The News That Matters about the Nuclear Industry Fukushima Chernobyl Mayak Three Mile Island Atomic Testing Radiation Isotope

Debris extracted from Fukushima nuclear plant revealed to media

Friday, Feb. 21,  https://www3.nhk.or.jp/nhkworld/en/news/20250221_08/?fbclid=IwY2xjawInSAlleHRuA2FlbQIxMQABHSRSw2PSosgQ6p28ndBqzler46N1Sr9mAHZH_X5SQL5hfjsJ5Tr3M48JTg_aem_xXho8cY6EkFQUvxp6aOcZQNuclear fuel debris that was extracted from the damaged Fukushima Daiichi nuclear power plant last year has been revealed to reporters for the first time.

The debris taken from the plant’s No.2 reactor consists of molten fuel mixed with surrounding structural components. The operator, Tokyo Electric Power Company, successfully retrieved 0.7 grams of the material in its first test extraction operation through November last year.

The debris was first transferred to a research facility of the Japan Atomic Energy Agency in Oarai Town, Ibaraki Prefecture, for the initial analysis, including surface observation.

The researchers then split the debris into smaller pieces to be examined at five research facilities, including a large one in Hyogo Prefecture.

Reporters were given the opportunity to observe the samples, which were placed in two separate transparent containers at a facility in Ibaraki Prefecture. One container held a particle about 2 millimeters in size that appeared silver, while the other had multiple dark fragments.

So far, the researchers have detected uranium, which is contained in nuclear fuel, on the surface of the debris, as well as metals such as iron, which are believed to have come from the reactor’s structure.

The researchers plan to examine the characteristics of the debris, including its hardness and adhesiveness. They will also expose the samples to lasers to determine whether the uranium inside is prone to triggering a nuclear fission reaction.

The agency says it will use these analyses to evaluate potential methods for full-scale extraction of the debris, and to determine the risk of a renewed criticality event, in which a self-sustaining chain reaction could occur.

The agency plans to release the findings of the major analyses in the middle of this year.

Ogino Hideki, the chief engineer at the agency’s Collaborative Laboratories for Advanced Decommissioning Science, spoke to the reporters.

He said it is difficult to fully grasp the overall characteristics of the debris based on the ongoing analyses alone. But he expressed his commitment to contributing to the decommissioning efforts through analyzing the samples using the technology that he and his fellow researchers have developed.

It is estimated that there is a total of around 880 tons of fuel debris in the No. 1, 2 and 3 reactors.

5.0-magnitude quake strikes off Japan’s Fukushima: JMA

TOKYO, Feb. 21 (Xinhua)  https://english.news.cn/20250221/1a62306993674102b4bf547c66308416/c.html?fbclid=IwY2xjawInSGJleHRuA2FlbQIxMQABHaLmlIJlO8LIDD4_tC9mDYzpZnPQTSalQEzW0hj-j5vNUxWQ8hVw_Wrelw_aem_JSAQL14AGKbnrwbZ10cXPA

— An earthquake with a preliminary magnitude of 5.0 struck off the northeastern Japanese prefecture of Fukushima on Friday, the country’s weather agency said.

The temblor occurred at around 10:01 p.m. local time at a depth of 50 km, measuring 4 on the Japanese seismic intensity scale of 7, according to the Japan Meteorological Agency (JMA).

The epicenter was located at a latitude of 37.5 degrees north and a longitude of 141.5 degrees east.

There was no tsunami warning, the JMA added

Japan to pick final disposal sites for Fukushima soil around 2030

 https://www.japantimes.co.jp/news/2025/02/12/japan/fukushima-disposal-sites/?fbclid=iwy2xjawieatflehrua2flbqixmqabhsg4y7avwtfefjq31d1xggrkcnxelunlv4sc3intwhnzq4htdltaeaqxvq_aem_es-i9dwwgmqvbhmm2rxeag

The Environment Ministry plans to decide around 2030 or later where to finally dispose of soil removed from the ground during decontamination work after the March 2011 disaster at Tokyo Electric Power Company Holdings’ Fukushima No.1 nuclear power plant, it was learned Wednesday.

The plan was included in a draft timetable for the final disposal of such soil outside Fukushima Prefecture by March 2045, presented by the ministry at a meeting of a related expert panel on the day. The ministry will consider a process for selecting final disposal sites from fiscal 2025.

As of the end of December, about 14 million cubic meters of such soil had been transported to an interim storage facility straddling the Fukushima towns of Okuma and Futaba.

Three-quarters of the soil had radiation concentrations of 8,000 becquerels per kilogram or less and will be reused in public works, while the rest will be subject to final disposal.

Final disposal sites are estimated to require up to 50 hectares if the volume of the soil is not reduced, or 2 to 3 hectares if the volume is reduced. Meanwhile, radiation levels would be higher in the reduced soil.

The government is slated to draw up a basic plan as early as this spring for reusing some of the soil and finally disposing of the rest.

India PM Modi ends foreign tour with nuclear deals in pipeline

By AFP, 14 February 2025 Daily Mail

Indian Prime Minister Narendra Modi concluded a whistle-stop diplomatic tour Friday having secured significant pledges of support from Washington and Paris to help step up his country’s nuclear energy programme.

New Delhi has vowed to achieve net zero carbon emissions by 2070 partly by increasing the number of nuclear plants in the country from eight, which currently account for around three percent of power generation in India.

Modi’s White House meeting with President Donald Trump resulted in an agreement to build US-designed nuclear reactors in India.

“This path forward will unlock plans to build large US-designed reactors and enable collaboration to develop, deploy and scale up nuclear power generation with advanced small modular reactors,” a joint statement said Thursday.

India revealed a similar deal with France following Modi’s meeting with President Emmanuel Macron earlier this week.

Foreign secretary Vikram Misri said Wednesday that India and France aimed to initiate cooperation on developing small modular nuclear reactors, nothing that the technology was still in its “initial stages”.

“Our intent is to be able to cooperate in co-designing the reactors, co-developing them, and co-producing them,” he told reporters.

Both partnerships come days after Modi’s government announced plans to amend its strict nuclear liability law, which holds operators liable for any damage or accident, with exceptions made for certain situations including natural disasters……………………… https://www.dailymail.co.uk/wires/afp/article-14396859/India-PM-Modi-ends-foreign-tour-nuclear-deals-pipeline.html

Kansai Electric to ship more spent nuclear fuel to France

Fukui  Japan Times 9th Feb 2025 https://www.japantimes.co.jp/news/2025/02/09/japan/japan-more-spent-nuke-fuel-to-france/

Kansai Electric Power is working to double the amount of spent nuclear fuel it will ship to France, increasing it by about 200 tons, informed sources said.

The move comes as Fukui Prefecture, home to several nuclear plants, urges Kansai Electric to address shrinking storage capacity for spent nuclear fuel, the sources said.

In 2023, Kansai Electric announced a plan to ship about 200 tons of the fuel from its Takahama plant in Fukui to France starting in fiscal 2027. Based on the Japanese government’s policy, the spent fuel will be used for research on technology to reprocess uranium-plutonium mixed oxide, or MOX, fuel.

At the Takahama plant, about 90% of the spent fuel storage capacity has already been used, and that amount is expected to reach the upper limit in about three years.

About 200 tons of spent fuel will be generated if the No. 1 to No. 4 reactors at the plant are operated for about three years. Kansai Electric has restarted all of its seven nuclear reactors.

The company initially planned to send spent fuel mainly to a reprocessing plant to be built in Aomori Prefecture, but the completion of the facility has been postponed.

Last September, the company notified Fukui Gov. Tatsuji Sugimoto of its intention to review the plan, and said that it would halt three reactors in the prefecture if it fails to come up with a proposal that can win the understanding of officials there by the end of fiscal 2024.

North Korean leader Kim Jong Un vows to further develop nuclear forces

Alarabiya, 9 Jan 25

North Korean leader Kim Jong Un criticized trilateral military cooperation among the United States, Japan and South Korea for raising tensions in the region and vowed countermeasures, including the further development of nuclear forces.

Kim said US deployments of nuclear strategic assets, war exercises and military cooperation with Japan and South Korea were inviting military imbalance in the region and raising a grave challenge to the security environment, state media KCNA reported on Sunday.

“The DPRK does not want unnecessary tension of the regional situation but will take sustained countermeasures to ensure the regional military balance,” Kim said during a visit to the defense ministry on Saturday to commemorate the founding day of its Army.

DPRK stands for the Democratic People’s Republic of Korea, North Korea’s official name.

US President Donald Trump, after a meeting on Friday with Japanese Prime Minister Shigeru Ishiba, said he would have relations with North Korea, as they expressed concern over its nuclear program.

But during the visit, Kim “clarified once again the unshakable policy of more highly developing the nuclear forces,” according to the report……………………………….

In a separate commentary released later on Sunday, North Korea’s KCNA again criticized South Korea’s military activity with the United States this year and warned that aggressive actions would be met by undesired consequences.

“Anyone could easily guess how we would take the fact that they carried out war exercises that were more intense than ever before at a time when diplomacy schedules were being canceled due to political turmoil,” KCNA said.  https://english.alarabiya.net/News/world/2025/02/09/north-korean-leader-kim-jong-un-vows-to-further-develop-nuclear-forces

As China and the U.S. Race Toward A.I. Armageddon, Does It Matter Who Wins?

it doesn’t matter if the U.S. has no real enemies. The military industrial complex must continue to unceasingly grow, according to the logic of the Megamachine. It will invent enemies in order to justify that growth. That’s why we now have thousands of nuclear bombs and a sprawling, AI-driven, globally networked satellite and base infrastructure that encases the Earth like an iron maiden.

Koohan  Paik-Mander CounterPunch , 7 Feb 25

A longstanding Sinophobia in the U.S. goes back to the 19th century, with the Chinese Exclusion Act, the tax on Chinese miners during the Gold Rush, and the exclusion from being able to testify in court.

Evidence of this entrenched history lingers today, in the trade sanctions against China, belligerent rhetoric from both Republicans and Democrats that led to a rash of violence against elderly Asian-Americans on American streets, as well as billions of dollars spent to fortify overseas bases in preparation for a U.S.-China war.

And the refusal to cooperate meaningfully with China on anything. As a result, the U.S. is thick in the midst of an AI arms race with China that is predicated on both nations’ dangerous faith in techno-salvation.

Thanks to the legacy of Sinophobia, it takes a whole lot to elicit an overwhelming embrace of China from average Americans, even if temporarily. But that’s what’s happened twice in the last month. The first time was the TikTok fiasco, when millions of distraught TikTok users had had their favorite platform snatched from them like a pacifier from a baby’s mouth. They found solace not in Meta nor X (as had been the plan), but rather, in the Chinese social media platform, Xiaohongshu, also known as “RedNote.”

The second instance was the debut of DeepSeek AI, which came on the heels of one of the most pompous pageants of delusional grandeur ever seen. It was Trump’s inauguration ceremony for his second term. Shortly thereafter, a press conference was held. Three tech oligarchs and the president bloviated about their Stargate AI project. It would cost $500 billion. That’s what they say is needed to stay ahead of the Chinese. (For some reason, the excuse of “staying ahead of the Chinese” seems to justify any astronomical expense.)

In the mean time, thousands of people have been left homeless due to wild fires in L.A., flooding in North Carolina, and even to this day, people from Lahaina, Maui are still without a place to call home. But none of these Americans got a press conference.

Instead, it was the oligarchs who took the stage. Oracle’s Larry Ellison, Masayoshi Son of Starbank, and Open AI founder Sam Altman described Stargate’s plans to build clusters of gigantic data centers across the country from sea to shining sea, each one bigger than any Walmart Superstore. It’s Manifest Destiny for data.

No one at the press conference mentioned that many of the data centers would be built on federal lands, would collectively use as much power as small European nations, require massive volumes of water, or would require a network of nuclear reactors.  They did make the dubious promise their AI would cure cancer and heart disease. I think the guys who got wampum for Manhattan got a better deal.

A few days afterward, as if on cue, a Chinese company called DeepSeek that no one had ever heard of dropped their bombshell. The Chinese firm had released its own AI that was open-source, used fifty times less energy, performed on par with all the American AIs, and cost a gazillion times less to produce. Suddenly, the mirage of Silicon Valley’s invincibility faded away to reveal an overvalued industry that had gotten too fat, lazy and full of itself to innovate anything except marketing promises to investors. The very next day, a veritable trillion dollars peeled like a banana off the U.S. stock exchange tech sector. The story everywhere was that Chinese AI had officially “caught up” with the U.S.

When people cheered the scrappy Chinese underdog, it was as much a middle finger to the overblown hubris of the tech oligarchs as it was an embrace of Chinese innovation. It was motivated largely by the same class anger that rose up to lionize Luigi Mangione for killing a health insurance CEO with three inscribed bullets. People had been galled by the consolidated display of the broligarchy on the dais at the Trump inauguration, similar to the royals waving at the minions from the balcony at Buckingham Palace. Their message was unequivocal: We own you.

DeepSeek has been described as a Robin Hood of tech, taking from the rich to give AI to the poor. Sentiments of class anger buoyed admiration for the unknown company from China. They disregarded, for once, the stubborn stains of Sinophobia.

What was also overlooked in the midst of DeepSeek’s dazzling display of stock market disruption was responsible restraint around technology. As both China and the U.S. go hurtling ever faster toward Armageddon in the race to dominate in AI, they have both bought into techno-utopian ideologies, lock, stock and barrel………………………………………………………………….

China and the U.S. are entangled in a geopolitical rivalry, with existential stakes. Sure, it’s satisfying to enjoy the smarting blow that newcomer DeepSeek landed to the capitalist Goliath — China one, U.S. zero. But it’s not a boxing match. Such narrow framing loses sight of the fact that the race for accessible AI is a race for Mutually Assured Destruction (MAD).

………………………………………………………………………………………………………………The weapons industry wouldn’t tolerate the thought of degrowth, just like Microsoft, Google, Meta, Amazon et al. can’t bear it today. The war industry dealt with it by instead aggressively manufacturing enemies and reasons for war faster than it could manufacture more weapons. Now, forty years after the end of the Cold War with Russia, the war budget has increased every year and is now up to one trillion dollars, Los Alamos has begun manufacturing nukes for the first time in decades last year, we’ve got 800 bases around the world, rocket launchpads in wilderness areas, and thousands of satellites in the heavens.

It’s hard to get one’s bearings, especially in the midst of the engineered political maelstrom of the current moment. Fortunately, the books haven’t been burned (yet), so we can turn to the thinkers of the recent past for guidance.

The technology critics of the 20th century, such as Jacques Ellul, Lewis Mumford and Chellis Glendinning, urged us to conceptualize technology not just as a single artifact, such as a laptop, or just AI, or just a satellite, or just a nuclear weapon, but rather, as a whole way of thinking, a way of organizing society, our institutions, a way of being. Technology is not a one-off. It is systemic. Lewis Mumford called all of our technological society the Megamachine.

Every project, technology, organization, and endeavor is an expression of the Megamachine where the economic-growth imperative reigns supreme. It is all of a piece. It doesn’t matter if DeepSeek uses less energy. The growth imperative must be met……

Likewise, it doesn’t matter if the U.S. has no real enemies. The military industrial complex must continue to unceasingly grow, according to the logic of the Megamachine. It will invent enemies in order to justify that growth. That’s why we now have thousands of nuclear bombs and a sprawling, AI-driven, globally networked satellite and base infrastructure that encases the Earth like an iron maiden.

The poster child for the Megamachine in the digital age is Amazon. Former chair of the Federal Trade Commission Lina Khan’s seminal essay “Amazon’s Anti-trust Paradox,” tracks the logic of the behemoth’s growth over its history. She brilliantly unravels how Amazon decisively prioritized sheer growth over profit for its first eight years. The goal was to entrench a broad-spanning networked infrastructure that would guarantee a monopoly and continue to consolidate market dominion. They forwent profits for almost a decade expressly in order to monopolize the market. Again, the imperative for growth and global domination trumps decent common sense.

……………………………………………………………The sooner that the U.S. and China treat one another as fellow members of humankind, rather than adversaries, the real work of cooperation can begin. Both nations are home to millions of indigenous peoples who carry the know-how for surviving and thriving for generations into the future. Their wisdom is more precious than any AI. There’s no shortage of problems that our combined brilliance can improve if not solve: climate, nuclear weapons, species extinction, toxic waste clean-up, housing, microplastics, and last but not least, dangerous unregulated technologies. None of these colossal crises can be addressed as long as we are pointing fingers while locked in the downward spiral of a competition for global hegemony that the U.S. can never win.

Some of us remember the shining moment in history when the U.S. and Soviet Union built trust and signed a raft of nuclear arms control agreements. They modeled what ratcheting down tensions and the path to peace looks like. It would behoove the U.S. and China to follow their lead today, not only with nukes but also with AI and other emerging technologies.  https://www.counterpunch.org/2025/02/07/as-china-and-the-u-s-race-toward-a-i-armageddon-does-it-matter-who-wins/

40% of workers cite radiation concerns at Fukushima plant

By KEITARO FUKUCHI/ Asahi Shimbun, Staff Writer, February 2, 2025 

Forty percent of the workforce at the crippled Fukushima No. 1 nuclear plant worry about radiation issues on the job, a nearly three-fold spike over the previous year, a survey found.

More than half of those respondents cited fears of their body coming into contact with a radioactive substance.

Tokyo Electric Power Co., the plant operator that conducted the annual survey, said recent incidents at the plant probably contributed to the heightened concerns.

For example, two workers were hospitalized in October 2023 after they were accidentally splashed with waste liquid containing highly radioactive substances while cleaning piping in a contaminated water treatment facility.

The survey was carried out between September and October to improve the working environment. TEPCO distributed a questionnaire to all workers at the plant and received responses from 5,498 individuals, or 94.5 percent……………………….

Asked to choose specific issues they were concerned about, 52.2 percent, the largest percentage, picked “physical contamination,” up about seven points from 2023.

In another incident, about 1.5 tons of contaminated water flowed out of a water purification facility at the plant through an air exhaust opening in February 2024…… more https://www.asahi.com/ajw/articles/15609878

China AI startup rattles US new nukes plan

January 30, 2025,  https://beyondnuclear.org/china-ai-startup-rattles-us-new-nuke-plan/

Innovative computer modelling with AI doesn’t need the most expensive and dangerous energy from nukes

The much touted second-coming of a “nuclear renaissance” in the United States fueled by the projected soaring global demand to power artificial intelligence (AI) just got a major setback with the surprise January 20, 2025 overnight emergence of an apparently more competitive and efficient Chinese AI startup company, DeepSeek. The US stock market plummeted for the S&P 500 nuclear power companies that have been financially scaling up as the most reliable 24/7 electricity supply for a massive expansion of energy intensive data centers. China’s surprise rollout of DeepSeek and sudden rise to international acclaim at the start of 2025 has seriously disrupted the US claim to global dominance in cloud computing, networking and data storage services powered by extravagantly expensive atomic energy.

US-based AI technology firms, including Nvidia, which lost nearly $600 billion in the January 27th record breaking single day’s largest stock selloff, have led the way in rebranding nuclear power as the preferred choice as the 24/7 power supplier for a massive AI surge. The sudden emergence of DeepSeek, only two months in the making, is being compared to a “sputnik moment” for the US AI market, referencing the former Soviet Union’s launch of the first artificial satellite into orbit in 1959 that triggered a US technological panic and launched America into a “space race” with Russia. DeepSeek has just as suddenly now laid claim to competitively take the technological lead to advance mere computer modelling to an innovative era of computer reasoning.

Starting in 2023 and swelling in 2024, there was sort of a “gold rush” of fast money that sprang up to finance AI deals with new reactor licensing and construction of still unproven Small Modular Reactor (SMR) designs as well as repowering uneconomical, permanently closed reactors like Three Mile Island Unit 1. The Big Tech corporate promotion was primarily driven by the leading hyperscalers including GoogleAmazonMicroSoftMeta Platforms (aka Facebook) and Oracle. A series of deals have since been cut with the established S&P 500 nuclear corporations led by Constellation EnergyVistra, and the usual suspects of nuclear start-ups including Oklo PowerNuScaleTalen Energy Corp and TerraPower.

However, like a bolt from the blue, the US nuclear industry has been rattled on the stock market.  The S&P 500 nuclear power giants Constellation Energy (CEG) and Vistra (VST) are under scrutiny as international energy analysts reevaluate the energy needs of AI data centers along with that same host of nuclear power start-ups.

DeepSeek: how a small Chinese AI company is shaking up US tech heavyweights.

DeepSeek’s models and techniques have been released under the free MIT License, which means anyone can download and modify them.

https://www.sydney.edu.au/news-opinion/news/2025/01/29/deepseek-ai-china-us-tech.html January 28, 2025 

Chinese artificial intelligence (AI) company DeepSeek has sent shockwaves through the tech community, with the release of extremely efficient AI models that can compete with cutting-edge products from US companies such as OpenAI and Anthropic.

Founded in 2023, DeepSeek has achieved its results with a fraction of the cash and computing power of its competitors.

DeepSeek’s “reasoning” R1 model, released last week, provoked excitement among researchers, shock among investors, and responses from AI heavyweights. The company followed up on January 28 with a model that can work with images as well as text.

What DeepSeek did

In December, DeepSeek released its V3 model. This is a very powerful “standard” large language model that performs at a similar level to OpenAI’s GPT-4o and Anthropic’s Claude 3.5.

While these models are prone to errors and sometimes make up their own facts, they can carry out tasks such as answering questions, writing essays and generating computer code. On some tests of problem-solving and mathematical reasoning, they score better than the average human.

V3 was trained at a reported cost of about US$5.58 million. This is dramatically cheaper than GPT-4, for example, which cost more than US$100 million to develop.

DeepSeek also claims to have trained V3 using around 2,000 specialised computer chips, specifically H800 GPUs made by NVIDIA. This is again much fewer than other companies, which may have used up to 16,000 of the more powerful H100 chips.

On January 20, DeepSeek released another model, called R1. This is a so-called “reasoning” model, which tries to work through complex problems step by step. These models seem to be better at many tasks that require context and have multiple interrelated parts, such as reading comprehension and strategic planning.

The R1 model is a tweaked version of V3, modified with a technique called reinforcement learning. R1 appears to work at a similar level to OpenAI’s o1, released last year.

DeepSeek also used the same technique to make “reasoning” versions of small open-source models that can run on home computers.

This release has sparked a huge surge of interest in DeepSeek, driving up the popularity of its V3-powered chatbot app and triggering a massive price crash in tech stocks as investors re-evaluate the AI industry. At the time of writing, chipmaker NVIDIA has lost around US$600 billion in value.

How DeepSeek did it

DeepSeek’s breakthroughs have been in achieving greater efficiency: getting good results with fewer resources. In particular, DeepSeek’s developers have pioneered two techniques that may be adopted by AI researchers more broadly.

The first has to do with a mathematical idea called “sparsity”. AI models have a lot of parameters that determine their responses to inputs (V3 has around 671 billion), but only a small fraction of these parameters is used for any given input.

However, predicting which parameters will be needed isn’t easy. DeepSeek used a new technique to do this, and then trained only those parameters. As a result, its models needed far less training than a conventional approach.

The other trick has to do with how V3 stores information in computer memory. DeepSeek has found a clever way to compress the relevant data, so it is easier to store and access quickly.

What it means

DeepSeek’s models and techniques have been released under the free MIT License, which means anyone can download and modify them.

While this may be bad news for some AI companies – whose profits might be eroded by the existence of freely available, powerful models – it is great news for the broader AI research community.

At present, a lot of AI research requires access to enormous amounts of computing resources. Researchers like myself who are based at universities (or anywhere except large tech companies) have had limited ability to carry out tests and experiments.

More efficient models and techniques change the situation. Experimentation and development may now be significantly easier for us.

For consumers, access to AI may also become cheaper. More AI models may be run on users’ own devices, such as laptops or phones, rather than running “in the cloud” for a subscription fee.

For researchers who already have a lot of resources, more efficiency may have less of an effect. It is unclear whether DeepSeek’s approach will help to make models with better performance overall, or simply models that are more efficient.

Towns near Fukushima plant struggle to attract families with children

 Japan Times 27th Jan 2025

The Great East Japan Earthquake on March 11, 2011, and the subsequent meltdowns at the Fukushima No. 1 nuclear power plant have left deep scars on Fukushima Prefecture, which has seen a significant decline in its estimated population.

Futaba County, home to the Fukushima plant that straddles the towns of Futaba and Okuma, has been hit particularly hard, with the prolonged evacuation of residents drastically reducing the number of children in the area. The region’s population decline due to the disaster is beyond the scope of natural or social population shifts.

Municipalities in the region are trying to come up with measures to bring back residents or attract new ones, but increasing the number of children remains a tall order.

Futaba County once enjoyed a high birth rate and strong ties among its residents thanks to stable job opportunities provided by the Fukushima No. 1 and No. 2 power plants and related industries.

Saki Yoshizaki, 36, a worker who lives in the city of Iwaki, gave birth to her eldest daughter, now 14, in her hometown of Okuma in 2010, a year before the nuclear disaster.

“With many relatives, friends and acquaintances around, the whole community helped raise children. I had almost no worries about becoming a parent,” Yoshizaki said, recalling her hometown fondly. “In a good way, it was a tight-knit community.”

However, such an environment changed suddenly following the nuclear incident as residents fled elsewhere. Today, young parents who are bearing and rearing children in the region are voicing their feelings of loneliness where community ties have been severed.

Minami Suzuki, 34, a co-representative of the volunteer group Cotohana in the Futaba town of Tomioka, worries about the future of the region. “If we don’t strengthen connections among parents, it might become increasingly difficult for the younger generations to choose to have children here,” she says……………………………………………………………………………………..

Trump calls North Korea a ‘nuclear power,’ drawing a rebuke from Seoul

Yahoo! News, Stella Kim,  Wed, January 22, 2025 

SEOUL, South Korea — Denuclearization of North Korea is a prerequisite for global stability, South Korea said Tuesday after President Donald Trump described the reclusive regime as a “nuclear power,” raising concern that the U.S. could be moving toward recognizing the North as a nuclear-armed state.

Since Trump was last in office, North Korean leader Kim Jong Un has vowed to “exponentially” boost his nuclear arsenal and ramped up weapons testing, including of missiles that could potentially strike the continental United States and overwhelm U.S. treaty ally South Korea.

The newly inaugurated Trump, who met with Kim three times during his first term to discuss North Korea’s U.N.-sanctioned weapons programs, spoke enthusiastically Monday about his past relationship with Kim, saying they liked each other.

“Now, he is a nuclear power,” Trump said while signing a series of executive orders in the Oval Office. “I think he’ll be happy to see I’m coming back.”

Trump’s defense secretary nominee, Pete Hegseth, also called North Korea a “nuclear power” during his Senate confirmation hearing last week.

While it is unclear what Trump and Hegseth meant by “nuclear power,” U.S. officials have long refrained from using the phrase as it could signal recognition of North Korea as a nuclear-armed state.

The Trump administration did not immediately respond to a request for comment Tuesday.

Though there is growing debate as to whether the international community should accept North Korea’s nuclear status, experts say doing so would significantly disrupt the geopolitical balance in the region and potentially set off an arms race, including the possible development of nuclear weapons by South Korea and Japan………………………….  https://www.yahoo.com/news/trump-calls-north-korea-nuclear-115137317.html

North Korea beats sanctions to acquire key tool for nuclear weapons.

 North Korea obtained a key tool used in the production of nuclear warheads
by shipping it through three separate countries in an elaborate ploy to
dodge international sanctions on the country’s weapons programme.

According to a US think tank, authorities in Mexico, South Africa and China
failed to spot false documentation for a vacuum furnace, which can be used
in creating uranium fuel for nuclear warheads.

The case demonstrates the
increasing difficulties of enforcing international sanctions against North
Korea. The report by the Institute for Science and International Security
cites unnamed government sources to describe an incident in 2022, when the
vacuum furnace was shipped from Spain with an accurate declaration of its
function.
