New EDF boss at mercy of ‘to-do list’ that ousted his predecessor

The new boss of French state-owned energy group EDF faces the same nearly
impossible tasks that led to the ousting of his predecessor: satisfying the
government’s often contradictory demands for cheap power to help industry
and the construction of costly new nuclear reactors.
Bernard Fontana, nominated as chief executive on March 21, is a seasoned industrialist who
has run EDF’s engineering arm Framatome for nearly nine years. He will
seek to avoid the fate of the previous chief executive Luc Rémont, removed
last month after just over two years because of repeated clashes with the
state.
On Fontana’s to-do list will be repairing relations with the
government, the company’s only shareholder, striking energy supply deals
with some of EDF’s biggest industrial clients, while also advancing plans
to build six nuclear reactors in just over a decade — a key initiative of
French President Emmanuel Macron, which was announced three years ago.
Fontana’s main challenge is to balance competing pressures of delivering
low rates for power, demanded by government and industry, while generating
profits that will help support vast investments required to launch new
nuclear reactors.
The company ran over budget and behind time on the
completion of Flamanville, a new nuclear reactor in northern France, and
faces budget and timing issues with the UK’s Hinkley Point. It has also
faced criticism that it is yet to outline timelines and costings for the
project to build the six new nuclear reactors, which were originally due by
the end of 2024.
Last month, the government pushed back the launch date
from 2035 to 2038, although observers have long considered the 2035 target
unachievable. In short, Fontana’s success will depend on whether he can
walk the tightrope of running EDF profitably while delivering the vast
capital outlay needed to reboot France’s nuclear sector. This will
require a major shift from Rémont’s uncompromising approach. “If
Fontana has taken the job, he’s understood the lesson [from Rémont’s
sacking]. If he hasn’t, he’s an idiot,” said another adviser.

France’s UK energy apathy poses nuclear problem for Labour

France’s public spending watchdog is advising the country to cut back on its involvement in UK nuclear projects
Brad Gray, Tortoise 27th March 2025, https://www.tortoisemedia.com/2025/03/26/frances-uk-energy-apathy-poses-nuclear-problem-for-labour
EDF has reduced its stake in the Sizewell C nuclear power plant by a further 7.7 per cent, leaving the UK government with an 83.8 per cent share.
In 2022, a government buy-out to allow the Chinese state to exit the project made the UK the leading investor.
Last week Emmanuel Macron fired the EDF chief following a row over energy prices, and France’s public spending watchdog is advising the country to cut back on its involvement in UK nuclear projects and focus on small modular reactors instead.
As France reduces its investment, taxpayers are likely to foot more of the bill than anticipated – a tough pill to swallow as the chancellor slashes public funding.
When complete, Sizewell C is forecast to provide up to 7 per cent of the country’s electricity needs, with reactors lasting 60 years. Right now it’s a political headache.
EDF reduces stake in Sizewell C as boss sacked

the sacking raises “further fundamental questions about the wisdom of proceeding with the Sizewell C ‘Replica’ project of Hinkley Point C in which EDF is set to be deeply involved”
“Clearly Sizewell C could not reach a Final Investment Decision without taxpayers shouldering the bulk of the project’s massive cost – a hugely controversial choice given that the Chancellor is currently scrabbling around to save as much money as possible.“
25 Mar, 2025 By To s-sacked-25-03-2025/ https://www.newcivilengineer.com/latest/edf-reduces-stake-in-sizewell-c-as-boss-sacked-25-03-2025/
EDF’s ownership of Sizewell C has decreased to 16.2% and the UK government’s stake increased to 83.8%. Meanwhile, the French company’s chief executive has been axed and its financial stability has been called into question.
The UK’s flagship gigawatt-scale new nuclear projects under construction – Hinkley Point C in Somerset and Sizewell C in Suffolk – are both subject to intense scrutiny as costs rise and timelines slip.
Hinkley Point C is late and over budget, and Sizewell C is awaiting its delayed final investment decision (FID) which is scheduled to be made at the Spending Review on 11 June. The FID will reveal the final determination of who will fund the project and how. The government has already invested several billion pounds in developing it.
Hinkley Point C’s costs rose from around £25bn in 2015 to up to £34bn in 2024, and Sizewell C is projected to cost £40bn – double what it was estimated by EDF and the UK Government to cost in 2020. However, the Treasury disputes this latter figure.
EDF Sizewell C ownership stake reduced
On 24 February 2024, NCE reported that EDF was appearing to scale back its proposed ownership ambitions of Sizewell C.
EDF’s 2024 Annual results document laid out its contribution to the power plant, which is “subject to some conditions, including […] a share in ownership of the project of 10 to 19.99%, including a cap on financial exposure in value.” It also requires “a return on capital expected by EDF as an investor in line with market return for this type of assets, risk allocation profile and its investment policy.”
It is understood that the reason for selecting 19.99% rather than 20% is because a company buying 20% would have to set up a subsidiary entity to take the ownership.
Credit ratings agency Fitch Ratings announced in a ‘Rating Action Commentary’ on 21 March 2025 that the Sizewell C’s owners – the UK Government and EDF – had changed their ownership stakes.
EDF previously confirmed in its 2024 half year results that Sizewell C is owned 76.1% by the UK Government and 23.9% by EDF.
Fitch’s announcement said: “As of end-2024, the project was owned 83.8% by the UK government and 16.2% by EDF, down from 49.4% at end-2023.”
This marks a fresh drop in EDF’s ownership by 7.7 percentage points.
The decrease comes after French public spending watchdog Cour des comptes said EDF should scale back involvement in UK nuclear projects.
Macron sacks EDF chief and funds EDF reactors
In France, where the government has political control of the entirely state-owned EDF (Électricité de France), Macron fired the company’s chief executive Luc Rémont.
The UK’s Daily Telegraph linked Rémont’s ousting to EDF’s planned electricity price hikes for French industrial customers, of which Macron had promised to “take back control”.
Adding further pressure to EDF’s leadership, French building materials company Saint-Gobain chairman and chief executive officer Benoit Bazin, speaking to French business news channel BFM Business, accused EDF of “giving the middle finger to French industry”.
It has also been reported that the French state has agreed to issue a single subsidised loan “covering at least half the construction costs of six nuclear reactors”, according to the president’s office. It is understood that the six reactors are at the pairs at Penly, Gravelines and Bugey in France.
Former energy secretary reacts to ‘extremely concerning’ developments‘.
Backbench Conservative peer Lord Howell of Guildford reacted to the news. Howell was energy secretary in Margaret Thatcher’s government which supported the construction of nuclear power plants.
He described the reduced stake in Sizewell C as “one more development in growing concern about EDF’s capacity or ability to continue with Hinkley Point C project or take a large (20%+) position in the Sizewell C proposed project.”
Reflecting on the sacking of the EDF boss, he said this is “An extremely worrying development.”
He went on to say the sacking raises “further fundamental questions about the wisdom of proceeding with the Sizewell C ‘Replica’ project of Hinkley Point C in which EDF is set to be deeply involved”
Anti-Sizewell C groups say ‘alarm bells should be ringing’
Stop Sizewell C executive director Alison Downes said: “EDF has not contributed a single penny financially to Sizewell C for well over a year now, and is under growing pressure in France, not only having lost its boss but to scale back its international commitments across the board.
“Clearly Sizewell C could not reach a Final Investment Decision without taxpayers shouldering the bulk of the project’s massive cost – a hugely controversial choice given that the Chancellor is currently scrabbling around to save as much money as possible.
“Rachel Reeves should cancel Sizewell C now and redirect those funds to the Warm Homes Plan, which would lower energy bills and create jobs in every constituency.”
Chancellor Rachel Reeves has proposed austerity measures for the welfare state, which she says are needed to fund infrastructure developments, ahead of the Spring Statement and Spending Review.
Cuts to welfare, particularly covering disability and unemployment support, are proving to be unpopular with dozens of MPs on the left of the Labour party.
A Together Against Sizewell C (TASC) spokesperson said: “Alarm bells should be ringing as the UK government stake in Sizewell C increases to 84% with only the UK taxpayer currently funding Sizewell C’s development costs.
“This begs the question, ‘Why are EDF refusing to put any further money into Sizewell C?’ EDF have decided to build no more of this reactor design in France, indicating they have no confidence in the EPR design destined for Sizewell.”
The spokesperson went on to say: “EDF are broke, as evidenced by their desperate search for cash to finish Hinkley Point C’s construction.
“This is hardly a secure basis for the UK government to continue in partnership with EDF and certainly not a good advert to encourage potential investors.”
Referencing EDF’s plans for a final stake to be as low as 10%, TASC said: “This evidences that even the developer considers the Sizewell C development to be inherently
EDF and the Department for Energy Security and Net Zero did not respond to requests for comment.
France delays EPR2 reactors to 2038
The 4th meeting of France’s Nuclear Policy Council (CPN – Conseil de
politique nucléaire), chaired by President Emmanuel Macron, decided to
delay the commissioning of EPR2 reactors to 2038 – a postponement of
three years. The CPN, which has been held regularly since 2022, defines the
main orientations of national nuclear policy.
The EPR2 programme, announced
in February 2022, envisages the construction of six upgraded EPR reactors
with an option for eight more. The first three pairs of EPR2 reactors are
planned for the Penly, Gravelines and Bugey NPP sites. Construction is
expected to start in 2027. The cost was originally estimated at €51.7bn
($56.4bn), but this was revised upwards to €67.4bn in 2023, according to
the Court of Auditors. Taking inflation into account, a total budget of
nearly €80bn is now being considered.

Macron ousts EDF boss accused of giving French industry ‘the middle finger’

Luc Rémont will be replaced in a reshuffle with factory energy prices set to soar
Alex Singleton, Business Reporter, https://www.telegraph.co.uk/business/2025/03/21/macron-ousts-boss-state-run-edf-french-energy-prices-surge/
Emmanuel Macron has ousted the boss of the state-run EDF after French industrialists revolted over its high electricity prices.
Luc Rémont is to be replaced in a surprise reshuffling of the company’s top ranks, Mr Macron’s office said on Friday. Mr Rémont has run the the state-owned energy giant since November 2022.
The shake-up follows an outcry over the high energy prices EDF is poised to charge factories. Benoît Bazin, the boss of building materials giant Saint-Gobain, had accused EDF of “giving the middle finger to French industry” by increasing prices.
Rules that force EDF to sell energy to major industrialists at below-market prices are set to expire at the end of the year and the generator had announced plans to raise its prices.
Industry group Uniden, which represents dozens of France’s biggest manufacturers including Renault and steelmaker ArcelorMittal, claimed EDF was “deliberately turning its back” on French businesses at a time when manufacturers were “exposed to unprecedented non-European competition that threatens the very survival of many sites”.
The row is embarrassing for Mr Macron, who had pledged to “take back control of electricity prices” and who sees cheap electricity as a way of securing the French economy. Two years ago, he fully nationalised EDF by buying the 16pc of the company the government did not already own.
The shake-up comes days after the Macron administration said it had agreed state financing for six new nuclear reactors to be built by EDF over the coming decades.
Anger over high industrial energy prices is rising in the UK too. UK factories pay 50pc more for electricity than rivals in France and Germany, and four times as much as American plants. High prices have been blamed on net zero and slow-moving plans to expand nuclear power.
Warnings from industrialists that net zero energy policies are damaging the economy have fallen on deaf ears. Ed Miliband, the Energy Secretary, said this week the UK Government was “absolutely up for the fight” over net zero.
EDF is one of the largest players in the UK nuclear power market, after buying three formerly nationalised regional electricity boards and the nuclear operator British Energy.
It is currently building the UK’s first new nuclear power station for over 20 years, Hinkley Point C, and plans to embark on the construction of another, Sizewell C. But in January, the future of this new project was thrown into doubt after the French state auditor warned it against embarking on risky new foreign projects.
EDF declined to comment. The French government has been approached for comment.
French government ousts head of nuclear power group EDF.

Luc Rémont’s exit comes after months of tension over plans for new reactors and clash over pricing strategies.
France has ousted the chief executive of the
state-owned nuclear power group EDF after months of tensions over strategy
and the risk of cost overruns in the construction of six new reactors.
Luc Rémont, who had been at EDF since November 2022, would be replaced by
Bernard Fontana, the current head of Framatome, a subsidiary of EDF that
builds reactors and components, the Élysée Palace said on Friday.

EDF runs the country’s fleet of 57 nuclear plants that generate roughly 70
per cent of France’s electricity, and commercialises nuclear projects
abroad. Rémont succeeded in the initial challenge of restoring the output
of the fleet of reactors after a period plagued by technical problems, and
was in the early stages of a plan to build new more powerful, yet costly
ones, known as the EPR2.
But his term was marred by continued spats with
the state, which nationalised EDF through buying out the minority
shareholders in 2023. The Elysée decided not to renew Rémont’s
three-year term that was set to expire in June.
A major point of contention
was over Rémont’s plans to revamp how EDF sells electricity to big
industrial companies with energy-intensive activities. In the past, the
company was legally required to sell fixed amounts of electricity to them
at a price approved both by the French government and the European
Commission.
With those rules expiring next year, Rémont had been set to
combine market pricing with the signing of long-term contracts with
customers in energy-intensive industries. But the offers attracted few
companies since the terms and prices were less attractive. In parallel to
long-term contracts, EDF said this month that it would launch a new
auction-like process for other industries, including foreign buyers, in a
move that angered energy-intensive groups in France.

Macron Ousts EDF CEO as Tension Rises on French Power Costs

The French government said Electricite de France SA Chief Executive Officer Luc Remont is stepping down as the state-owned utility faces increasing complaints from large industrial clients over the cost of electricity.
Author of the article:, Bloomberg News, Francois de Beaupuy, https://financialpost.com/pmn/business-pmn/macron-ousts-edf-ceo-as-tension-rises-on-french-power-costs 21 Mar 25
(Bloomberg) — The French government said Electricite de France SA Chief Executive Officer Luc Remont is stepping down as the state-owned utility faces increasing complaints from large industrial clients over the cost of electricity.
President Emmanuel Macron is considering appointing Bernard Fontana, the 64-year-old senior executive vice president in charge of the company’s Industry and Services unit, as the new chairman and CEO, the president’s office said in a statement Friday. Remont, 55, has held the positions since November 2022.Article content
“The choice that the government has long supported is electricity that is abundant, clean and not too expensive, and it’s based on this choice that Bernard Fontana’s nomination has been made,” French Prime Minister Francois Bayrou said on a trip to Bourges, central France. “He’s an industrialist, which means he’s used to running teams and speeding up projects.”
Tensions between the government, EDF and major customers have been mounting over the utility’s electricity offerings. Representatives of power-hungry users, such as chemical makers, have said EDF’s new offers aren’t attractive enough, threatening their competitiveness, while rivals in the US and Asia enjoy cheaper energy. Their concerns have been exacerbated recently by sluggish economic growth, uncertainties over gas prices due to the Ukraine war, and mounting trade tensions between Europe, the US and China.
A French regulation that forces the nuclear behemoth to sell more than a quarter of its atomic output at a steep discount to current wholesale prices expires at year’s end. Meantime, the debt-laden utility said it needs to increase expenditure on nuclear projects and the power grid to help the country’s energy transition.
On Thursday, Benoit Bazin, the CEO of French glass and building materials producer Cie. de Saint-Gobain, said on BFM Business television that his company has delayed investment in France because it cannot predict energy costs from next year. Meantime, it has invested in Norway and Canada to electrify plants, and will soon do the same in Spain.
Bazin said he was “extremely shocked” by Remont’s recent decision to auction long-term power supply contracts to rival producers and suppliers, broadening offers that initially were reserved for its large electricity clients.
“EDF is a national company that has a public service mission on the competitiveness of the French industry,” the Saint-Gobain CEO said. “France won’t keep its industry, nor re-industrialization and decarbonization if we keep walking on our head.”
Shutting Sites
Earlier this week, Marc Schuller, chief operating officer of French chemical maker Arkema SA, said during a parliamentary hearing that talks with EDF over new power contracts were “advancing very slowly.
“If nothing is done, we’ll have to consider shutting down sites and stopping some activities because we wouldn’t be competitive anymore,” Schuller said.
Fontana has held a variety of management positions during his career at steelmakers ArcelorMittal SA and Aperam SA, including CEO of Swiss cement maker Holcim Ltd. Within EDF, he’s been in charge in recent years of Framatome, the unit that makes large equipment for nuclear plants.
Beyond easing tensions with large customers, the future boss of EDF will have to complete complex talks with the French and UK governments over the financing and construction of new reactors, which are key planks of these countries’ net-zero ambitions.

EDF may get state loan for six new reactors

France’s Nuclear Policy Council – headed by President Emmanuel Macron –
has agreed that a subsidised government loan should be issued to
state-owned power utility EDF to cover at least half the construction costs
of six EPR2 reactors.
World Nuclear News 18th March 2025,

Turbine, cooling: these unforeseen events that keep the Flamanville EPR at a standstill.

EDF is extending an unscheduled shutdown of the Flamanville EPR until the end of March in order to make adjustments to the turbine. During its first 100 days of operation, the nuclear reactor will have undergone 76 days of maintenance.
By Amélie Laurin, March 6, 2025
EDF had warned: the ramp-up of the Flamanville EPR, the first nuclear reactor to be commissioned in France in twenty-five years, would be very gradual. The public group has once again shut down, for a month and a half, its Normandy pressurized water reactor, which had been connected to the electricity grid on December 21, the first day of winter.
These maintenance operations were not planned and are the result of technical difficulties. They began on February 15 and are due to continue until March 30, after being extended three times.
Turbine heating
This work follows two initial suspensions of electricity production at Flamanville, between Christmas and mid-January, and at the turn of February. Two shutdowns that were, themselves, scheduled. In total, the reactor will have been immobilized for 76 days, during its first 100 days of operation.
The cause: various technical adjustments. In mid-February, the EPR stopped producing electrons due to an insufficient water flow in the seawater cooling circuit, which is only used “in exceptional situations”. This was followed by an intervention “on a temperature probe of the main circuit”, specifies a regulatory press release.
EDF appears to consider reduced final stake in Sizewell C nuclear to as low as 10%

New Civil Engineer, 24 Feb, 2025 By Tom Pashby
French state-owned energy giant EDF which is the sole operator of nuclear power plants in the UK has said it will consider becoming a 10-19.99% owner of Sizewell C, having previously committed up to 20%.
EDF previously confirmed in its 2024 half year results that Sizewell C is owned 76.1% by the UK Government and 23.9% by EDF.
Despite the final investment decision (FID) still not having been made, approximately £5.5bn of taxpayer money has been committed to the scheme, and contractors have been awarded £2.5bn of works which are underway ahead of main construction.
Speculation about the ownership of Sizewell C abounds because of the secrecy around the process, the potential for much of the £40bn investment to be stumped up by the taxpayer, and Centrica’s recent comments which weakened confidence in the scheme.
Centrica CEO Chris O’Shea said the energy company’s stake in Sizewell C could be “between 1% or 2% and 50%”.
“I’m not going to commit Centrica money for something that won’t give us the returns we need.”
EDF previously said it would own maximum 20% stake
In a press release from EDF on 20 December 2022, the company said: “EDF will only retain a minority stake of a maximum of 20% at final investment decision”.
Since the 20% figure was announced, French public spending watchdog Cour des comptes said EDF should scale back involvement in UK nuclear projects.
The auditor said “a final investment decision on [Sizewell C] should not be approved until a significant reduction in EDF’s financial exposure to the Hinkley Point project has been achieved.
………………….Ownership stake scaled back to 10-19.99%
EDF’s 2024 Annual results document laid out its contribution to the power plant which is “subject to some conditions, including … a share in ownership of the project of 10 to 19.99%, including a cap on financial exposure in value.”
It also requires “A return on capital expected by EDF as an investor in line with market return for this type of assets, risk allocation profile and its investment policy.”
It is understood that the reason for selecting 19.99% rather than 20% is because a company buying 20% would have to set up a subsidiary entity to take the ownership.
Another aspect of any ownership stake is a requirement to take on debt.
A UBS spokesperson told NCE: “The project would have something like £4bn of debt for every £2bn equity.”
Anti-Sizewell C groups say EDF appears to be attempting to ‘wriggle out’ of ownership
Stop Sizewell C executive director Alison Downes said: “The mention of this lower percentage stake (10%) in EDF’s results is significant.
“EDF’s leadership is clearly strapped for cash and doesn’t seem to buy its own rhetoric that replication could result in Sizewell C being built on time, significantly cheaper than Hinkley C – and neither do we.
“A reduction in EDF’s stake would leave the UK government with an even bigger costly void to fill.”
Downes also pointed out that regardless of EDF’s ownership status, the company would still likely get a construction contract since no other company has the relevant expertise.
Together Against Sizewell C spokesperson Chris Wilson said it was no surprise that “EDF hope to wriggle out of their financial commitment to the Sizewell project by suggesting a cap on their exposure and a reduction in their investment down to 10%”.
Wilson said this was not surprising given that EDF is “struggling to find investors to plug the £8bn- £13bn gap in the funding they need to finish the Hinkley Point C (HPC) build and the French state auditor’s advice to not take a final investment decision in Sizewell C until their exposure at HPC is reduced.”
“As the UK govt scrabble around for the likely £40 billion for the Sizewell C development, it’s hardly a good advert to potential investors that we now have EDF, the original promoter, hoping to reduce their exposure to as low as 10%”, Wilson said…………………………………………….. https://www.newcivilengineer.com/latest/edf-appears-to-consider-reduced-final-stake-in-sizewell-c-to-as-low-as-10-24-02-2025/
French State Spars With EDF Over Multibillion-Euro Reactor Plan

French government officials took issue with Electricite de France SA’s plan to build six nuclear plants, saying cost estimates are too broad and reactor designs not firmed up, according to people with knowledge of recent talks.
Bloomberg News, Francois de Beaupuy, Feb 14, 2025 – https://financialpost.com/pmn/business-pmn/french-state-spars-with-edf-over-multibillion-euro-reactor-plan
EDF’s board met with state representatives last week amid growing concern that the company and its suppliers are far from ready to launch a project deemed key to France’s long-term energy security. The world’s biggest nuclear-plant operator needs to prove it has a credible plan after long delays and cost overruns at other reactor developments caused debts to balloon.
Officials at the Feb. 5 meeting characterized state-owned EDF’s presentation as unconvincing on both budget and reactor design, the people said, asking not to be identified discussing private talks.
A French state auditor said last month that a final investment decision on the six reactors should be made only once their design is well advanced and funding finalized. It said the estimated bill for construction, excluding financing costs, had swelled to almost €80 billion ($84 billion) when accounting for inflation.
The criticism at last week’s presentation went both ways. EDF Chief Executive Officer Luc Remont railed against the government for enacting a finance bill that doesn’t specify tax rates on future windfall revenues, the people said. Several board members also expressed concerns about the uncertainty surrounding the level of state aid for reactor projects, the people said.
Spokespeople for EDF and the government’s shareholding agency declined to comment.
Slow progress is not only fueling tensions between EDF and the government. It also threatens to undermine preparations along the supply chain for reactor construction. In the past two years, EDF has seen US and Korean competitors make inroads in European markets as its own proposals were overlooked.
Nuclear Revival
The difficulties faced by a nuclear behemoth such as EDF may also raise questions over the speed and breadth of an atomic-power renaissance across Europe, with many countries planning new reactors to cut emissions from power generation and bolster energy security.
Back in July, EDF’s Remont expressed hope that a state support package for the six new reactors would be agreed upon by the end of 2024, paving the way for a final investment decision by the end of 2025 or early next year.
Already on the back foot, EDF must now move quickly to pin down costs and designs so that the government can work out the necessary support and seek approval from European competition authorities, the people said. The state aid needs to be fine-tuned to limit any remedies requested by Brussels, they said.
NFLAs endorse international appeal for justice over French nuclear tests
NFLA 13th Feb 2025
Sixty-five years ago (13 February 1960), the first French nuclear test was conducted in its colony of Algeria, exposing French soldiers and Indigenous Tuareg civilians to radiation.
The NFLAs have been campaigning for justice for veterans and local communities impacted by British atomic and nuclear bomb tests in Australia and the Pacific Islands, so in the spirit of solidarity we have joined UK and international partners in endorsing a similar appeal to the French and Algerian Governments over the impact of the ‘Gerboise Bleue’ (‘Blue Jerboa’) test and those which followed.
President Charles de Gaulle ordered a nuclear test in the first quarter of 1960. After a plan to explode a device in Corsica was prevented by public protests, the Nuclear Experiments Operational Group relocated to the Saharan Military Experiments Centre near Reggane in (then) French Algeria.
‘Gerboise Bleue’ (or ‘Blue Jerboa’) was the operational name for the first test of a series. The name combined a reference to one of the colours of the French flag with a rodent that resided in the Sahara Desert. On 13 February 1960, the plutonium bomb was detonated atop a 100-metre steel tower. No journalists were allowed on site, but an eyewitness account given to the French press stated that “the desert was lit up by a vast flash, followed 45 seconds later by an appreciable shock-wave” with “enormous ball of bluish fire with an orange-red centre” followed by a mushroom cloud.
Following the test, France followed the United States, the USSR and the United Kingdom as the world’s fourth nuclear armed power.
With a yield of 70 kilotons, ‘Gerboise Bleue’ was over three times more powerful than the Fat Boy plutonium bomb dropped on Nagasaki and the largest by far of the first test bombs used by any of the previous nuclear powers.
Following this test until 1966, France carried out a further three atmospheric nuclear tests and another thirteen underground tests as the ‘Gerboise’ series at this location.
The French treatment of test veterans and Indigenous communities mirrored that of the UK.
The French Ministry of the Armed Forces maintained that the radioactive effects on humans present at the site would be “weak”, and “well below annual doses.” However, test veterans said that protection gear was lacking and charged the military authorities with using them to study the effects of nuclear radiation on humans. After the later ‘Gerboise Verte’ test, soldiers were sent within 1 km of the hypocentre to practice combat exercises and to drive tanks, being subjected to high levels of radiation for three hours before being offered only a shower as a method to decontaminate.
After the tests, nuclear fallout was detected as far away as Senegal, Ivory Coast, Burkina Faso and Sudan. According to the French NGO, ACRO, Saharan dust blown northwards by strong seasonal winds to France in early 2021 carried measurable levels of radioactive caesium-137 attributable to the ‘Gerboise’ tests……………………………………………………………….. https://www.nuclearpolicy.info/news/nflas-endorse-international-appeal-for-justice-over-french-nuclear-tests/
Kansai Electric to ship more spent nuclear fuel to France

Fukui Japan Times 9th Feb 2025 https://www.japantimes.co.jp/news/2025/02/09/japan/japan-more-spent-nuke-fuel-to-france/
Kansai Electric Power is working to double the amount of spent nuclear fuel it will ship to France, increasing it by about 200 tons, informed sources said.
The move comes as Fukui Prefecture, home to several nuclear plants, urges Kansai Electric to address shrinking storage capacity for spent nuclear fuel, the sources said.
In 2023, Kansai Electric announced a plan to ship about 200 tons of the fuel from its Takahama plant in Fukui to France starting in fiscal 2027. Based on the Japanese government’s policy, the spent fuel will be used for research on technology to reprocess uranium-plutonium mixed oxide, or MOX, fuel.
At the Takahama plant, about 90% of the spent fuel storage capacity has already been used, and that amount is expected to reach the upper limit in about three years.
About 200 tons of spent fuel will be generated if the No. 1 to No. 4 reactors at the plant are operated for about three years. Kansai Electric has restarted all of its seven nuclear reactors.
The company initially planned to send spent fuel mainly to a reprocessing plant to be built in Aomori Prefecture, but the completion of the facility has been postponed.
Last September, the company notified Fukui Gov. Tatsuji Sugimoto of its intention to review the plan, and said that it would halt three reactors in the prefecture if it fails to come up with a proposal that can win the understanding of officials there by the end of fiscal 2024.
France’s top audit body questions feasibility of EDF’s nuclear plans

France’s Cour des Comptes has issued a warning about rising nuclear energy costs. It is urging state-owned utility EDF to reduce its financial risks in international projects.

France’s supreme audit institution, the Cour des Comptes, has released a report on the feasibility of the nuclear plans unveiled by the government in 2022, concluding that the industry is “far from being ready” for the challenge.
The Cour des Comptes said the plan to develop EPR2 nuclear reactors – pressurized water reactors designed by EDF and Framatome – remains unclear.
“The expected profitability of the EPR2 program remains, at this stage, unknown, especially as the financing conditions of this program have still not been determined,” the authors of the report said. “When these conditions will be clear, an additional year or more will be needed to obtain their approval by the European Commission. These delays and uncertainties, which also concern the number of power plants to be built, reduce the visibility that stakeholders in the sector need to engage in industrial projects of this magnitude and obtain financing.”

These precautions aim to prevent cost overruns similar to those seen in EDF’s Olkiluoto EPR project in Finland, the Hinkley Point plant in the United Kingdom, and the Flamanville 3 facility in France.
“EPR reactors operating in China and Finland have experienced multiple technical malfunctions in recent years, with significant financial impacts and damaging consequences for the credibility of the EPR2 program,” said Cour des Comptes. “EDF had to record in its 2023 financial report a depreciation of this asset which reduced its results by €11.5 billion ($11.77 million),” they added referring to the Hinkley Point C project, whose costs rose to GBP 33 billion ($40.6 billion), a 100% increase versus the initial estimated cost.
The court also said that a proposal to expand EDF’s Sizewell plant in the United Kingdom could be rejected if the French utility fails to reduce its financial exposure for Hinkley Point C. It warned that the industrial strategy implemented by EDF does not yet guarantee the accountability of stakeholders and noted that the incentives that are essential to the success of the EPR2 program.
“The EDF group’s strategy, which plans to continue promoting nuclear reactors internationally, should no longer make excessive equity commitments or take excessive risks in terms of profitability and operational coordination between the different projects,” the court said, noting that these financial risks may slow down the schedule of EPR2 program in France.
The report concluded that efforts to strengthen the nuclear industry remain inadequate, particularly in rebuilding skills and capacity.
Nuclear- not good vibrations in France

Renew Extra 25th Jan 2025, https://renewextraweekly.blogspot.com/2025/01/nuclear-not-good-vibrations-in-france.html
France is having problems with nuclear power. It was once the poster child for nuclear energy, which, after a rapid government funded build-up in the1980s based on standard Westinghouse Pressurised-water Reactor (PWR) designs, at one point supplied around 75% of its power, with over 50 reactors running around the country. Mass deployment of similar designs meant that there were economies of scale and given that it was a state-run programme, the government could supply low-cost funding and power could be supplied to consumers relatively cheaply.
But the plants are now getting old, and there has been a long running debate over what to do to replace them: it will be expensive given the changed energy market, with cheaper alternatives emerging. At one stage, after the Fukushima disaster in Japan in 2011, it was proposed by the socialist government to limit nuclear to supplying just 50% of French power by 2025, with renewables to be ramped up.
That began to look quite sensible when, in 2016, faults were found with the steel forgings of some of the old PWR plants. There was an extensive programme of reactor checks, with some units having to be shut down for the duration. But the industry, though chastened by stories about cover-ups, survived, and, with a new government in power led by Macron, the 50% limit was delayed. Indeed, proposals were made for significant expansion, based in part on an upgrade European Pressurised-water Reactor (EPR) design.

Macron said ‘Our energy & ecological future depends on nuclear power; our economic and industrial future depends on nuclear power; and France’s strategic future depends on nuclear power’:
The first EPR in France has been built at Flamanville on the Normandy coast, but all did not go well. It was 12 years late and four times overbudget. And new vibration problems could mean that it may not be able to run at full power. In addition, more problems (this time with stress corrosion) have been found with some of the old plants.

With at one stage, 28 of them shut down for tests and/or repairs, EDFs financial situation became increasingly weak. And, it has got worse. With, in 2024, the French government and economy also being in some disarray, it looked as if plans for more projects might have to be reconsidered, their being reports that ‘in the absence of financial commitment from the State, EDF (is) raising the possibility of halving the investments planned in the EPR2 program in 2025.’

It was the same for EDFs programme of building more EPRs in the UK- with one at Sizewell in Suffolk being proposed to follow on from the part-built one at Hinkley Point in Somerset. Indeed, the French Court of Auditors has just recommended ‘not approving a final investment decision for EDF in Sizewell C before obtaining a significant reduction in its financial exposure in Hinkley Point C’.

So what next? The somewhat beleaguered French government evidently wants the European Commission to revise EU renewable energy directive to also provide support for new nuclear! But back home, it is arguably ‘far from ready’ for a new nuclear expansion programme. And, with nuclear costs rising, the idea of treating it as ‘low risk’ compared with renewables in EU plans is being resisted. Then again EDF evidently think some new nuclear options are too risky- it has pulled out of work on its initial design for a Small Modular Reactor, so it is no longer a contender for the UK SMR competition.
What does all this mean for the UK? Well, although its overall finances are not good, up until recently, EDF has done quite well out of the UK, still running its fleet of old AGRs and its single PWR, with the UK’s funding subsidy schemes providing support for French profit-making via surcharges on UK consumers bills – in the case of the proposed new RAB scheme for Sizewell C, in advance of project completion. Indeed, some might say EDF’s exploitation of the UK has been overdone and not helpful!
Certainly, EDF’s current troubles add to the increasing level of uncertainty about Sizewell C. China had provided some backing for Hinkley, but, with there being growing concerns about security, the UK government decided that China could not be allowed to back Sizewell. So the hunt was on for new backers. However, it has proven to be hard, and with talk of the bills for these projects ballooning, allegedly to £46bn for Hinkley, the opposition lobby is getting more assertive. Hinkley Point C was originally meant to start up in 2017, but may finally get going in 2031 or so. It is a giant project, impressive in a way, but arguably not what is needed, with renewables getting so much cheaper. Same for Sizewell C- it’s getting increasingly hard to justify it.
EDF do seem to be having it tough with nuclear of late, but although the costs of the EPRs may be disputed, whatever they turn out to be, it’s far from clear if the French EPRs will be value for money. The UK has done quite well so far with renewables, which have helped it get its emissions down by a half between 1990 and 2022, compared to a 23% reduction in France, where nuclear is still predominant and renewable are, so far, less developed. Time for a change everywhere? Certainly, back in 2021, the IEA and RTE Agency in France produced a study asking if it was technically possible to integrate very high shares of renewables in large power systems like that in France. It concluded that, if coupled with adequate storage and system balancing, for renewables to supply 85-90% of power by 2050 and 100% by 2060. However, it would be expensive. But then so would continuing with nuclear, maybe more so.
