Japan’s nuclear export strategy struggles despite India deal
Reactor manufacturers falter, from Toshiba to Areva
Indian Prime Minister Narendra Modi, left, and Japanese counterpart Shinzo Abe reached a final agreement on the nuclear cooperation pact last November.
Japan’s push to increase exports of nuclear technology has been cooled by Toshiba’s Westinghouse problems, undercutting a pillar of Prime Minister Shinzo Abe’s economic growth strategy just as a pact with India comes into effect.
The Diet’s upper house approved a nuclear cooperation deal with India on Wednesday. India plans to boost its nuclear power production capabilities tenfold as economic growth fuels energy demand.
India and Japan began negotiations in 2010, reaching an agreement in November when Indian Prime Minister Narendra Modi visited Abe. Japan will revise related directives for its Nuclear Regulation Authority. India already greenlighted the pact, which takes effect once both countries notify each other of such approval. This could happen as early as July.
India has 22 nuclear plants in operation and five under construction, the International Atomic Energy Agency says. The country plans to source one-quarter of its energy from nuclear power by 2050.
“Population and economic growth will further strain energy supply and demand,” said Satoshi Shimizu of the Japan Research Institute. “There is a lot of room for Japan to export nuclear power.”
But Japan’s export efforts have not gone according to plan. In June 2016, the U.S. and India reached a basic agreement on a deal commissioning Toshiba’s American subsidiary Westinghouse Electric to build six nuclear reactors. Japan had rushed to finalize the pact with India since Toshiba would be involved in supplying parts, but Westinghouse’s bankruptcy protection filing in March has thrown the conglomerate into crisis.
More global headwinds buffet the industry. Severe delays in the construction of nuclear power facilities by France’s Areva have ballooned losses, with the French government now leading the company’s reorganization. Vietnam canceled nuclear energy plans in November due to financial reasons and local opposition.
“Conditions have changed due to Toshiba and other issues,” said Takeo Kitsukawa, a professor at Tokyo University of Science. “The first issue is how to get [nuclear reactor] manufacturers back on their feet.”
A separate document indicates that Japan will cease cooperation should India break a 2008 pledge, made by its foreign minister at the time, to suspend nuclear tests. India has maintained its moratorium on nuclear testing since 1998.
Japan’s opposition Democratic Party disapproves of the India deal because the provision halting cooperation is not included in the agreement itself, and thus may offer insufficient legal guarantees limiting nuclear technology exports to peaceful uses. Opposition parties also worry that India is not a member of the Treaty on the Non-Proliferation of Nuclear Weapons.
‘Korea should review current radioactive waste management to go nuclear-free
The South Korean government should rethink its current approach to radioactive waste treatment technologies before attempting to go nuclear free, a renowned American nuclear expert said. In an interview with The Korea Herald, Frank von Hippel, a professor at Princeton University, warned that the state-run Korea Atomic Energy Research Institute is working on technologies that have failed in all other advanced industrial countries. http://www.koreaherald.com/view.php?ud=20170607000727
Decommissioning of Monju Fast-Breeder Reactor Accepted by Fukui Governor

Fukui governor accepts decision to decommission Monju reactor
Fukui Governor Issei Nishikawa has ditched his opposition to the central government’s plans to decommission the Monju prototype fast-breeder reactor in his prefecture.
Nishikawa had criticized Tokyo for deciding to decommission the reactor in Tsuruga without offering adequate assurances to local residents about such a massive project.
But during a meeting held at the prime minister’s office in Tokyo early June 7, he said, “Decommissioning of the Monju fast-breeder reactor is inevitable.”
At the meeting, attended by relevant Cabinet ministers, the government presented Nishikawa with a basic policy to remove spent nuclear fuel from the reactor in five and a half years and complete decommissioning in 30 years.
Hirokazu Matsuno, the science and technology minister, explained that the basic policy includes a plan to transfer spent nuclear fuel outside the prefecture as demanded by Fukui prefectural authorities.
The government will soon formally adopt the basic policy on decommissioning. The Japan Atomic Energy Agency, which operates the Monju reactor, will then draft its own plan for the project.
The government decided to decommission Monju at the end of last year and was initially expected to present the basic plan in April. However, Nishikawa had been airing concerns about the decommissioning.

Fukui governor approves scrapping of Monju reactor
The governor of Fukui in central Japan has consented to dismantling the prototype fast-breeder nuclear reactor in the prefecture.
The Japanese government decided in December to scrap the Monju reactor over a period of 30 years, following a series of safety management problems. It cited rising costs.
Governor Issei Nishikawa had opposed the plan, expressing concerns about the safety of the dismantling process.
Nishikawa met with Chief Cabinet Secretary Yoshihide Suga and science minister Hirokazu Matsuno on Wednesday in Tokyo.
Matsuno explained the basic plan for scrapping the reactor. The science minister said spent nuclear fuel and sodium coolant would be moved out of the prefecture in future.
He also said the government will come up with a development plan for the host city of Tsuruga by the next fiscal year. He said this would make the city a hub of nuclear research and personnel training.
Governor Nishikawa said he confirmed the government’s basic plan for decommissioning and revitalizing the community. He said he had no choice but to accept the decommissioning. He emphasized that the process be carried out safely.
5 Workers Exposed to Radioactive Materials at Oarai Nuclear Research Facility in Ibaraki, Japan
22,000 becquerels measured in worker’s lungs
Sources at Japan’s science ministry have told NHK that up to 22,000 becquerels of radioactivity have been detected in the lungs of a worker accidentally exposed to radioactive materials at a nuclear research facility.
The worker is one of 5 who were exposed to the contaminants on Tuesday at the Japan Atomic Energy Agency’s Oarai Research and Development Center in Ibaraki Prefecture, northeast of Tokyo.
The workers were inspecting fuel storage containers when a bag containing a powdered radioactive substance tore open, spilling its contents and contaminating the men’s gloves and protective clothing.
The Agency had said at the time that up to 24 becquerels had been detected in the nasal passages of 3 of the workers.
The science ministry said the maximum level of 22,000 becquerels was logged when the workers were rechecked by a different machine.
The country’s Nuclear Regulation Authority secretariat says the nuclear material detected was plutonium 239.
All 5 men have been taken to the National Institute of Radiological Sciences in Chiba City, near Tokyo, for more detailed examinations.
The Executive Officer of the National Institutes for Quantum and Radiological Science and Technology, Makoto Akashi, says he has never heard of 22,000 becquerels being detected in a human body in Japan.
Akashi says the figure, if accurate, is quite high.
He says the impact on the worker’s health will vary depending on the type of nuclide that entered his body.

Expert points at possible complications
A medical expert says he thinks that the worker will survive the exposure but that he may have future health problems.
Keiichi Nakagawa, Associate Professor of the University of Tokyo, said that this is the first case in Japan where 22,000 becquerels of radioactivity has been measured in a human body.
Nakagawa said he assumes that the agency’s officials based their calculation on the worst case scenario of the worker continuing to be affected by radiation over the next 50 years without receiving any treatment.
He said 12 sieverts of radiation would be fatal as a single external exposure. But he said that the health impacts of an internal exposure would emerge over 50 years.
Nakagawa noted that in some cases, leukemia patients are exposed to a total of 12 sieverts of radiation during therapy.
He said that he expected that the worker will recover with treatment to expel the contaminants.
But the expert said if radioactive materials stay in the worker’s body for a long time, there is a possibility that he may develop pneumonitis that causes breathing difficulties or other conditions.

Workers exposed to radiation at facility
An accident at a nuclear research facility near Tokyo has led to 5 workers being exposed to radioactive substances. One was found to have 22,000 becquerels of radioactive contaminants in his lungs.
The 5 workers were inspecting fuel storage containers on Tuesday at the Atomic Energy Agency’s Oarai Research and Development Center in Ibaraki Prefecture.
A bag inside a container ripped open, spilling its contents of powdered plutonium, uranium and other material. The substances contaminated the men’s protective clothing and gloves.
On Wednesday, the agency checked the workers with a device that measures radiation emitted from the body.
The highest reading they detected was 22,000 becquerels of plutonium-239 in the lungs of one worker.
The exact level of his exposure remains unknown.
An agency official explained that this figure amounts to 12 sieverts of internal exposure over 50 years. The official did not rule out future health problems for the man in his 50s, who was reportedly closest to the bag when it ripped.
The agency gave the workers medical treatment to expel the contaminants, and then transferred them to the National Institute of Radiological Sciences in Chiba city for further checks.
The agency says the spill did not affect the environment outside the research facility.
The exact level of the 4 other workers’ exposure remains unknown.
The Nuclear Regulation Authority will examine the agency’s safety measures after it provides a report on the accident’s cause.

The revolving door- politician to nuclear lobbyist – UK former Energy Minister
Evening Standard 7th June 2017 Former Lib Dem energy minister Sir Ed Davey was today accused of “keeping quiet” about a paid job with a lobbying firm that represents the French energy giant he awarded an £18 billion deal.
The accusation came after Sir Ed sent voters in Kingston and Surbiton a summary of his career in an election leaflet. While the “CV” for voters in the key marginal said he had gone “back to consultancy” after losing his seat in 2015, it made no mention that he is working two days a month for MHP Communications, a company which specialises in influencing government policy on behalf of paying clients.
Among MHP’s clients is EDF, the French firm that struck a controversial deal to build the Hinkley Point nuclear power station in Somerset. The deal, overseen by Sir Ed as energy secretary in the Coalition, was attacked as poor value for the taxpayer by critics because it involved paying EDF nearly three times the current wholesale price of electricity in return for constructing and running the massive project. One expert called the contract the “worst deal I’ve ever seen”. http://www.standard.co.uk/news/politics/ed-davey-kept-quiet-on-election-cv-about-energy-lobbying-job-a3558901.html
