In partnership with interested provinces, territories and power utilities, Natural Resources Canada has convened a roadmap to engage stakeholders on the future of small modular reactors in Canada. Through a series of expert working groups, and workshops held across Canada, the roadmap has gathered feedback on the direction for the possible development and deployment of SMRs in Canada.

what is a small
modular reactor?

...........................

Small Modular Reactors (SMRs) are nuclear fission reactors that are being designed to be built at a smaller size but in larger numbers than most of the world’s current nuclear fleet. Some small nuclear reactors have existed since the beginning of reactor technology fifty years ago. Examples include research reactors at universities (of which there are several in Canada), demonstration reactors (built prior to scaling up
a design for commercial electricity supply), and marine propulsion reactors (used in vessels of several navies for decades). SMRs are being designed to be:

  • Small – in both power output and physical size;
  • Modular – meaning they are factory constructed, portable and scalable;
  • Reactors – using nuclear fission to produce energy: energy for electricity, hybrid energy systems, district heating, water desalination, and high quality steam for heavy industry applications.

economic competitiveness

...........................

Canada has one of the world’s most promising domestic markets for SMRs. Conservative estimates place the potential value for SMRs in Canada at $5.3B between 2025 and 2040. Globally, the SMR market is much bigger, with a conservative estimated value of $150B between 2025 and 2040. This represents a large potential export market for Canada, which has already exported nuclear reactor technology to six other countries.

Canada has a window of opportunity to lead as it has all the necessary elements – a strong international brand, flexible and performance based regulator, world class nuclear laboratories and demonstration sites, a mature supply chain and domestic uranium mining industry, extensive nuclear operating experience, and strong science and technology in related areas (materials science, medicine, irradiation/sterilization, food safety).

IN CANADA, SMRs HAVE THREE MAJOR AREAS OF APPLICATION:

  • On-grid power generation, especially in provinces phasing out coal in the near future. Utilities want to replace end-of-life coal plants with non-emitting base-load plants of similar size. Larger SMRs are likely to align to this application.
  • On- and off-grid combined heat and power for heavy industry. Oilsands producers and remote mines would benefit from medium-term options for bulk heat and power that would be more reliable and cleaner than their current energy sources. Small or medium SMRs are likely to fit this need.
  • Off-grid power, district heating, and desalination in remote communities. These currently rely almost exclusively on diesel fuel, which has various limitations (e.g. cost, emissions). Renewables and batteries can mitigate these limitations to some extent for residential power, but may not supply building heat, nor are they likely to offer reliable bulk energy to open up economic development. Very small SMRs may address these needs.

innovation

...........................

SMRs are a re-scaling and repurposing of nuclear technology for wider markets. They represent a paradigm shift for nuclear reactor technology – analogous to the shift of steam engines from mineshafts into ships and vehicles, or the movement of computers from mainframe to desktop and then to laptop.

Traditionally, nuclear energy has primarily been used to provide baseload power to large power grids, such as Ontario’s, where nuclear provides over 60% of the province’s electric power with very low emissions. SMR designs should be able to take nuclear to smaller power grids (Saskatchewan), off-grid (remote mines and northern communities), allow for greater load following (to replace fossil fuels) and support the integration of more intermittent renewables in the grid within hybrid systems. SMRs could also potentially lead to greater greenhouse gas reductions through the decarbonisation of the transportation industry, which could also be an enabler for improved infrastructure (such as high speed electric rail services). All of these capabilities could make a dramatic difference in Canada’s ability to meet its Paris Accord commitments to reduce greenhouse gas (GHG) emissions.

There are over 150 proposed designs for SMRs worldwide. This number reflects both the excitement around their potential, and also the wide spectrum of possible nuclear reactor technologies. Some of these are in current commercial use, some have been physically demonstrated in the past, some are being prototyped now, and some are still conceptual. Most of these designs incorporate innovative features, including passive safety (if the system is not actively managed, it shuts itself down safely), inherent safety (making harmful emissions physically impossible), design for easy manufacture, and many years of operation on a single load of fuel. Some designs even have the potential to reduce the amounts of radioactive waste from existing reactors by closing the fuel cycle, where spent fuel is processed and partly reused.

Some SMR designs could be deployed in the near term with most available within the next 7 to 15 years. For some of the more tested technologies, the timeline challenges are not so much with the reactor design as with economic, social, regulatory and waste management issues that need to be clarified, including: who owns and operates the reactor, how is it licensed, how are risks shared, who owns the waste and how is it managed, and community engagement.

On the other hand, for some of the more innovative reactor technologies, many technical questions remain to be resolved, which may require additional years of investment in computer modelling, prototype or demonstration reactors, and operating experience.

pan-Canadian approach

...........................

Through the six-month Generation Energy dialogue in 2017, Natural Resources Canada (NRCan) heard that Canadian partners would need to work together to realize the potential for SMRs. In response, NRCan convened the SMR Roadmap Project with interested provinces, territories and power utilities. The Project is a ten-month program of engagement with the nuclear industry, as well as potential end-users such as Northern and Indigenous communities and heavy industry stakeholders, to explore the potential scope for a national path forward for SMRs.

key findings from the roadmap

...........................

KEY FINDINGS FROM THE ROADMAP

FINDING 1

Successful SMR deployment will likely require a ‘fleet’ based approach to operations in order to benefit from standardization and economies of series (i.e. capital costs decrease as more units are produced).

FINDING 2

Demonstrating SMR technology in Canada is key to capturing first mover advantage. Canada’s three applications will likely have different demonstration ‘tracks’.

FINDING 3

Appropriate risk sharing among governments, power utilities and industry will be necessary for SMR demonstration and deployment in Canada.

FINDING 4

Public and Indigenous groups, as well as other potential end-users, have concerns about safety, waste management, and overall cost of SMRs. Ongoing engagement and knowledge-sharing will be important as more information on SMRs becomes available.

FINDING 5

Canada’s regulatory framework and waste management regime are well-positioned to respond to the SMR paradigm shift, but some modernization will be necessary to reflect the reality of the smaller size of an SMR.

frequently asked questions

...........................

What are the goals of the Roadmap?

The Roadmap aimed to foster innovation and establish a long-term vision for the nuclear industry, as well to assess the characteristics of different SMR technologies and their alignment with Canadians’ requirements and priorities.

The goal of the Roadmap was to hold a national conversation about the needs and priorities of Canadians that will lead to understanding the value of SMRs, identify some key issues around their use, their potential risks and challenges, and identify some policies that could influence the feasibility of SMRs in Canada – and then to chart a path forward.

What is the process and timeline for the Roadmap?

The Roadmap was built with a collaborative, national approach, both with respect to its leadership and engagement – all interested provinces, territories, and power utilities from across Canada were invited to join the Steering Committee.

The Roadmap began with a Visioning Workshop in March 2018, followed by three application specific (e.g., On-grid, Remote and Heavy Industrial) workshops between April and June 2018. Concurrently five expert working groups analyzed key areas: Technology, Economics and Finance, Public and Indigenous Engagement, Waste Management, and Regulatory Readiness.

The report A Call to Action – A Canadian Roadmap for Small Modular Reactors will be launched at Canada’s 1st International Conference on Generation IV and Small Reactors on November 7, 2018, in Ottawa, Ontario.

The Roadmap is an ongoing project with many recommendations to key enablers.

Why weren’t all of the provinces and territories included in the Pan-Canadian SMR Roadmap?

Natural Resources Canada invited all Canadian provinces and territories to join the Steering Committee. Only Alberta, Saskatchewan, Ontario, New Brunswick, Nunavut and the Northwest Territories responded, and they are on the SMR Roadmap Steering Committee.

How much did the Roadmap cost the Government of Canada?

The Government of Canada, through Natural Resources Canada’s Energy Innovation Program, contributed approximately $200,000.00 to the Roadmap initiative.

The SMR Roadmap Steering Committee members shared the remainder of the cost of the project.

Were Indigenous groups engaged during the Pan-Canadian SMR Roadmap?

At the outset of the SMR Roadmap process, the Steering Committee identified engagement with Indigenous groups in Canada as an important component of the process and committed to beginning a constructive and respectful conversation with Indigenous groups and communities.

Indigenous engagement sessions took place in New Brunswick, Alberta and Nunavut, and focused on regional and sub-regional organizations.

Indigenous engagement that began under the SMR Roadmap was the beginning of a dialogue with Indigenous groups and communities.  Members of the SMR Roadmap Steering Committee will build on this initial engagement to meet with interested groups and communities, including First Nations and Metis groups in Ontario, to encourage a meaningful, two-way dialogue on the potential for SMRs in Canada’s clean energy mix.

What are the next steps?

The Pan-Canadian SMR Roadmap is a call to action with recommendations across four pillars:

Demonstration and deployment – Governments should provide funding to cost-share demonstration projects with industry.  Federal and provincial governments should implement measures to share risk with private investors to incentivize first-commercial deployment of SMRs in Canada, with the potential of exporting SMR technologies and related innovations developed in Canada to international markets.

Indigenous engagement – Building on the constructive dialogues that were launched under the Roadmap, it is recommended that enablers continue with meaningful, two-way engagement with Indigenous peoples and communities on the subject of SMRs, well in advance of specific project proposals.

Legislation, regulation, and policy – The Roadmap includes various recommendations on federal impact assessment, nuclear liability, regulatory efficiency and waste management.

International partnerships and markets – The federal government, with support from industry, laboratories, and academia, should continue strong and effective international engagement on SMRs, in particular to influence the development of international enabling frameworks.
