There is something surprising in the radioactive wreck that is the Fukushima Dai-ichi nuclear power plant: opportunity. To clean it up, Japan will have to develop technology and expertise that any nation with a nuclear reactor will one day need.
Eyeing dozens of aging reactors at home and hundreds of others worldwide that eventually need to be retired, Japanese industry sees a profitable market for decommissioning expertise.
It may sound surprising, given all the ongoing problems with the coastal Fukushima Dai-ichi plant, including massive leaks of contaminated water and other mishaps that followed its devastation by the March 2011 earthquake and tsunami.
However, many experts and industry officials say the experience and technology such as robotics being developed can be used in any decommissioning in the future. That could represent new opportunities for Japan Inc, which has lost some of its global clout to competitors from countries such as South Korea, China and the US.
“There is decommissioning business here beyond Fukushima and it’s a worldwide business,” said Lake Barrett, a former US nuclear regulator who headed the Three Mile Island cleanup.
“I think it’s an exciting new area,” he said. “Japan can be a world leader again.”
Japan’s government hopes an offshoot will a boom in the country’s nuclear technology exports.
Japan on Tuesday marks the third anniversary of the earthquake, tsunami and nuclear disasters that killed 15,884 people and left 2,636 unaccounted for in vast areas of its northern coast.
The country has struggled to rebuild tsunami-hit communities and to clean up radiation from the nuclear crisis, and has earmarked ￥25 trillion (US$250 billion) for reconstruction through March 2016.
About 50,000 people from Fukushima are still unable to return home due to concerns over radiation.
Despite the Fukushima meltdowns that experts say are far more challenging to deal with than the 1979 Three Mile Island meltdown, Japanese Prime Minister Shinzo Abe is eager to sell Japan’s nuclear plants and technology overseas.
He boasts that Japan can offer the world’s highest safety standards that reflect lessons learned from Fukushima.
More than 400 nuclear reactors are already in operation in more than 30 countries, with dozens more under construction. More new reactors are expected, including hundreds planned in China alone by 2050.
Tokyo Electric Power Co (TEPCO), the utility that runs Fukushima Dai-ichi, is setting up a separate company next month to clean up the plant.
Tentatively called the Decommissioning Company, it is overseen by the government’s economic ministry and could evolve into a decommissioning organization for other plants at home and abroad.
Academics, construction giants, electronics makers and risk management firms are rushing to get on the bus.
Japan also created the government-funded International Research Institute for Nuclear Decommissioning (IRID) last year.
It brings together nuclear plant operators, construction companies and organizations of nuclear experts to promote research and development of nuclear decommissioning technologies, as well as cooperation between international and domestic organizations.
IRID has received 780 proposals for funding from around the world for ideas and technologies related to the treatment and management of contaminated water, as well as 220 others about retrieving the three melted cores.
Japanese companies including Toshiba Corp, Mitsubishi Heavy Industries and Hitachi have been developing robots that can monitor radiation, decontaminate, remove contaminated debris or repair damage, and some of them have been mobilized at the plant.
Standard decommissioning has been largely carried out by human workers.
IRID managing director Kazuhiro Suzuki said the robotics technologies being developed to probe and remove Fukushima’s melted fuel could benefit ordinary decommissioning, not just severely damaged reactors.
Use of robotics and other advanced technologies not only helps to reduce worker radiation exposure, but could also make a cleanup faster and cheaper, said Barrett, who now advises TEPCO and IRID.
TEPCO is decommissioning four reactor units crippled by the 2011 earthquake and tsunami, and will later scrap the remaining two that survived.
Three suffered meltdowns and one was damaged by hydrogen explosions.
The decommissioning of the four would take about 40 years.
An Australian university student who has never visited China and has only a modest social media following would seem an unlikely target for the Chinese government. However, when a Chinese Ministry of Foreign Affairs spokesman personally denounced Drew Pavlou at a news conference, it was just the next phase in an extraordinary campaign against the 21-year-old that has fueled concerns over China’s targeting of critics overseas. Pavlou first placed himself in the superpower’s sights when in July last year he organized a small sit-in at the University of Queensland, where he studies, to protest against various Chinese government policies. Since then, the Global
‘ASKED TO MOVE OUT’: Indonesian coast guard personnel argued with a Chinese vessel over territorial claims after it entered the country’s exclusive economic zone An Indonesian patrol ship confronted a Chinese coast guard vessel that spent almost three days in waters where Indonesia claims economic rights and that are near the southernmost part of China’s disputed claims to the South China Sea. The Indonesian Maritime Security Agency on Friday night detected Chinese ship 5204 entering Indonesia’s exclusive economic zone (EEZ) in what Indonesia calls the North Natuna Sea. The agency sent a patrol ship that closed within 1km of the Chinese coast guard vessel and they communicated to affirm their position and their nation’s claims to the area, Indonesian Maritime Security Agency head Aan Kurnia said. “We
BEFORE WINTER COMES: Snow cuts off roads into Ladakh for four months or more each year, so the crunch is on to get food, tents and high-altitude equipment to Leh From deploying mules to large transport aircraft, the Indian military has activated its entire logistics network to transport supplies to thousands of troops for a harsh winter along a bitterly disputed Himalayan border with China. In the past few months, one of India’s biggest military logistics exercises in years has brought vast quantities of ammunition, equipment, fuel, winter supplies and food into Ladakh, a region bordering Tibet that India administers as a union territory, officials said. The move was triggered by a border standoff with China in the snow deserts of Ladakh that began in May and escalated in June into hand-to-hand
Since her personal telephone number was posted online, Hong Kong democracy advocate and Hong Kong Confederation of Trade Unions chairperson Carol Ng has received menacing calls from strangers and been bombarded with messages calling her a “cockroach.” She is not alone. A sophisticated and shady Web site called HK Leaks has ramped up its “doxxing” — where people’s personal details are published online — of Hong Kong democracy advocates, targeting those it says have broken Hong Kong’s National Security Law. Promoted by groups linked to the Chinese Chinese Communist Party and hosted on Russia-based servers, HK Leaks has become the most prominent “doxxing”
