“Slowpoke” is a suitable name for Quebec’s only working nuclear reactor.
asserted
Slowpoke → work → reactor
It only produces about 20 kilowatts of thermal energy, or enough to power six or seven toasters.
asserted
It → produce → toasters
But scientists and administrators at Polytechnique Montréal hope the reactor, which turns 50 this year, will help spur a revival of nuclear science research in a province where it’s been slowly fizzling out.
asserted
it → hope → province
Slowpoke, which stands for Safe Low-Power Kritical Experiment, looks nothing like the images most people would associate with a nuclear reactor.
asserted
people → stand → reactor
It’s described as a “sealed-container in-pool type research reactor,” and, as the description suggests, it sits in a deep pool, with no cooling towers.
uncertain
it → describe → towers
A steady mechanical hum fills a small room in Polytechnique where only the top of the opening can be seen, flanked by orange-painted concrete blocks.
asserted
top → fill → blocks
Over the years, it’s been used both for research purposes and to train generations of aspiring scientists, said Nicolas Godbout, the director of engineering physics at Polytechnique Montréal.
asserted
Godbout → use → Montréal
“I think that our biggest legacy is the hundreds of highly qualified personnel that have been formed, the expertise,” he said.
asserted
he → think → personnel
“And we see a real need to redevelop and ensure that this expertise continues.”
asserted
expertise → see → need
Continuing that expertise will take some work, however.
asserted
Continuing → continue → work
Fifty years ago, Canada was “pretty much in a leadership position” in the field of nuclear engineering, Godbout said.
asserted
Godbout → say → engineering

The engineering school was also a big part of that expertise, with personnel supporting operations at the now-decommissioned Gentilly-2 nuclear power facility in Bécancour, Que., and contributing research used to design the country’s Candu reactors.
But today, the generation of researchers who once led the field are “pretty much all retired,” Godbout said.
asserted
Godbout → get → field
Foutse Khomh, vice-president of research and innovation at Polytechnique Montréal, says the school is taking steps to reinvigorate its nuclear studies.
asserted
school → say → studies
The university is receiving a $1-million donation over five years from the engineering company AtkinsRéalis in order to create a new nuclear engineering research chair, and Khomh is hoping more industry players will also contribute.
asserted
players → receive → chair
Even as some sectors of society remain opposed, there is a renewed interest in nuclear energy, driven by growing energy needs and climate targets.
asserted
sectors → remain → needs
That includes in Canada, where Ontario, Saskatchewan, New Brunswick and Alberta signed a plan to develop small reactors in 2022.
asserted
Ontario → include → 2022
Last month, Saskatchewan Premier Scott Moe announced he’s looking at building two large reactors somewhere in the province’s northwest by 2042.
asserted
he → announce → 2042
But Khomh points out that nuclear research has uses in a wide variety of fields, beyond energy.
asserted
research → point → energy
“There are a lot of medical applications,” he said.
asserted
he → be → applications
“You also have applications, for example, in mineral exploration and exploitation and so on.”
asserted
You → have → exploration
Regardless of what energy choices are made, “our role as a university is to make sure that we train the engineers that will be ready to answer the call of the society,” he said, adding that the school hopes to hire five professors in the coming years.
asserted
school → make → years
The experts at Polytechnique say the Slowpoke reactor can play an important role in research and training, despite its age.
asserted
reactor → say → age
The reactor is currently used to provide quality assurance for companies by measuring the elements in different products or materials through a process called neutron activation analysis, reactor manager Darren Hall says.
asserted
Hall → use → process
He explains that samples are placed into the reactor, where they become lightly radioactive.
asserted
they → explain → reactor
They are then removed and placed on a detector.
asserted
They → remove → detector
By looking at the “energy signature” coming from the radiation, researchers can then quantify the different elements in the material, Hall says.
asserted
Hall → look → material
“Kind of like when you’re looking at your cereal box at home and you look at the side ingredients and you see sodium, 10 per cent,” he said.
asserted
he → look → sodium
“We essentially do the same thing.
asserted
We → do → thing
As examples, he said the process can be used to detect materials such as arsenic in recycled plastics, or to measure the presence of critical minerals in a mining sample, he said.
asserted
he → say → sample
It can also be used for medical purposes.
asserted
It → use → purposes
Hall says the low-power reactor is also designed with safety features, including shutting off on its own if it reaches a certain temperature.
asserted
it → say → temperature
While Polytechnique’s reactor is turning 50, Hall says it’s far from the oldest in Canada.
asserted
it → turn → Canada
In comparison, McMaster University’s reactor in Hamilton has been operating since 1959.
asserted
reactor → operate → 1959
“We still have about 25 years left of fuel, so we could operate for the next 25 years,” Hall said.
uncertain
Hall → have → years
