New Japanese nuclear power plant project given go ahead by local authorities

Yamaguchi prefecture in Japan has renewed a landfill license for construction of a new nuclear power plant. The license was halted after the Fukushima disaster. The renewal comes amid heated debate on whether Japan needs new reactors at all.
The license to reclaim land for a new nuclear plant was renewed for the Chugoku Electric Power Co. by the prefectural government on Wednesday, Kyodo news agency reports.
The plant once planned to be constructed in the coastal town of Kaminoseki is positioned “within the country’s energy policy,” the local government said.
Originally, the two-reactor Kaminoseki nuclear complex on an island in the Seto Inland Sea was granted the landfill license in October 2008. The Fukushima crisis brought the construction to a halt at an early landfill work stage, while the license expired in 2012 and was not prolonged, as the former Yamaguchi Governor Shigetaro Yamamoto said the local authorities wanted to “examine the issue appropriately,” but did not make a decision, citing “special circumstances after the nuclear accident.”
Now the landfill license for Kaminoseki nuclear complex has been extended until July 6, 2019, specifically stipulating, though, that the landfill work cannot start until the company presents exact schedule of when the plant facilities are going to be built.
As of now, Chugoku Electric is not ready to elaborate on exact dates when construction will begin, company Vice-President Akira Sakotani said the same day the license was extended.
“We will seriously take to heart the request [by the prefectural government] and carefully consider [our response],” he said.
When the construction of the Kaminoseki nuclear complex began, it was slowed down by protests of the local anti-nuclear energy activists. The activists are expected to go on with their protests now, that the license has been extended.
Anti-nuclear sentiment in Japan have been strong ever since the Fukushima nuclear power plant disaster, but Japan’s huge nuclear energy industry has been stagnating amidst uncertainty for five years now.
Official Tokyo is already pushing for restoring operations of those existing reactors that have successfully met the new post-Fukushima safety requirements.
Just on Wednesday, the No. 3 reactor of Mihama plant in Fukui Prefecture, operated by Kansai Electric Power Co. successfully passed the state safety assessment, becoming yet another nuclear power unit confirmed for safe operations under new regulations.
Big business creeps into agriculture as farmers dwindle
“Fukushima is known for perilla production, and Yajima began cultivating the plant in there in 1999 after learning skills from local farmers. But he pulled the plug on the operation following the triple core meltdown at the Fukushima No. 1 nuclear plant in 2011 during the quake and tsunami disasters in March that year.”
Shigeru Yajima, president of Morishige Bussan Co., takes a close look at perilla his firm is growing in Chichibu, Saitama Prefecture, in July.
With traditional family farms on the wane, corporations are increasingly entering the agriculture sector, taking advantage of an updated law allowing them to lease farmland across the country.
At the end of 2015, more than 2,000 companies were operating in the farm sector, a roughly five-fold increase from before the farmland law was revised in 2009, according to the Agriculture, Forestry and Fisheries Ministry.
Among them is Morishige Bussan Co., a food wholesaler in the city of Saitama that’s growing perilla on a 6-hectare patch of hilly land in Chichibu, Saitama Prefecture.
“We have doubled the patch since last year and are growing perilla all over the field,” Bussan President Shigeru Yajima said in early July.
Perilla plants are grown from seeds raised in vinyl greenhouses; those planted outside two weeks earlier were already 10 cm high.
“We have leased deserted arable land introduced by the Saitama prefectural and Chichibu municipal governments,” Yajima said. “Local people helped us improve the land.”
Oil obtained from perilla seeds is in booming demand as it is considered good for health and beauty, Yajima said.
“Though perilla seeds produced in China and South Korea are available, we stick to homegrown seeds,” he said.
Fukushima is known for perilla production, and Yajima began cultivating the plant in there in 1999 after learning skills from local farmers. But he pulled the plug on the operation following the triple core meltdown at the Fukushima No. 1 nuclear plant in 2011 during the quake and tsunami disasters in March that year.
Chichibu is suited to perilla cultivation because of its wide temperature variations, like Fukushima, said Yajima, who works the fields and processes the crops with five employees. Production of perilla and related business contribute to some 40 percent of Morishige’s annual sales of around ¥100 million.
To meet growing demand for perilla oil, Morishige farms out production of the plant to farmers in Gunma, Nagano and Miyagi prefectures.
Among other firms that have entered the farm sector, Kawaguchi Construction Co., a water supply and road construction company in the town of Minobu, Yamanashi Prefecture, grows Akebono Daizu (Akebono soybeans), a local specialty produced in a cool climate along the Fuji River in the southern part of the prefecture.
“We become busy with public works at the end of each fiscal year,” said Osamu Mochizuki, president of the company. “But as we have lots of time to spare early in each year, I decided (to farm soybeans) to protect jobs for employees.”
The amount of deserted arable land has been growing in Minobu, like other places, in line with the dwindling ranks of Japan’s aged farmers and the lack of successors. The prefectural government offered some 3 hectares of such land to Kawaguchi Construction.
“I decided to grow Akebono Daizu soybeans to help revitalize the local economy, hoping to develop them into a popular brand,” Mochizuki said.
Paste, curd and toasted flour made from dried soybeans are becoming popular. During an annual autumn fair to promote Akebono Daizu, many people visited the town to experience harvesting soybeans.
Of the roughly 2,000 corporations that have entered the agriculture sector, food companies accounted for 23 percent, agricultur and stock-breeding companies 22 percent and construction firms 10 percent.
Meanwhile, schools, medical institutions, social welfare corporations and nonprofit organizations represent a quarter of new institutional entrants into agriculture, according to Shinichi Shogenji, professor at the Graduate School of Bioagricultural Sciences at Nagoya University.
“It is a welcome development for them to use agriculture to support the independence of people with physical or mental disabilities, such as creating job opportunities,” Shogenji said.

New York Just Proved Why Bailing Out Nuclear Power Is a Bad Idea
New York approved a $7.6-$10 billion subsidy to prop up uncompetitive nuclear power plants–twice as much money as it will take for the state to achieve a goal to generate 50% of its electricity with renewables by 2030.
Yesterday, New York became the first state to adopt a policy to subsidize aging, uncompetitive nuclear reactors. The state’s Public Service Commission, which regulates utility companies, passed a Clean Energy Standard that combines a 50% renewable energy standard by 2030 with massive subsidies to prop up uneconomical reactors. (You can download the whole PSC order here.)
Prepare yourself for loud celebrations from the nuclear industry, heaping praise on New York Governor Andrew Cuomo and calling for other states to emulate the Empire State with lucrative incentives to insulate the nuclear industry from competition and to postpone closures of uneconomical reactors.

Japan agrees second reactor life extension since Fukushima
TOKYO Aug 3 (Reuters) – Japan’s nuclear regulator on Wednesday approved an application by Kansai Electric Power Co Inc to extend the life of an ageing reactor beyond 40 years, the second such approval it has granted under new safety requirements imposed since the Fukushima disaster.
The move means Kansai Electric, Japan’s most nuclear-reliant utility before Fukushima led to the almost complete shutdown of Japan’s atomic industry, can keep No. 3 reactor at its Mihama plant operating until it is 60 years old.
The regulator granted the first such approval in June to Kansai Electric’s ageing reactors No.1 and 2 at its Takahama plant.
The Mihama No.3 reactor, which will turn 40 years old in December, has been shutdown since 2011 and a restart will not happen immediately as Kansai Electric needs to carry out safety upgrades at a cost of about 165 billion yen ($1.63 billion).
The upgrades involve fire proofing cabling and other measures and are planned to be completed in March 2020, a company spokesman said.
Opinion polls consistently show opposition to nuclear power following Fukushima. Critics say regulators have failed to take into account lessons learned after a massive earthquake and tsunami caused meltdowns at the Fukushima Daiichi plant.
Nuclear disaster evacuation plans worry many local authorities
Workers clean up a bus that transported evacuees in a nuclear disaster evacuation drill in Shizuoka in February.
Nearly half of local governments polled are concerned about the recommendation that residents living within 5 to 30 kilometers of a nuclear power plant should “evacuate” by staying indoors if a serious accident occurs, an Asahi Shimbun survey found.
The survey also showed that a quarter of local governments want a review of the central government’s evacuation guidelines, which were set in October 2012 following the Fukushima nuclear disaster the previous year.
It was taken to find how local governments hosting a nuclear facility or located in the vicinity of a nuclear plant view the guidelines in light of the recent series of earthquakes in Kumamoto Prefecture.
In the quakes that began in mid-April, a large number of homes, as well as roads and other structures, were damaged. Continuing aftershocks added to difficulties in victims’ abilities to evacuate quickly.
The nuclear disaster evacuation guidelines were compiled on the assumption of a serious accident occurring at a nuclear complex, but do not take into account the destruction of evacuation routes, bridges and other buildings in the surrounding area, caused by a powerful earthquake, for example.
Shiga Prefecture, which called for a review of the guidelines in May, said: “Indoor evacuation would be unrealistic if a nuclear accident were coupled with an earthquake. Evacuation to the area beyond 30 km should be considered.”
Under the current setup, people living within a 5-km radius are ordered to evacuate immediately.
Those within a radius of 5 to 30 km are advised in principle to stay indoors initially and evacuate in stages, depending on the amount of radiation released into their neighborhoods.
“Indoor evacuation” for such a zone is aimed at allowing the smooth evacuation of people in the 5-km zone first to avoid an expected gridlock.
But many local governments are wary of the central government’s recommendations, citing the possibility of a complex disaster involving more than just a nuclear accident, according to the survey.
The survey, conducted in mid-June and mid-July, covered 21 prefectural governments and 135 municipalities that fall within the 5-30 km radius. All the local governments responded but one, the Fukui prefectural government.
Of the total of 155, The Asahi Shimbun analyzed the responses of 151, as the remaining four municipalities replied that they will evacuate immediately. Most of these municipalities’ jurisdictions are also situated within the 5 km radius.
The survey showed that 71 local governments, including Niigata and Ibaraki prefectures, expressed concerns about the guidelines, while 22 replied that they are not.
Asked to choose one or more reasons for their anxiety, 56 cited the response to a situation where a large number of structures are destroyed.
As for the need to review the guidelines, 37 respondents, including Nagasaki and Shizuoka prefectures, agreed while 13 did not. Sixty-four said they don’t know.
According to the survey, 12 local governments replied that they are well prepared with regard to the infrastructure that enables smooth evacuation, whereas 69 cited problems with that issue.
How to evacuate in a nuclear accident that could be triggered by a devastating earthquake or another disaster that destroys homes and infrastructure has emerged as a pressing issue since the Kumamoto temblors.
Kagoshima’s new governor, Satoshi Mitazono, was elected in July on his campaign pledge to review the existing evacuation plan in connection with a hypothetical accident at the Sendai nuclear power plant.
The nuclear power station in Satsuma-Sendai in the prefecture is the only plant online in the nation and is situated relatively close to an active fault that is believed to have slipped in the Kumamoto quakes.
Despite growing concerns voiced by local governments, the Nuclear Regulation Authority’s secretariat, which compiled the guidelines, said in an interview with The Asahi Shimbun that it will not consider a review.
“Indoor evacuation will not be for a prolonged period,” said an official. “Gyms and other public facilities would be available for residents even if their homes were destroyed.”
The official also said local governments can improve their evacuation plans based on their understanding of local conditions.
Tepco’s Profit Plummets Amid Declining Sales and New Competition
Operating profit falls by 37 percent in the first quarter
More than 750,000 Tepco customers have switched providers
Tokyo Electric Power Co. Holdings Inc., operator of the wrecked Fukushima Dai-Ichi nuclear plant, said first-quarter operating profit plummeted 37 percent as sales declined amid faltering demand and new entrants into Japan’s power market.
Tepco, as Japan’s biggest utility is known, posted operating profit of 143.6 billion yen ($1.37 billion) for the three months ended June 30, down from 228.3 billion yen a year ago, the company said in a statement Thursday.
Revenue fell about 18 percent to 1.26 trillion yen as the company’s electricity sales volume dropped and rates were automatically lowered by the nation’s price adjustment system. The system adjusts monthly electricity rates for each utility based on a three-month average of import prices for LNG, crude oil and coal.
Japan’s regional utilities are getting squeezed by new entrants after the country liberalized its retail power market in April, allowing consumers to choose their electricity providers for the first time. Tokyo Electric hopes to boost its profits by expanding its domestic gas sales when the market fully opens up next year, increasing its foreign investments and restarting its operable nuclear reactors.

Reuse of radioactive soil could cut costs by 1.5 trillion yen: ministry estimate
Behind the Environment Ministry’s controversial decision to allow reuse of highly radioactive soil emanating from the Fukushima nuclear disaster in public works projects was an estimate that the reuse could cut the costs of reducing radiation levels of such soil by over 1.5 trillion yen, it has been learned.
The estimate in question was presented during a closed-door meeting of the ministry in January and stated that reuse of radioactive soil generated from Fukushima decontamination work could cut the cost for purifying such soil from 2.9127 trillion yen in case the levels of radioactive cesium are reduced to 100 becquerels per kilogram to 1.345 trillion yen in case the cesium levels are cut down to 8,000 becquerels per kilogram. The estimate calls the latter option “reasonable from economic and social points of view.”
The Environment Ministry decided in June to allow reuse of soil with radioactive cesium of no more than 8,000 becquerels per kilogram in mounds under road pavements and other public works projects. The decision sparked criticism that it runs counter to the safety standards of 100 becquerels or less for recycling metals generated from the decommissioning of nuclear reactors under the Act on the Regulation of Nuclear Source Material, Nuclear Fuel Material and Reactors. The ministry has insisted that the radiation levels of tainted soil used in road mounds can be held down from 8,000 becquerels to around 100 becquerels by covering those mounds with concrete among other measures.
A ministry working group on safety evaluation of radiation effects held closed-door meetings over the issue on six occasions between January and May this year. In June, the Mainichi Shimbun reported that an estimate presented to one of those meetings stated, “For example, it will take 170 years for radiation levels to reduce to 100 becquerels if tainted soil of 5,000 becquerels is put to reuse,” sparking controversy. In response, the ministry on Aug. 1 released the minutes of the closed-door meetings and other documents on its website.
At the second meeting of the working group on Jan. 27, the copies of a document titled “About reasonable radioactivity concentrations of recycled materials” were handed out to attendants. The document, which was drawn up by the Japan Atomic Energy Agency, includes an estimate that the cost for reducing the radiation levels of tainted soil to 100 becquerels for recycling would reach 2.9127 trillion yen, with a volume reduction rate of 40 percent, adding that 40 percent of contaminated soil could not be put to reuse. Meanwhile, the estimate says it would cost 2.1185 trillion yen to drop the radiation levels of tainted soil to 3,000 becquerels, with a volume reduction rate of 0.5 percent, while it would cost 1.345 trillion yen to decrease the radiation levels of soil to 8,000 becquerels, with a volume reduction rate of 0.2 percent. The latter option could make 99.8 percent of tainted soil available for reuse, the estimate says.
“Considering economic and social factors, it is appropriate to set the radioactivity concentration of recycled materials at several thousand becquerels,” the document stated. A note of caution in the document states, “Apart from this, it is necessary to project the cost for final disposal (of tainted soil).”
A ministry official in charge of the issue told the Mainichi Shimbun, “The document was produced in response to a request by a member of the working group. As the document states, it is difficult to (set the standards for reusing tainted soil) at 100 becquerels from a realistic point of view.”

License renewed for new nuclear plant project in western Japan
Planned construction site for Kaminoseki nuclear plant
File photo taken in October 2012 shows the planned construction site for a Chugoku Electric Power Co.’s nuclear plant in the western Japan town of Kaminoseki. Local opposition and the 2011 Fukushima nuclear disaster have prevented development of the construction project.
YAMAGUCHI, Japan (Kyodo) — The Yamaguchi prefectural government on Wednesday renewed a license for Chugoku Electric Power Co. to reclaim land for a new nuclear power plant in the western Japan prefecture, surprising and angering local residents opposed to the project.
Whether to extend the expired license for landfill work in the coastal town of Kaminoseki to build the Kaminoseki Nuclear Power Station had been a pending issue after the 2011 Fukushima nuclear crisis led to the suspension of the work. But the local government decided to grant permission, saying that the plant is positioned “within the country’s energy policy.”
The utility is unlikely to quickly restart the work due to local opposition, however. The local government’s license renewal is also conditional: It said landfill work should not start until prospects of building plant facilities become clear.
But the latest development could open up substantial discussions on whether new reactors should be built in Japan, which the central government has largely avoided so far in consideration of antinuclear sentiment that has prevailed after the Fukushima nuclear power plant disaster.
Meanwhile, the government has already been pushing for the resumption of existing reactors that have met post-Fukushima safety requirements. On Wednesday, the No. 3 reactor at Kansai Electric Power Co.’s Mihama plant in Fukui Prefecture became the latest unit to have effectively cleared the state safety assessment.
Chugoku Electric was initially granted the landfill license in October 2008 for the two-reactor Kaminoseki nuclear complex on an island in the Seto Inland Sea.
The company began landfill work a year later, but progress was slow amid local protests and was suspended after the Fukushima crisis was triggered by a huge earthquake and tsunami that hit northeastern Japan in March 2011.
Just before the license was set to expire in October 2012, the utility applied for a three-year extension to the prefectural government. “We have not changed our idea that we need the Kaminoseki plant. We want to keep the license,” a utility official said at the time.
Then Yamaguchi Gov. Shigetaro Yamamoto said the local government will “examine the issue appropriately” but did not make a decision, citing “special circumstances after the nuclear accident.”
But on Wednesday, the prefectural government reversed course and permitted the extension of the license, though saying that landfill work should not begin until the utility has clear prospects of building plant facilities.
Chugoku Electric Vice President Akira Sakotani said the same day that there is currently no specific date set for building the facilities.
“We will seriously take to heart the request (by the prefectural government) and carefully consider (our response),” he said.
The license will be effective until July 6, 2019.
The decision of the prefectural government drew mixed responses from local residents.
“I can’t believe the permission was given,” said Toshiyasu Shimizu, 61, who heads a group of residents on an island several kilometers from the construction site.
But Naonori Koizumi, a 58-year-old member of a group supporting the construction project, said, “I don’t think work will immediately resume, but the town is depopulating and graying. I hope nuclear power will make this town richer.”

Tepco’s hazmat suit guideline decreases burden on workers during summer heat
Tokyo Electric Power Company Holdings Inc., operator of the crippled Fukushima No. 1 power plant, has been revising guidelines for when workers need to wear full masks with hazmat suits or less-bulky outfits to improve their working conditions during the scorching summer.
While a full-body outfit limits radiation exposure, hazmat suits and full masks have been a heavy burden for workers because they restrict movement and make it difficult to breathe, prompting Tepco to revise the guidelines on their usage.
In March, Tepco changed the guidelines, dividing the premises into three areas.
In the area where radiation levels remain high, including inside reactor buildings 1, 2 and 3, workers will need to wear a full mask and disposable hazmat suit with a raincoat-like outer layer.
Workers meanwhile will need to wear full or half masks with hazmat suits in areas where radiation levels are lower, such as near tanks filled with radiation-tainted water. In the remaining area, the majority of which has low levels of radiation, workers only need to use disposable masks and their usual work outfits, Tepco said.
According to the utility, out of about 5,000 to 6,000 workers on the premises, about 47 percent were required to wear a full mask in June, down from about 66 percent in January, before the guidelines were changed.
Those who are required to wear a half mask increased to 48 percent from 28 percent in the same period, it said.
Before the guidelines were revised, about 8,000 disposable hazmat suits were used per day, but the number declined to about 4,000.
Even as hazmat suit requirements have halved, radiation exposure cases have remained unchanged at an average of two a day, Tepco said, adding that the risk of radiation exposure has not increased.
Tepco said it will offer summer outfits at the beginning of this month to lessen the chance of workers succumbing to heatstroke.
In July, the health ministry opened a health care office at J-Village near the Fukushima No. 1 power plant so that its workers can seek free health consultations from doctors who are versed in radiation exposure.
“During the summer period, the health of workers tends to worsen due to heatstrokes as well as other illnesses, so we need to step up measures to resolve the situation,” said a heath ministry official.
Small Progress of Landside Impermeable Wall freezing
The purpose of the Landside Impermeable Wall construction lies not in freezing soil to form an underground wall but in keeping groundwater from flowing into the reactor/turbine buildings and preventing new contaminated water being generated.
By closing less than 95 percent of the mountain side of the Landside Impermeable Wall in Phase 2 of the first stage, it is expected that the amount of groundwater flowing into the areas around the reactor/turbine buildings will be reduced. This will help keep groundwater from being contaminated during the first stage.
Throughout the first stage, how freezing of the Landside Impermeable Wall has progressed will be checked by monitoring the difference in groundwater levels inside and outside of the wall and the amount of groundwater pumped up by the subdrain and groundwater drain systems and the wellpoint system.

Progress of supplementary work
Progress of supplementary work (1BLK)
Over-time changes of the soil temperatures in the north side area of Unit 1 where the supplementary work is in progress The soil temperatures temporarily increased because of water which was used to bore through the ground during the supplementary work, but it has gradually decreased. Since the soil temperature around the thermometer pipe of 120-1S has not dropped sufficiently, however, the second round of injection is currently under way. TEPCO Holdings will continue to monitor the temperature changes.
Progress of supplementary work (9BLK)
As seen in the soil temperatures in the 1BLK area, that in the 9BLK area temporarily increased because of water which was used to bore through the ground during the supplementary work. The soil temperature around the thermometerpipe of 30-9S0 has dropped to around 0 degrees Celsius, and TEPCO Holdings will continuously monitor it. In the area around the thermometer pipe of 70-9S, the second round of injection is progressing.
Progress of supplementary work (12BLK)
Over-time changes of the soil temperatures in the east side area of Unit 2 (12BLK) where the supplementary work is in progress The soil temperatures have gradually decreased. Monitoring of the temperatures will continue.
Progress of supplementary work (13BLK)
Over-time changes of the soil temperatures in the east side area of Unit 2 (13BLK) where the supplementary work is in progress Since the soil temperature around the thermometer pipe of 30-13S has slowly decreased, the second round of injection is planned. Although the decrease of the soil temperatures around the thermometer pipes of 50-13S and 90-13S have been gradual but steady, monitoring of the temperatures is still under way.
Purpose of supplementary work
To help further freeze soil in places where the soil temperatures have slowly dropped due to fast flowing groundwater, the speed at which the groundwater runs has to be reduced by making the permeability of the soil as low as that of soil in the vicinity of the places.
The purpose of the supplementary work lines not in constructing different walls from the landside impermeable wall but in changing locally highly permeable soil areas into areas with low permeabilities observed in the soil of the surrounding area.

Anti-terror facility at nuclear plant confirmed
Japan’s nuclear regulator says plans for terrorism-response facilities at the Takahama nuclear plant are the first in Japan to meet its requirements.
New government regulations introduced after the 2011 Fukushima Daiichi accident require nuclear plant operators to build standby control rooms at least 100 meters away from each of their reactors.
The special facilities allow employees to retain control of a plant’s reactors even if main control rooms are destroyed by terrorists or in a plane crash.
Officials at the Nuclear Regulation Authority confirmed that the plans for standby control rooms for the No. 3 and No.4 reactors at the plant are in line with requirements. They will soon issue formal approval for construction.
The decision came at a closed-door session to maintain secrecy of the rooms’ design and location.
The Takahama plant on the Japan Sea coast became the first of 7 nuclear plants in Japan to submit applications for approval.
The plant’s operator, Kansai Electric Power Company, is now required to set up the facility for the No.3 reactor by August 2020 and for the No.4 reactor by the following October.
Some are criticizing the decision to restart reactors yet to be equipped with the standby facilities.
The 2 reactors at Takahama went back online earlier this year. But they were halted after a court ordered their suspension in March.
One More Worker Drops Dead At Fukushima Daiichi
Another worker died on July 30, 2016 at Fukushima Daiichi. Tepco’s report indicates that he was found dead around 10:39am.
The weather recently has been warm but not extremely hot. Some of the early cases of workers dropping dead or falling ill at the plant were considered heat related. After this some heat related counter measures were put in place. Other cases were either never explained or vaguely claimed to be due to health problems.

Hiroshima museum gets hibakusha’s rare copy of A-bomb tanka book written behind censors’ backs
A tanka collection by late hibakusha poet Shinoe Shoda, recently found in a private home, has been donated to the city of Hiroshima.
HIROSHIMA – A copy of an anthology of traditional tanka by Shinoe Shoda written to depict the horrors of the atomic bombing of Hiroshima and secretly published during the Allied Occupation has been discovered at a temple in Hiroshima Prefecture.
The anthology, titled “Sange,” a Buddhist term meaning death, was donated to the Hiroshima Peace Memorial Museum in the city on Tuesday.
The only other copy was thought to be one found earlier at the house of a relative of the late poet.
The donated copy is “a precious and rare material,” said an official at the Hiroshima Municipal Government’s peace promotion division.
Shoda experienced the atomic bombing while at home, only about 1.7 km from ground zero.
The anthology includes about 100 tanka that give graphic descriptions of what she experienced or heard from other hibakusha.
A translation of one tanka reads:
“The heavy bones / must be the teacher / and alongside / small skulls / are gathered.”
In 1947, when the anthology was published, Japan was under U.S.-led Occupation and severe restrictions had been imposed on publications and reporting related to the A-bombings of Hiroshima and Nagasaki, according to the municipal government.
To evade Occupation censors, Shoda picked Hiroshima Prison as the place to print about 150 copies of the anthology. The copies were handed out only to people close to her.
About 10 years ago, Tomoaki Shoja, the 60-year-old chief priest of Sentokuji Temple in the town of Kitahiroshima, discovered a copy of “Sange” when he was organizing his late priest’s belongings.
The original owner is believed to have given it to Shoja’s family because a son of Shoda was evacuated to the temple in the closing days of the war.
The museum is considering putting the anthology on display.
“Not many people know Shoda,” said Shoja. “She could become better known if more people have the chance to see the anthology.”
America to upgrade its B61 nuclear missile
New deterrence: US plans to upgrade its nuclear bomb Rt.com 2 Aug, 2016 The National Nuclear Security Administration has given the go-ahead for work on upgrading the B61 airborne nuclear bomb, as the Pentagon is eager to embark on a multi-billion-dollar scheme to improve the US nuclear arsenal.
The decision taken by the National Nuclear Security Administration (NNSA) authorized the program to enter a post-engineering phase, which comes after four years of work. This now means that the first upgraded bombs are set to roll out by 2020.
The B61 has been the principal US airborne nuclear bomb since 1968, when the first version was commissioned. With some of the modifications being canceled over the years and others withdrawn from use, only models 3,4,7,11 and 12 are currently in active service……
The Kremlin has been cautious about the announcement that the US intends to modernize the B61 nuclear bomb.
“The experts need to give their opinion about this,” said Dmitry Peskov, President Vladimir Putin’s press secretary.
Meanwhile Senator Viktor Ozerov told RIA that Russia’s nuclear scientists would be assessing the US plans and would take steps to tackle the proposed threat if it is deemed necessary. “No doubt, our nuclear weapons specialists will carefully study the level of threat and will take measures to minimize it, if needed,” Ozerov said.
However, Rob van Riet, the coordinator for disarmament program at the World Future Council foundation, told Sputnik that the decision is harmful to nuclear security and could lead to the weapons being used by accident, while it also “sends the wrong signal.”
“The decision to extend the life span of [or] modernize the system is an unnecessary one that comes at a sizeable price tag and does the opposite of advancing nuclear security and disarmament. These weapons are a remnant of the Cold War,” van Riet said.
The decision taken by the NNSA to prolong the life of the B61-12 also comes as the US Air Force announced that it is planning to move ahead with proposals to replace its current intercontinental ballistic missile and nuclear cruise missile with new programs. …….https://www.rt.com/usa/354364-bomb-nuclear-upgrade-pentagon/
