 12 at the No. 1 reactor, 220 kilometers (135 miles) north of Tokyo, injured four workers.
The 8.9-magnitude temblor and subsequent tsunami that struck northeast Japan on March 11 cut power to the reactors’ cooling systems. Tokyo Electric engineers have been working to prevent the meltdown of the two units by flooding each with a mixture of water and boric acid to stymie a catastrophic release of radiation.
“This is obviously a significant setback for the so-called nuclear renaissance,” said Peter Bradford, a former member of the U.S. Nuclear Regulatory Commission. “The image of a nuclear power plant blowing up before your eyes on a television screen is a first.”
Tokyo Electric stock was untraded today and set to tumble by 24 percent, the daily limit, as sell orders overwhelmed those to buy.
Australian uranium companies slumped because of concerns the disaster may curb reactor fuel demand. Paladin Energy Ltd. (PDN) fell as much as 16 percent, heading for its biggest decline in more than 28 months. Energy Resources of Australia Ltd. dropped as much as 12 percent. Extract Resources Ltd. slumped 10 percent.
China may consider the effects of the nuclear accident as it completes its energy plans for the 2011-2015 period, Xie Zhenhua, vice chairman of the National Development and Reform Commission, said in Beijing yesterday. China is tripling the number of its reactors, building 27 units to add to the 13 now operating on the mainland, according to the World Nuclear Association.
“Evaluation of nuclear safety and the monitoring of plants will be definitely strengthened,” Xie said yesterday, while attending the closing of the Chinese People’s Political Consultative Conference.
India, which plans for a 13-fold increase in nuclear power generation, will reconsider its expansion as Japan’s worst accident in at least 33 years forces a safety review of existing and proposed plants, Nuclear Power Corp. of India said.
India to ‘Revisit’
“This event may be a big dampener for our program,” Shreyans Kumar Jain, chairman of India’s state-run monopoly producer, said in a telephone interview from Mumbai yesterday. “We and the Department of Atomic Energy will definitely revisit the entire thing, including our new reactor plans, after we receive more information from Japan.”
Germany’s energy agency Dena recommends a return to phasing out nuclear power and switching off reactors in the country that are similar to those crippled in Japan, the German newspaper Handelsblatt reported, citing an interview yesterday with the agency’s head Stephan Kohler.
There are 442 reactors worldwide that supply about 15 percent of the globe’s electricity, according to the London- based World Nuclear Association. There are plans to build more than 155 additional reactors, most of them in Asia, and 65 reactors are currently under construction, the association said on its website.
Japan gets about a third of its electricity from 54 nuclear power plants, the third-most after the U.S. and France. Two reactors are under construction and 12 more are planned, according to the association.
Three Mile Island
“Certainly it’s going to cause some reappraisals because this is what you call a ‘show-stopping’ event,” said Robert Alvarez, a senior scholar at the Washington-based Institute for Policy Studies and former senior policy adviser at the U.S. Energy Department.
U.S. utilities canceled 14 nuclear plant orders in the wake of the 1979 partial meltdown at the Three Mile Island reactor in Pennsylvania, according to the International Atomic Energy Agency. The “immense” psychological effect of the accident spread through the Western world, the agency said in a report.
“The arguments that held sway during the Three Mile Island days will hold sway today with this accident,” said Tom Cochran, a nuclear physicist at the New York-based Natural Resources Defense Council. “The situations are somewhat similar, assuming this doesn’t blow up or breach the reactor vessel.”
The U.S. should slow the construction of new domestic nuclear power plants until officials can assess whether the situation in Japan signals a need for additional safety measures, said Senator Joseph Lieberman of Connecticut, an independent who heads the Homeland Security Committee.
Twenty-three nuclear power plants in the U.S. were built according to designs that are similar to the Dai-Ichi plant’s, Lieberman said yesterday on CBS’s “Face the Nation.”
“I don’t want to stop the building of nuclear power plants, but I think we’ve got to quietly, quickly put the brakes on until we can absorb what has happened in Japan as a result of the earthquake and tsunami and see what more, if anything, we can demand of the new power plants that are coming online,” Lieberman said.
Still, Lieberman said he supports nuclear power because “it’s domestic and it’s ours and it’s clean.” U.S. plants have had a good safety record since safety standards were upgraded after the Three Mile Island accident, he said.
“The bottom line is, we do have to free ourselves of dependence from foreign oil in the other half of the globe,” Schumer said on NBC’s “Meet the Press” yesterday. “I’m still willing to look at nuclear. As I’ve always said, it has to be done safely and carefully.”
Those who advocate nuclear power, which emits virtually no carbon dioxide, as a way to combat climate change will now have to deal with a “greatly heightened skepticism” and “heightened unwillingness to have nuclear power plants located in one’s own neighborhood,” Bradford said.
The damaged Japanese Dai-Ichi No. 1 reactor, designed by General Electric Co. (GE), began commercial operation in 1971 and is similar to units still running in the U.S., said Cochran, who advised U.S. regulators on the cleanup of Three Mile Island.
Problems at the reactor may encourage the replacement of older models, said Sergei Novikov, a spokesman for Russia’s state-owned nuclear holding company Rosatom Corp.
“The global nuclear industry will speed up phasing out first-generation power units and start building new ones,” Novikov said.
Rosatom is building 15 new reactors worldwide, more than any other international supplier, five of them outside Russia.
GE, the largest U.S.-based reactor builder, is focused on the situation at the reactor in Fukushima and staff weren’t available to comment on the outlook for the industry, Michael Tetuan, a spokesman for the Fairfield, Connecticut-based company, said in an e-mailed message.
“In general, our business is going very well, but the situation in Japan is troubling,” said Vaughn Gilbert, a spokesman for Toshiba Corp. (6502)’s Westinghouse nuclear unit.
Patricia Marie, a spokeswoman for France’s Areva SA (CEI), declined to comment yesterday on the Fukushima situation or its effect on the nuclear industry.
The U.S. Nuclear Regulatory Commission is in talks with its Japanese counterparts, according to a press release. German Chancellor Angela Merkel and French Minister of Industry Eric Besson affirmed their nation’s confidence in the safety of nuclear power.
“We know how secure our power stations are,” Merkel told reporters in Berlin amid opposition calls for a rethinking of Germany’s use of nuclear power.
It’s too early to speculate on U.S. political and financial fallout from the accident in Fukushima, said Richard Myers, vice president for policy at the Washington-based Nuclear Energy Institute, which represents reactor owners and builders.
“We’ve been saying for five years now that we expect the renaissance of nuclear power would unfold slowly,” Myers said. “We expected to see between four and eight new nuclear reactors between now and 2020 and we still believe that.”
Preliminary construction has begun on new reactors in Georgia and South Carolina, where state regulators allow companies to recover the cost of reactors as they are built, he said.
Avoiding disaster in Japan may help the industry prove its ability to handle emergencies, said Dale Klein, a former U.S. Nuclear Regulatory Commission chairman and a professor of nuclear engineering at the University of Texas at Austin.
“As long as they keep the core covered, as long as there’s no significant radiation release, it will demonstrate that the safety systems for the most part worked,” Klein said. “The human disaster that will be remembered will be the earthquake and the tsunami, which will have caused many more deaths.”
