A lonely evening at home for Fukushima man retracing past
Unsurprisingly, concerns about radiation levels are still on the minds of many former residents. His wife, Mikiko, 64, refused to accompany him for that reason. Ikeda was the only individual in his neighborhood who took up the offer to return home.
December 11, 2021
OKUMA, Fukushima Prefecture–Settling in for the night, Mitsuhide Ikeda poured sake into a glass and raised a toast to framed photos of his deceased parents: “I finally made it back home. Let’s drink together.”
The last time the 60-year-old cattle farmer spent a night at home was 10 years and nine months ago.
Large parts of this town that co-hosts the Fukushima No. 1 nuclear power plant were declared “difficult-to-return” zones after the triple meltdown triggered by the 2011 earthquake and tsunami disaster.
Ikeda’s parents died after the nuclear accident.
The Shimonogami district where the Ikeda’s home is located lies about five kilometers southwest of the Fukushima nuclear facility.
As part of efforts to rebuild the areas around the plant, the government recently began letting residents return home for an overnight stay as a means of preparing for the day when they can do so permanently.
Unsurprisingly, concerns about radiation levels are still on the minds of many former residents. His wife, Mikiko, 64, refused to accompany him for that reason. Ikeda was the only individual in his neighborhood who took up the offer to return home.
Dangerously high radiation levels registered immediately after the disaster that made it impossible for anybody to live in the area have gradually fallen. The government spent vast sums on the time-consuming process of decontaminating topsoil as a way of reducing radiation levels.
It intends to lift the evacuation order for some parts of Okuma in spring. That would be the first step for setting the stage for residents to return home.
The temporary overnight stay program began in Katsurao on Nov. 30 and is gradually being expanded to five other municipalities, including Okuma.
A check for radiation in November on the Ikeda plot found one spot with a reading of 3.8 microsieverts per hour, above the level deemed safe enough for the government to lift the evacuation order.
Even though the Environment Ministry is planning additional decontamination work, Mikiko was unsettled by the reading and concluded it would be impossible to pick up the threads of their past life in Okuma.
Other changes in the close to 11 years since the nuclear disaster make a return to Okuma unrealistic.
While a large supermarket, hospital and bank branch remain standing in the town, there is no indication when those facilities might resume operations.
In the interim, the Ikedas plan to commute to Okuma from the community they moved to as evacuees.
The overnight stay program is restricted to an area close to what was once the bustling center of the town. About 7,600 residents lived there before the nuclear disaster.
The town government envisions that as many as 2,600 people will reside in the town within five years of the evacuation order being finally lifted if plans proceed to rebuild social infrastructure.
But the writing is on the wall for many people.
According to the Environment Ministry, about 1,150 homes in the district had been torn down as of the end of September.
And as of Dec. 8, only 31 residents in 15 households applied for the overnight stays.
Even Ikeda admits that Okuma will likely never return to the community he knew before 2011.
“Too much time has passed,” he said.
China Wants to Join Southeast Asia’s Nuclear-Free Zone
A greater factor in China’s calculus is the AUKUS alliance among the U.S., U.K. and Australia. Under the security partnership announced in September, the U.S. and U.K. agreed to equip Australia with a fleet of nuclear-powered submarines to counter China’s influence in the Indo-Pacific. China wants to even the score. In a phone call with counterparts from Malaysia and Brunei that same month, Chinese Foreign Minister Wang Yi skewered AUKUS as anathema to the Bangkok Treaty. “The United States and Britain chose not to participate in the SEANWFZ [Southeast Asia Nuclear Weapon-Free-Zone] Treaty,” Wang reminded his peers. “Instead, they have transferred military nuclear technology to the region under various pretexts and also provided the region with highly enriched uranium materials, running counter to the efforts made by ASEAN countries to build a nuclear-free zone.”
China Wants to Join Southeast Asia’s Nuclear-Free Zone. Why Now? LawfareBy Ryan A. Musto Thursday, December 9, 2021 China is ready to rock with the Treaty of Bangkok.
In a rare appearance at the special online summit for the Association of Southeast Asian Nations (ASEAN) on Nov. 22, China’s President Xi Jinping announced that China is prepared to sign the protocol of a 1995 agreement that establishes Southeast Asia as a nuclear-weapon-free zone. Under the agreement, known as the Bangkok Treaty, 10 regional states renounce the right to nuclear weapons in any form within the ASEAN zone. If it joins the treaty, China would agree not to use or threaten the use of nuclear weapons within the zone or against its members. It would make China the first nuclear-weapon state to adhere.
China’s support for the treaty is no surprise. To strengthen its enduring “no-first-use” policy to never initiate nuclear conflict, China routinely has asserted (most recently in a 2019 white paper) that it “is always committed to … not using or threatening to use nuclear weapons against non-nuclear-weapon-states or nuclear-weapon-free zones unconditionally.” For the Bangkok Treaty, ASEAN and China agreed in 2011 to a secret memorandum of understanding that preserves China’s territorial claims in the South China Sea, removing the greatest hurdle to Beijing’s commitment. China was ready to sign the protocol and memorandum in 2012 but deferred once the other eligible “P-5” nuclear-weapon states under the Non-Proliferation Treaty—France, Russia, the United Kingdom and the U.S.—refused to join. Now, Xi wants to legally bind China to the treaty “as early as possible.” But what’s the rush?
Adherence to the Bangkok Treaty would burnish China’s image amid its rapid expansion in nuclear capabilities…………

Inside information from China could sink the French nuclear flagship EPR.

Inside information from China could sink the French nuclear flagship EPR https://www.ausgestrahlt.de/blog/2021/12/09/insider-infos-aus-china-k%C3%B6nnen-franz%C3%B6sisches-atomflaggschiff-epr-versenken/ 09.12.2021 | Eva Stegen In 1989, in response to Chernobyl, development of a third generation reactor began. The European pressurized water reactor EPR has not yet generated a kilowatt hour in Europe. Despite multiple disasters, no one pulled the rip cord. Now a whistleblower reveals a system error that should be the end of the EPR.
Some people either have nerves of wire, no self-esteem or the deep certainty that any nonsense they utter will be whipped into all media via the international press agencies, just as if one did not have to check a completely absurd announcement at least once. But it is so, the French emperor is naked. He just yelled out to the press that he wanted to have six more reactor construction sites for the fiasco flagship EPR (European pressurized water reactor) when a whistleblower tore the last scrap of material off his body. It was a French nuclear engineer who had an in-depth look at the EPR reactors in Taishan, China. They are the only two – out of 200 announced – that ever went online.
There it was just ………
However, one of the two is offline again after just 2.5 years of operation. With an unknown outcome. Evidence is growing that a design flaw affecting the entire EPR series has led to Taishan 1 being switched off. The whistleblower gave the radiation research institute ‘CRIIRAD’ important detailed technical information from Taishan. CRIIRAD, in turn, put a series of questions to the French nuclear regulator, ‘Autorité de Sûreté Nucléaire’, ASN.
The silence of those who knew it
A copy was sent to the news agency ‘AFP’, but miraculously the horror news did not spread as rapidly as Macron’s ludicrous announcement to sink further billions in further ‘EPR’ flop construction sites. With every additional day on which neither the operator nor the nuclear regulatory authority deny ‘ASN’, this hypothesis of the design flaw, which affects all ‘EPR’, becomes more important.
In June 2021, a CNN report from Taishan, China caused a stir. There was talk of an “imminent radiological threat” in a letter from the French consortium partner “Framatome” to the US Department of Energy, which “CNN” has received. The Chinese security authorities were accused of having raised the radiation limit values for the outside area around the nuclear power plant in order to circumvent the shutdown of the defective reactor block.
Where do the radioactive gases come from?
As early as October 2020, defects were found on the cladding tubes of some fuel elements, which led to the escape of radioactive gases in the reactor pressure vessel. Despite the radiological risks for workers and residents, the nuclear power plant continued to operate. First of all, according to Bruno Chareyron from ‘CRIIRAD’. This duct damage is quite normal, something like that happens. In fact, however, the degree of damage to the cladding tubes and the gas leaks in the reactor have steadily worsened since it was loaded with fuel in autumn 2020.
The operators have asked the authorities to increase the limit value, above which the reactor must be shut down. The authorities would have doubled the value , but as the contamination continued to rise, the new warning threshold was exceeded at the end of May 2021. This continued until the shutdown on July 30, 2021. In August, the fuel rods began unloading. Nobody knows when or whether the reactor can ever start again.
Thanks to the whistleblower’s insider knowledge, ‘CRIIRAD’ is now able to track down the causes of the defective ducts, which the investigative satirical magazine ‘le Canard enchaîné’ described as “knots in the pipelines”. The cameras that the Chinese had brought into the heart of the EPR, in the reactor pressure vessel, were supposed to check the thesis that the zirconium cladding tubes that protect the uranium fuel rods are unusually corroded.

The cameras that the Chinese had brought into the heart of the EPR, in the reactor pressure vessel, were supposed to check the thesis that the zirconium cladding tubes that protect the uranium fuel rods are unusually corroded.
In addition to the risk of pipe rupture in the primary circuit, there is also the risk that the grids, which are intended to hold the fuel elements in position in the reactor pressure vessel, are damaged by the vibrations. If this structure is weakened , Chareyron explained , it is conceivable that in the event of an earthquake the clusters of fuel and control rods would swing against the inner walls of the container. A deformation induced in this way could mean that the control rods, which are actually supposed to brake the nuclear chain reaction, cannot retract.
Bad Vibrations from Olkiluoto and the scandal forge Le Creusot
As early as 2018, the Finnish electricity supplier ‘TVO’ and the Finnish safety authority ‘STUK’ reported that during tests on the Olkiluoto EPR permanent construction site, vibrations had occurred in the primary circuit on the reactor pressure vessel .
But as early as 2007/08 hydraulic model tests at the scandal-shrouded nuclear component manufacturer in Le Creusot brought the vibration problem to light. That is why ‘CRIIRAD’ asks the nuclear supervisory authority about the failed attempt to reduce the flow of water with the help of a baffle that was attached under the reactor core in order to influence the hydraulics and thus the vibrations. The vibration problem is obviously inherent in the system and affects not only the Taishan blocks but also Olkiluoto, Flamanville and Hinkley Point C. In short, all Generation 3 reactors that were once touted as “inherently safe”.
Corecatcher not catchy
In addition to carbon-brittle forging errors, messed up welds and inferior concrete, there are also vibrations of the artfully knotted pipeline design. The once-praised core catcher, which was supposed to catch a melted reactor core, apparently also gives the engineers a headache. If a large fragment of the container were to block the slide to the catcher, the corium would not flow into the catcher, according to the confidential account. But the naked Emperor Macron never tires of loudly proclaiming his atomic illusions. If the idea of the third generation of EPR reactors, which incidentally dates back to 1989, doesn’t work, you can tell the same nonsense again. Simply use the same “climate saver” texts again, just replace generation 3 and EPR with generation 4 and SMR. Apparently, the president is sure that the news agencies and the associated copy-paste editorial offices are already creating the appropriate mental cinema for EU citizens. Because he wants taxonomy money from them, for even more atomic illusions.
Turkey’s nuclear plans threaten Eastern Mediterranean ecosystems
Turkey’s nuclear plans threaten East Med ecosystems, ekathimerini.com, Elias G. Hadjikoumis, 10 Dec 21, Turkey has had plans to establish nuclear power plants since the 1970s, and these plans have become a key aspect of the country’s goal of economic development and growth. The Akkuyu Nuclear Power Plant (ANPP) is the first. Turkey and Russia ratified the agreement to construct the plant in May 2010. The agreement indicated that Akkuyu NGS Elektrik Uretim Corp, a subsidiary of Rosatom, would construct, own and operate the plant. The nuclear power plant is to comprise four reactors. While the major construction activities began in March 2018, the first reactor unit is expected to be operational in 2023 and the remaining units in 2026. Once complete, the plant is seen covering 10% of the country’s total electricity supply. Turkey also intends to build two nuclear power plants on the Black Sea coast to meet energy demands. Although the plants would give the country clean [?] energy and make it energy-independent, there are numerous negative environmental effects associated with the generation of nuclear energy, and these pose a threat to Turkey’s neighboring countries as well as Turkey itself.
Nuclear is considered a clean source of energy because no carbon dioxide is emitted during operation, however, all activities related to building and running a plant lead to the production of high amounts of CO2, including the current construction and plant development processes at Akkuyu. Additionally, the plant will use uranium as its main source of fuel, whose extraction processes release great amounts of CO2 into the atmosphere.
The power plant is located close to the Eastern Mediterranean, a region which comprises a vast set of coastal and marine ecosystems that deliver valuable benefits to all its coastal inhabitants. The region is set to experience negative environmental changes because of the huge amounts of water that will be required to cool the plant’s reactors. Pumping the seawater used to cool the four reactors back into the sea could lead to an 80% increase in water temperatures (2 to 5 degrees Celsius). The temperature rise would affect the area’s marine diversity. Environmentalists expect a decline in the number of fish because the high temperatures would probably kill most of them and reduce the egg-laying capacity of the rest. The high temperatures will also make the marine environment uninhabitable for a colony of Mediterranean monk seals and a very rare species of sea daffodil (Pancratium maritimum).
ANPP will affect countries around Turkey, especially Cyprus and Greece. Greece has already raised the alarm due to the lack of significant evaluation of the project and any protective measures for the environment and its neighbors. In fact, there were claims that the evaluation process for the plant was never concluded in Turkey. It is said that the government was influenced to hasten and conclude the evaluation process to favor its establishment in the specified site, which many consider unsafe because of the seismic activity in the area.
The European Parliament has called on the Turkish government to halt construction of the plant, citing the location of the construction site in a region prone to severe earthquakes. According to the European Parliament, the location of the site in a region prone to earthquakes poses a threat to Turkey and the entire Mediterranean region. The facility is situated 16 miles from the Ecemis fault line at the meeting point of the Eurasian and African tectonic plates. The fault was initially believed to be inactive when the nuclear plant’s site license was issued in 1976. However, scientific studies published in recent decades have shown that the fault is active. A nuclear engineering professor from an Istanbul university, one of the original nuclear engineers who signed the site license in 1976, indicates that the current construction is based on ignorant planning
and may pose a considerable threat to the Mediterranean region……………..
So far, no consultations have been held with neighboring countries. Commenting on the issue, a representative of the European Commission indicated that Turkey was not a party to international conventions, requiring countries to consult their neighbors over the environmental effects of major projects. The EU representative emphasized that Turkey is expected to align its legislation with EU requirements on such projects………
the greatest concern in the development of ANPP is radioactive waste in the East Medn region. Turkey has not yet signed the Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management which came into effect in June 2001. Burying radioactive waste in the region would make it uninhabitable and in the event of an accident, the radioactive leak would be catastrophic to the environment. Local observers have already raised these issues. The observers argue that there has not been any clear explanation as to how Rosatom will dispose of the radioactive byproduct material generated by the nuclear plant. They fear that the site may even become a Russian nuclear dumpsite.
In conclusion, the nuclear project is a threat to Turkey and its neighbors. Its location in earthquake-prone areas and its anticipated negative environmental impact mean that the international community should put it on hold until a further assessment is carried out to determine its environmental viability. The project should be placed on hold because Turkey is not a signatory of international conventions and hence not obliged to consult with neighboring nations. The lack of consultations means that Turkey does not adequately account for the negative externalities arising from the plant on neighboring countries such as Greece and Cyprus.
Further assessment is needed to determine the effect of the plant on marine life and the potential negative effects owing to the vulnerability of Turkey and the Mediterranean region to earthquakes. The project was initiated and started even before a full commission and evaluation had been done and Turkey’s energy policies and prospects have a short overview, increasing the likelihood of an accident or lack of appropriate measures to contain any accidents in the region. The international community should take a strict position vis-a-vis the project, asking for close and consistent monitoring of all the nuclear development activities and future operations of the plant. https://www.ekathimerini.com/opinion/1173463/turkey-s-nuclear-plans-threaten-east-med-ecosystems/
Taishan Problems An investigation is still under way into leaks at nuclear power plant.
nuClear News No 136 Dec 21, Taishan Problems An investigation is still under way into the cause of problems at the Chinese EPR plant in Taishan. It was shut down in August after reports of damage to fuel rods. The plant is operated by CGN and owned in partnership with EDF, the two companies involved in building Hinkley Point C (HPC).
The Times (1) has reported that key safety components at HPC may need to be redesigned and the project delayed after defects were detected at a similar reactor in China. The newspaper says the scheduled start date for electricity generation, of June 2026, may have to be postponed.
The Commission for Independent Research and Information on Radioactivity (CRIIRAD), a French association created in the aftermath of the Chernobyl disaster, said that a whistleblower had reported to them that a design flaw in the reactor pressure vessel could be the cause of the problem at Taishan which means that design changes may be needed.
In a letter to the French nuclear regulator (2), ASN, CRIIRAD says: “In June 2021, the national and international press widely covered the case of the problems of ruptured nuclear fuel cladding at the Taishan 1 EPR reactor in China.”
It goes on to say there are several possible causes of the rupture some of which may involve design flaws in the reactor. A whistleblower has now told CRIIRAD that the ruptures are caused by a design flaw in the reactors pressure vessel. This will also cause problems in other EPR reactors like Hinkley Point C.
The letter continues: “If they are true, these revelations raise serious questions in terms of nuclear safety and radiation protection, both for plant workers and for residents. The existence of a generic design defect on the EPR reactor vessel could jeopardize the start-up of [other EPR reactors].”
Stop Hinkley spokesperson, Roy Pumfrey says:
“What’s been cobbled together to get Taishan started clearly isn’t working. It’s just another example of the folly of complex designs for big new nuclear reactors. Trying to identify and correct the design flaw can only lead to further delays and cost overruns for the absurdly expensive HPC project.”
“Stop Hinkley will be pressing the UK’s Office of Nuclear Regulation for a full disclosure of its investigations into this matter. And if there are expensive delays and modifications to HPC required, given the already huge cost to consumers, we will be asking government officials to investigate whether, in fact, it would be cheaper to cancel the whole thing.”
Eva Stegen, German blogger and energy consultant says the whistleblower gave the radiation research institute ‘CRIIRAD’ important detailed technical information from Taishan. With every additional day on which neither the operator nor the French nuclear regulatory authority – ASN – deny, the hypothesis that the design error affects all EPRs, Taishan’s problems become more important. She reminds us that in June 2021, a ‘CNN’ report from Taishan, China caused a stir. There was talk of an “immediate radiological threat” in a letter from the French consortium partner “Framatome” to the US Department of Energy. The Chinese security authorities were accused of having raised the radiation limit values for the outside area around the nuclear power plant in order to circumvent the shutdown of the defective reactor block.
In this context, a little-noticed communication of the Institute for Radiation Protection and Nuclear Safety – IRSN – of March 31 assumes new significance: the Institute expressed concern about “abnormally high vibrations” already observed in the primary circuit of several EPR reactors. It said the overall architecture of the primary circuit piping leads to the severe vibrations in the reactor pressure vessel due to an unfavourable distribution of the cooling water. These vibrations could lead to a pipe rupture in the primary circuit and cause significant radioactive releases. This raises the question whether the entire piping architecture should not be revised
As early as 2018, the Finnish power utility ‘TVO’ and the Finnish safety authority ‘STUK’ reported that during tests at Olkiluoto, vibrations had occurred in the primary circuit at the reactor pressure vessel.
So along with carbon-brittle misfits, botched welds and inferior concrete comes the vibration problem. The once-vaunted core catcher, which was supposed to be used to contain a melted reactor core, is apparently also giving engineers a headache. If a major fragment of the vessel were to block the chute to the catcher, the corium would not flow into the catcher.

Taiwanese Group walks for 30 hours to protest nuclear power
SYMBOLIC MARCH: The demonstrators represented the number of boroughs that would be evacuated if there were a disaster at the Fourth Nuclear Power Plant
- By Yang Mian-chieh / Staff reporter, with CNA A group of 21 people demonstrating against nuclear power completed their march in Taipei yesterday after beginning it in New Taipei City’s Gongliao District (貢寮) the day before.
They were joined by supporters as they reached their destination on Ketagalan Boulevard in front of the Presidential Office Building after nearly 30 hours of walking.
Organized by the National Nuclear Abolition Action Platform, the event was aimed at encouraging people to vote “no” in a referendum on Dec. 18 that asks whether the government should restart construction on the mothballed Fourth Nuclear Power Plant in Gongliao District.
The 21 demonstrators represented the 21 boroughs within an 8km radius of the power plant that would be required to evacuate in the event of a nuclear disaster: 11 boroughs in Gongliao District, eight in New Taipei City’s Shuangsi District (雙溪) and two in Yilan County’s Toucheng Township (頭城), the National Nuclear Abolition Action Platform said.
Separately yesterday, a group rallied in front of the Legislative Yuan in Taipei, urging people to vote “yes” for the referendum question on whether a liquefied natural gas (LNG) terminal project should be relocated to protect algal reefs off Taoyuan’s Guanyin District (觀音).
They called for the government to review the nation’s energy policy rather than resort to “emotionally blackmailing the public with fears of a power shortage.”
Environmentalists have said that the algal reef took at least 5,000 years to form and is the largest of its kind in the world.
It also has rich biodiversity, and is home to the endangered coral species Polycyathus chaishanensis and hammerhead sharks that are listed on the International Union for Conservation of Nature Red List of Threatened Species, they said…….

Safety fault in China’s European Pressurised Water Reactor (EPR) does not bode well for UK’s Hinkley Point C and Sizewell nuclear projects
Key safety components in the UK’s first new nuclear power station for 30 years may need to be redesigned and the project could be delayed after defects were detected at a similar reactor in China.
The £22 billion Hinkley Point C plant in Somerset is already well over budget and a decade late but the defects mean that the scheduled date for starting electricity generation, of June 2026, may have to be revised. The same power plant design is due to be used for another nuclear power station, Sizewell C in
Suffolk, which is planned but has not yet been approved.
An investigation is still under way into the cause of the problems with the plant in Taishan, in the southern Chinese province of Guangdong. It was shut down in August after reports of damage to fuel rods, which hold nuclear materials used to fuel the reactor.
The plant is operated by China General Nuclear Power Group and owned in partnership with the French state-controlled EDF, the two companies involved in building Hinkley Point C.
The Commission for Independent Research and Information on Radioactivity, a French association
created in the aftermath of the Chernobyl disaster, said that a whistleblower had reported that a design flaw in the reactor pressure vessel could be the cause of the problem at Taishan. An industry source
told The Times that the investigation was likely to show that the pressure vessel was “demonstrably safe” but it might also show that design changes were needed.
Paul Dorfman, a nuclear expert at the University of Sussex, said: “If the news we are hearing from the Taishan EPR [European pressurised reactor] is right, then it’s beginning to look like there’s a potential generic fault with the key safety mechanism of the EPR reactor design itself. “If so, this is serious news for ongoing construction at Hinkley Point C and plans for Sizewell C.

Whistleblower explained the tank design problem that caused the shutdown at Taishan nuclear power station
Last July, in China, the Taishan nuclear power plant was shut down. A few weeks earlier, an incident had taken place in the only EPR plant in service in the world, designed jointly by the Chinese CGN and the French EDF.
At the end of November, perhaps finally an explanation: the incident was due to a fault in the design of the vessel, according to a major French association specializing in nuclear safety. The incident which led in July to the shutdown of a reactor at the EPR nuclear power plant in Taishan, in southern China, is believed to be due to a design flaw in the vessel, the French association CRIIRAD said on Saturday.
The Commission for Independent Research and Information on Radioactivity (CRIIRAD) would get its
information from a “whistleblower”. “This is a Frenchman who works in the nuclear industry, having access to very precise technical information on the situation of the Taishan 1 reactor core,” a CRIIRAD official told AFP.
Taishan is the only pressurized water reactor (EPR) plant in the world, with two reactors. Four other EPR reactors are under construction, all in Europe: one in Finland, one in France in Flamandville and two in England. It is a tank design problem that would be the cause of the incident in Taishan reported on June 14, 2021. This is a first explanation.

Renewable energy growing at a fast pace, China and India leading the way.
Growth in renewable energy is set to hit an all-time record this year, but is still falling “well short” of what is necessary to slash planet-warming emissions, according to the International Energy Agency. The energy watchdog estimates that around 290 gigawatts (GW) of renewable energy capacity came online around the world in 2021 — enough electricity for approximately 200 million average US homes — according to a report published Wednesday.
By 2026, the agency predicts global renewable capacity will rise more than 60% from 2020 levels, an amount equivalent to the current total global power capacity of fossil fuels and nuclear combined, it said.
But to reach net-zero emissions by 2050, a goal many nations have set, renewables need a far bigger push. The current pace is being driven by China, which the agency says remains the global leader in renewable energy growth. The country is expected to reach 1200 GW of total wind and solar
capacity in 2026, four years sooner than its target date. Renewables are also being rapidly embraced in India, where they are projected to double new installations this year, in comparison to 2015-2020.

Design flaw: the incident that shut down China’s EPR nuclear station could happen to other EPR reactors.
| The type of incident that caused a reactor shutdown at Taishan plant could happen to other plants. The incident in the Chinese reactor last June is believed to be due to a design flaw in the reactor vessel. The incident which led in July to the shutdown of a reactor at the EPR nuclear power plant in Taishan (China) is believed to be due to a fault in the design of the vessel, the Independent Research and Information Commission said on Saturday (November 27th) on radioactivity (CRIIRAD) which warns against the risk of an identical problem on other EPRs.

if tomorrow Australia has some nuclear-powered submarines, why not, some other countries could ask for similar technology, it could be Indonesia, why not?’
Australia needs an entente cordiale with Indonesia over nuclear propulsion and non-proliferation, The Strategist, 29 Nov 2021, |David Engel However relaxed and comfortable Indonesian Defence Minister Prabowo Subianto might be about Australia’s plans to acquire nuclear-powered submarines (SSNs), the visit to Jakarta of French Foreign Minister Jean-Yves Le Drian has probably validated the very different view of Le Drian’s counterpart, Retno Marsudi.
……………………………………………. the most striking moment of the visit came during Le Drian’s address to Indonesia’s leading international affairs think tank, the Centre for Strategic and International Studies (CSIS). While his speech focused on issues such as multilateralism and the EU’s position on the Indo-Pacific, his response to a question on ‘minilateralism’—specifically, AUKUS and the Quad—took on a very different tone.
Ignoring the Quad, he levelled his remarks at AUKUS, stressing four points. The first two reiterated the theme of ‘betrayal’ in terms of both being ‘cheated’ out of a deal and being deceived by NATO allies and, in Australia’s case, a historical ally. He talked about American efforts to restore trust through various US commitments to France. He didn’t mention Australia in this context.
More significantly, his third point was that AUKUS was about ‘pressing a sense of confrontation with China’ (as the simultaneous translation put it). He said that, while France was not oblivious to China’s military threats and risks, he believed that the best way to respond to these threats was to ‘develop an alternative model rather than to first of all oppose’.
Perhaps his most significant point for Australian interests was his fourth, which went to the transfer of nuclear technology for submarine propulsion. He pointed out that until now no nuclear-weapon state had done this. But ‘if tomorrow Australia has some nuclear-powered submarines, why not, some other countries could ask for similar technology, it could be Indonesia, why not?’ He continued that, even though this technology was not covered by the Nuclear Non-Proliferation Treaty (NPT), the risk the arrangement posed of starting a trend was nonetheless of concern.
Irrespective of Le Drian’s intentions in answering the question in this manner—and it’s noteworthy that he didn’t cover AUKUS in his formal address—he would surely have known that his words would resonate powerfully with his audience, both at CSIS and more generally among Indonesia’s foreign policy establishment. While his depiction of Australia as duplicitous was evidently personal and heartfelt, it would also have struck a chord with those Indonesians who have characterised Canberra the same way over such issues as East Timor, Papua and spying allegations, irrespective of how justified that judgement might be.
Le Drian’s last point went directly to concerns about nuclear proliferation—issues that Indonesia highlighted in its official statement on AUKUS and the planned submarines. It corresponds closely ‘in spirit’ with subsequent official commentary to the effect that Indonesia was considering advocating a change to the NPT aimed at preventing non-nuclear-weapon states from acquiring SSNs………
whoever governs in Canberra now and into the future should at least make a priority of assuaging Jakarta’s worries on this subject, however overstated and unbalanced they are. While Indonesia’s prospects of changing the NPT and precluding Australia from having SSNs look remote at best—not least because several of its ASEAN colleagues do not share its views of Australia’s ambitions—the sooner the two countries can put this latest irritant to rest the better.
In the circumstances, the onus for doing so must primarily rest with Canberra………https://www.aspistrategist.org.au/australia-needs-an-entente-cordiale-with-indonesia-over-nuclear-propulsion-and-non-proliferation/
China puts forward proposals as Iran nuclear talks resume
China puts forward four proposals as Iran nuclear talks resumeCGTN China welcomes the resumption of talks about the Iran nuclear deal and has made four proposals in the hope of pushing forward the negotiation process, Chinese Foreign Ministry spokesperson Wang Wenbin told reporters on Monday…….
Reiterating China’s support for a diplomatic settlement, Wang put forward four proposals.
First, the U.S. is the initiator of the Iran nuclear crisis, Wang said, urging the U.S. to lift sanctions against Iran and third-party entities and individuals. On this basis, Iran should fully resume its nuclear commitments. Neither party should impose any other conditions for this, Wang said.
Second, all parties should respect each other’s legitimate rights and concerns, Wang said, calling on relevant parties to uphold the principle of mutual respect and win-win cooperation so as to promote regional peace and stability.
| The legitimate rights and interests of parties involved in economic and trade cooperation with Iran should be respected, added Wang.Third, the spokesperson called for a pragmatic and flexible negotiation strategy and encouraged all parties to use their political wisdom and settle the issue through equal consultation.China supports pushing forward the negotiation based on the previous consensuses, he noted.Fourth, Wang stressed that all parties should stay committed to a political settlement of the issue, and stay restrained and rational to maintain the negotiation process……. https://news.cgtn.com/news/2021-11-29/China-puts-forward-four-proposals-as-Iran-nuclear-talks-resume-15ADhfujpqE/index.html |
Tepco to repair Fukushima nuclear station’s partially melted protective ice wall.
Ice Wall to Halt Groundwater Flow at Japan’s Fukushima Nuclear Plant to Be Repaired https://thewire.in/world/ice-wall-to-halt-groundwater-flow-at-japans-fukushima-nuclear-plant-to-be-repaired
Tokyo Electric Power Co (Tepco) will launch remedial works at the stricken plant after ice wall tests indicated partial melting. Tokyo: Tokyo Electric Power Co (Tepco) will launch remedial works at the stricken Fukushima Daiichi nuclear plant to strengthen an ice wall intended to halt the flow of groundwater after testing indicated partial melting.
The work could begin as early as the start of December, according to a presentation from the plant operator dated Thursday, part of a costly and troubled effort to secure the site following the 2011 earthquake and tsunami.
The ice wall is intended to limit the seepage of groundwater into the plant, which has created large amounts of toxic water being stored by Tepco in tanks.
Japan plans to release more than 1 million tonnes of water into the sea after treating it. The water contains the radioactive isotope tritium, which cannot be removed.
