The NWMO completes borehole drilling program in two potential siting areas to ensure safety in deep geological repository
TORONTO, April 7, 2022 – After more than 10 years studying the geology in two potential siting areas, the Nuclear Waste Management Organization (NWMO) has completed a deep borehole drilling program that marks a key milestone in site investigations to confirm a safe location for a deep geological repository to safely contain and isolate Canada’s used nuclear fuel. Some of Canada’s top geoscientists are leading the studies, in which approximately eight kilometres of core samples were pulled from the bedrock at two Ontario sites under consideration for the project – one in the Wabigoon-Ignace area and the other in the Saugeen Ojibway Nation (SON)-South Bruce area.
Nuclear energy has powered Canadian communities for decades, and the planned repository is part of Canada’s plan to safely manage the resulting used nuclear fuel over the long term. The project will be one of the largest environmental infrastructure projects in Canadian history.
“Deep geological repositories are internationally recognized as the safest way to manage used nuclear fuel over the very long term,” says Lise Morton, Vice-President of Site Selection at the NWMO. “Completion of this drilling program is a significant step forward in our geoscience work. In addition to informing the safety case for the project, the resulting data will also provide important insights to the communities that are considering hosting the project in their area.”
Canada’s plan calls for centralized containment and isolation of Canada’s used nuclear fuel in suitable rock formation in an area with informed and willing hosts. The community-driven siting process launched in 2010, and by 2012, 22 communities had expressed interest in learning about the project and exploring their potential to host it. The NWMO is on track to finalize site selection in 2023.
The completion of the last borehole at the potential site in the SON-South Bruce area follows on work in the Wabigoon-Ignace area, which wrapped up in November 2021 after five years of intensive field study that started in 2017. Borehole drilling and testing up to 1,000 metres below the surface is part of the NWMO’s broader site investigation work to ensure the site will meet stringent regulatory requirements. Safety and security underpin the NWMO’s work, guided by a responsibility to protect people and the environment.
Canada’s plan for used nuclear fuel, known as Adaptive Phased Management, emerged through extensive dialogue with Canadians and Indigenous peoples from coast to coast to coast, and aligns with the values and priorities they identified as important. The site selection process was designed to ensure the location chosen will be safe and secure, and we will only proceed with the support of informed and willing hosts. It reflects the ideas, experience and best advice of a broad cross-section of Canadians and Indigenous peoples who shared their thoughts on what an open, transparent, fair and inclusive process for making this decision would include.
About the NWMO
The Nuclear Waste Management Organization (NWMO) is a not-for-profit organization tasked with the safe, long-term management of Canada’s used nuclear fuel inside a deep geological repository, in a manner that protects people and the environment for generations to come.
Founded in 2002, the NWMO has been guided for 20 years by a dedicated team of world-class scientists, engineers and Indigenous Knowledge Keepers that are developing innovative and collaborative solutions for nuclear waste management. Canada’s plan will only proceed in an area with informed and willing hosts, where the municipality, First Nation and Métis communities, and others in the area are working together to implement it. The NWMO plans to select a site in 2023, and two areas remain in our site selection process: the Wabigoon-Ignace area in northwestern Ontario and the Saugeen Ojibway Nation-South Bruce area in southern Ontario.
“We need to be sure that used nuclear fuel can be safely contained in the rock to ensure water, people and the environment are safe,” said Sarah Hirschorn, Director of Geoscience at the NWMO. “This work will support greater understanding of geological characterization so that local communities are informed as they consider what will be one of the largest environmental infrastructure programs in Canadian history.”
Local South Bruce
“As part of the site selection process, we are collaborating with the community to build an understanding of what a state-of-the-art deep geological repository could look like here in South Bruce,” said Tareq Al-Zabet, Site Director for South Bruce at the NWMO. “Safety, water protection and environmental stewardship are paramount to decision-making. The important work our geoscience team is doing on site is critical to confirm the suitability of Canada’s deep geological repository here in South Bruce – we look forward to our next stage of site selection.”
“The borehole drilling studies are a key source of data we will analyze to be sure that used nuclear fuel can be contained and isolated in the rock, ensuring water, people and the environment are safe,” said Bill Gascon, Site Director for Ignace at the NWMO. “We are committed to working with communities, including municipal, First Nation and Métis communities, and others in the area. We will only site this project in an area with informed and willing hosts.”
