The US and China Could Soon Be In Race For Nuclear-Powered Satellites.

The US and China Could Soon Be In Race For Nuclear-Powered Satellites, Defense One, 16 Jan 22,

An idea from the 1960s has found new backers.,  If future U.S. satellites are to dodge incoming Russian or Chinese fire, they’ll need better ways to move around than today’s fuel-intensive thrusters. That’s why the Pentagon is looking into nuclear-powered propulsion.

While leaders at the Space Force and the Pentagon Research and Development office remain publicly quiet about the idea of putting nuclear-powered spacecraft in orbit, the Mitchell Institute for Aerospace studies released a new report that argues for more focused work on it. 

It isn’t a new concept. NASA and the Atomic Energy Commission were working toward a flight test for their nuclear rocket until the Vietnam War sapped the program’s funding. It was cancelled in 1973, and safety concerns have since scuttled further efforts………….

But one DARPA official, at least, suggests looking at the idea afresh. A 2020 policy change from the Trump White House has clearing the way for new research into nuclear propulsion, Micheal Leahy, the director of the tactical technology office at DARPA, told a virtual audience on Friday. Leahy’s office runs the DARPA Demonstration Rocket for Agile Cislunar Operations, or DRACO, program. Last April, DARPA awarded General Atomics a contract for a preliminary design of a reactor and propulsion subsystem, and gave Lockheed Martin and Blue Origin a contract for a spacecraft design.

But the bigger factor is thatChina is working along similar lines with planes to field its own nuclear-powered satellites by 2040. The lessons from the current gap in hypersonic missile technology should provide a cautionary tale, Leahy said. 

“We had the lead in hypersonics, only to watch it go away. Right?… Now I’m in a tail chase,” he said.  https://www.defenseone.com/technology/2022/01/us-and-china-could-soon-be-race-nuclear-powered-satellites/360792/

China opposes Japanese decision to release nuclear-contaminated water into ocean

 BEIJING, Dec. 22 (Xinhua) — China is seriously concerned about and firmly opposes Japan’s unilateral decision to discharge the nuclear-contaminated water into the sea and its proceeding with the preparatory work, a Chinese Foreign Ministry spokesperson said Wednesday.

Zhao Lijian made the remarks when asked to comment on a media report that Tokyo Electric Power Company has submitted an application to Japan’s Nuclear Regulation Authority with a detailed plan of discharging nuclear-contaminated water from the Fukushima Daiichi nuclear power plant into the sea.

Since April this year, the international community has raised concerns to the Japanese side over the legitimacy of the discharge into the sea, the rationality of the discharge plan, the credibility of the data about the nuclear contaminated water and the reliability of the equipment to purify the nuclear-contaminated water, Zhao said.

The work of the IAEA technical working group on the handling of the nuclear-contaminated water from Fukushima is still undergoing, he added.

“In total disregard of the legitimate and reasonable concerns of the international community, the Japanese side only continues to proceed with the preparations for the discharge both policy-wise and technology-wise,” Zhao said.

“Obviously, it wants to impose its wrong decision on the entire international community, and it is all the littoral countries of the Pacific Ocean that will have to take the risk for such move. The Japanese side is extremely irresponsible in doing so.”……….. http://www.xinhuanet.com/english/asiapacific/20211015/C9A4AEDD72B00001F26810B030601260/c.html

Safety Concerns Mount Over Damaged Fuel Rods at China’s Taishan Nuclear Plant

The second EPR reactor at China’s Taishan nuclear power plant is about to enter into commercial operation.

Safety Concerns Mount Over Damaged Fuel Rods at China’s Taishan Nuclear Plant
A French whistleblower claims that the real number of damaged fuel rods exceeds the figure acknowledged by officials, and that there may be issues with other reactors of the same design.  By Jesse Turland  The Diplomat December 11, 2021
 On November 28 Radio France International Chinese published claims by a whistleblower contradicting official statements downplaying the extent of damage to fuel rods at the Taishan 1 Nuclear Reactor in Taishan, Guangdong province.

The whistleblower, who works at a French nuclear energy company, warned that more than 70 fuel rods were damaged, 14 times the figure acknowledged by China’s Ministry of Ecology and Environment (MEE) in June, when it stated “about five” rods were damaged. Additionally, the whistleblower claimed the damage may be linked to a “design flaw.”

Under pressure from public activism, France’s nuclear energy regulator, Autorité de sûreté nucléaire (ASN), yesterday announced it would halt the development of the EPR reactor at Flamanville in Normandy, which uses the same design as Taishan, pending inquiries into the malfunctions at Taishan.

There is still a lot of work to be done on the [Flamanville] site before start-up operations, and feedback from the experience of the Taishan 1 EPR deviation must take place,” said ASN deputy general manager Julien Collet yesterday.

Located 110 kilometers south of Guangzhou, Taishan is the site of the world’s first reactors of the Evolutionary Power Reactor (EPR) design to commence operation. Its two reactors are capable of generating 1,750 Megawatts electric (Mwe) each.

According to the whistleblower, the problem of the Taishan EPR reactor is “a not-very-successful hydraulic system at the bottom of the vessel which gives an uneven distribution of power in the assemblies. A transverse current is created in the core and causes the assemblies to move, especially those at the periphery.”

The whistleblower’s claims were relayed by Bruno Chareyron, director of the Commission for Independent Research and Information about Radiation (CRIIRAD), a Paris-based NGO established in 1986 to monitor radioactive leaks in the wake of the Chernobyl disaster.

The whistleblower’s claims were relayed by Bruno Chareyron, director of the Commission for Independent Research and Information about Radiation (CRIIRAD), a Paris-based NGO established in 1986 to monitor radioactive leaks in the wake of the Chernobyl disaster.

There are at least three consequences. One is the fact that due to the damage to the nuclear fuel, a significant amount of radioactive substances migrate across the cladding of the rods and is go into the water of the primary circuit,” according to Chareyron.

“So radioactive gases like krypton and xenon are accumulating in the water inside the pressure vessel… Those gases are collected into tanks and those tanks are opened to the atmosphere normally every two months. But with fuel rod damage, some of the gases released have half-lives of years, like Krypton 85.”

He continued: “[The] second problem is the impact on the people working in the plant. Because if you have such damage in the core of the reactor, you contaminate the water inside the pressure vessel, but some of this contamination will stay inside the tubes, the pipes, the pumps.

“So when the operators have to conduct maintenance, they receive much more radiation than if the cladding fitted properly.”

Finally, “The third problem is if the fuel assemblies are a little bit broken, it means that you may reach a situation when, for example, in case of an earthquake, you cannot insert the control rods into the fuel assemblies because the assemblies are damaged,” Chareyron 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.

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.

Taishan Problems An investigation is still under way into leaks at nuclear power plant.

The second EPR reactor at China’s Taishan nuclear power plant is about to enter into commercial operation.

  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.

Safety fault in China’s European Pressurised Water Reactor (EPR) does not bode well for UK’s Hinkley Point C and Sizewell nuclear projects

The second EPR reactor at China’s Taishan nuclear power plant is about to enter into commercial operation.

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.

An association created in the aftermath of the Chernobyl disaster, CRIIRAD wrote on Saturday to the management of the Nuclear Safety Authority (ASN) to share this information with it, which it says it has from a “whistleblower”. “This is a French person who works in the nuclear industry, having access to very precise technical information on the situation of the Taishan 1 reactor core,” said
Bruno Chareyron, director of the CRIIRAD laboratory.
