Push for Small Nuclear Reactors Runs Into Regulators’ Old Rules
Feb. 7, 2022, 8:00 PM

The nuclear power industry is betting its future on a new generation of reactors small enough to fit on a truck—an emerging technology that mostly uses alternatives to water for cooling, runs at lower pressure than traditional units, and costs far less than the behemoth power plants and cooling towers that define the nuclear landscape today.
But advocates of the idea insist that the folks in Washington who police their business have no idea how to assess it. Today’s rules are “really a square peg in a round hole for these advanced reactor designs,” says Amy Roma, a partner with the law firm Hogan Lovells who’s worked on dozens of license applications. The Nuclear Regulatory Commission, she says, is “largely divorced of actually understanding—in depth—the technology.”
Congress has ordered the NRC to write rules to replace a regulatory framework that dates to the 1950s. The new guidelines aren’t expected until at least 2025, so for now the agency is operating as it has for decades, evaluating plants that bear scant resemblance to those the regulations were meant to assess. To prove the safety of designs, for instance, the commission demands data from similar plants, but none of the smaller installations have been built in the U.S., so there’s no performance history. And the rules are geared toward so-called light-water reactors, which split uranium atoms to create steam that drives turbines. The newer technology typically uses substances such as molten salt and lead, or gases like helium, to keep the core from overheating. No company employing these technologies has won a construction license, and only one design—a water-cooled model from NuScale Power LLC—has been approved. The NRC declined to make any commissioners or staffers available for an interview on the subject.

Hydrogen and Ammonia production will be much easier using Small Modular Nuclear reactors!​

Core Power MSR to Produce Ammonia Fuel for Ships


Posted on February 2, 2022 by djysrv


green ships
A UK based firm Core Power is working on a concept for an offshore facility that combines advanced nuclear power (molten salt reactor) with an offshore ammonia production facility, which would enable affordable production of green ammonia for shipping.
In a report titled “The New Alchemy” it promotes the business case for production of ammonia as a green fuel for international shipping which could be produced in floating nuclear power plants. A Q&A below has additional details.
Core Power says that its modeling showed that with current technology it is possible to produce one million tonnes of ammonia per year using 1.2 GW of electric power, on each nuclear powered floating production platform, reducing to 0.9 GW by 2050.
This is the equivalent of 440,000 tonnes of very low sulphur fuel oil (VLFSO), and it would allow the decarbonization of a considerable number of ocean going cargo vessels.

West Virginia Lifts Decades-Long Ban on New Nuclear Builds​



Washington, D.C.—The following statement can be attributed to Maria Korsnick, president and chief executive officer of NEI:
“NEI applauds the West Virginia legislature for lifting a decades-long ban on nuclear carbon-free power plants in the state. The forward-thinking decision is part of a national trend to recognize the role of reliable, carbon-free nuclear power in our energy transition. Removing antiquated policies like moratoriums on nuclear plant construction serves as a steppingstone toward a decarbonized future and ensures a reliable and cost-effective energy transition that creates good-paying, long-term jobs.
With more fossil fuel plants retiring, new nuclear technologies are more essential than ever to preserve jobs and provide a supply of always-on carbon-free power. The passage of this bill alongside the state’s recent resolution on grid stability opens the door for advanced nuclear to be the backbone of the energy grid for West Virginia.”

I believe that all of these retiring coal fired power plants would be ideal candidates for SMR's the infrastructure is all there already.

I can see this happening here in Oz one day?

Wind and Solar are good, but the sun doesn't always shine and the wind doesn't always blow, battery storage is way to dear for a reliable back up, the world needs base load power that is clean and nuclear (especially SMR's) fits that bill perfectly.

Yes BRN is the story today for sure, but SILEX will be a contender for them shortly IMHO.
They have some great technology that can be used in multiple platforms, much the same goes for Polynovo (PNV) David Williams (from Kitter Williams fame) says PNV will be a $10 billion company in the near future, I reckon Silex will also be one and may even do better than PNV.

Both of these companies have had a lot of shorting recently, they will have to cover at some point, the trolls have been furiously working for them over on hotcrapper.

This was posted by Toby 10 on the other site, it seems to confirm what I have been saying for some time,and also what Cameco have previously said about being the "go supplier of enriched Uranium for North America", and it sits well with what PAC Partners said about Silex paying a dividend in 2025/26? see attached file,

Keep in mind that PAC partners were hired by SILEX to help them with communications to shareholders, so I do think they would have a much better idea about what is to happen than the average punter,
A lot of discussion has happened on HC about when Cameco would buy their other 24% of GLE, the consensus was when either the commercial plant was either proven or when the first plant was started (PLEF)?
Another thing! Why would Cameco be the LEAD for GLE when it has only 49% at the moment, SLX would normally be the lead on this under with their 51% ownership at this time surely?


Interesting times ahead "I believe."

Here is what Toby posted.

"Clean-energy innovation: In 2021, we increased our interest in Global Laser Enrichment LLC (GLE) from 24% to 49% and signed a number of non-binding arrangements to explore several areas of cooperation to advance the commercialization and deployment of small modular reactors (SMRs) in Canada and around the world. This furthers our commitment to responsibly and sustainably manage our business and increase our contributions to global climate change solutions by exploring other emerging and non-traditional opportunities within the fuel cycle."

I know this is the SLX thread but the same might apply!

I found this on the other site, it was posted by Bedger (thanks)-: " If PNV investors en masse told their brokers not to lend their stock for shorting, it would create a short squeeze as custodians would not be able to borrow stock to cover the risk and force their clients to buy back short positions."
I have notified my brokers that I in no way want my shares lent for shorting purposes, maybe others should do the same, if they don't want their shares lent for shorting purposes!

I was told by both Comsec and Westpac that they do not do this, but some brokers do!

Time Gietzel is one canny operator, I really believe he has plans afoot and I reckon it relates to this comment ""It is time for Cameco to proceed with the next phase of our supply discipline decisions,"
Cameco have stated on numerous occasions now, that they would be the "go to supplier of enriched Uranium for North America and the world?"

If Cameco did use the enrichment process using technology developed by Silex and licensed to GLE? then they would get more enriched Uranium from every ounce of mined Uranium, compared to what the Centrifuge Enrichers can do, that would have to mean that they can produce the enriched Uranium using less mined Uranium to my way of thinking!

More to this than meets the eye!


Cameco restarts Canadian uranium operation​


09 February 2022


Share

Cameco has announced plans to restart uranium production at McArthur River/Key Lake, idled since 2018. The company plans to ramp up production at the operation in northern Saskatchewan to produce 15 million pounds U3O8 (5770 tU) per year starting in 2024, but aims to maintain "supply discipline", reducing production at Cigar Lake to 25% below its licensed capacity.

McArthur-River-aerial-(Cameco).jpg

"We see a market where fundamentals are shifting in our favour," Cameco President and CEO Tim Gitzel told investors in the company's conference call. Cameco's planned and unplanned production cuts, inventory reduction and market purchases, have since 2016 removed more than 190 million pounds U3O8 from the spot market, he said. The company has added 70 million pounds of long-term contracts to its portfolio since the start of 2021.


Coupled with increasing recognition around the world that nuclear energy will play a key role in achieving decarbonisation goals, it is easy to conclude that the uranium demand output is "durable and bright", he said.


"However, the uranium supply-side story paints a much different picture," he said. Persistently low prices have led to planned production curtailments at existing capacity, increased investment risk for new capacity, and the end of life of some mines. Secondary uranium supplies have in past filled market gaps, but such capacity is now declining significantly. This is further amplified by unplanned supply chain disruptions caused by the COVID-19 pandemic, global supply chain and economic challenges, while increased interest by investors sequestering large amounts of material has contributed to further thinning of the spot market. Increased interest in long-term contracting is emerging: Cameco has added some 70 million pounds of long-term contracts to its portfolio since the start of 2021, Gitzel noted.


"It is time for Cameco to proceed with the next phase of our supply discipline decisions," Gitzel told investors, operating McArthur River/Key Lake and Cigar Lake operating at less than licensed capacity starting in 2024. "We are taking a portfolio approach to our supply discipline. In 2021, we were operating at about 75% below productive capacity (100% basis), which came at a significant cost to our business. By 2024, we plan to be operating at about 40% below productive capacity (100% basis). This will remain our production plan until we see further improvements in the uranium market and have made further progress in securing the appropriate homes for our unencumbered, in-ground inventory under long-term contracts, once again demonstrating that we are a responsible supplier of uranium fuel," Gitzel said.


"Starting in 2024, it is our plan to produce 15 million pounds per year (100% basis) at McArthur River/Key Lake, 40% below the annual licensed capacity of the operation. At that time, we plan to reduce production at Cigar Lake to 13.5 million pounds per year (100% basis), 25% below its annual licensed capacity, for a combined reduction of 33% of licensed capacity at the two operations. In addition, we plan to keep our tier-two assets on care and maintenance, and production at Inkai will continue to follow the 20% reduction until the end of 2023 unless Kazatomprom further extends its supply reductions."


It will take some time to transition McArthur River/Key Lake from care-and-maintenance, Gitzel said. However, the operation could produce up to 5 million pounds U3O8 this year, depending on the completion of operational readiness activities including automation, digitisation and other projects, maintenance work and recruitment and training, and managing the potential risks from the pandemic and related supply chain challenges. Cameco will continue to meet sales commitments from a combination of its lower-cost production inventory and purchases, he added.


The company expects Cigar Lake production to be 15 million pounds U3O8 in 2022 (on a 100% basis).


McArthur River/Key Lake is described by Cameco as the world's largest high-grade uranium operation. Ore from underground mining operations at McArthur River is trucked 80 km south to be milled at Key Lake. Mining operations at Key Lake ended in 2002. Cameco is the majority owner and operator of McArthur River (69.8%) and the Key Lake mill (Cameco 83%), with Orano Canada owning 30.2% of McArthur River and 16.7% of Key Lake.


Nicolas Maes, CEO of Orano Mining, said the company is "fully confident" in Cameco's ability bring McArthur River/Key Lake into production on schedule. "Given the continued unbalanced uranium market conditions, the restart of McArthur gives us the opportunity to reduce production at Cigar Lake, extending the life of this asset and postponing the need for new projects in northern Saskatchewan," he said.


Orano Canada President and CEO Jim Corman said he was "optimistic" about the longevity of the Saskatchewan's uranium industry. "Following on the heels of our approval to expand the tailings management facility at McClean Lake, we now have a solid plan for uninterrupted production," he said.

By Haris Alic - The Washington Times - Wednesday, February 9, 2022

Nuclear power is getting a second look from congressional lawmakers as energy costs soar across the country, supply chain problems continue and President Biden pushes a robust climate change agenda to curb greenhouse gas emissions by 50% over the next decade.

Lawmakers say the present moment has underscored the need for a stable and cheap energy source that is not reliant on other nations.

“The numbers don’t lie,” said Sen. Tom Carper, Delaware Democrat and chairman of the Senate Environment and Public Works Committee. “Nuclear energy is by far the largest source of reliable, clean energy in our country — generating over half of our nation’s carbon-free electricity.”


Mr. Carper’s committee is working on two nuclear energy bills at the moment. One would streamline federal regulations on the construction of nuclear reactors and power plants, while authorizing more money for struggling facilities. The other would increase money for communities tasked with storing and cleaning up nuclear waste.

Both bills have garnered significant bipartisan support. Proponents say the measures signal a shift is taking place in how the public views nuclear power, given soaring prices of oil and gas and lingering supply chain issues.



A recent study by the conservative-leaning Heartland Institute indicates that American families paid roughly $1,000 more in energy costs in 2021. The surge resulted from actions taken by the Biden White House, including new restrictions on oil and gas drilling on federal lands and supply cuts among petroleum-producing nations in the Middle East.

“Current events serve as a reminder of the importance of this legislation,” said Sen. Shelley Moore Capito, West Virginia Republican. “International turmoil threatens to disrupt our nuclear fuel supply chain.”

Proponents hope America’s present troubles serve as a wake-up call to the benefits of nuclear power.

Once a stable and inexpensive source for energy production, nuclear power declined in the 1970s with the rise of the environmentalist movement. Since then, advocates have been working to showcase that nuclear energy, when regulated, is not at odds with efforts to combat climate change and protect the environment.

“I believe that we have an opportunity to help our nation’s nuclear energy industry transition into the future, while reducing carbon emissions and creating economic opportunities at home,” Mr. Carper said. “As we make that transition, it’s imperative that we prioritize safety and equity.”

Lawmakers have received some positive input from Mr. Biden and the White House. In December, the Energy Department created an office devoted to developing technologies that can reduce America’s dependence on fossil fuels.

Energy Secretary Jennifer Granholm has said a portion of the new office’s investment will go to developing smaller and “cleaner” nuclear reactors. The White House’s openness to nuclear comes as Mr. Biden is looking for ways to deliver on his pledge to reduce carbon emissions by more than 50% by 2030.

Experts say one of the easiest ways to help reach the goal is to decarbonize the electrical sector, which accounted for 25% of all U.S. greenhouse gas emissions in 2019. They say that nuclear power, which accounts for roughly 55% of all carbon-free electricity produced in the U.S., is an attractive alternative.

“It can serve as a powerful complement to increasingly inexpensive renewable energy by providing zero-carbon electricity and heat with 90% availability year-round independent season and weather,” said Armond Cohen, executive director of the Clean Air Task Force.

Despite these considerations, a large number of Democrats have yet to come around. The party has been averse to nuclear power for decades, mainly because of environmentalists who argue nuclear waste poses a grave threat even if disposed of properly.

Green activists have also invoked the threat of meltdowns and accidents, including the 1979 partial meltdown of a reactor at Pennsylvania’s Three Mile Island, as proof that nuclear power plants are unsafe.

“The science is clear,” said Jennifer Morgan, executive director of Greenpeace International. “Fossil gas and nuclear energy are dangerous, non-renewable and environmentally harmful technologies that under no circumstance should be categorized as sustainable solutions like solar and wind energy.”

Opposition to nuclear power from the Democratic Party’s base is one reason the issue has failed to advance significantly, despite renewed bipartisan support.

Even as Washington continues to vacillate, governors and state legislatures are embracing nuclear energy. The movement is growing in red and blue jurisdictions, alike.

West Virginia, one of the nation’s most Republican states, repealed a decades-old ban on nuclear power this year. While state officials say the building of nuclear reactors is likely years from fruition, the repeal signals they are open to the energy source.

“I think it is important to note that any development or placement of nuclear technologies in this state must be done thoughtfully and, above all, safely,” said Gov. Jim Justice, a Republican.

Similarly, last year state lawmakers in Illinois passed a comprehensive climate change package that includes significant development for nuclear energy. The deep-blue state, in particular, will spend $700 billion to shore up its nuclear power plants as part of a plan to generate 100% carbon-free energy by 2050.

In 2019, roughly 54% of all electricity generated in Illinois came from nuclear power, according to the U.S. Energy Information Administration.

“Frankly, the people of Illinois, the people of our nation, of the globe can’t wait for a clean energy future,” said Gov. J.B. Pritzker, a Democrat.

In embracing nuclear energy, state governments are following the lead of global powers in Europe.

France, for instance, generates nearly 70% of its electricity from nuclear power. French President Emmanuel Macron is pushing to build the country’s first nuclear reactor in decades to help combat dependence on foreign energy interests.

“To guarantee France’s energy independence, to guarantee our country’s electricity supply and achieve our objectives, in particular carbon neutrality by 2050, we are going … to relaunch the construction of nuclear reactors,” Mr. Macron said last year. “These investments will allow us to live up to our commitments.”

Britain, the Netherlands, Poland and the Czech Republic are following suit.

Still, the consensus is not universal in Europe. Germany, once a giant in nuclear energy production, has pledged to shut down its remaining nuclear power plants by 2022.

Switzerland, Belgium, Italy and Spain have moved forward with similar promises in recent years. The countries are planning to replace their reliance on nuclear energy with new investments in wind and solar power.

Critics note that such countries have become more reliant on foreign fossil fuels to ensure a stable energy supply. Germany, in particular, has imported Russian oil and natural gas at increasing levels to shore up its electrical grid.

“Germany is on a suicidal collision with energy reality,” said Steve Milloy, a member of former President Donald Trump’s transition team for the Environmental Protection Agency. “The irony is that as long as Germany insists on fretting and cutting emissions, the only viable alternative is nuclear power.”

Oklo, Argonne to commercialise advanced fuel recycling technology​

10 February 2022

California-based Oklo Inc and Argonne National Laboratory have signed an agreement formalising their commitment to commercialising recycling technology for advanced reactor fuel as part of a US Department of Energy-funded project.

The project involves work with electrorefining technology to recycle fuel for use in advanced fission power plants, Oklo said. Commercialising the technology will help reduce fuel costs for advanced fission, while reducing supply chain risks.

The partnership is an outcome of a cost-share project awarded by the Department of Energy's Technology Commercialisation Fund (TCF) that leverages R&D funding in applied energy programmes to mature promising energy technologies with the potential for high impact.

The TCF last year awarded more than USD30 million in federal funding, matched by more than USD35 million in private sector funds, for a total of 68 projects across 12 national labs. Oklo said it is matching DOE funding to Argonne for the project.

"This partnership with Argonne will help reduce fuel costs for advanced reactors, and therefore overall costs for power from advanced fission," Oklo CEO Jacob DeWitte said.

"There are tremendous energy reserves in used fuel that can provide emission-free power for entire nations for centuries while reducing the volume and radiological lifetime of waste material."

Oklo's proposed Aurora reactor design is a fast neutron reactor that uses heat pipes to transport heat from the reactor core to a supercritical carbon dioxide power conversion system to generate electricity. Using metallic high assay low-enriched uranium, or HALEU, fuel, the Aurora 'powerhouse' produces about 1.5 MWe and can also produce usable heat.

The DOE has issued a site use permit for a unit to be built at the Idaho National Laboratory, and the US Nuclear Regulatory Commission (NRC) in June 2020 accepted for review Oklo's combined licence application (COLA) for the plant, although the regulator in January this year said it had not received sufficient information to move forward with its review.

Oklo has recently said it is discussing next steps with the regulator, and is continuing its work on advanced fission "as key to a clean energy future".

Eric Loewen from GEH told the US senate a long time ago that there was enough nuclear material in the US to power all of it's needs for electricity production for over 100 years without needing one extra ounce of mined Uranium or 900 years if used in a moltern salt reactor, why bury something that could be radioactive for thousands of years when you could recycle it and get the other 95% of the Uranium from UNF and at the same time reduce what waste is there now by 80% and even what was left was reduced in radioactivity to around 300 to 400 years, still a long time I know, but compared to what happens today, it would make total sense to me, see link below.

See page 6





Processing of Used Nuclear Fuel​

(Updated December 2020)
  • Used nuclear fuel has long been reprocessed to extract fissile materials for recycling and to reduce the volume of high-level wastes.
  • Recycling today is largely based on the conversion of fertile U-238 to fissile plutonium.
  • New reprocessing technologies are being developed to be deployed in conjunction with fast neutron reactors which will burn all long-lived actinides, including all uranium and plutonium, without separating them from one another.
  • A significant amount of plutonium recovered from used fuel is currently recycled into MOX fuel; a small amount of recovered uranium is recycled so far.
A key, nearly unique, characteristic of nuclear energy is that used fuel may be reprocessed to recover fissile and fertile materials in order to provide fresh fuel for existing and future nuclear power plants. Several European countries, Russia, China and Japan have policies to reprocess used nuclear fuel, although government policies in many other countries have not yet come round to seeing used fuel as a resource rather than a waste.

Some might say that the above is bad news for Uranium miners, not so, because most of the new coming SMR's will run on HALEU (enriched Uranium between 5% and just under 20% enrichment) which is not military grade and cannot be used for weapons, once that fuel is spent it could be used in a molten salt reactor to burn the wastes still left in it (still 95% of the usable Uranium) as fuel, so I believe (must be careful saying that!) we will see both SMR's and existing reactors using mined Uranium and MSR's burning the wastes from those reactors, which will reduce the amount of existing and new UNF going forward that requires burial by 80% and it is also far less radioactive for a much shorter period as well, what is not to like about that?

The chemical slurry is fed into a centrifuge processing system, which looks like a giant pillbox with each compartment containing a rotor for mixing. The solution flows from one end of the system to the other, mixing, centrifuging, adding, or subtracting different chemical components along the way. Throughout the process, real-time monitoring provides critical insights into what adjustments need to be made to maintain specific chemical compositions.
“Real-time monitoring was pivotal to determining exact chemical elemental ratios. We really focused on the uranium-plutonium percentages and knew exactly what they were at any given point."

They were using CENTRIFUGE, which is only second generation technology, surely the latest third generation technology using lasers would be much better and more efficient?
What they do here is remove some of the Nuclear poisons that have built up in the fuel which renders the fuel unusable, take out the poisons and they are back in business with a new fuel derived from used nuclear fuel.

Imagine filling up your gas tank with 10 gallons of gas, driving just far enough to burn a half gallon and discarding the rest. Then, repeat. That is essentially the practice that the U.S. nuclear industry is following.
Spent nuclear fuel from power plants still has 95% of its potential to produce electricity. Current plans are to dispose of the spent nuclear fuel in a geologic repository. So, why is it not recycled? It turns out that separating usable versus unusable parts of spent nuclear fuel is complicated.

“Spent nuclear fuel contains roughly half of the periodic table. So, from a chemistry standpoint, there’s a lot going on,” said Gregg Lumetta, PNNL chemist and laboratory fellow. “And to reduce proliferation risk, it is best if pure plutonium is not produced at any point in the separation process.”
Researchers from Pacific Northwest National Laboratory (PNNL) developed an innovative capability to rapidly separate, monitor, and tightly control specific uranium and plutonium ratios in real-time—an important achievement in efficiently controlling the resulting product and safeguarding nuclear material.

A spent nuclear fuel recycling twofer​

With the rising demand for carbon-free power, nuclear is an option in the green-energy mix, particularly with advanced reactors on the horizon. Yet, there are still some big challenges to overcome: what happens to spent nuclear fuel that currently goes unused, and how do we power advanced reactors?
"Perhaps, these challenges have the same solution—recycling spent nuclear fuel to make new fuel,” said Amanda Lines, a PNNL chemist. “In a world of increased energy demand challenged by growing carbon footprints, how can we better use spent nuclear fuel?”
New advanced reactors could be designed to run off recycled fuel. But recycling spent nuclear fuel means separating the energy-generating plutonium from everything else in the mix while not separating it in pure form, which is viewed as a proliferation risk. Also, the final product must be a precise ratio of uranium to plutonium to produce new fuel that can be reused in nuclear reactors.

Separating spent nuclear fuel is like trying to deconstruct vinaigrette salad dressing with the goal of moving ingredients from vinegar to oil.

The chemical slurry is fed into a centrifuge processing system, which looks like a giant pillbox with each compartment containing a rotor for mixing. The solution flows from one end of the system to the other, mixing, centrifuging, adding, or subtracting different chemical components along the way. Throughout the process, real-time monitoring provides critical insights into what adjustments need to be made to maintain specific chemical compositions.
“Real-time monitoring was pivotal to determining exact chemical elemental ratios. We really focused on the uranium-plutonium percentages and knew exactly what they were at any given point,” said Lines.
Real-time monitoring also improves efficiency, reduces costs, and takes an established process into a more modern and futuristic realm.
"Ultimately, it empowers researchers and operators by providing nearly instantaneous information to help control and understand chemical processes,” said Lines.
PNNL’s real-time monitoring capabilities have exponentially evolved over the past 25 years, intersecting with a long history of fuel recycling and separations research.

From industrial to microscale​

Separations researchers often rely on manmade, simulated spent nuclear fuel to mimic the chemical processes because actual spent nuclear fuel is expensive to acquire and study. However, simulated spent nuclear fuel is also costly, particularly at the large, industrial scales necessary to study bulk recycling and separations processes.
To address that challenge, PNNL has developed complementary approaches that can be done at a much smaller, and much less costly, scale. Using microfluidics, or lab-on-a-chip, technology coupled with real-time monitoring, researchers can track chemical processes on something the size of a microscope slide.
“We can run the same types of separations studies and track the exact composition of uranium fuel components and fission products throughout the recycling processes, similar to what is done at a lab or industrial scale,” said Lines.
The researchers are also able to use actual spent nuclear fuel because the scale is so much smaller. “This technology is cost efficient and enables incredible opportunities to develop and advance recycling approaches,” said Lines.

From reducing the amount of radiation in high-level radioactive waste to developing a separation process to remove hazardous elements in spent fuel, PNNL has a long history solving some of the nation’s toughest spent nuclear fuel challenges.
"We’ve been advancing fuel-cycle operations for decades,” Lumetta said. “This most recent work is a platform for us to expand upon as we continue to pursue chemical separations for advanced fuel-cycle options.”
The research on fuel-cycle separations and real-time monitoring further expands PNNL’s capabilities into other spent nuclear fuel applications for the future. Two recent journal articles highlighted these research findings, sponsored by the U.S. Department of Energy’s Office of Nuclear Energy through the Nuclear Technologies Research and Development Program:

Germany has made a rod for it's own back by not wanting Nuclear, they only want Gas, which will be supplied from Russia, something that in my opinion is a foolish move?
This bit from this article says it all really -: "A summary will be provided instead, allowing then to move towards a broader reflection on the European electricity system launched 30 years ago, and under constant reform … and which does not work as desired."

If Germany doesn't want nuclear then that's OK with me, but in effect by not allowing Nuclear into the Taxonomy then they are basically saying we are right and you are wrong, they hold a gun to the head of all of Europe not just themselves because not allowing nuclear into the Taxonomy will mean that money will be harder to find and will be dearer for those countries that do want Nuclear, it may not come to that anyway because there are more countries that want it than do not, and there are more countries that want it than not, but I see this as Germany being arrogant!

No one is saying that wind and solar are not wanted, but it needs a good source of baseload power for it to work as intended, without it, it leaves their power supplies to the vagueries of what the environment provides and as we all know they can be intermittent, Germany will still rely on Nuclear power though by using important power imported from France, go figure, so where would be the justice of this by making it harder for France from gaining funding at a reasonable price?

Australia is heading down a similar path as Germany in my opinion, wait for the price of energy to rise then!


Viewpoint: Taxonomy and the need to reform the EU's electricity system​


11 February 2022

The debate over sustainable investment rules has highlighted the differences within the European Union on the ideal and/or possible energy mix in a carbon-constrained world where the EU wants to be a role model. It is time to reform the electricity system in Europe, writes Marc Deffrennes, from the weCare alliance of NGOs which favour using renewables and nuclear to limit carbon emissions.

It is not the purpose in this article to give full details on the EU Taxonomy for Sustainable Financing, a process launched more than three years ago by the European Commission. A summary will be provided instead, allowing then to move towards a broader reflection on the European electricity system launched 30 years ago, and under constant reform … and which does not work as desired.


The harsh discussions in Brussels and the European capitals on the inclusion of nuclear and gas in the Taxonomy, combined with the energy crisis directly impacting the European citizens in their daily life, provide an opportunity to take a step aside and understand the need for a deep reform of the electricity system in Europe.


The purpose of the EU Taxonomy for Sustainable Financing is to guide financing institutions, and investors in general, in deciding where to invest while respecting principles of sustainability. This Taxonomy is embedded in EU Green Deal policies which aim to reach carbon neutrality in 2050 at EU level.


Therefore, the main general criteria for an activity to be Taxonomy compliant is to contribute to climate change mitigation or adaptation. In addition, such an activity must also respect the DNSH (Do No Significant Harm) criteria - meaning it can prove it causes no significant negative environmental impact.


The main principles of the Taxonomy were approved at EU level in June 2020, giving to the Commission the full power to develop further the detailed criteria by using Delegated Acts (once published by the Commission, Member States and the European Parliament have up to six months scrutiny period. No amendments are possible: it is a take or leave process. To reject a Delegated Act, a large, hard to reach, majority is necessary in Council and a simple majority in Parliament, otherwise it is approved de facto).


The first Delegated Act - related to the climate mitigation and adaptation criteria - was published by the Commission in June 2021. It includes activities connected to the deployment of Renewable Energy Sources (RES). Nuclear and gas were not included, with the Commission proposing to cover these energy sources in a dedicated Complementary Delegated Act (CDA). The European Parliament approved the first Delegated Act in October and the Council by the deadline in December, with nevertheless a noticeable number of Member States either opposing (including France) or abstaining (including Germany).


The draft CDA was issued on 31 December 2021 by the Commission. It gave three weeks to the Member States and the so-called experts of the Sustainable Finance Platform (SFP, established by the Commission as a follow-up of the former Technical Expert Group) to provide comments, after which the Commission would adopt the CDA following the approval by the College of Commissioners.


The Council and the Parliament will then, following the same pattern as for the Delegated Act, have six months scrutiny before approval or rejection of the CDA. The content of the draft CDA, as soon as it came out, led to significant controversy and divergent positions. Both nuclear and gas are considered as helpful for the transition towards carbon neutrality in 2050, nuclear being carbon-free and gas better than coal.


The draft CDA, which might come from a kind of deal between France (supporting nuclear) and Germany (supporting gas), sets a number of constraints in the form of Technical Screening Criteria to be respected for related activities to be recognised as Taxonomy compliant.


Numerous organisations representing different opinions and using diverse channels of communication, have reacted providing their views. On 21 January, the SFP published its analysis, basically opposing the inclusion of nuclear and gas in the EU “Green” Taxonomy. On 2 February, the College of Commissioners approved a slightly revised version of the CDA, which will be published, for scrutiny by the Council and the Parliament, for approval or rejection.


This Taxonomy saga revealed, but also reinforced, the major divergences within the EU on the ideal and/or possible energy mix in a carbon-constrained world, where the EU wants to be a role model. A major concern with the Taxonomy, a real flaw from the start, is that it is based on a concept of sustainability which is too restrictive, and currently only limited to "green" environmental considerations.


Instead, one needs to fight for societal sustainability, a much wider concept based, when looking at energy, on a sound balance between the three pillars of (i) environment protection, (ii) economics and affordability, and (iii) security and reliability of supply. One might give more weight to one pillar over the others, but a balance is needed, otherwise it is not viable for the society.


This "green" approach, one can say dogma, is not new at EU level. The change in words used to name and foster the EU decarbonisation endeavour from "A Clean Planet for All" to the "Green Deal" is symptomatic of the profound influence of the "green" lobby in the EU Institutions.


And this is counterproductive, if not dangerous, for European cohesion, at a time when it is so needed on the wide international and geopolitical scene. It is not to say that environmental considerations, beyond decarbonisation, are not to be handled with the greatest care, but one must realise that other parameters have also to be considered on an equal footing and in taking all views into account.


Coming back to energy, a problem comes from the dash for intermittent renewables, very much promoted by some Member States under pressure of their green political parties, and strongly reflected at EU level with ever increasing targets to be reached.


It seems attractive to try to use "free" energy from the wind and sun, but this energy is intermittent and requires backup installations. There are dreams that massive electricity storage, via batteries, including decentralised in each family using its electric car, or via hydrogen production in the P2P process (Power to Power: “green” electricity producing hydrogen to be burned to produce electricity), then with a very poor efficiency, will be the solution.


Sometimes dreams do come true, but this seems more like a myth. The reality is that the dash for intermittent renewables is associated with a dash for gas. Is it surprising that Germany, which is championing intermittent renewables and is working at EU level (with Austria, Luxemburg and some others) to impose them, is at the heart of the Nord Stream pipelines project?


Each Member State, for sure, decides, based on its democratic process, what energy mix it want to use. But that principle, enshrined in Article 194 of the European Treaty must be fully applied: if other Member States decide to rely on zero-carbon nuclear energy instead of carbonised gas, and to limit their use of intermittent renewables for electricity production to a manageable fraction, this should be fully respected.


What a manageable fraction means depends on local conditions. Different studies show that, in Europe, an economic optimal could be around 35%, without even mentioning the technical constraints. This brings us to the issue of the cost of electricity and what it contains.


There are three components in the cost. The first component is electricity production costs, at the exit of the production facility and usually called the Levelised Cost of Electricity and is composed of the overnight capital cost of construction and the financing costs, the fuel and operation costs, provisions for waste management, etc. The second is composed of system costs, beyond the production facility, the costs of the electricity system operation including flexibility and balancing costs, which are particularly important for intermittent renewables, but also connections, transmission and distribution costs. The last component is external costs, in particular social and environmental costs, including a CO2 tax when fossil fuels are used to generate electricity.


Up until recently, only the Levelised Cost of Electricity has been used to compare the cost of electricity production with different sources. This is not enough. It is necessary, to allow a fair comparison, to take all costs into account. Therefore, the cost of intermittency (meaning the cost of the backup, be it by storage or fossil plants) needs to be attributed to the Levelised Cost of Electricity of intermittent renewables and not hidden in overall system costs. Without forgetting that the cost of CO2 needs to be added when using fossil fuels as backup for intermittent renewables.


Remembering that the cost of deployment of intermittent renewables in Germany has cost the country around EUR500 billion (USD565 billion) over 20 years, without even counting the cost of backup technologies, gives us an idea of the economic and social impact of such a policy if it were to be imposed at EU level.


The next problem hindering the application of Article 194 of the Treaty is the electricity market, which was launched in the 1990s following the liberalisation wave of the Reagan-Thatcher era, very much promoted by the European Commission and adopted by the Member States.


The promise was to reduce the price of electricity for the consumers. After 30 years of de-structuring, unbundling, restructuring, adding layers of rules over layers of rules, where do we stand today? What we have is not working: it is simply not delivering on its promise.


The original concept of the electricity market became further flawed when intermittent renewables came into the picture
: the system was mixing apples and pears. Mixing small decentralised intermittent facilities, but having priority access, with large centralised dispatchable facilities, simply cannot work properly.


Today the cost of electricity and its price are decoupled. What is paid by the consumer does not reflect the true cost of the electricity. Consumers have no idea anymore of what is behind their bill. It is too complex to understand, and there are too many hidden interests.


It is high time to reform, deeply reform, the electricity system (avoiding the term market) in Europe and to provide long-term vision on how it can function in a stable and healthy way, integrating the principle that electricity is a common good and not a commodity, with the obligation to have permanent equilibrium between production and demand. This might best be done under the control of the State, which bears responsibility towards its citizens-consumers-taxpayers, and probably via vertically integrated organisations.


And to respect the principle of Article 194, this electricity system must ensure that the energy mix chosen by one Member State does not hinder, or even perturb the choice of the others. This may appear anti-European. It is not, on the contrary. One has to take full notice of what the Taxonomy has revealed: the deep divide between the green pro-100% intermittent renewables, the pro-nuclear and the pro-gas.


Pursuing, without a profound revision of the way Article 194 is applied, by ensuring that each Member State can really decide on its own on its energy mix, without undue pressure being brought by others, brings a much greater risk for the cohesion of the European Union. And this profound revision implies, necessarily, a reform of the European electricity system.


Energy has been at the core of the creation of the EU, it should not be a source of deep divide. Energy is the blood of the economy. The time has come to go beyond the green dogma, beyond pure environmental considerations, and to take full grasp of the sustainability of the European society, for the wellbeing of the European citizens. Member States should instruct the European Commission to start working along the lines above and come back soon with sound proposals. Time is at stake, and with other parts of the world moving ahead, it is also a geopolitical priority.

Perhaps Germany may have to rethink where it is headed? seems they might be?
And France is having problems with some reactors at the moment, that may increase the price to Germany even more until France builds further nuclear capacity, which they said they will be https://www.reuters.com/business/en...energy-roadmap-this-week-minister-2022-02-08/

So maybe France saw the folly that Germany has created for themselves and decided that they could supply the power that Germany won't?



"Since November, the amount of natural gas arriving in Germany from Russia has plunged, driving prices through the roof and draining reserves. These are changes that Gazprom, Russia’s state-controlled energy behemoth, has been regularly pointing out"
.“As much as 85 percent of the gas injected in Europe’s underground gas storage facilities last summer is already withdrawn,” Gazprom said on Twitter a couple of weeks ago, adding that “facilities in Germany and France are already two-thirds empty.”
