Telegraph 11th May 2018 , Closing down North Korea’s nuclear test site at Punggye-ri is going to be
more complicated and fraught with risk than has previously been suggested, with analysts suggesting that acting in haste for short-term political gain might lead to an environmental crisis.
One suggestion is to use explosives to seal the entrances to the three tunnels that have been drilled into the
mountain, although the concern is that further detonations at the already weakened site could lead to a collapse of internal spaces and the release of massive amounts of radioactivity into the atmosphere.
Given the danger, the alternative is to bury the entire site in a mixture of lime and sand.
The Monju fast-breeder reactor experiment yielded few sufficient results despite an investment of at least ¥1.13 trillion ($10.3 billion) worth of taxpayers money since 1994, state auditors confirmed on Friday.
The trouble-plagued prototype, which only ran for 250 days, was designed to play a key role in Japan’s quest to set up a nuclear fuel recycling program, but the project only achieved 16 percent of the intended results, the Board of Audit said.
The government finally decided to scrap Monju in December 2016 at an estimated additional cost of ¥375 billion. But the audit board noted that the 30-year decommissioning plan could cost even more.
The reactor, which started operations in 1994, was designed to produce more plutonium than it consumes while generating electricity, experienced several problems over its more than two-decade run, including a sodium coolant leak and attempted cover-up, and equipment inspection failures.
“Flawed maintenance led to the decommissioning,” the auditors concluded in their report.
But the report also spotlights the absence of a systematic evaluation system for the project. During the entire experiment, the auditors expressed their opinions on Monju’s research and development costs only once — in 2011.
Monju was only up and running for 250 days in total after repeatedly failing to complete test items, according to the report.
As for the decommissioning costs, the report said they might expand because the current estimate does not include personnel costs and taxes. It also noted that the cost of removing the radioactive sodium coolant could change.
Offshore Wind Journal 10th May 2018 , Taiwan’s Government is making good on longstanding plans to close nuclear power plants and invest heavily in offshore wind energy. Late April 2018
saw the authorities in Taiwan announce the results of the first large-scale
auction for offshore wind in the country, a process that will eventually
see around 3.8 GW of capacity being built there.
This demonstrates theTaiwanese Government’s determination to follow-through and execute plans
announced earlier for the sector. Taiwanese President Tsai Ing-wen has
proposed to end the country’s dependence on nuclear power by 2025 while
sourcing 20% of Taiwan’s electricity from renewable sources – that is,
five times the level in 2015. That plan depends heavily on offshore wind,
for which the Taiwan Strait is seen as particularly well-suited.
Data provided by law firm Jones Day showed that in 2016, electricity generated
from renewable energy accounted for 4.8% of the aggregate produced
electricity and 9.4% of the aggregate installed capacity in Taiwan, so the
government’s strategy is certainly an ambitious one. In due course the
Taiwanese Government would like to have an energy mix of 50% natural gas,
30% coal and 20% renewable energy. http://www.owjonline.com/news/view,taiwan-makes-good-on-plan-to-replace-nuclear-power-with-wind_51748.htm
Oi nuclear power plant’s No. 4 reactor (far left) in Fukui Prefecture is seen on Wednesday before being restarted by Kansai Electric Power Co.
May 10, 2018
OI, FUKUI PREF. – Kansai Electric Power Co.’s No. 4 reactor at its Oi nuclear plant in Fukui Prefecture inched closer toward running at full capacity Thursday, four years and eight months after operations were suspended.
The reactor has reached criticality, its nuclear fission chain reaction having reached a self-sustaining state, and is set to begin power generation and transmission Friday. It is projected to reach full capacity early next week.
The reactor, which was halted in September 2013 for regular checkups, is the eighth to have been reactivated under the country’s new safety standards for nuclear plants. The new standards were introduced in the wake of the March 2011 triple meltdown at Tokyo Electric Power Company Holdings Inc.’s tsunami-stricken Fukushima No. 1 nuclear plant.
Kansai Electric plans to put the No. 4 reactor into commercial mode in early June and cut its electricity prices this summer.
Commercial operations of the No. 3 and No. 4 reactors at the Oi plant are projected to help reduce the firm’s fuel costs by about ¥120 billion a year. The No. 3 unit was brought back online in March this year and entered commercial mode in April.
The utility lowered its electricity rates for households by 3.15 percent on average in August 2017, after it resumed commercial operations of the No. 3 and No. 4 reactors at its Takahama plant in Fukui Prefecture.
As each of the two Oi reactors has a capacity of 1.18 million kilowatts — larger than the 870,000 kilowatt capacity of each of the Takahama reactors — the forthcoming rate cut may be more significant than the previous one and could bring the company’s electricity prices down to levels from before the Fukushima nuclear accident, industry observers said.
Kansai Electric owns 11 reactors — four each at the Oi and Takahama plants, and three at the Mihama plant, also in Fukui Prefecture.
Besides the four currently in operation, the Mihama No. 1 and No. 2 units and the Oi No. 1 and No. 2 units are set to be decommissioned. The Mihama No. 3 unit and the Takahama No. 1 and No. 2 units are undergoing work to allow them to continue to operate after reaching 40 years of service.
With the Oi and Takahama plants located as little as 13.5 kilometers from each other, the plant operator has been urged to draw up measures that should be taken in case accidents occur at the same time at the two facilities.
This summer the government plans to carry out a comprehensive anti-disaster drill assuming simultaneous accidents.
Trump’s decision to reimpose sanctions on Iran clearly violates the multilateral Iran nuclear deal, known officially as the Joint Comprehensive Plan of Action (JCPOA). While the move is unsurprising—given Trump’s failure to recognize the nonproliferation value of the deal and frequent threats to walk away—it is dangerous and irresponsible, and it risks manufacturing a nuclear crisis that the international community cannot afford.
There was no legitimate reason for Trump to reimpose sanctions. For the past two years, the nuclear deal has verifiably restricted Iran’s nuclear program and subjected it to intrusive monitoring and verification. Even critics of the deal, such as Secretary of State Mike Pompeo, have admitted that there is no evidence that Iran is in violation of the agreement.
Trump’s main criticism—that the deal paves the way to an Iranian nuclear weapon in 10 years—is based on a flawed analysis that discounts the value that the permanent monitoring mechanisms and prohibitions put in place by the deal possess. They are a bulwark against nuclear weapons development.
By violating the deal, Trump has only isolated the United States and undermined Washington’s credibility. His “plan B” —to negotiate a “better deal” with Iran— is completely unrealistic. After this clear demonstration that the United States cannot be counted on to implement an agreement in good faith, Trump will hard pressed to gain any support for sanctions, let alone new talks. As a result, Trump is inciting a proliferation crisis, rather than working with allies to develop a long-term diplomatic strategy that would build on the agreement in the years ahead and address Iran’s malign activities outside of the accord.
Despite Trump’s reckless decision to reimpose sanctions, it would be premature to declare the nuclear deal dead. The JCPOA is a multilateral agreement endorsed by the UN Security Council and Washington’s P5+1 partners—China, France, Germany, Russia, and the United Kingdom—which have pledged to implement the deal, irrespective of US actions. And these states and the European Union have powerful tools at their disposal to block the secondary effects of US sanctions.
It will be critical that these states move quickly to insulate legitimate business from US sanctions, demonstrating to Iran that there is still an incentive—trade with Europe and other developed economies—to continue abiding by the nuclear commitments made under the accord. Failure to ensure that Iran has international trading opportunities will make it more likely that Tehran will respond to Trump’s violation by breaching the nuclear limits. While Iran is unlikely to dash for a bomb, Iranian officials have left the door open to restart uranium enrichment to 20 percent uranium 235, a level of fissionable material currently prohibited by the deal. If Iran choses this path it would destabilize the region and increase the risks of conflict.
Trump’s decision has nonproliferation consequences beyond Iran. Trump is about to sit down at an important summit with North Korean leader Kim Jong-un to discuss denuclearization of the Korean peninsula. Violating the Iran deal undermines US credibility in those negotiations and sends a message to Kim Jong-un that even if an agreement is reached and North Korea abides by its terms, there’s no guarantee that Washington will fulfill its commitments. This is a dangerous precedent to set and risks this historic opportunity to de-escalate tensions with North Korea.
Singapore will host U.S.-North Korea summit, nuclear issue to dominateSteve Holland, Matt Spetalnick WASHINGTON (Reuters), 11 May 18 Leaders of the United States and North Korea will meet for the first time when President Donald Trump and Kim Jong Un hold a summit on June 12 in Singapore where the U.S. side will try to persuade Pyongyang to give up its nuclear weapons.
…….. “The highly anticipated meeting between Kim Jong Un and myself will take place in Singapore on June 12th. We will both try to make it a very special moment for World Peace!” Trump wrote on Twitter…….
Trump is embarking on this high-stakes meeting with Kim after sending shockwaves through the world on Tuesday when he announced that the United States was pulling out of a 2015 accord imposing international oversight of Iran’s nuclear program.
The move raised questions over whether North Korea might now be less inclined to negotiate its own nuclear deal with Washington.
Trump and Japanese Prime Minister Shinzo Abe spoke by telephone on Wednesday and the White House said the two leaders “affirmed the shared goal of North Korea abandoning its illicit weapons of mass destruction and ballistic missile programs” and remained committed to cooperating with South Korea.
Japan worries that it could be the target of any first-use of nuclear weapons by Pyongyang.
……… Kim recently promised to suspend missile tests and shut a nuclear bomb test site.
North Korea is still technically at war with the United States and its ally South Korea because the 1950-53 Korean War ended in a truce, not a treaty.
The choice of Singapore will put the summit on friendly turf for Trump, as the island nation is a strong U.S. ally and the U.S. Navy frequently visits its port.
The wealthy financial and shipping hub is seen as a gateway between Asia and the West and has been called the “Switzerland of Asia,” in contrast to North Korea’s isolated economy that its leaders now want to modernize.
Or, he’s making the rest of the world think he is by arranging a performance for the satellites that pass overhead.
Satellite images taken since last month’s inter-Korean summit show a steady reduction in the number of buildings around North Korea’s known nuclear test site, built under Mount Mantap in the Punggye-ri area in the north of the country.
“At the very least, this a welcome PR move,” said Jeffrey Lewis, head of the East Asia program at the James Martin Centre for Nonproliferation Studies in Monterey, California.
“Over the past two weeks, five or six buildings have inexplicably come down,” Lewis said, citing commercial satellite images from the San Francisco-based firm Planet Labs that have a resolution comparable to Google maps. “Something is clearly happening there.”
As part of the extraordinary rapprochement now going on, North Korea has vowed to dismantle the test site, where all six of its nuclear detonations have taken place, this month. But as with so many things about North Korea, it’s difficult to tell how much of this is wheat and how much is chaff.
Kim made the pledge during a historic summit with South Korean President Moon Jae-in, which laid the groundwork for a meeting between Kim and President Donald Trump that will likely take place in the next month or so.
Kim said he would invite security experts and journalists to the North to observe the closure of the site, the South’s presidential Blue House said.
All six of North Korea’s nuclear tests have taken place deep under the mountain at Punggye-ri, with five of them occurring in the tunnel complex accessed through an entrance known as the north portal. There are two other entrances to the site, the west and south portals.
The last test, in September last year, was so huge that some experts wondered if Mount Mantap was suffering from “tired mountain syndrome” and had become unusable. But numerous nuclear experts have cast doubt on that theory, noting that even if the tunnels leading to the north portal were unusable, the other two entrances could still be operational.
Tunnelling and activity at the west portal had been visible as recently as April 20, a week before the inter-Korean summit, according to an analysis for 38 North, a website devoted to North Korea.
There are clusters of buildings at the portals, including administration buildings and a command center, as well as smaller buildings.
The big, main buildings are still there but the smaller, more peripheral ones at the north and south portals, the entrances to the main tunnels, have come down, Lewis said.
This could be part of the preparations for inviting journalists and experts to watch the closure of the site, which, Lewis said, could be as simple – and as reversible – as blocking the portals.
“Shutting down the test site is something they can easily do. It’s just tunnels so they can seal the entrances – but they can also unseal them,” he said.
“And the tunnels are always going to be there,” he added, unless North Korea blows up the whole site.
Still, analysts wanting to be optimistic about the diplomatic process say that declaring the site finished and taking some steps towards closing it would support their theory that Kim is making an effort, just like this week’s release of three Americans who had been held in North Korea.
But sceptics say that closing a test site that might well be spent is just cosmetic.
A group of Chinese scientists last month said they believe the test site had collapsed after September’s huge test, which caused an earthquake so big that satellites caught images of the mountain above the site actually moving.
North Korea claimed to have detonated a hydrogen bomb, which would be exponentially more powerful than the atomic devices previously tested, and experts said the size of the earthquake suggested that it had indeed been a hydrogen, or thermonuclear, explosion.
Adding to theory that the site has outlived its utility is new research from scientists from the Earth Observatory of Singapore at Nanyang Technical University, who claim to have found evidence that the damage at Mount Mantap was more substantial than other research shows.
In their study, which will be published in the journal Science on Thursday, they argued that by using satellite radar imagery to supplement ground-based seismological readings they were able to gain a more accurate picture of the September 3 test.
Sylvain Barbot, a researcher with the Earth Observatory of Singapore, wrote in an e-mail that the nuclear test last year was so large that “we could ‘feel’ it from space.”
The amount of shaking that accompanied the explosion was so severe that traditional radar measurements were inaccurate, Barbot said, and his team had to use unusual techniques to compensate for significant changes in the landscape.
By using these techniques, the researchers were able to estimate a depth for the nuclear detonation: Around 450 metres, beneath the summit of Mount Mantap. Researchers then combined this information with seismological readings to come up with an estimated yield for the weapon of between 120 kilotons to 304 kilotons.
Much of this range would be far higher than officials from the United States and South Korea estimate.
The researchers also found evidence that a significant part of Mount Mantap had collapsed after the explosion, supporting the Chinese study. A “very large” part of the facility had collapsed, Barbot said, “not merely a tunnel or two.”
An underground North Korean nuclear test in September last year exploded with 10 times the energy of the atomic bomb that exploded over Nagasaki in 1945.
It also caused the overlying mountain peak to sink by half a metre and shift about 3.5 metres south.
Key points:
North Korea detonated a nuclear bomb under Mt Mantap on September 3, 2017
Using satellite measurements and seismic data, geophysicists calculated the strength of the test and its location — the first time satellite radar has been used this way
The blast was big enough to cause an earthquake and deform the mountain above
These are conclusions drawn by geophysicists, who used satellite radar and instruments that pick up waves travelling through the earth, to calculate the explosion’s depth and strength.
In the journal Science today, they also report signs that a subterranean tunnel system at the test site collapsed 8.5 minutes after the bomb detonated.
In the past, satellite technology — called synthetic radar aperture imagery — has mapped how the ground stretches and warps after earthquakes.
But this is the first time it has been used to examine a nuclear bomb test site, according to Teng Wang, study co-author and a geophysicist at Singapore’s Nanyang Technological University.
Since the United Nations General Assembly adopted the Comprehensive Nuclear-Test-Ban Treaty in 1996, nine nuclear tests have taken place.
Six of these were by North Korea, five of which were at its Mt Mantap facility in the country’s north.
The bombs were detonated in chambers tunnelled into the mountain itself — a granite peak that extends upwards just over 2,200 metres.
But this means the details of the tests, such as the energy produced by the bombs, have been largely unknown outside North Korea — until now.
Eye in the sky, ear to the ground
Dr Wang and his colleagues suspected they could deduce the strength and precise location of the bomb test on September 3 last year, which triggered a magnitude-6.3 earthquake.
Clandestine nuclear activities are tracked by a global monitoring system of sensors that pick up the faint shivers and shudders generated by distant underground blasts and earthquakes.
But while these instruments are capable of picking up the wave signature of a bomb blast thousands of kilometres away, more information is needed to pinpoint exactly where an explosion has taken place.
So in the weeks after the September North Korean bomb test, Dr Wang and his colleagues received images of the Mt Mantap terrain before and after the test, snapped by the German TerraSAR-X satellite.
To map the bumps and dips on the Earth’s entire surface, TerraSAR-X pings radar towards the ground and measures how long it before the signal is bounced back up again.
“As long as the ground is deformed, we can measure it from space using synthetic radar aperture,” Dr Wang said.
Combined with a bit of nifty mathematical modelling — the first time anyone’s modelled an underground nuclear test with radar data — he and his colleagues got a fix on the exact location of the detonation site.
This is a highlight of the work, said Hrvoje Tkalcic, a geophysicist at the Australian National University, who was not involved in the study.
“What’s always difficult is pinpointing an exact location [of a bomb test],” Professor Tkalcic said.
Dr Wang and his team calculated that the top of the mountain subsided about half a metre after the September test, and parts of it shuffled south.
To manage this deformation, the bomb released the energy equivalent to between 109,000 and 276,000 tonnes of TNT in a chamber 450 metres below Mt Mantap’s peak.
The “Fat Man” bomb that exploded over Nagasaki yielded an energy level equivalent to 20,000 tonnes.
Among the data, they found the seismic shivers of a second, smaller event — an aftershock that appeared 700 metres south of, and 8.5 minutes after, the explosion.
The waves produced by the aftershock weren’t consistent with an explosion; rather, it looked like the ground had imploded.
This, the geophysicists suggest, “likely indicates the collapse of the tunnel system of the test site”.
While Dr Wang and his team used data from seismic monitoring systems in China and the surrounding area, Australia has one of the best in the world, Professor Tkalcic said: the Warramunga monitoring station in the Northern Territory, near Tennant Creek.
It’s almost smack bang in the centre of the continent, in an incredibly quiet part of the world, seismically speaking; far from tectonic plate edges, cities and the shoreline, where waves crashing on the coast create seismic noise.
It uses an array of buried instruments to pick up waves that travel through the ground, acting as a giant antenna to amplify weak signals.
“They’re used in the same way as astronomers use arrays of antennas to look at deep space. It’s just that our antennas are pointed to the centre of the earth,” Professor Tkalcic said.
There is also an infrasound detection system at Warramunga station, which detects waves that travel through the atmosphere produced by bomb blasts.
The data is transmitted by satellite to the Comprehensive Nuclear-Test-Ban Treaty Organisation in Vienna, where it is monitored round the clock.
So how do geophysicists know if seismic waves are caused by bomb blasts and not, say, an earthquake or landslide?
In a subterranean explosion, the ground is pushed outwards and compressed, sending a particular type of wave through the ground, Professor Tkalcic said.
An earthquake’s seismic signature is different. If two plates collide, rub against each other or slip, they send out another type of wave.
“We can tell if the first motion was predominantly a compression or if it was a shear type of motion,” Professor Tkalcic said.
In this file photo, the No. 3 reactor, center left, of Shikoku Electric Power Co. Ikata Nuclear Power Station is seen from a Mainichi Shimbun helicopter on March 28, 2017.
IKATA, Ehime — Water containing radioactive materials has leaked from a purification system inside of a stalled nuclear reactor here, Shikoku Electric Power Co. and the Ehime Prefectural Government announced on May 9.
The leak occurred in the auxiliary building of the No. 3 reactor at the Ikata Nuclear Power Station in the town of Ikata, Ehime Prefecture. According to the prefectural government and Shikoku Electric, the coolant water was found to be leaking from the pressure gauge stop valve for the purification system at around 2:10 a.m. on May 9.
The radiation level of the materials in the roughly 130 milliliters of escaped water measured 20 becquerels, far below the standard for filing a report to the central government. The utility and Ehime Prefecture said there is no reported leakage outside of the facility, nor was there any danger posed to employees or the surrounding environment. Regardless, the reason for the leak will be investigated thoroughly.
The No. 3 Reactor at the facility was restarted in August 2016. However, while the rector was undergoing a scheduled inspection in December 2017, a temporary injunction was handed down by the Hiroshima High Court that halted operation at the site.

Japan’s 8th reactor is back online. Kansai Electric Power Company on Wednesday restarted a reactor at the Ohi plant in Fukui Prefecture, central Japan.
At the plant, workers pulled out the control rods that suppress atomic fission of the No.4 reactor.
The facility is expected to reach criticality early Thursday, begin power generation and transmission on Friday and go into commercial operation in early June.
The reactor had complied with new government regulations put in place following the 2011 Fukushima Daiichi nuclear accident.
Two months earlier, the utility reactivated the No.3 reactor at the plant. Two more reactors are running at its Takahama plant about 13 kilometers west of Ohi.
Although they all passed the government’s new regulations, attention is now focused on the threat of multiple accidents at these plants in the event of an earthquake and tsunami.
This summer, the government plans to hold its first drill based on a scenario that accidents have occurred simultaneously at the Ohi and Takahama plants.
In 2014, the Fukui District Court ruled against putting the No.3 and No.4 reactors at Ohi back online. It said estimated tremors of possible quakes at the plant are too optimistic. The ruling was appealed to a higher court, which has yet to decide the issue.
Nuclear Inspectors Would Face Monumental Task in N.Korea http://english.chosun.com/site/data/html_dir/2018/05/08/2018050801221.html By Cho Yi-jun May 08, 2018
The U.S.’ call for a “permanent, verifiable, irreversible dismantlement” of North Korea’s nuclear and ballistic missile programs would pose a monumental task for international inspectors.
U.S. officials project “the most extensive inspection campaign in the history of nuclear disarmament, one that would have to delve into a program that stretches back more than half a century and now covers square miles of industrial sites and hidden tunnels across the mountainous North,” according to the New York Times on Sunday.
The success of any verification hinges on accurately assessing North Korea’s nuclear weapons and missile stockpiles, most of which are hidden away. Already U.S. intelligence agents are going all out to gather data about the North’s nuclear and ballistic missile facilities.
The U.S. National Geospatial-Intelligence Agency recently launched a project that tracks the movements of all vehicles in and out of North Korean military installations, CNN reported. Washington has also monitored North Korean responses to American fighter planes flying overhead to arrive at an overall assessment of the North’s hidden military bases.
One diplomatic source in Washington said the U.S. “may have assessed North Korea’s secret military installations much more accurately than the North thinks.”
The New York Times cited the RAND Corporation as arriving at no better assessment than that North Korea has 20 to 60 nuclear warheads and around 40 to 100 nuclear facilities, while one nuclear facility has more than 400 buildings.
“While there is no question Iran hid much of its weapons-designing past, North Korea has concealed programs on a far larger scale,” the daily said.
The RAND Corporation predicts that it would take 273,000 U.S. troops just to locate and secure North Korea’s weapons of mass destruction, which is more than the number of American soldiers deployed in Iraq at the peak of the U.S. invasion.
It warned that the International Atomic Energy Agency has only 300 inspectors, and 80 of them are already assigned to monitoring activities in Iran. If the North agrees in principle to denuclearize, the IAEA will have a huge task simply finding the personnel.
North Korea could easily conceal highly enriched uranium which could be used to produce a nuclear bomb, and it would be virtually impossible to find if the North fails to cooperate.
Justice Party lawmaker Kim Jong-dae, who recently visited Washington, told reporters that North Korea has “tens of thousands of facilities related to nuclear and missile development, while there are around 10,000 underground tunnels and storage facilities in the Mt. Baekdu area.”
“Realistically, the U.S.-North Korea summit should discuss nuclear arms reduction rather than complete dismantlement,” he added.
Mac Thornberry, head of the U.S. House Armed Services Committee, told Fox New that he is “very skeptical” that North Korea will completely dismantle its weapons of mass destruction and advised the U.S. to “prepare for the worst.”
But others warned that North Korea could face a grim future if it attempts to fool the U.S.
Hardline U.S. lawmaker Lindsey Graham said in a radio interview that North Korea played “every president before -– Clinton, Bush, all of them” but warned that Pyongyang would regret it if it tries to dupe the Trump administration since this would mean the “end of the North Korean regime.”
TOKYO — North Korean leader Kim Jong Un wants to talk to President Trump about “phased and synchronous measures” to deal with the standoff over the North’s nuclear program, Chinese state media reported Tuesday after Kim made his second visit to China in as many months.
This wording, coupled with Kim’s desire to “eventually achieve denuclearization and lasting peace on the peninsula,” will ring alarm bells in Washington as it reinforces suspicions that the North Korean leader will ask Trump to take simultaneous steps to reduce tensions.
The U.S. president said Tuesday in Washington that Secretary of State Mike Pompeo was en route to North Korea to finalize a date and location for a meeting between Trump and Kim. It would be the first such parley between a sitting American president and a North Korean leader.
“This wording about a ‘phased approach’ shows that this is going to be a process,” said Patrick McEachern, a fellow at the Woodrow Wilson Center who previously worked on North Korea at the State Department.
“There are no home runs here. Success in diplomacy with North Korea is going to be a series of singles, with some strikeouts and errors along the way,” he said.
There is considerable skepticism among analysts that Kim, having tried so hard to get a credible nuclear weapons program, is about to give it all up — certainly not without extracting major concessions from the United States. That could include reducing the U.S. military footprint in South Korea.
Kim made the remarks during a two-day visit to the Chinese port city of Dalian, not far from the North Korean border, where he met with President Xi Jinping, Xinhua reported Tuesday night. His younger sister and close aide, Kim Yo Jong, also was seen at the meetings………
South Korea has repeatedly said that the North is willing to discuss its nuclear program in talks with the United States, although “denuclearization” has not been defined. The language in the April 27 agreement has many American analysts worried that Kim will insist on U.S. military drawdowns from South Korea as part of any deal.
Although there is considerable skepticism in the United States and Japan about whether North Korea is genuine in its detente efforts, analysts point out that Kim appears to want to move on from nuclear to economic development.
“I do think North Korea would have a very strong interest to pivot to economic development,” Zhao said. “In this regard, it would have a strong motivation to build much stronger economic ties with China, South Korea and Russia.”
The South Korean government is exploring ways to increase economic cooperation with North Korea without breaching international sanctions or earning the ire of Trump. Reports from the Chinese-North Korean border suggest that Chinese authorities have already lost much of their enthusiasm for enforcing existing sanctions.
(Mainichi Japan) TOKYO –– Construction plans for an anti-terror and emergency response center for the No. 1 reactor at the Kyushu Electric Power Co.’s Sendai nuclear plant were accepted by the Nuclear Regulation Authority (NRA) on May 7.
Formal approval for the emergency center at the plant in Satsumasendai, Kagoshima Prefecture, is expected soon. Nuclear plant operators are required to build emergency response facilities within a certain timeframe under new safety standards that took effect in 2013. The plans for the Sendai plant are the first to be approved by the NRA.
The NRA reviewed a number of Kyushu Electric construction plans for the response center, including for maintenance equipment, and accepted some of them. Details have not been made available for safety reasons, but the center will be built some distance from the Sendai plant’s reactor buildings. With potential terror attacks in mind, the center will be equipped with water pumps, generators and an emergency control room allowing staff to continue to cool the reactors remotely.
The NRA requires that the emergency response centers be strong enough to withstand being struck by an aircraft, or be located a significant distance from a plant’s reactors, and that they have emergency control rooms.
At first, the NRA had demanded that the response centers be established by July this year. However, with many plants unable to meet the deadline, in November 2015 the agency switched to requiring the centers be set up “within five years of the approval of detailed upgrade plans for the reactors themselves.”
So far, the NRA has green-lit the restarts of seven reactors at five plants, which are now all on the deadline clock to open emergency response centers. The Sendai plant’s No. 1 unit is one of those reactors, and Kyushu Electric has until March 2020 to complete the response center there. If it does not meet the deadline, it will be compelled to shut off the No. 1 reactor until the response center is finished. The deadline for the plant’s No. 2 reactor is in May the same year.
The cost of building the response centers has swelled over time, with those for the Sendai plant’s two reactors set to reach roughly 220 billion yen — five times the initial estimate. Kansai Electric Power Co. is also expected to shell out some 222.7 billion yen for response centers for the four reactors at its Takahama nuclear plant in Fukui Prefecture.

The findings come just two weeks ahead of a critical decision at the United Nations Human Rights Council (UNHRC) review on Japan’s human rights record and commitments to evacuees from the nuclear disaster.
“In all of the areas we surveyed, including where people are permitted to live, the radiation levels are such that if it was in a nuclear facility it would require strict controls. Yet this is public land. Citizens, including children and pregnant women returning to their contaminated homes, are at risk of receiving radiation doses equivalent to one chest X-ray every week. This is unacceptable and a clear violation of their human rights, ” said Jan Vande Putte, radiation specialist with Greenpeace Belgium and leader of the survey project.
Greenpeace Japan conducted the investigations in September and October last year, measuring tens of thousands of data points around homes, forests, roads and farmland in the open areas of Namie and Iitate, as well as inside the closed Namie exclusion zone. The government plans to open up small areas of the exclusion zone, including Obori and Tsushima, for human habitation in 2023. The survey shows the decontamination program to be ineffective, combined with a region that is 70-80% mountainous forest which cannot be decontaminated.
Key finding from the Greenpeace Japan survey:
Even after decontamination, in four of six houses in Iitate, the average radiation levels were three times higher than the government long term target. Some areas showed an increase from the previous year, which could have come from recontamination.
At a house in Tsushima in the Namie exclusion zone, despite it being used as a test bed for decontamination in 2011-12, a dose of 7 mSv per year is estimated, while the international limit for public exposure in a non-accidental situation is 1 mSv/y. This reveals the ineffectiveness of decontamination work.
At a school in Namie town, where the evacuation order was lifted, decontamination had failed to significantly reduce radiation risks, with levels in a nearby forest with an average dose rate of more than 10 mSv per year. Children are particularly at risk from radiation exposure.
In one zone in Obori, the maximum radiation measured at 1m would give the equivalent of 101 mSv per year or one hundred times the recommended maximum annual limit, assuming a person would stay there for a full year These high levels are a clear threat, in the first instance, to thousands of decontamination workers who will spend many hours in that area.
This contamination presents a long term risk, and means that the government’s long-term radiation target (1ｍSv/year which is equivalent to 0.23μSv/hour) are unlikely to be reached before at least the middle of the century in many areas that are currently open and into next century for the exclusion zone of Namie. In an admission of failure, the government has recently initiated a review of its radiation target levels with the aim of raising it even higher.
The Government’s policy to effectively force people to return by ending housing and other financial support is not working, with population return rates of 2.5% and 7% in Namie and Iitate respectively as of December 2017.
In November last year, the UNHRC’s Universal Periodic Review (UPR) on Japan issued four recommendations on Fukushima issues. Member governments (Austria, Portugal, Mexico and Germany) called for Japan to respect the human rights of Fukushima evacuees and adopt strong measures to reduce the radiation risks to citizens, in particular women and children and to fully support self evacuees. Germany called on Japan to return to maximum permissible radiation of 1 mSv per year, while the current government policy in Japan is to permit up to 20 mSv per year. If this recommendation was applied, the Japanese government’s lifting of evacuation orders would have be halted.
“Our radiation survey results provides evidence that there is a significant risk to health and safety for any returning evacuee. The Japanese government must stop forcing people to go back home and protect their rights,” said Kazue Suzuki, Energy Campaigner at Greenpeace Japan. “It is essential that the government fully accept and immediately apply the recommendations at the United Nations.”
