Small nuclear reactors are unproven and years away from being in use. But the Alberta government is presenting them as a way to keep fossil fuels flowing.
The untested technology is more about greenwashing than about cutting emissions.
Alberta's government is really excited about nuclear power.
More specifically, about novel and unproven small modular nuclear reactors. It hopes to use these to help lower the province's carbon emissions while letting the energy industry continue operating as usual — an enticing prospect to the government given its intention to increase oil and gas production, while still having the energy sector get to net zero by 2050.
Small modular nuclear reactors produce less than one-third of the electricity of a traditional reactor.
The premise is that small reactors are easier to place and build, and cheaper.
Alberta hitched its horse to this wagon with Ontario, New Brunswick and Saskatchewan in 2022, taking part in a strategic plan for small modular reactor development and deployment. Alberta Innovates, the province's research body, had a feasibility study conducted for it by Pacific Northwest National Laboratory. The study focused on using the reactors for greenhouse-gas-free steam emissions for oilsands projects, electricity generation in our deregulated market and providing an alternative to diesel when supplying power to remote communities.
More recently, Ontario Power Generation and Capital Power out of Edmonton entered into an agreement to assess SMRs for providing nuclear energy to Alberta's grid. Nathan Neudorf, Alberta's minister of affordability and utilities, was gleeful. "This partnership represents an exciting and important step forward in our efforts to decarbonize the grid while maintaining on-demand baseload power," he said of the announcement.
All of this buzz makes it seem like SMRs are just over the horizon, an inevitability that will allow the province to evolve to have a cleaner, modern energy landscape.
But small modular reactors are nowhere near ready for deployment, and won't be in Alberta for about a decade. That means for 10 years, they'll provide no GHG-free steam to mitigate emissions.
"It's still in the design phase," Kennedy Halvorson said, speaking about the reactors. Halvorson is a conservation specialist with the Alberta Wilderness Association. The reactors are "so far off from being able to be used for us," Halvorson added. "The earliest projections would be 2030. And we need to be reducing our emissions before 2030. So, we need to have solutions now, basically."
With SMRs unable to stem the emissions tide for years, it's confusing as to how they could make enough of a difference to get Alberta to net zero by 2050 (in line with United Nations emissions reduction targets to keep global warming to no more than 1.5 degrees).
Capital Power made similar projections...................................................................................
Construction itself is only one piece. Adding to that is the need to build a regulatory framework, which Alberta doesn't have for nuclear.............................................................
Ontario's nuclear troubles
Listening to these public voices is prudent. We can look east to see what happens when the government and power utilities sidestep the process of getting explicit consent from communities that stand to be affected.
With its status as the nuclear activity hub in Canada, we can use Ontario as a litmus test of sorts and gauge Canada's track record of care with nuclear. The report card isn't great. There have been multiple cases of improper consultation with Indigenous Peoples on whose lands the waste, production or extraction sites are placed...................................................................................
Small reactors face a critical economic challenge
Adding to the timeline troubles are questions as to whether small reactors truly offer that much of an economic advantage, if any, compared with their larger counterparts.
In a previous article Ramana wrote, he pointed to the first reactors as an indication of the answer.
The first reactors started off small. Their size, though, coupled with the exorbitant price tag of nuclear development, meant they couldn't compete with fossil fuels.
The only thing they could do to reduce the disadvantage was to build larger and larger reactors, Ramana said.
A large reactor that could produce five times as much electricity didn't cost five times as much to build, he said, improving the return from the investment.
Economically the SMR can't seem to compete with its larger sibling. Adding this to the delays abundant with nuclear, controversies around construction and communities, and the misalignment of timelines for meeting climate commitments, we need to ask why we're seeing such a fervent enthusiasm for small modular reactors.
Greenwashing by any other name
The answer is likely a simple one: The Alberta government wants to keep the taps on. Their friends in the energy industry do too. Like carbon capture and sequestration before it, SMRs are the next way to stave off pesky talk of divestment and transition......................................................................
Deflecting and delaying isn't the only greenwashing happening either, Halvorson argued. She noted there's a special kind of tactic that comes with nuclear and other "clean" technology, where only carbon dioxide and greenhouse gas offsets are counted.
"When we reduce it all to just how much CO2 something emits, we're not getting the full picture of environmental impacts," Halvorson said. She pointed to water use in nuclear as an example.
"Most nuclear technologies require a massive input of water to work. And as we know, right now we're in a drought in Alberta. Our water resources are so precious. We already have industries that are using way too much water as is, in a way that's not allowing our environments and ecosystems to replenish their reserves, like their water resources," she said.
