David versus Goliath: the battle of a small indigenous community against a federal radioactive waste dump. 

There are fewer than 500 of them, but they have managed to put a stop to a federal nuclear waste dump project worth several hundred million dollars…

Federal authorities plan to store the remains of the Bécancour nuclear power plant, Gentilly-1, in a dump in Chalk River, on the edge of the drinking water source for millions of Quebecers. 

At a time when the Carney government is promoting nuclear power as one of the ways to make Canada an energy superpower, our investigative team has obtained rare access to this ultra-secure complex, which Ottawa wants to hand over to the Americans. We spoke with citizens and experts who are concerned about the environment and the country’s sovereignty.

There are only 365 Anishinabeg living in the tiny Kebaowek First Nation reserve in Abitibi-Témiscamingue. But through their lawyers, they have succeeded in putting a hold on a multi-million-dollar federal radioactive waste dump project on their traditional territory.

In February, the Federal Court ruled that the Canadian Nuclear Safety Commission had not obtained the free, prior, and informed consent of Indigenous peoples before authorizing the construction of the dump, in violation of the United Nations Declaration on the Rights of Indigenous Peoples.

In March, the court determined that the project endangers several species, including the spotted turtle, a threatened species less than 30 centimeters long that lives for about 50 years and reproduces infrequently, as it does not reach sexual maturity until around 20 years of age.

Federal lawyers have appealed both decisions. If they fail to convince the courts, Canadian Nuclear Laboratories (CNL) and Atomic Energy of Canada Limited (AECL) will have to go back to the drawing board and resume consultations. In the meantime, the project, called the “near-surface waste management facility,” is on hold.

A geotextile membrane to contain radioactivity

It is intended to be a permanent storage and disposal site for up to one million cubic meters of radioactive waste. The waste will be placed on a layer of clay, sand, and geotextile approximately 1.5 meters thick, and covered with another layer of sand, rock, and a membrane.

This is not enough to protect the environment from PCBs, asbestos, heavy metals, and dozens of radioactive elements that CNSC plans to bury there, fears physicist Ginette Charbonneau of the Ralliement contre la pollution radioactive (Coalition Against Radioactive Pollution).

” Radioactive waste cannot be disposed of, it can only be isolated. For that, you need more than a membrane,” she insists.

CNSC assures that this buried waste will have “low-level” contamination and will therefore no longer pose a danger to the environment and health in 500 years, at the end of the containment cells’ useful life.

A pile of waste

But nuclear chemist Kerry Burns has his doubts. Retired from Atomic Energy of Canada since 2010, he was tasked with analyzing waste from the Chalk River laboratories to determine its radioactive content.

He explains that, in the past, CNL buried tons of waste in the sand, which they now plan to exhume and place in their new landfill. However, there are no records indicating the precise level of contamination, he says, describing a gigantic pile of mixed waste.

The project site has too much risk to leave anything to chance, insists the scientist: the landfill will be only one kilometer from the Ottawa River in sandy, porous soil.

“If the contamination escapes from the cells, it will very quickly find its way into the water, and it will be extremely difficult to measure and stop,” he warns.

Like Ms. Chabonneau, Mr. Burns argues that the materials should be isolated in a deep geological repository far from water sources.

This is the method used by one of the American companies chosen to manage CNL, Amentum: it isolates low-level waste in New Mexico in the Waste Isolation Pilot Plant (WIPP), which has isolation chambers 660 meters underground.
