Canada’s small nuclear reactor project is looking like just a pipe-dream.

Globe Climate: Canada wants nuclear to power the future. But how? SIERRA BEIN Matthew McClearn is an investigative reporter and data journalist with The Globe. For this week’sdeeper dive, he talks about Canada’s nuclear ambitions. Globe and Mail, 19 July 21

Senior government officials, notably federal Natural Resources Minister Seamus O’Regan, say small modular reactors (SMRs) will help Canada achieve net-zero carbon emissions by mid-century. There’s just one problem: it’s not clear yet whether any will be built.

To be sure, many promises made by SMR vendors seem compelling. By taking advantage of factory-style mass production, they’re supposed to be far cheaper than previous generations of reactors, which tended to be massive and prone to cost overruns. They’d also be easier to deploy…….. 

A mad scramble to deliver on these promises is now underway. Ontario Power Generation—by far Canada’s most experienced nuclear station operator—plans to select a vendor to build a SMR at its Darlington Station by 2028. Further out, Saskatchewan is considering whether to order its own SMRs to replace coal-fired plants.

Accomplishing all that would silence numerous critics and naysayers. But as I explain in my most recent story, history is littered with reactors that failed to live up to their promises.   . Many SMR vendors are very early-stage companies which face years of grueling, expensive R&D work to advance their designs to the point they could actually be built. And they’re competing against renewable technologies including wind and solar, which utilities can purchase and deploy today. It may be premature to count on SMRs to help meet Canada’s emissions targets.   https://www.theglobeandmail.com/canada/article-globe-climate-canada-wants-nuclear-to-power-the-future-but-how/https://www.theglobeandmail.com/canada/article-globe-climate-canada-wants-nuclear-to-power-the-future-but-how/

Small Nuclear Reactors are all the hype. But here’s the reality

promoting a dizzying assortment of  next-generation models that have collectively been dubbed “small modular reactors” (SMRs).……..

The real challenge “is answering all the safety questions that any good regulator would ask: ‘How will this behave if there’s an earthquake or fire? What happens if there’s a complete blackout? What happens if this component fails?’ ” Answering such questions requires an intensive research program and countless hours of laboratory work, which can take decades. There’s no guarantee the answers will be favourable.

Governments, utilities and the nuclear industry hope small modular reactors will power Canada’s future. Can they actually build one?  The Globe and Mail MATTHEW MCCLEARN, JULY 17, 2021  Ontario Power Generation plans to make a decision this year that might determine the future of Canada’s nuclear industry.The utility, by far Canada’s largest nuclear power producer, promises to select a design for a 300-megawatt reactor it proposes to build at its Darlington Nuclear Generating Station by 2028. The estimated price tag: up to $3-billion. It would be the first new reactor built on Canadian soil in well over three decades. OPG won’t make that decision alone, because it’s intended to be the first of many reactors of the same design built across the country.Canada’s nuclear industry desperately needs a next act…..  With a supply chain of more than 200 companies covering everything from uranium mining, to operating power plants, to decommissioning them, Canada is considered a Tier 1 nuclear country.

But lately, this machine has been devoted to squeezing more life out of old CANDU units, largely through Ontario’s $26-billion plan to refurbish its Darlington station, east of Toronto, and the Bruce Power complex, on Lake Huron. The industry has few, if any, exciting new products for sale……
but  renewable forms of generation – hydro, wind, solar and biomass – have become preferred tools for decarbonizing electricity grids. And utilities can buy inexpensive wind turbines and solar panels today.

Seeking to catch up, dozens of nuclear vendors sprung up just in the past few years, promoting a dizzying assortment of  next-generation models that have collectively been dubbed “small modular reactors” (SMRs)………

U.S. President Joe Biden and U.K. Prime Minister Boris Johnson have also indicated they will also support SMR development, as have some prominent investors, notably Bill Gates.

Here’s the reality: Most SMRs exist only as conceptual designs and are not yet licensed for construction anywhere.

The promised assembly lines that would churn them out like clockwork don’t exist

Here’s the reality: Most SMRs exist only as conceptual designs and are not yet licensed for construction anywhere. (The international law firm White & Case says the only contemporary SMR in existence is located on a vessel anchored off Russia’s Arctic coast. According to reports, construction of China’s first SMR recently commenced on the southern island of Hainan.) The promised assembly lines that would churn them out like clockwork don’t exist; many vendors are early-stage companies with hardly any revenues.
To change this, the federal government will probably have to open wide the taxpayer’s wallet. And the industry must move quickly from bold marketing claims to commercially viable products

OLD IDEAS, NEW PACKAGESMR is a marketing term, rather than a technical one, reflecting the industry’s aspirations rather than what it can deliver today.In Canada, SMR has come to describe reactors that generate 300 megawatts or less. That isn’t exactly small – it’s enough to power a small city – but for comparison’s sake, Ontario’s largest current reactors generate around 900 megawatts. Some proposed SMRs would produce just a few megawatts. The industry pitches them for remote Indigenous communities, industrial use (at mines, for instance) and tiny island nations.Small reactors aren’t new. They’ve been used in icebreakers, submarines and aircraft carriers. And many SMRs are based on concepts contemplated as long ago as the 1950s.

Oakville, Ont.-based Terrestrial Energy Inc., one of OPG’s potential partners, intends to use molten salt, rather than water, as a coolant. The company says its technology is a “game-changer”: The Integral Molten Salt Reactor (IMSR) would operate at much higher temperatures (about 700 C) than conventional reactors (about 300 C)….

As for the “modular” part, the notion is that SMRs would be mass-produced on assembly lines and shipped to where they’re needed, rather than custom-built onsite. This plug-and-play approach is intended to reduce purchase costs and accelerate deployment…………….

SMRs appeal to certain nationalist impulses as well: Canada is, after all, the world’s second-largest uranium producer.
…… The industry has made limited progress in addressing wastes from decades-old reactors; it’s unclear how novel detritus from SMRs might be handled. Perhaps most damagingly of all, reactors have earned a reputation for being overpriced relative to other forms of generation, and oftenbeleaguered by massive delays and cost overruns.

SMR GAME PLAN

The nuclear industry’s plan to reverse its flagging fortunes begins at Darlington. OPG announced late last year it was working with three SMR developers on preliminary design and engineering work: North Carolina-based GE Hitachi Nuclear Energy, Terrestrial Energy and X-energy. It promises to select a winner by year’s end….
Naturally, of course, no SMR developer aspires to be a one-hit wonder. So next up: Persuade Saskatchewan to build a fleet of the same reactors……….. Winning Saskatchewan would be a major coup: Jurisdictions that go nuclear tend to stay nuclear for decades. ……  quandary remains: Prospective SMR buyers such as SaskPower can only look at conceptual designs. “There’s been some small demonstration units built, but nothing of the size that we would expect to see in operational terms,” Mr. Morgan said.

……... NUCLEAR GHOSTS Twenty years ago, Canada’s nuclear industry staked its future on updating the venerable CANDU design. Atomic Energy of Canada Ltd. (AECL), the
 Crown corporation that pioneered it, talked up the Enhanced CANDU 6, CANDU 9 and Advanced CANDU Reactor (ACR) as safer, faster to construct, cheaper and better than previous models. The federal government pumped untold sums into their development.None were licensed. None were ordered. None were built.

In 2011, the federal government sold AECL’s reactor business to SNC-Lavalin for a paltry $15-million. After six decades of development, and dozens of bona fide reactors built and operated in seven countries, the CANDU had become nearly worthless.

The proposed site for OPG’s first SMR, next to the existing Darlington Station, is an artifact of that era. In 2006, OPG began preparing to build up to four reactors at the same location. AECL’s Enhanced CANDU 6 and the ACR 1000 were candidates.But the project was derailed in late 2013 when the Ontario government asked OPG to stand down, essentially because the province no longer needed the power. The viability of those “next-generation” CANDUs, however, was never clear.

It’s relatively easy to sketch a reactor design on the back of a napkin, or create promotional videos and brochures with snazzy renderings. Professor M.V. Ramana, of the University of British Columbia’s Liu Institute for Global Issues, says a few graduate students can develop a conceptual design for a few hundred thousand dollars.

But it’s quite another matter to advance a design to the point of actually building it. The real challenge, Prof. Ramana said, “is answering all the safety questions that any good regulator would ask: ‘How will this behave if there’s an earthquake or fire? What happens if there’s a complete blackout? What happens if this component fails?’ ” Answering such questions requires an intensive research program and countless hours of laboratory work, which can take decades. There’s no guarantee the answers will be favourable.

……………  Even a mature design isn’t enough. Just as Ford wouldn’t build an assembly line for the Mustang Mach-E if it thought it could sell only a handful, SMR vendors need assurances they’ll receive enough orders to justify mass production. It’s unclear how many orders would be sufficient, but published estimates have ranged from as low as 30 to well into the hundreds.

……… Prof. Ramana said many of the earliest power reactors met the modern definition of SMRs. But their diminutive size was rarely a virtue: It meant they couldn’t take advantage of economies of scale, resulting in high costs per unit of electricity generated, not to mention disproportionately greater volumes of radioactive waste. Many were shut down early.

“The lesson that we learned from some of these experiences is that designs that might seem captivating on paper might not actually work so well in real life,” Prof. Ramana said. “SMRs are not going to be economical. You can see that from the outset.”

………………. FEDERAL SUPPORT – THE CRUCIAL INGREDIENT. In contrast with the CANDU, the nuclear industry promises SMRs will be funded largely by the private sector. Many observers are skeptical. “Without government programs and financial support promoting SMRs, industry alone is unlikely to invest in the high up-front costs,” opined lawyers at Stikeman Elliott in a recent commentary.
Nor are non-nuclear provinces likely to make the leap alone. Mr. Morgan confirmed Saskatchewan seeks federal support to deploy SMRs, although the form of that support has yet to be determined.

For several years, federal and provincial government officials have signalled they want Canada to be one of the earliest adopters of SMRs. They’ve partnered with industry to produce road maps for making that happen. The governments of Ontario, New Brunswick, Saskatchewan and Alberta have agreed to collaborate on advancing SMRs. Mr. O’Regan, the federal Natural Resources Minister, has fully embraced the industry’s claim that Canada’s clean-energy transition cannot succeed without them,

So far, however, such pronouncements haven’t translated into generous subsidies. The federal government has channelled just meagre amounts of funding to SMRs, such as $20-million last October toward development of Terrestrial’s IMSR, and $50.5-million to New Brunswick-based Moltex Energy in March.
The latest federal budget didn’t mention SMRs. Nevertheless, studying its fine print, lawyers at McCarthy Tétrault LLP noticed what they described as “exciting policy levers.” They pointed, for example, to an income tax break of up to 50 per cent for manufacturers of zero-emission technologies. There was also $1-billion offered for clean tech projects “where there is a perceived lack of patient capital or ability to scale up because of the size of the Canadian market.” SMR vendors could capitalize on such programs, the lawyers concluded, depending on how they’re implemented.

Meanwhile, SMR vendors seek relaxed safety requirements that could make SMRs more cost-competitive. 
……It’s unclear to what extent the Canadian Nuclear Safety Commission (CNSC) will acquiesce………….
Obtaining a licence typically takes a few years. “Experience has shown that it will be dramatically affected by the [proponent’s] capability of submitting adequate and complete information on day one,” Mr. Carrier said. Only one SMR has so far commenced a full licensing review: Ottawa-based Global First Power Ltd. submitted documentation for its Micro Modular Reactor in March.
The Union of Concerned Scientists, a long-time opponent of nuclear power, released a study in March which concluded that SMR designs, including molten salt reactors, are no safer than previous designs. It therefore urged regulators to maintain current requirements.

“The intense scrutiny, from policy makers and the public – given the safety and security angle combined with a nascent technology – will likely cause delays and conflicts” for SMR developers, lawyers from global law firm White & Case predicted in a recent commentary.

In short, SMRs’ future depends to a large extent on vendors delivering hard proof supporting their most ambitious promises about safety, efficiency, cost and other matters……..   a late arrival by SMRs could consign them to irrelevance. And right now, many observers regard them as too speculative to factor into forecasts. The federal government’s own Canada Energy Regulator projects the amount of power generated by nuclear reactors in Canada will continue on a declining trend.

Dennis Langren is a regulatory lawyer with Stikeman Elliott. He says the earliest deployments of SMRs in Canada are at least a decade off
Paris-based Mycle Schneider Consulting has reviewed the status of global SMR development three times since 2015. In the firm’s most recent review, published in September, 2020, it found little had changed over the period.

“Overall, there are few signs that would hint at a major breakthrough for SMRs, either with regard to the technology or with regard to the commercial side,” the firm observed. “Delays, poor economics, and the increased availability of low-carbon alternatives at rapidly decreasing cost plague these technologies as well, and there is no need to wait with bated breath for SMRs to be deployed.”

Ralph Torrie is a partner at Torrie Smith Associates, an energy and environmental consultancy. He says he’s focused on power generation options that can be built this decade to address a warming climate – a criterion that, in his view, disqualifies SMRs.“They’re a long way off.”  theglobeandmail.com/business/article-governments-utilities-and-the-nuclear-industry-hope-small-modular/#:~:text=The%20utility%2C%20by%20far%20Canada’s,Nuclear%20Generating%20Station%20by%202028.–

American experts warn Trudeau that Moltex small nuclear reactors are likely to prove a nightmare for Canada

The critics contend that SMRs are costly, unproven and creators of toxic waste of their own. From a practical point of view, it is hard to make the case that SMRs will be crucial in the battle against climate change, since they won’t come off the drawing board for years, if ever. Former Green Party leader Elizabeth May says that opting for experimental SMRs is just another way of delaying real action on global warming.

US Experts to Trudeau: Your Nuclear Dream May Turn Nightmare   https://thetyee.ca/Analysis/2021/05/26/US-Experts-Trudeau-Your-Nuclear-Dream-May-Turn-Nightmare/?utm_source=daily&utm_medium=email&utm_campaign=260521

Rethink backing the Moltex reactor, urge nine non-proliferation heavyweights.

Michael Harris TheTyee.ca, 6 May 21, A blue-ribbon group of American nuclear non-proliferation experts warns that Canada’s investment in new nuclear technology could lead to the spread of nuclear weapons and new threats to the environment.

“We write as U.S. non-proliferation experts and former government officials and advisors with related responsibilities to express our concern about your government’s financial support of Moltex — a startup company that proposes to reprocess CANDU spent fuel to recover its contained plutonium for use in molten-salt-cooled reactors.”

The warning came in the form of an open letter to Prime Minister Justin Trudeau that was delivered on Tuesday and signed by the nine experts.

The group is spearheaded by Frank von Hippel, professor and senior research physicist at Princeton University; it includes Matthew Bunn, the Schlesinger professor of the practise of energy, national security, and foreign policy at the Harvard Kennedy School; and Thomas Countryman, former U.S. assistant secretary of state for non-proliferation.

“We understand your government’s motivation to support nuclear power and to reduce fossil fuel use but saving the world from climate disaster need not be in conflict with saving it from nuclear weapons. Also, like other reprocessing efforts, Moltex, even in the R&D stage, would create a costly legacy of contaminated facilities and radioactive waste streams, and require substantial additional government funding for cleanup and stabilization prior to disposal,” they wrote.

Rory O’Sullivan, CEO of Moltex North America painted a very different picture of his company’s experimental technology in an interview with World Nuclear News: “We are working to develop a technology that uses the fuel from the first generation of nuclear power to the next. This reduces the challenges associated with spent nuclear fuel, while expanding nuclear power to help Canada achieve its climate change objectives.”

The Trudeau government has invested $50.5 million in Moltex, and backs the company’s plan to build a 300 MW molten salt reactor in New Brunswick on the Bay of Fundy. Theoretically, it would then reprocess spent fuel from the Point Lepreau nuclear plant, which is set to be decommissioned in 2040.

The Moltex reactor belongs to a class of nuclear power plants termed small modular reactors or SMRs that generate small amounts of electricity in comparison with typical CANDU reactors.

Natural Resources Minister Seamus O’Regan has said that Canada can’t get to net-zero carbon emissions by 2050 without nuclear as part of the equation, along with renewables.

Despite marketing its roll of the dice on Moltex as part of its war on climate change, Ottawa isn’t getting much love from environmentalists, or many other people. Three federal political parties, the NDP, the Bloc and the Greens; the Green Budget Coalition; and the Canadian Environmental Law Association all oppose the federal investment in small modular reactors. University of British Columbia professor of public policy and global affairs M.V. Ramana has levelled criticisms in these pages as well.

The critics contend that SMRs are costly, unproven and creators of toxic waste of their own. From a practical point of view, it is hard to make the case that SMRs will be crucial in the battle against climate change, since they won’t come off the drawing board for years, if ever. Former Green Party leader Elizabeth May says that opting for experimental SMRs is just another way of delaying real action on global warming.

One who has closely followed and opposes the two experimental SMR reactors planned for New Brunswick, the ARC-100 and the Moltex SSR, is Dr. Susan O’Donnell, an adjunct professor of sociology at the University of New Brunswick. O’Donnell is also the primary investigator of Raven, a research team based at the university dedicated to highlighting rural environmental issues in the province.

O’Donnell points out that Moltex has never built a nuclear reactor before. In fact, only two molten salt reactors have ever been built — 50 years ago. Neither of them produced electricity. One of them lasted four years before shutting down, the other, just 100 hours.

On the environmental side, O’Donnell says that SMR pollution or a serious failure could lead to “disasters and no-go zones.”

On the non-proliferation front, she denounces the plan to broadly “export” the Moltex technology, assuming it ever gets up and running.

“What we have learned from Canada’s role in making India a nuclear power is that one of the dangers of the Moltex proposal is its plan to export the technology. We’re exporting bomb-making capacity,” she told The Tyee.

O’Donnell has pushed for public consultations to help develop a national radioactive waste policy. Last Aug. 13, she made an offer to the federal minister of natural resources to have the Raven project organize such a public consultation in New Brunswick. It would be online because of the pandemic, in both official languages, and would include Indigenous nations and rural communities. Minister O’Regan responded two months later, on Oct. 30, turning her down.

“Strangely, he cited the pandemic, even though our offer clearly stated the consultation would be virtual,” the professor said.

O’Donnell’s take on the Moltex project is backed up by Allison Macfarlane, former chair of the U.S. Nuclear Regulatory Commission. The specialist in the storage of nuclear waste told the CBC in January that the molten salt technology is totally unproven with respect to viability, costs and storage risks.

“Nobody knows what the numbers are, and anybody who gives you numbers is selling you a bridge to nowhere…. Nobody’s been able to answer my questions yet on what all those wastes are, and how much of them there are, and how heat-producing they are and what their compositions are,” Macfarlane said. She is now the director of the School of Public Policy and Global Affairs at UBC.

But the Trudeau government does have allies at the provincial level for its nuclear ambitions. The governments of New Brunswick, Ontario, Saskatchewan and Alberta have all signed a memorandum of understanding to develop SMRs, which means promoting them.

They are excited about the promises by Moltex that it will be able to produce clean energy at a low cost by recycling something that everyone wants to get rid of — the three million spent fuel bundles in Canada that the government still doesn’t know how to dispose of safely and permanently.

The U.S. experts made clear to the PM in their letter that they are not convinced by the company’s assertions. They want the Trudeau government to convene a high-level review of both the non-proliferation and environmental implications of Moltex’s reprocessing proposal. Key to that proposal is including “independent international experts,” before Ottawa makes any further investments in support of the Moltex proposal.

The earliest projects to reprocess nuclear waste extracted plutonium to make nuclear weapons. The letter signees worry Canada’s new generation of reactors will afford the same opportunity to anyone who buys them.

“Our main concern is that, by backing spent-fuel reprocessing and plutonium extraction, the government of Canada will undermine the global nuclear weapons non-proliferation regime that Canada has done so much to strengthen. Canada is a founding member of the Nuclear Suppliers Group, which was established in 1974 in response to India’s misuse of a Canada-supplied research reactor and U.S.-supplied reprocessing technology to acquire the plutonium needed for its first nuclear weapons.”

The reprocessing of nuclear waste was “indefinitely deferred” in the United States by president Jimmy Carter in 1977 after India tested its first nuclear weapon. At the time, the Americans discovered that several other countries including Brazil, Pakistan, South Korea and Taiwan were all surreptitiously headed down the same nuclear weapons path that India had taken. Of that group, only Pakistan managed to get the bomb.

The U.S. experts who signed the letter to Trudeau also rejected the claim by Moltex that by using spent fuel from older Canadian CANDU reactors, its reactor would reduce the long-term risk from a deep underground radioactive waste repository.

The Trudeau government promised it would base its major policies on science. It’s time for the public consultation, far from the greasy paws of lobbyists, and with the best minds that can be brought to the table.

This is a letter to take to heart.

Canadian government in the grip of the nuclear lobby’s NICE dishonest spin about small nuclear reactors.

”…………….To date, not a single SMR has been built in Canada, but no matter, the technology is the current darling of nuclear power circles, and not just at home, either; other countries, from China to the United States, are pursuing the development of SMRs. Currently, 12 proposals for SMR development are winding their way through the Canadian Nuclear Safety Commission’s (CNSC) pre-licensing vendor review process, which enables CNSC staff to provide feedback on proposed designs at a company’s request. But not a single project has yet been approved.

For the time being, any vision of SMRs is largely aspirational. A Conference Board of Canada report in March on SMRs outlined that from concept to commercialization, the technology will require about a billion dollars of development expenditure. The same report noted that as an emerging technology, costs are still uncertain, and the “risky pre-commercial phase needs capital investment, but governments will be reluctant without major private capital commitment.”

It’s early days for financing the technology. For instance, one infusion of federal funds, the $50 million granted to New Brunswick’s Moltex Energy in mid-April, only supports research and development, employee recruitment and the expansion of academic, research and supply chain partnerships, not the physical construction of that firm’s SMR.

Beyond financial considerations, the Liberal government will have a tough time convincing environmentalists to embrace the merits of SMRs, or any nuclear power, as a clean energy source. More than 100 groups have signed a letter issued by the Canadian Environmental Law Association condemning the government’s push to pursue nuclear power and SMRs. Among their concerns are that SMRs are more expensive to develop than renewable energy and that the reactors are “dirty and dangerous,” creating new forms of radioactive waste that are especially dangerous to manage.

For now, however, nothing is slowing the momentum. In mid-April, the Canadian Nuclear Association triumphantly announced Alberta was joining Ontario, New Brunswick and Saskatchewan in the development of SMRs.

Those aren’t the only recent developments in the burgeoning SMR industry. Ontario Power Generation is teaming up with SMR developer Ultra Safe Nuclear Corporation to develop a micro modular reactor at Chalk River. Ontario Power Generation is also carrying out engineering and design work on SMRs with GE Hitachi, Terrestrial Energy, and X-energy…….

Europe is now shifting away from nuclear power. In 2019, solar installed capacity exceeded nuclear for the first time in the EU, with 130 gigawatts versus 116 gigawatts, according to the World Nuclear Industry Status annual report, which provides independent assessments of global nuclear developments. And a technical expert group convened in the EU chose not to recommend nuclear energy when asked to advise on screening criteria that would substantially contribute to climate change mitigation or adaptation while “avoiding significant harm” to other environmental objectives.,…..

the federal government has been lobbying hard on behalf of the industry since at least 2019. The Department of Natural Resources, for instance, is a member of the international initiative Nuclear Innovation: Clean Energy Future, or as it’s better known, NICE,  Besides Canada, members include Japan, the United States, and a number of nuclear associations. The goal “is to ensure that nuclear energy receives appropriate representation in high-level discussions about clean energy.”

Freelance researcher Ken Rubin turned up a number of documents using freedom-of-information requests that showed the federal government is collaborating with NICE and others to promote nuclear power and SMRs. The federal government, for example, offered $150,000 for the development of a “Top 20 book of short stories” on “exciting near-term nuclear innovations” designed to showcase nuclear power as an environmental force for good. The book includes stories on the safe storage of nuclear waste as well as on the emerging SMR market.

According to the book, uses for the latter technology include “energy parks” providing heat for industrial processes, steam for heating and electricity for cooling homes, offices and shops, all without emissions. The story breathlessly declares: “This isn’t science fiction.”

No matter how hard the government lobbies the public for a NICE future, though, it’s going to remain a tough sell to Canadian environmentalists. While the environmentalists have nothing specific to fight yet, given that a viable SMR has yet to be built, they’ll be ready when the technology reaches development. Already, a who’s who of groups has signed a letter protesting the next thing in nuclear.

Theresa McClenaghan, CELA’s executive director and counsel, told Canada’s National Observer: “It’s not a climate answer for many reasons, including the fact it’s not realistic and it’s way too far down the road for us to meet any serious climate targets. We’ve characterized it as a dirty, dangerous distraction.”

Susan O’Donnell, a researcher and adjunct professor in the Department of Sociology at the University of New Brunswick and a nuclear activist, says SMRs are too slow and costly as a climate crisis solution. “It’s important to remember that these technologies basically don’t exist yet,” she said. “They’re at a very early stage in development. They are speculative technologies. It will take at least a decade to get them off the drawing board and then it will take much longer than that to find out if they work.” – from the Bulletin of the Atomic Scientists , 20 May 21
