A bit of gallows humour is appropriate perhaps when entering the concrete vault of a nuclear reactor.

"Welcome to the house of Count Dracula," says health physicist Maung Zeya. "Enter at your peril."

The out-of-service Candu reactor at the Bruce Power plant appears in the dingy light like a giant mechanical beehive. The air is hot and oppressive, and a handful of repairmen are at work.

Jack Rollins, a radiation official dressed head to toe in protective gear, stands 15 metres from the reactor and points a gun that detects gamma rays. It registers 18 millirems, a unit that measures the amount of radiation absorbed.

"What you see right there has already gone right through your body," says Rollins. "It's like an X-ray."

"Now watch this," he adds, moving his arm toward the reactor and noting the numbers on his gun shooting upwards.

It's an impressive display of the staying power of radiation, particularly since its source – uranium fuel bundles – was removed from the reactor 10 years ago.

But the residual dose is well below the yearly limit for Canadian nuclear workers, allowing them significant stretches of time up close to gut and renovate reactors at the Bruce A plant on the shores of Lake Huron.

The $5.2 billion project to fully refurbish four Candu reactors by 2013 is one of the biggest construction projects in Canada. Duncan Hawthorne, president and chief executive officer of privately owned Bruce Power, says the project will make or break Canada's nuclear industry.

"It's a destiny issue for the industry," Hawthorne says. "The success of this project spawns other projects and the failure of this probably means that we wouldn't want to do it again. Everybody knows what's at stake here."

Hawthorne, who also heads the North American branch of the World Association of Nuclear Operators, believes the outcome could also impact the industry in the U.S., which uses reactors other than Candus.

"If you're trying to borrow from financiers on the back of an unsuccessful project here, what are you going to say? `Well, that was Candu and it was those Canadians that don't know what they're doing?' That's not a very easy sell," he says.

The stakes are especially high in Ontario, where the Ontario Power Authority (OPA) wants to keep almost half of the province's electricity coming from nuclear plants during the next 20 years. That means spending $26.5 billion to renovate existing plants or build new ones.

Ontario's refurbishment record leaves little room for encouragement. Renovating and restarting just two Candu reactors at Pickering A, as taxpayers know, cost publicly-owned Ontario Power Generation $2.5 billion – wildly above the initial $800 million estimate to repair all four Pickering units.

But halfway through the first part of the Bruce project – a $2.7 billion plan to renovate reactors 1 and 2 – Hawthorne remains confident.

"We're on time and on budget," he says during an interview at Bruce Power's corporate offices on the sprawling nuclear site. "That's not to say that it's plain sailing. We'll have to fight our way through it."

The Ontario Power Authority, the agency that signed the much-debated contract with Bruce on behalf of the provincial government, concurs with Hawthorne's assessment.

"Our feeling is, if they're not on target, they're pretty close," says OPA spokesperson Tim Taylor.

Bolstering confidence is the fixed-price contracts Bruce Power signed with most of the contractors. Still, critics well versed with the Pickering refurbishment fiasco roll their eyes at early talk of success.

"The Candu is a bad design – it's a nightmare. The sooner we get rid of it the better," says Frank Greening, who examined weaknesses in the Candu's pressure tubes and feeder pipes while a senior chemist at OPG.

"Refurbishing old Candus is throwing money down a black hole," he adds, describing continued faith in the technology as "Canadians being pigheaded about a Canadian product that was good at one time but now is a lemon."

Critics note that OPG permanently mothballed two Pickering A reactors in 2005 because they were not worth fixing. The other two, which cost a fortune to renovate, have performed poorly since restarting in 2003 and 2005, and were shut down all summer for maintenance.

"The test is, do the (Bruce) units come on line on budget and on time, and how long do they stay on line?" says Mark Winfield, assistant professor of environmental studies at York University. "The record so far does not inspire confidence, to put it mildly."

The Bruce nuclear site is a heavily guarded, 932-hectare complex 250 kilometres northwest of Toronto. It has two nuclear plants – Bruce A and B – each with four Candu reactors, ranging from 750 megawatts to 822 megawatts.

The six working reactors produce about 20 per cent of Ontario's electricity. When all eight are back on-line, the site's total output will be 6,200 megawatts, about 25 per cent of the province's power.

Burdened by debt, and with its nuclear program in disarray, OPG's precursor, Ontario Hydro, began shutting nuclear reactors in the late 1990s, including the four at Bruce A.

In 2001, OPG signed a long-term lease for the Bruce site with Bruce Power, a consortium today made up of uranium producer Cameco Corp., TransCanada PipeLines, the plant's two main unions, and BPC Generation Infrastructure Trust, owned by the Ontario Municipal Employees Retirement System.

By 2005, the consortium had restarted Bruce A reactors 3 and 4, a $720-million renovation project that Bruce initially thought would cost $340 million. Bruce officials blame the cost overrun, picked up wholly by the consortium, largely on security improvements imposed by the Canadian Nuclear Safety Commission after the 9/11 attacks in the U.S.

But Hawthorne makes clear there was more to it than that: "These are complicated animals to restart... restarting reactors is tough."

Also that year, Bruce Power sealed a deal with the provincial government to refurbish and restart three Bruce A reactors, and expanded it this summer to fully renovate the fourth.

Ontario's increased need for power, coupled with the Liberal policy to phase out polluting coal-burning power plants, put the government in a weak negotiating position, according to an April report on the deal by provincial Auditor General Jim McCarter.

When subsidies are factored in, such as a rent reduction for Bruce Power and the government paying for Bruce's uranium fuel, the consortium is guaranteed between 6.3 and 7.1 cents per kilowatt hour for its electricity, McCarter concluded. That's well above the 4.9 cents average for the past five years and significantly above what private-sector experts believe the future price of electricity will be, he added.

"There's a definite cost to doing this sort of deal with the private sector," McCarter says in an interview, adding that the price of Bruce electricity will also increase annually, based on inflation.

"Consumers, you've got to be prepared. Your electricity bills are going up, and they're going up by a pretty healthy amount," he says.

Hawthorne is the poster boy of a beleaguered nuclear industry. After a decade of bad press from Ontario Hydro and OPG debacles, the industry rallied around the Porsche-driving nuclear executive with a Scottish accent. A framed picture in the reception area of his office shows him cradling an unused nuclear fuel bundle in his arms.

He doesn't hesitate to lambaste what he describes as a non-existent conservation culture – "We're a backwards province and a backwards country" – and sharply criticizes Canadian governments for what he says are their abysmal investments in research and development.

He's convinced he's at the forefront of a resurgent nuclear industry, dismissing worldwide examples to the contrary — a German law to phase out nuclear plants and an Italian moratorium on building new ones, to name only two — as temporary sops to public opinion.

"I'm not for nuclear world domination, I'm just recognizing that nuclear is a very significant part of the mix," says Hawthorne, whose consortium is also studying the building of new nuclear plants on the site.

He's equally convinced Bruce can avoid OPG's flawed record of refurbishing Candus or making them work at full capacity.

He suspects a lot of OPG's troubles involved a dysfunctional workplace culture.

He describes the collective agreement Bruce Power inherited as "the thickest you would find anywhere," a result, he believes, of a workplace where "no one trust(ed) anyone."

During a general meeting with employees, Hawthorne says he announced: "If I believe what I hear, I should sack all the managers for being incompetent and sack all you guys for being lazy. I don't believe any of that, and we've got to find a way to change that culture."

In the past, the plant's performance was also badly hit by poor management and a lack of best industry practices that prolonged maintenance when reactors unexpectedly shut down, Hawthorne says. Since Bruce Power took over, technical staff has been completely retrained.

"I know it's a tough project but we're just going to go on and get it done," he says, referring to the refurbishment. "I'd rather take the chance to fail than sit here in the wings without the opportunity."

Hitachi freezes British nuclear project, books $2.8bn hit

Hitachi UK Nuclear Project Freeze reflects Horizon Nuclear Power's suspended Anglesey plant amid Brexit uncertainty, investor funding gaps, rising safety regulation costs, and a 300 billion yen write-down, impacting Britain's low-carbon electricity plans.

 

Key Points

Hitachi halted Horizon's Anglesey nuclear plant over funding and Brexit risks, recording a 300 billion yen write-down.

✅ 3 trillion yen UK nuclear project funding stalled

✅ 300 billion yen impairment wipes Horizon asset value

✅ Brexit, safety rules raised costs and investor risk

 

Japan’s Hitachi Ltd said on Thursday it has decided to freeze a 3 trillion yen ($28 billion) British nuclear power project and will consequently book a write down of 300 billion yen.

The suspension comes as Hitachi’s Horizon Nuclear Power failed to find private investors for its plans to build a plant in Anglesey, Wales, where local economic concerns have been raised, which promised to provide about 6 percent of Britain’s electricity.

“We’ve made the decision to freeze the project from the economic standpoint as a private company,” Hitachi said in a statement.

Hitachi had called on the British government to boost financial support for the project to appease investor anxiety, but turmoil over the country’s impending exit from the European Union limited the government’s capacity to compile plans, people close to the matter previously said.

Hitachi had called on the British government to boost financial support for the project to appease investor anxiety, but turmoil over the country’s impending exit from the European Union and setbacks at Hinkley Point C limited the government’s capacity to compile plans, people close to the matter previously said.

Hitachi had banked on a group of Japanese investors and the British government each taking a one-third stake in the equity portion of the project, the people said. The project would be financed one-third by equity and rest by debt.

The nuclear writedown wipes off the Horizon unit’s asset value, which stood at 296 billion yen as of September-end.

Hitachi stopped short of scrapping the northern Wales project. The company will continue to discuss with the British government on nuclear power, it said.

However, industry sources said hurdles to proceed with the project are high considering tighter safety regulations since a meltdown at Japan’s Fukushima nuclear power plant in 2011 drove up costs, even as Europe’s nuclear decline strains energy planning.

Analysts and investors viewed the suspension as an effective withdrawal and saw the decision as a positive step that has removed uncertainties for the Japanese conglomerate.

Hitachi bought Horizon in 2012 for 696 million pounds ($1.12 billion), fromE.ON and RWE as the German utilities decided to sell their joint venture following Germany’s nuclear exit after the Fukushima accident.

Hitachi’s latest decision further dims Japan’s export prospects, even as some peers pursue UK offshore wind investments to diversify.

Toshiba Corp last year scrapped its British NuGen project after its US reactor unit Westinghouse went bankrupt, while Westinghouse in China reported no major impact, and it failed to sell NuGen to South Korea’s KEPCO.

Mitsubishi Heavy Industries Ltd has effectively abandoned its Sinop nuclear project in Turkey, a person involved in the project previously told Reuters, as cost estimates had nearly doubled to around 5 trillion yen.

Electrifying: New cement makes concrete generate electricity

Cement-Based Conductive Composite transforms concrete into power by energy harvesting via triboelectric nanogenerator action, carbon fibers, and built-in capacitors, enabling net-zero buildings and self-sensing structural health monitoring from footsteps, wind, rain, and waves.

 

Key Points

A carbon fiber cement that harvests and stores energy as electricity, enabling net-zero, self-sensing concrete.

✅ Uses carbon fibers to create a conductive concrete matrix

✅ Acts as a triboelectric nanogenerator and capacitor

✅ Enables net-zero, self-sensing structural health monitoring

 

Engineers from South Korea have invented a cement-based composite that can be used in concrete to make structures that generate and store electricity through exposure to external mechanical energy sources like footsteps, wind, rain and waves, and even self-powering roads concepts.

By turning structures into power sources, the cement will crack the problem of the built environment consuming 40% of the world’s energy, complementing vehicle-to-building energy strategies across the sector, they believe.

Building users need not worry about getting electrocuted. Tests showed that a 1% volume of conductive carbon fibres in a cement mixture was enough to give the cement the desired electrical properties without compromising structural performance, complementing grid-scale vanadium flow batteries in the broader storage landscape, and the current generated was far lower than the maximum allowable level for the human body.

Researchers in mechanical and civil engineering from from Incheon National University, Kyung Hee University and Korea University developed a cement-based conductive composite (CBC) with carbon fibres that can also act as a triboelectric nanogenerator (TENG), a type of mechanical energy harvester.

They designed a lab-scale structure and a CBC-based capacitor using the developed material to test its energy harvesting and storage capabilities, similar in ambition to gravity storage approaches being scaled.

“We wanted to develop a structural energy material that could be used to build net-zero energy structures that use and produce their own electricity,” said Seung-Jung Lee, a professor in Incheon National University’s Department of Civil and Environmental Engineering, noting parallels with low-income housing microgrids in urban settings.

“Since cement is an indispensable construction material, we decided to use it with conductive fillers as the core conductive element for our CBC-TENG system,” he added.

The results of their research were published this month in the journal Nano Energy.

Apart from energy storage and harvesting, the material could also be used to design self-sensing systems that monitor the structural health and predict the remaining service life of concrete structures without any external power, which is valuable in industrial settings where hydrogen-powered port equipment is being deployed.

“Our ultimate goal was to develop materials that made the lives of people better and did not need any extra energy to save the planet. And we expect that the findings from this study can be used to expand the applicability of CBC as an all-in-one energy material for net-zero energy structures,” said Prof. Lee, pointing to emerging circular battery recycling pathways for net-zero supply chains.

Publicising the research, Incheon National University quipped: “Seems like a jolting start to a brighter and greener tomorrow!”

Opinion: Germany's drive for renewable energy is a cautionary tale

Germany Energiewende Lessons highlight climate policy tradeoffs, as renewables, wind and solar face grid constraints, coal phase-out delays, rising electricity prices, and public opposition, informing Canada on diversification, hydro, oil and gas, and balanced transition.

 

Key Points

Insights from Germany's renewable shift on costs, grid limits, and emissions to guide Canada's balanced energy policy.

✅ Evidence: high power prices, delayed coal exit, limited grid buildout

✅ Land, materials, and wildlife impacts challenge wind and solar scale-up

✅ Diversification: hydro, nuclear, gas, and storage balance reliability

 

News that Greta Thunberg is visiting Alberta should be welcomed by all Canadians.

The teenaged Swedish environmentalist has focused global attention on the climate change debate like never before. So as she tours our province, where selling renewable energy could be Alberta's next big thing, what better time for a reality check than to look at a country that is furthest ahead in already adapting steps that Greta is advocating.

That country is Germany. And it’s not a pretty sight.

Germany embraced the shift toward renewable energy before anyone else, and did so with gusto. The result?

Germany’s largest newsmagazine Der Spiegel published an article on May 3 of this year entitled “A Botched Job in Germany.” The cover showed broken wind turbines and half-finished transition towers against a dark silhouette of Berlin.

Germany’s renewable energy transition, Energiewende, is a bust. After spending and committing a total of US$580 billion to it from 2000 to 2025.

Why is that? Because it’s been a nightmare of foolish dreams based on hope rather than fact, resulting in stalled projects and dreadfully poor returns.

Last year Germany admitted it had to delay its phase-out of coal and would not meet its 2020 greenhouse gas emissions reduction commitment. Only eight per cent of the transmission lines needed to support this new approach to powering Germany have been built.

Opposition to renewables is growing due to electricity prices rising to the point they are now among the highest in the world. Wind energy projects in Germany are now facing the same opposition that pipelines are here in Canada. 

Opposition to renewables in Germany, reports Forbes, is coming from people who live in rural or suburban areas, in opposition to the “urbane, cosmopolitan elites who fetishize their solar roofs and Teslas as a sign of virtue.” Sound familiar?

So, if renewables cannot successfully power Germany, one of the richest and most technologically advanced countries in the world, who can do it better?

The biggest problem with using wind and solar power on a large scale is that the physics just don’t work. They need too much land and equipment to produce sufficient amounts of electricity.

Solar farms take 450 times more land than nuclear power plants to produce the same amount of electricity. Wind farms take 700 times more land than natural gas wells.

The amount of metal required to build these sites is enormous, requiring new mines. Wind farms are killing hundreds of endangered birds.

No amount of marketing or spin can change the poor physics of resource-intensive and land-intensive renewables.

But, wait. Isn’t Norway, Greta’s neighbour, dumping its energy investments and moving into alternative energy like wind farms in a big way?

No, not really. Fact is only 0.8 per cent of Norway’s power comes from wind turbines. The country is blessed with a lot of hydroelectric power, but that’s a historical strength owing to the country’s geography, nothing new.

And yet we’re being told the US$1-trillion Oslo-based Government Pension Fund Global is moving out of the energy sector to instead invest in wind, solar and other alternative energy technologies. According to 350.org activist Nicolo Wojewoda this is “yet another nail in the coffin of the coal, oil, and gas industry.”

Well, no.

Norway’s pension fund is indeed investing in new energy forms, but not while pulling out of traditional investments in oil and gas. Rather, as any prudent fund manager will, they are diversifying by making modest investments in emerging industries such as Alberta's renewable energy surge that will likely pay off down the road while maintaining existing investments, spreading their investments around to reduce risk. Unfortunately for climate alarmists, the reality is far more nuanced and not nearly as explosive as they’d like us to think.

Yet, that’s enough for them to spin this tale to argue Canada should exit oil and gas investment and put all of our money into wind and solar, even as Canada remains a solar power laggard according to experts.

That is not to say renewable energy projects like wind and solar don’t have a place. They do, and we must continue to innovate and research lower-polluting ways to power our societies on the path to zero-emissions electricity by 2035 in Canada.

But like it actually is in Norway, investment in renewables should supplement — not replace — fossil fuel energy systems if we aim for zero-emission electricity in Canada by 2035 without undermining reliability. We need both.

And that’s the message that Greta should hear when she arrives in Canada.

Putting Africa on the path to universal electricity access

West and Central Africa Electricity Access hinges on utility reform, renewable energy, off-grid solar, mini-grids, battery storage, and regional grid integration, lowering costs, curbing energy poverty, and advancing SDG7 with sustainable, reliable power solutions.

 

Key Points

Expanding reliable power via renewables, grid trade, and off-grid systems to cut energy poverty and unlock inclusive growth.

✅ Utility reform lowers costs and improves service reliability

✅ Regional grid integration enables clean, least-cost power trade

✅ Off-grid solar and mini-grids electrify remote communities

 

As commodity prices soar and leaders around the world worry about energy shortages and prices of gasoline at the pump, millions of people in Africa still lack access to electricity.  One-half of the people on the continent cannot turn on a fan when temperatures go up, can’t keep food cool, or simply turn the lights on. This energy access crisis must be addressed urgently.

In West and Central Africa, only three countries are on track to give every one of their people access to electricity by 2030. At this slow pace, 263 million people in the region will be left without electricity in ten years.  West Africa has one of the lowest rates of electricity access in the world; only about 42% of the total population, and 8% of rural residents, have access to electricity.

These numbers, some far too big, others far too small, have grave consequences. Electricity is an important step toward enhancing people’s opportunities and choices. Access is key to boosting economic activity and contributes to improving human capital, which, in turn, is an investment in a country’s potential.  

Without electricity, children can’t do their schoolwork at night. Businesspeople can’t get information on markets or trade with each other. Worse, as the COVID-19 pandemic has shown so starkly, limited access to energy constrains hospital and emergency services, further endangering patients and spoiling precious medicine.  

What will it take to power West and Central Africa?  
As the African continent recovers from COVID-19 impacts, now is the critical time to accelerate progress towards universal energy access to drive the region’s economic transformation, promote socio-economic inclusion, and unlock human capital growth. Without reliable access to electricity, the holes in a country’s social fabric can grow bigger, those without access growing disenchanted with inequality.  

Tackling the Africa region’s energy access crisis requires four bold approaches. 

First, this involves making utilities financially viable. Many power providers in the region are cash-strapped, operate dilapidated and aging generation fleet and infrastructure. Therefore, they can’t deliver reliable and affordable electricity to their customers, let alone deliver electricity to those that currently must rely on inadequate alternatives to electricity. Overall, fewer than half of the utilities in Sub-Saharan Africa recover their operating costs, resulting in GDP losses as high as four percent in some countries.

Improving the performance of national utilities and greening their power generation mix is a prerequisite to lowering the costs of supply, thus expanding electricity access to those currently unelectrified, usually lower-income and often remote households. 

In that effort — and this a critical second point — West and Central African countries need to look beyond their borders and further integrate their national utilities and grids to other systems in the region. The region has an abundance of affordable clean energy sources — hydropower in Guinea, Mali, and Cote d’Ivoire; high solar irradiation in the Sahel — but the regional energy market is fragmented. 

Without efficient regional trade, many countries are highly dependent on one or two energy resources and heavily reliant on inefficient, polluting generation sources, requiring fuel imports linked to volatile international oil prices.

The vision of an integrated regional power market in countries of the Economic Community of West African States (ECOWAS) is coming a step closer to reality thanks to an ambitious program of cross-border interconnection projects. If countries take full advantage of this grid, the share of the region’s electricity consumption traded across borders would more than double from 8 percent today to about 17 percent by 2030. Overall, regional power trade could lower the lifecycle cost of West Africa’s power generation system by about 10 percent and provide greener energy by 2030. 

Third, electrification efforts need to be open to private sector investments and innovations, such as renewables like solar energy and battery storage, which have made a tremendous impact in enabling access for millions of poor and underserved households.  Specifically, off-grid solar systems and mini-grids have become a proven reliable way to provide affordable modern electricity services, powering homes in rural communities, healthcare facilities, and schools.

Burkina Faso, which enjoys one of the best solar radiation conditions in the region, is a successful example of leveraging the transformative impact of solar energy and battery storage. With support from the World Bank, the country is deploying solar energy to power its national grid, as well as mini-grids and individual household systems. Solar power with battery storage is competitive in Burkina Faso compared to other technologies and its government was successful in attracting private sector investments to support this technology.

Last, achieving universal electricity access will involve significant commitment from political leaders, especially developing policies and regulations that can attract high-quality investments.  

A significant step in that direction was achieved at the World Bank’s 2020 Annual Meetings with a commitment to set up the Powering Transformation Platform in each African country. Through the platform, each government will set their country-specific vision, goals and metrics, track progress, and explore and exchange innovative ideas and emerging best practices according to their own national energy needs and plans. 

This platform will bring together the elements needed to bring electricity to all in West and Central Africa and help attract new financing.

Over the last 3 years, the World Bank has doubled its investments to increase electricity access rates in Central and West Africa.  We have committed more than $7.8 billion to support 40 electricity access programs, of which more than half directly support new electricity connections. These operations are expected to provide access to 16 million people. The aim is to increase electricity access rates in West and Central Africa from 50 percent today to 64 percent by 2026.

However, World Bank’s financing alone is not enough. Our estimates show that nearly $20 billion are required for universal electrification across Sub-Saharan Africa, aligning with calls to quadruple power investment to meet demand, with about $10 billion annually needed for West and Central Africa. 

Closing the funding gap will require mobilizing traditional and new partners, especially the private sector, which is willing to invest if enabling conditions are in place, as well as philanthropic capital, that can fill in the space in areas not yet commercially attractive. The World Bank is ready to play a catalytical role in leveraging new investments. 

This is vital as less than a decade remains to reach the 2030 SDG7 goal of ensuring electricity for all through affordable, reliable, and modern energy services. As headlines worldwide focus on soaring energy prices in the developed world, we cannot lose sight of the vast populations in Africa that still cannot access basic energy services. This is the true global energy crisis.

Nuclear helps Belgium increase electricity exports in 2019

Belgium Energy Mix 2019 shows strong nuclear output, rising offshore wind, net electricity exports, and robust interconnections, per Elia, as the nuclear phaseout drives 3.9GW new capacity needs after improved reactor availability.

 

Key Points

High nuclear share, offshore wind, net exports, interconnections; 3.9GW capacity needed amid nuclear phaseout.

✅ Nuclear supplied 48.8% of generation in 2019.

✅ Net exporter: 1.8 TWh, aided by interconnections.

✅ Elia projects 3.9GW new capacity for phaseout.

 

Belgium's electricity transmission system operator, Elia, said that the major trends in 2019 were a steady increase in (mainly offshore) renewable power generation, illustrated by EU wind and solar records across the bloc, better availability of nuclear-generating facilities and an increase in electricity exports.

In 2019, 48.8% of the power generated in Belgium came from nuclear plants. This was in line with the total for 2017 (50%) and significantly more than in 2018 (31.2%) when several reactors were unavailable amid stunted hydro and nuclear output in Europe as well.

Belgium exported more electricity in 2019, as neighbors like Germany saw renewables overtake coal and nuclear generation, with net exports of 1.8TWh (2.1% of the energy mix), in contrast to 2018 when Belgium imported 17.5TWh (20%).

Elia said this “should be viewed in its wider context, of declining nuclear capacity in Europe and regional market shifts, against the backdrop of an increasingly Europeanised market, and can be explained primarily by the good availability of Belgium's generating facilities (especially its nuclear power stations).”

The development of interconnections was also a key factor in the circulation of these electricity flows, as seen with Irish grid price spikes highlighting regional stress, Elia noted.

“Belgium had not been a net exporter of electricity for almost 10 years, the last time being in 2009 and 2010, when total net exports represented 2.8% and 0.2% respectively of Belgium’s energy mix,” it said.

Belgian has seven nuclear reactors – three at Tihange near Liege and four at Doel near Antwerp – and, regionally, nuclear-powered France faces outage risks that influence cross-border reliability.

In 2003, Belgium decided to phase out nuclear power and passed a law to that effect, with neighbors like Germany navigating a balancing act during their energy transition, which was reaffirmed in 2015 and 2018.

A commission appointed to assess the impact of the nuclear phaseout is scheduled to be completed in 2025 but has yet to report any findings.

Elia estimates that some 3.9GW of new power generating capacity will be needed to compensate for Belgium's nuclear phaseout.

Global: Nuclear power: what the ‘green industrial revolution’ means for the next three waves of reactors

UK Nuclear Energy Ten Point Plan outlines support for large reactors, SMRs, and AMRs, funding Sizewell C, hydrogen production, and industrial heat to reach net zero, decarbonize transport and heating, and expand clean electricity capacity.

 

Key Points

A UK plan backing large, small, and advanced reactors to drive net zero via clean power, hydrogen, and industrial heat.

✅ Funds large plants (e.g., Sizewell C) under value-for-money models

✅ Invests in SMRs for factory-built, modular, lower-cost deployment

✅ Backs AMRs for high-temperature heat, hydrogen, and industry

 

The UK government has just announced its “Ten Point Plan for a Green Industrial Revolution”, in which it lays out a vision for the future of energy, transport and nature in the UK. As researchers into nuclear energy, my colleagues and I were pleased to see the plan is rather favourable to new nuclear power.

It follows the advice from the UK’s Nuclear Innovation and Research Advisory Board, pledging to pursue large power plants based on current technology, and following that up with financial support for two further waves of reactor technology (“small” and “advanced” modular reactors).

This support is an important part of the plan to reach net-zero emissions by 2050, as in the years to come nuclear power will be crucial to decarbonising not just the electricity supply but the whole of society.

This chart helps illustrate the extent of the challenge faced:

Electricity generation is only responsible for a small percentage of UK emissions. William Bodel. Data: UK Climate Change Committee

Efforts to reduce emissions have so far only partially decarbonised the electricity generation sector. Reaching net zero will require immense effort to also decarbonise heating, transport, as well as shipping and aviation. The plan proposes investment in hydrogen production and electric vehicles to address these three areas – which will require, as advocates of nuclear beyond electricity argue, a lot more energy generation.

Nuclear is well-placed to provide a proportion of this energy. Reaching net zero will be a huge challenge, and industry leaders warn it may be unachievable without nuclear energy. So here’s what the announcement means for the three “waves” of nuclear power.

Who will pay for it?
But first a word on financing. To understand the strategy, it is important to realise that the reason there has been so little new activity in the UK’s nuclear sector since the 1990s is due to difficulty in financing. Nuclear plants are cheap to fuel and operate and last for a long time. In theory, this offsets the enormous upfront capital cost, and results in competitively priced electricity overall.

But ever since the electricity sector was privatised, governments have been averse to spending public money on power plants. This, combined with resulting higher borrowing costs and cheaper alternatives (gas power), has meant that in practice nuclear has been sidelined for two decades. While climate change offers an opportunity for a revival, these financial concerns remain.

Large nuclear
Hinkley Point C is a large nuclear station currently under construction in Somerset, England. The project is well-advanced, with its first reactor installed and due to come online in the middle of this decade. While the plant will provide around 7% of current UK electricity demand, its agreed electricity price is relatively expensive.

Under construction: Hinkley Point C. Ben Birchall/PA

The government’s new plan states: “We are pursuing large-scale new nuclear projects, subject to value-for-money.” This is likely a reference to the proposed Sizewell C in Suffolk, on which a final decision is expected soon. Sizewell C would be a copy of the Hinkley plant – building follow-up identical reactors achieves capital cost reductions, and setbacks at Hinkley Point C have sharpened delivery focus as an alternative funding model will likely be implemented to reduce financing costs.

Other potential nuclear sites such as Wylfa and Moorside (shelved in 2018 and 2019 respectively for financial reasons) are also not mentioned, their futures presumably also covered by the “subject to value-for-money” clause.

Small nuclear
The next generation of nuclear technology, with various designs under development worldwide are smaller, cheaper, safer Small Modular Reactors (SMRs), such as the Rolls Royce “UK SMR”.

Reactors small enough to be manufactured in factories and delivered as modules can be assembled on site in much shorter times than larger designs, which in contrast are constructed mostly on site. In so doing, the capital costs per unit (and therefore borrowing costs) could be significantly lower than current new-builds.

The plan states “up to £215 million” will be made available for SMRs, Phase 2 of which will begin next year, with anticipated delivery of units around a decade from now.

Advanced nuclear
The third proposed wave of nuclear will be the Advanced Modular Reactors (AMRs). These are truly innovative technologies, with a wide range of benefits over present designs and, like the small reactors, they are modular to keep prices down.

Crucially, advanced reactors operate at much higher temperatures – some promise in excess of 750°C compared to around 300°C in current reactors. This is important as that heat can be used in industrial processes which require high temperatures, such as ceramics, which they currently get through electrical heating or by directly burning fossil fuels. If those ceramics factories could instead use heat from AMRs placed nearby, it would reduce CO₂ emissions from industry (see chart above).

High temperatures can also be used to generate hydrogen, which the government’s plan recognises has the potential to replace natural gas in heating and eventually also in pioneering zero-emission vehicles, ships and aircraft. Most hydrogen is produced from natural gas, with the downside of generating CO₂ in the process. A carbon-free alternative involves splitting water using electricity (electrolysis), though this is rather inefficient. More efficient methods which require high temperatures are yet to achieve commercialisation, however if realised, this would make high temperature nuclear particularly useful.

The government is committing “up to £170 million” for AMR research, and specifies a target for a demonstrator plant by the early 2030s. The most promising candidate is likely a High Temperature Gas-cooled Reactor which is possible, if ambitious, over this timescale. The Chinese currently lead the way with this technology, and their version of this reactor concept is expected soon.

In summary, the plan is welcome news for the nuclear sector, even as Europe loses nuclear capacity across the continent. While it lacks some specifics, these may be detailed in the government’s upcoming Energy White Paper. The advice to government has been acknowledged, and the sums of money mentioned throughout are significant enough to really get started on the necessary research and development.

Achieving net zero is a vast undertaking, and recognising that nuclear can make a substantial contribution if properly supported is an important step towards hitting that target.
