Nuclear reactors at Fukushima No 2 plant to be decommissioned
Tepco says it will decommission nuclear reactors at Fukushima No. 2 plant https://www.japantimes.co.jp/news/2019/07/24/national/tepco-says-will-decommission-nuclear-reactors-fukushima-no-2-plant/#.XTjRFugzbIU, 24 July 19,
Tokyo Electric Power Company Holdings Inc. will decommission the Fukushima No. 2 nuclear plant, its president, Tomoaki Kobayakawa, told Fukushima Gov. Masao Ochibori at a meeting Wednesday.
The facility is the second nuclear plant that the utility company has decided to decommission after accepting it would need to shutter the nearby Fukushima No. 1 plant, which was crippled by the March 2011 earthquake and tsunami disaster in the world’s worst nuclear crisis since Chernobyl.
Tepco’s decision to scrap Fukushima No. 2, which is expected to cost some ¥280 billion ($2.6 billion), will be formally approved at the company’s board meeting later this month if local municipalities accept the plan.
The prefecture has demanded the utility scrap the reactors at Fukushima No. 2, saying their existence would hamper its reconstruction efforts. The plant has been offline since its operations were suspended due to the 2011 disaster.
If the plan goes ahead, all 10 nuclear reactors in the prefecture — four at the No. 2 plant and six at the No. 1 facility — will be scrapped.
It will also leave the utility company with only the Kashiwazaki-Kariwa nuclear plant in Niigata Prefecture and the planned Higashidori nuclear plant in Aomori Prefecture.
Kobayakawa said at the meeting, also attended by the mayors of the two towns — Naraha and Tomioka — that host the plant, that Tepco plans to build a new on-site storage facility for spent nuclear fuel from the reactors at the Fukushima No. 2 plant.
The fuel will be placed in metallic containers and cooled using a dry storage approach, according to the operator.
No decision has been made regarding final disposal of the spent fuel, raising concerns that the radioactive waste may remain on-site for a long time.
The Fukushima No.2 plant currently has around 10,000 assemblies of spent fuel cooling in pools.
40 years, $2.5bn costs for 4 Fukushima Daini nuclear reactors to be shut down
Tepco to retire remaining reactors in Fukushima https://asia.nikkei.com/Business/Companies/Tepco-to-retire-remaining-reactors-in-Fukushima Decommissioning is expected to take 40 years and cost $2.5bn TOKYO — Tokyo Electric Power Co. Holdings will scrap the four Fukushima Prefecture reactors that escaped damage in the 2011 earthquake and tsunami, moving to decommission all of the nuclear power plants the public utility owns in the disaster-stricken region.
The shutdown of the Fukushima Daini plant, which is located just 12km away from the Daiichi Plant crippled by fuel meltdowns, will be formally authorized at the company’s board meeting at the end of the month. This marks the first decision by the utility, known as Tepco, to decommission nuclear reactors apart from the Daiichi facilities.
Costs for decommissioning Fukushima Daini are estimated to exceed 270 billion yen ($2.5 billion). While Tepco’s reserves are not enough to cover them, the government adopted new accounting rules allowing operators to spread a large loss from decommissioning over multiple years. The company also believes it has secured enough people with necessary expertise to move forward.
Tepco soon will inform Fukushima Gov. Masao Uchibori of its decision. The utility intends to submit the decommissioning plan to Japan’s Nuclear Regulation Authority by March next year.
The decision means all 10 reactors in Fukushima will be scrapped. The Daini reactors will be decommissioned in roughly 40 years, sharing the same timetable as the Daiichi site. Tepco owns one other nuclear plant, the Kashiwazaki-Kariwa facility in Niigata Prefecture.
The Daini plant, where each reactor produced 1.1 gigawatts of power, served the Tokyo area for about three decades. Japan’s central government sought to restart the complex but faced withering opposition from local residents in Fukushima.
Including the Fukushima Daini facilities, a total of 21 reactors across Japan are now slated for decommissioning. Recent additions include two units at the Ikata plant in Ehime Prefecture and one reactor at the Onagawa facility in Miyagi Prefecture.

The unpleasant reality behind the Tokyo Olympics’ shimmering curtain of propaganda
Is Tokyo Ready for the Olympic Juggernaut? Tokyo says that it’s ready to host the 2020 Olympics. The early numbers—and quality of Olympic leadership—are not encouraging. The Nation, By Dave Zirin and Jules Boykoff 18 July 19
Dave ZirinTWITTERDave Zirin is the sports editor of The Nation.
Tokyo Electric Power Company to close down Fukushima Daini nuclear plant
The decommissioning of all four nuclear reactors at Daini will likely require more than 40 years and some 280 billion yen ($2.6 billion) in costs, the source said. If realized, all 10 nuclear reactors in Fukushima Prefecture will be scrapped.
Closure of the Daiichi plant, which suffered core meltdowns at three of its six reactors, has already been decided.
After telling Fukushima Gov. Masao Uchibori about the policy, it may be formally approved at a TEPCO board meeting, scheduled at the end of this month, the source said.
The Daini complex was also hit by tsunami waves in the 2011 disaster and temporarily lost reactor cooling functions. But unlike the Daiichi plant, it escaped meltdowns.
Since the disaster, the decommissioning in Japan of 21 nuclear reactors, including those at Daini, has been decided.
For the Tokyo-headquartered power company, the Kashiwazaki-Kariwa plant in Niigata Prefecture will be its only nuclear complex.
In June last year, TEPCO President Tomoaki Kobayakawa told the governor that the company is leaning toward scrapping all four reactors at the Daini plant. A project team was later formed at the utility and looked into whether that is possible, according to the source.
The prefecture has demanded the utility scrap the reactors, saying their existence would hamper its reconstruction efforts.
Japan’s nuclear industry has a doubtful future
Is there a future for nuclear power in Japan?, Japan Times, BY SUMIKO TAKEUCHI, JUL 16, 2019, This is the third in a series of reports on Japan’s energy policy…….
the damage from nuclear accidents can be catastrophic, in addition to the challenges posed by nuclear waste disposal. The Fukushima disaster has led to strong opinions that Japan should denuclearize, and this is still the case.
…. ………The fact is that the economic benefits of nuclear power have been losing their shine. Because of the sharp hike in safety standards imposed by the Nuclear Regulation Authority after the Fukushima disaster, exorbitant safety upgrades nearly equal in cost to building a new reactor are being installed at each site. To get a return on investment, this intensive capital spending will require long-term operation and high utilization rates, but the need to get local consent to operate and to respond to dozens of lawsuits from anti-nuclear residents is making stable operations difficult. Reactor operations are also capped at 60 years. Nuclear power could potentially be a source of cheap electricity, depending on the utilization rate and other conditions, but there’s also a possibility it won’t. ……
The impact of the Fukushima disaster, however, was enough to completely overshadow the benefits. The majority of the public is still against nuclear power. In light of persistent public opinion, Japan’s nuclear power business has been surrounded by three big uncertainties.
The first is political uncertainty. The administration of Prime Minister Shinzo Abe, despite its long-term stability, has not provided enough support to the nuclear power business. In addition, the government has entrusted the utilities with the job of gaining local consent.
The safety agreements that stipulate the rules of the industry, such as disclosure of information to the host governments, are not legally binding. But running reactors would be next to impossible without local consent based on such agreements. Whenever there’s an election, the utilities are thrown into confusion, and if a new leader is elected, they will initiate communication from scratch.
The second is policy uncertainty. Japan has fully liberalized the retail power sector. In a liberalized market, reactors for which returns on investment have fully recovered could have high cost competitiveness, but there will likely be no companies that will take up the challenge of building new ones.
Since nuclear plants require huge capital, curbing fundraising costs to a low level would have a big impact on competitiveness, but cheap fundraising is something that cannot be expected in a liberalized market. …….
The third is regulatory uncertainty. It has become quite common for reactor safety reviews to take multiple years because of inadequate communication between utilities and regulators. The U.S. has a presidential executive order that stipulates regulation shall not be undertaken unless the potential benefits to society from regulation outweigh the potential costs of dealing with the regulation.
Though Japan has no such principles, appropriate oversight on regulatory activities is being called for to check whether the public is suffering from any disadvantages from unforeseeable regulatory activities. In the meantime, the finishing blow is the plethora of lawsuits that have been filed demanding the halt of nuclear power plants……..
When utilities are placed in such an uncertain environment, it is a foregone conclusion that the nuclear power business will become unsustainable and there will be no future for it in Japan…..https://www.japantimes.co.jp/news/2019/07/16/business/future-nuclear-power-japan/#.XS-PhOszbGg

Fukushima Prefecture Council election: both candidates campaign on anti-nuclear platforms
Fukushima Upper House candidates face cynical voters despite anti-nuclear platforms, Japan Times, 14 July 19, JIJI FUKUSHIMA – Rival candidates, both women, from the ruling Liberal Democratic Party and the opposition camp for next Sunday’s House of Councilors election in Fukushima Prefecture are campaigning on platforms to eliminate nuclear power from the prefecture.
But their calls are in conflict with the national energy policy of the LDP and the positions of some opposition supporters.
With campaigning in the single-seat prefectural constituency shaping up effectively as a one-on-one race, local voters who were affected by the March 2011 nuclear accident are casting a cynical eye at the race for the July 21 election.
“I’m determined to push ahead with reconstruction following your requests,” Masako Mori, the LDP’s candidate for Fukushima, said on July 4, the opening day of the official campaign period, in the prefectural capital of Fukushima.
“I’ll do my best to achieve the goal of decommissioning all nuclear reactors in the prefecture,” said Mori, 54, vice chair of the LDP’s Headquarters for Accelerating Reconstruction after the Great East Japan Earthquake.
Prime Minister Shinzo Abe, also president of the LDP, gave a speech in support of Mori.
Reflecting local voter concerns over nuclear power, the LDP’s Fukushima chapter has set goals of scrapping all reactors in the prefecture and building up knowledge and expertise related to decommissioning.
In contrast to the prefectural chapter’s position, however, the Abe government’s basic energy program regards nuclear power as an important base load electric power source, while the LDP’s policy pledges for the Upper House election include efforts to reactivate nuclear reactors.
The LDP suffered losses in recent national elections in Fukushima Prefecture, home to Tokyo Electric Power Company Holdings Inc.’s Fukushima No. 1 nuclear power plant, the site of the nation’s worst-ever nuclear accident, which resulted from the March 2011 earthquake and tsunami………
Hard to differentiate
Mori’s key opponent in the three-way race is Sachiko Mizuno, 57, who is running as the opposition camp’s unified candidate.
On June 30, standing in drizzling rain in front of a department store in the city of Fukushima, Mizuno told a small crowd, “Reconstruction of Fukushima is still only half done.”
Referring to the LDP’s policy pledge, she said the government “has not presented a road map for decommissioning all reactors (in the prefecture).”……..
With Mizuno calling for a society free of nuclear power, the policy differences with the LDP are blurred. “It’s difficult to differentiate ourselves (from the LDP) in the prefecture,” a senior official in Mizuno’s campaign office said.
Within her camp, there are differing levels of enthusiasm regarding the elimination of nuclear power…….
Unenthusiastic voters
After the triple meltdown accident, the government issued an evacuation advisory to 11 municipalities around the stricken nuclear plant. Since the advisory was lifted in the eastern part of the city of Tamura in April 2014, the size of the exclusion zone has been reduced in stages.
But the advisory remains in place in the town of Futaba, as well as in parts of six municipalities, including the towns of Okuma and Namie. More than 30,000 people still live as evacuees outside the prefecture…….
In Namie, more than two years after the evacuation advisory was lifted for most of the town in March 2017, just over 1,000 people have returned. Of people who are still registered as residents of areas for which the advisory was removed, only some 7 percent have returned. ……..https://www.japantimes.co.jp/news/2019/07/14/national/politics-diplomacy/fukushima-upper-house-candidates-face-cynical-voters-despite-anti-nuclear-platforms/#.XSucHD8zbGg
A Fukushima Ghost Town Seeks Rebirth Through Renewable Energy
A Fukushima Ghost Town Seeks Rebirth Through Renewable Energy
Devastated by Japanese nuclear plant’s meltdown in 2011, Namie hopes a new hydrogen-fuel facility can generate a turnaround. WSJ, By River Davis, July 12, 2019
NAMIE, Japan—Fukushima prefecture, a place synonymous in many minds with nuclear meltdown, is trying to reinvent itself as a hub for renewable energy.
One symbol is just outside Namie, less than five miles from the nuclear-power plant devastated by an earthquake and tsunami in 2011. At the end of a winding road through miles of barren land, construction is nearing completion on one of the world’s largest hydrogen plants.
The government hopes to show that hydrogen, a hard-to-handle fuel that hasn’t been used for large-scale power generation, can supplement intermittent solar and wind power.
……….. By 2040, Fukushima aims to cover 100% of its energy demand with non-nuclear renewable energy. Since 2011, the prefecture’s generating capacity from renewable energy, excluding large-scale hydropower, has more than quadrupled. More than a gigawatt of solar-energy capacity has been added—the equivalent of more than three million solar panels—while other projects are under way in offshore wind power and geothermal energy……… https://www.wsj.com/articles/a-fukushima-ghost-town-seeks-rebirth-through-renewable-energy-11562923802
Circular flow of 2011 Fukushima cesium through Pacific, back to Japan
July 8, 2019 (Mainichi Japan) TOKYO — Radioactive cesium released into the Pacific Ocean due to the March 2011 meltdowns at Fukushima Daiichi Nuclear Power Station is returning to Japanese shores via a shorter route than expected, according to a joint research initiative.
The findings were revealed by a team from the University of Tsukuba, the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) and Kanazawa University.
Until now, it was thought that cesium from the Tokyo Electric Power Co. (TEPCO)-operated plant would be circulated around the Pacific by subtropical gyre currents for several decades before returning to Japanese waters. But in 2012, a year after the reactor core meltdowns, tests on seawater samples collected by the team showed increased cesium concentrations in East China Sea waters off Japan. Researchers say that the concentrations observed are too low to impact sea life.
The rate increased, peaking in 2014, and a year later high concentrations were also reported in the Sea of Japan. The team believes the cesium is now flowing around the Pacific Ocean again.
It is thought that seawater sank deeply into the sea after its density increased due to cooling by winter winds, causing the cesium to travel on a western-flowing underwater route.
Michio Aoyama, a visiting professor at the University of Tsukuba, said, “That the cesium would come back in such a short time was unexpected. We’ve found a previously unknown route.”
Senior JAMSTEC research scientist Yuichiro Kumamoto said of the project’s potential benefits, “Because it has visualized ocean circulation, the results could be used in the future for predictions on issues such as climate change.”

Should Fukushima exclusion zone be widened?
FUKUSHIMA investigators were left “worried” after recording radiation levels 100 times normal, leading them to suggest the exclusion zone should be increased.Express UK , By CALLUM HOARE Jul 4, 2019 | “………… when Chernobyl researcher Yevgen visited as part of Amazon Prime’s “Radioactive Detectives” series, he was left shocked.
The narrator revealed in 2017: “Have the Japanese authorities determined the correct exclusion zone?
“The first big surprise is a completely unguarded borderline.
“Yevgen wants to carry out his first measurements here.
“He has to tell Kenzo that the radiation level exceeds the natural radiation 100 times over.

Tokyo monitoring USA-North Korea negotiations, hoping that there will be some real improvement
Japan hopes latest Trump-Kim meeting will help get nuclear, abduction talks moving again, Japan Times , 29 June
KYODO, Japan hopes the third meeting between U.S. President Donald Trump and North Korean leader Kim Jong Un on Sunday will reinvigorate stalled denuclearization talks and help resolve the issue of past abductions of Japanese citizens.
“The meeting could serve as an opportunity for North Korea to come out of its shell,” a senior Japanese Foreign Ministry official said.
Trump and Kim held talks in the Demilitarized Zone dividing the two Koreas and agreed to restart denuclearization talks within weeks following the rupture of their last summit in Hanoi in February.
Tokyo is closely monitoring whether the two countries will move forward negotiations on the denuclearization of North Korea and improve their ties, which could help the U.S. government set up a summit between Prime Minister Shinzo Abe and Kim, as the Japanese leader is hoping for……….https://www.japantimes.co.jp/news/2019/06/30/national/japan-hopes-latest-trump-kim-meeting-will-help-get-nuclear-abduction-talks-moving/#.XRkibT8zbGg
No climate change leadership at G20 summit, and Trump is a disruptive disaster
|
The Guardian view of the Osaka G20 summit: bad as he is, Trump is not the only problem, Editorial, Guardian 268 June 19 The climate crisis underlines the need for effective global economic leadership. The US president makes this harder, but so do China and several others.Ever since the G20 of leading global economies was founded, its summits have mostly been convergent occasions, marked by attempts to find common ground and remembered for nothing more unseemly than a bit of jostling among the heads of government to be on the front row of the group photograph. Japan’s prime minister Shinzō Abe clearly takes this traditional view about the G20 summi twhich he will host in Osaka on Friday and Saturday. “We want to make it a meeting that focuses on where we can agree and cooperate rather than highlighting differences,” he said recently.
But there is a balloon-puncturing problem with Mr Abe’s approach, and it answers to the name of Donald Trump. If there is one issue on which this year’s summit clearly ought to be showing global leadership, it is the climate crisis. The subject is indeed on the Osaka agenda but, in spite of efforts by countries including France, there is no prospect of serious or effective action. That is no surprise from a group of nations which almost tripled the subsidies they gave to coal-fired power plants between 2013 and 2017, with China, India and Japan itself leading the way. But it is Mr Trump’s decision to walk away from climate accords and to back fossil fuels that creates the wider permission for these other terrible derelictions. Mr Trump’s disruptions do not end there. The US president uses these gatherings not to build alliances to solve common problems but to knock his adversaries – and sometimes his supposed allies – off their stride. He is not looking for general agreement, which he thinks is for wimps. He is looking for American advantage over friend and foe. That’s the reason why the summit is already overshadowed by the increasingly serious trade war between the United States and China (Mr Trump will have an all-smiles bilateral with Xi Jinping on Saturday). And it is certainly the reason why Mr Trump has used the run-up to Osaka to have a pop at his hosts, whom he claimed would respond to an attack on the US by watching it “on a Sony television”, attacking India for raising tariffs and then, inventing false figures, berating Germany as a “security freeloader”. Since Mr Trump’s Friday schedule involves one-on-ones with Mr Abe, India’s Narendra Modi and Germany’s Angela Merkel, it seems these mind games are part of a deliberate strategy of disruption. This is not a novel conclusion. Mr Trump used the same approach before his recent visit to Britain, when he praised Boris Johnson and attacked Sadiq Khan and the Duchess of Sussex. If Mr Johnson becomes prime minister and Britain were to back off from supporting European opposition to the White House’s Iran strategy, Mr Trump would count this a job well done. Mr Trump’s bullying is also selective. Among the world leaders whom Mr Trump has not attacked in advance – but with whom he will also be meeting in Osaka bilaterals – are Vladimir Putin of Russia, whose country systematically interfered in the 2016 US election, and Mohammed bin Salman of Saudi Arabia, who has just been accused by the United Nations of orchestrating the murder and dismemberment of the opposition journalist Jamal Khashoggi……… https://www.theguardian.com/commentisfree/2019/jun/27/the-guardian-view-of-the-osaka-g20-summit-bad-as-he-is-trump-is-not-the-only-problem |
