Restart of Japan’s tsunami-hit Onagawa nuclear reactor to be OK’d

October 14, 2020

Sendai – A nuclear reactor in northeastern Japan damaged by the 2011 earthquake-tsunami disaster is all but certain to resume operations as the governor of the prefecture hosting the facility has decided to give consent, local officials said Wednesday.

For the No. 2 unit of the Onagawa nuclear plant in Miyagi Prefecture to restart, winning consent from local government leaders is the last remaining step needed after it cleared a national safety screening in February.

Miyagi Gov. Yoshihiro Murai will formally announce his consent by the end of the year, according to the officials, who spoke on condition of anonymity.

By doing so, he would be the first governor of a disaster-hit prefecture to give the green light to the restart of a nuclear reactor.

The other heads of local governments whose consent is essential are the mayors of the city of Ishinomaki and the town of Onagawa where the plant operated by Tohoku Electric Power Co. straddles.

Of them, Ishinomaki Mayor Hiroshi Kameyama has already expressed his willingness to give the nod, and such a move is backed by the two municipalities’ assemblies.

After the quake triggered one of the world’s worst nuclear crises in neighboring Fukushima Prefecture and caused all of Japan’s 54 reactors to halt at one point, nine units at five plants in the country have restarted following regulatory and local approval.

Murai has come to believe residents will support his stance after the prefectural assembly adopted a plea seeking his consent at a panel meeting Tuesday and is set to approve it at a plenary session next week, the officials said.

“When the plenary session shows its stance, I will make a decision upon hearing the opinions of mayors of cities, towns and villages within the prefecture,” Murai said.

The 825,000-kilowatt reactor won the approval of the Nuclear Regulation Authority in February, becoming the second disaster-damaged reactor to pass stricter safety standards after the Fukushima nuclear disaster — the worst since the 1986 Chernobyl accident.

At the Onagawa complex, all three reactors — the same boiling water reactors as in Fukushima — shut down when a massive quake and a 13-meter tsunami hit northeastern Japan on March 11, 2011, flooding the underground floors of the No. 2 unit.

However, the plant’s emergency cooling system did not fail and there was no meltdown of the type that occurred at three of the six reactors at the Fukushima Daiichi plant of Tokyo Electric Power Company Holdings Inc.

Tohoku Electric Power Co. aims to restart the Onagawa No. 2 reactor in 2022 at the earliest, after completing anti-disaster work such as the construction of an 800-meter-long seawall at the plant. It has already decided to scrap the No. 1 unit.

Other boiling water reactors at TEPCO’s Kashiwazaki-Kariwa plant in Niigata Prefecture and the Tokai No. 2 plant of Japan Atomic Power Co. in Ibaraki Prefecture have also won the regulator’s approval to resume operations but have yet to obtain local consent.

Mansion without a toilet: Towns in Japan seek to house, store nuclear waste out of necessity

Oct 12, 2020

Two remote towns in northern Japan struggling with rapidly graying and shrinking populations signed up Friday to possibly host a high-level radioactive waste storage site as a means of economic survival.

Japanese utilities have about 16,000 tons of highly radioactive spent fuel rods stored in cooling pools or other interim sites, and there is no final repository for them in Japan — a situation called “a mansion without a toilet.”

Japan is in a dire situation following the virtual failure of an ambitious nuclear fuel recycling plan, in which plutonium extracted from spent fuel was to be used in still-unbuilt fast breeder reactors. The problem of accumulating nuclear waste came to the fore after the 2011 Fukushima nuclear power plant disaster. Finding a community willing to host a radioactive dump site is difficult, even with a raft of financial enticements.

On Friday, Haruo Kataoka, the mayor of Suttsu town on the northwestern coast of Hokkaido, applied in Tokyo for preliminary government research on whether its land would be suitable for highly radioactive waste storage for thousands of years.

Later Friday in Kamoenai just north of Kamoenai, village chief Masayuki Takahashi announced his decision to also apply for an initial feasibility study.

Suttsu, with a population of 2,900, and Kamoenai, with about 800 people, have received annual government subsidies as hosts of the Tomari nuclear power plant. But they are struggling financially because of a declining fishing industry and their aging and shrinking populations.

The preliminary research is the first of three steps in selecting a permanent disposal site, with the whole process estimated to take about two decades. Municipalities can receive up to 2 billion yen ($19 million) in government subsidies for two years by participating in the first stage. Moving on to the next stage would bring in more subsidies.

“I have tried to tackle the problems of declining population, low birth rates and social welfare, but hardly made progress,” Takahashi told reporters. “I hope that accepting research (into the waste storage) can help the village’s development.”

It is unknown whether either place will qualify as a disposal site. Opposition from people across Hokkaido could also hinder the process. A gasoline bomb was thrown into the Suttsu mayor’s home early Thursday, possibly by an opponent of the plan, causing slight damage.

Hokkaido Gov. Naomichi Suzuki and local fisheries groups are opposed to hosting such a facility.

One mayor in southwestern Japan expressed interest in 2007, but faced massive opposition and the plan was spiked.

High-level radioactive waste must be stored in thick concrete structures at least 300 meters (yards) underground so it won’t affect humans and the environment.

A 2017 land survey map released by the government indicated parts of Suttsu and Kamoenai could be suitable for a final repository.

So far, Finland and Sweden are the only countries that have selected final disposal sites

Japan’s government planning to dump into the sea, the radioactive water from Fukushima No. 1 nuclear reactor

Fukushima No. 1 nuclear plant wastewater looks headed for ocean, THE ASAHI SHIMBUN, October 16, 2020   The government is moving toward the controversial disposal method for contaminated water at the crippled Fukushima No. 1 nuclear power plant of dumping it into the ocean.

Fishermen have fiercely opposed this disposal method at the plant, which experienced a triple meltdown in March 2011 following a magnitude-9.0 earthquake and tsunami, over fears of resulting negative publicity hurting their industry.

The central government is likely to hold a meeting of relevant Cabinet ministers before the end of October to make a formal decision on the dumping, sources said.

Before being dumped into the ocean, the stored water would be processed a second time and diluted with seawater to lower levels of radioactive materials below legally established standards.

It is expected to take about two years to prepare for the dumping process.

Water contaminated with radioactive materials continues to be produced at the Fukushima No. 1 plant at a daily rate of about 140 tons. Water used to cool melted spent nuclear fuel mixes in with groundwater that leaks into the reactor building.

Tokyo Electric Power Co., the operator of the plant, treats the contaminated water using equipment called advanced liquid processing systems, or ALPS, before storing the water in tanks on the plant grounds.

But about 1.2 million tons of processed water is being stored in tanks and TEPCO has estimated that tank capacity will be reached by the summer of 2022 even under the current plan to build more tanks.

Because about two years is needed to construct the necessary equipment to dispose of the contaminated water and to pass screening by the Nuclear Regulation Authority, a decision on disposal of the water was expected by this summer.

A subcommittee of experts set up by the economy ministry compiled a proposal in February that said the two realistic alternatives were to dump the water into the ocean or release it into the atmosphere. The panel added that dumping the water into the ocean was the method that could be implemented with certainty.

Since April, the government has conducted seven hearings involving local government officials, farming and fisheries organizations and business groups on the issue………   http://www.asahi.com/ajw/articles/13831640

Japan’s government ignores U.N. nuclear ban treaty, puts out feeble anti-nuclear weapons resolution

Japan submits anti-nuclear resolution with no mention of ban pact,  https://www.japantimes.co.jp/news/2020/10/16/national/japan-un-nuke-resolution-ban-pact/ NEW YORK – Japan submitted an anti-nuclear resolution to a panel at the United Nations on Thursday, but the text made no direct reference to a U.N.-adopted nuclear ban treaty likely to go into effect early next year.

Opting not to mention the Treaty on the Prohibition of Nuclear Weapons, which is expected to cross the needed threshold of ratification soon and take effect 90 days later, apparently reflects Japan’s ties with the United States, its key security ally which opposes the pact and provides security assurances to Japan under its so-called nuclear umbrella.

Tokyo’s stance on the matter appears to have remained unaltered after the first change to the country’s leadership in nearly eight years, with Prime Minister Yoshihide Suga replacing former Prime Minister Shinzo Abe last month.

As the only country in the world to have suffered atomic bombings, Japan has submitted an anti-nuclear resolution to the United Nations every year since 1994. But versions of the annual resolution submitted since the nuclear ban pact was adopted in 2017 make no mention of it.

So far, 47 countries and regions have completed ratification procedures for the nuclear ban treaty, with a total of 50 ratifications needed for it to take effect.

Japan opposed the nuclear ban pact along with the five permanent members of the U.N. Security Council, which are all nuclear powers.

The nation’s latest resolution preserves phrasing from last year about the devastating humanitarian impacts of nuclear weapons, which was worded less strongly than previous versions that until 2018 expressed deep concern on the matter.

Japan’s resolution is likely to pass the U.N. General Assembly’s First Committee on disarmament issues by early November before being adopted at the General Assembly by the end of the year.

North Korea, with its new intercontinental-range ballistic missile makes it clear that it is a nuclear weapons nation

A Nuclear North Korea’s Wake-up Call, A spectacular pre-dawn parade on Saturday served to remind the world of North Korea’s continuing missile progress.  The Diplomat, By Ankit Panda, October 13, 2020  On Saturday, October 10, North Korea celebrated the 75th anniversary of the founding of the Workers’ Party of Korea (WPK), the country’s ruling party. The occasion was celebrated in a grand way, with an unprecedented pre-dawn military parade. Thousands of uniformed military personnel marched through Pyongyang’s renovated Kim Il Sung Square in perfect unison, trailed by scores of heavy military vehicles……..

A ‘New Strategic Weapon,’ As Promised

The parade reached its climax with the reveal of an all-new intercontinental-range ballistic missile (ICBM) design. Prior to the parade, North Korea’s largest known nuclear-capable ballistic missile was the Hwasong-15, the ICBM that was tested for the first (and so far only) time in November 2017. After four Hwasong-15s rolled through Kim Il Sung Square, an even larger missile appeared in its wake. Four of these super-large ICBMs followed in the wake of the Hwasong-15s, in a single file formation. Not only were these missiles the largest ever to be seen in North Korea, they were the largest road-mobile missiles on integrated launchers seen anywhere in the world……….

For the United States, this missile is not good news. Not only does it underscore the failure of the Trump administration’s diplomatic attempts to constrain North Korea’s nuclear and missile programs; it also emphasizes the continuing growth of Pyongyang’s qualitative capabilities. A lot remains unknown about the precise capabilities of this new missile, but its sheer size certainly implies that it would be capable of carrying and delivering multiple nuclear reentry vehicles to likely the entire continental U.S. As North Korea’s weapons-grade fissile material stocks continue to grow, it likely will have enough fissile material on hand to justify allocating resources toward a multiple reentry vehicle capability. ………

By adding warheads to its ICBMs, North Korea will improve the probability that at least one of its thermonuclear reentry vehicles successfully penetrates U.S. missile defenses. To keep up with changes in North Korea’s growing force, the U.S. will have to spend hundreds of millions adding interceptors. North Korea, meanwhile, even under economic sanctions, appears fully capable of continuing to expand its ICBM capabilities………

Despite the nighttime setting, Kim’s reveal of his new ICBM made it clear as day that North Korea remained a capable and growing nuclear state………

What the parade does in the end is clarify the big picture about North Korea’s status as a nuclear weapons possessor: its nuclear forces grow larger and more refined with every passing week. Having largely crossed the qualitative thresholds it felt were needed for a rudimentary and minimally credible deterrent in 2017, Pyongyang is continuing to evolve its force.

Ikata nuclear reactor to be shut down – 40 year decommissioning process

Regulator approves Ikata 2 decommissioning plan

Japan’s Nuclear Regulation Authority (NRA) today approved Shikoku Electric Power Company’s decommissioning plan for unit 2 of its Ikata nuclear power plant in Ehime prefecture. Decommissioning of the unit is expected to be completed by 2059.

The three-unit Ikata plant

07 October 2020

Ikata 2 is a 538 MWe pressurised water reactor that began operating in March 1988. It was taken offline in January 2012 for periodic inspections. Shikoku announced in March 2018 that it did not plan to restart the reactor. It said the cost and scale of modifications required to upgrade the 40-year-old unit to meet the country’s revised safety standards made it uneconomical to restart it.

The utility submitted an outline of its plans for decommissioning the unit to the NRA on 10 October, 2018. Shikoku also submitted requests to Ehime prefecture and the municipality of Ikata, as specified under nuclear safety agreements concluded with those authorities.

Following a review, which included a total of seven public meetings, the NRA has today approved the decommissioning plan for Ikata 2.

According to the plan, decommissioning of the unit will take about 40 years and will be carried out in four stages. The first stage, lasting about 10 years, will involve preparing the reactor for dismantling (including the removal of all fuel and surveying radioactive contamination), while the second, lasting 15 years, will be to dismantle peripheral equipment from the reactor and other major equipment. The third stage, taking about eight years, will involve the demolition of the reactor itself, while the fourth stage, taking about seven years, will see the demolition of all remaining buildings and the release of land for other uses.

During the first stage, all fuel is to be removed from the unit. This includes 316 used fuel assemblies that will be sent for reprocessing and 102 fresh fuel assemblies that will be returned to the fuel fabricator.

“In the future, we will obtain the consent of Ikata Town and Ehime Prefecture, based on the safety agreement,” Shikoku said.

Shikoku decided in March 2016 to decommission unit 1 of the Ikata plant, also a 538 MWe PWR, which began commercial operation in September 1977. That unit had been taken offline in September 2011 for periodic inspections. Upgrades costing more than JPY170 billion (USD1.5 billion) would have been needed at the unit in order for it to operate beyond 40 years. The NRA approved Shikoku’s decommissioning plan for Ikata 1 in June 2017. That plan also sees the unit being decommissioned in four stages over a 40-year period.

The utility said, “As with unit 1, we will steadily proceed with the decommissioning of unit 2 with the highest priority given to ensuring safety.”

China backs Iran nuclear deal, calls for new MidEast forum

China backs Iran nuclear deal, calls for new MidEast forum Bangkok Post, : 11 OCT 2020 BEIJING: China’s foreign minister Wang Yi has called for a new forum to defuse tensions in the Middle East after a meeting with his Iranian counterpart where he reiterated Beijing’s support for Tehran.

Wang and Javid Zarif also reaffirmed their commitment to Iran’s 2015 nuclear deal with world powers, according to the Chinese foreign ministry, an implicit rebuke of the United States for abandoning the accord during their Saturday meeting in China’s southwestern Tengchong city.

Iran has been locked in an acrimonious relationship with Saudi Arabia, the other major Middle Eastern power, over the war in Yemen, Iranian influence in Iraq and Saudi support for Washington’s sanctions on Tehran.

“China proposes to build a regional multilateral dialogue platform with equal participation of all stakeholders,” said the Chinese foreign ministry statement. …… https://www.bangkokpost.com/world/2000307/china-backs-iran-nuclear-deal-calls-for-new-mideast-forum

Kim Jong Un showcases North Korea’s biggest intercontinental missile

Kim Jong Un unveils North Korea’s biggest intercontinental missile
Pyongyang advances its weapons technology despite impact of sanctions and coronavirus,
Edward White, 11 Oct 20,

 Kim Jong Un has unveiled North Korea’s biggest ever intercontinental ballistic missile, highlighting his determination to develop the nation’s nuclear weapons capability despite tough international sanctions. The new long-range missile was revealed at a two-hour military parade, held at Kim Il Sung Square that also showcased new technology across smaller weaponssystems.  
………Mr Kim’s showcasing of his military prowess comes as international experts say North Korea is facing its worst economic crisis in at least 10 years. Strictly enforced coronavirus-related border closures have led to a plunge in trade with China and the country has been hit by extreme flooding, exacerbating the severe hit to state finances stemming from several years of tough US and UN sanctions.  ………

  The reminder of the nuclear threat posed by Mr Kim comes against a backdrop of stalled talks between Pyongyang and Washington — despite three meetings in two years with US president Donald Trump. The two sides have failed to agree on a plan that encompasses US demands for Mr Kim to give up his nuclear weapons and North Korea’s insistence that the Trump administration and the UN ease sanctions. With the US election just weeks away there is rising uncertainty over the US approach to North Korea under a potential Biden administration.  ……… https://www.ft.com/content/2a7b7ec0-1cd5-4b4a-bb03-0a0f5333ea37

Fishing industry chief opposes releasing Fukushima No. 1 water into sea

Fishing industry chief opposes releasing Fukushima No. 1 water into sea, https://www.japantimes.co.jp/news/2020/10/09/national/zengyoren-fukushima-water-sea/ 9 Oct 20, The head of the National Federation of Fisheries Cooperative Associations, or Zengyoren, has voiced strong opposition against releasing treated water containing radioactive tritium from the disaster-stricken Fukushima No. 1 nuclear plant into the sea.

“We are absolutely against ocean release” as a way to dispose of tainted water at Tokyo Electric Power Company Holdings Inc.’s nuclear plant in Fukushima Prefecture, Hiroshi Kishi, head of Zengyoren, said Thursday at a government hearing in Tokyo.

Kishi said that fishermen who are operating along the coast of Fukushima have been suffering from problems caused by the radioactive fallout from the 2011 meltdowns at the plant, such as fishing restrictions, as well as malicious rumors about the safety of farm and marine products there.

If the government chooses to release radioactive water into the sea, a leading option to get rid of accumulating low-level radioactive water at the plant, it will trash all efforts fishermen have so far made to sweep away such rumors and consequently “will have a devastating impact on the future of Japan’s fishing industry,” Kishi stressed.

Toshihito Ono, head of the prefecture’s fishery product processors association, who joined the hearing via a video call, warned that Fukushima’s processed marine products, including products that use ingredients from other prefectures, will become targets of harmful rumors.

In a report released in February, a government panel pointed out that a realistic option would be releasing the tainted water into the ocean after dilution or into the air through evaporation.

Many people fear that both methods will add to the reputational damage suffered by Fukushima products. But treated water storage at the power plant is expected to reach full capacity as early as autumn 2022.

After the hearing, state industry minister Kiyoshi Ejima told reporters, “We find it unadvisable to put off a decision on how to dispose of the water because not much room is left at the plant for tanks containing the water.”

This was probably the last hearing on the water issue, people familiar with the matter said.
