Summary of THE GROWTH & FUTURE OF SMALL MODULAR REACTORS

Core Content

Small Modular Reactors (SMRs) are emerging as a promising solution to address the growing energy gap and support global net zero goals. As traditional fossil fuel-based power generation is phased out, SMRs offer a way to provide reliable, low-carbon baseload power. This report explores the opportunities and challenges of deploying SMRs at scale, focusing on technology, cost, supply chain, investment, regulation, and market development.

Main Viewpoints

• Nuclear Power's Role in Net Zero: Nuclear energy is expected to play a central role in providing continuous baseload power. By 2023, the global nuclear capacity was 371.5 GW(e), with over 30 countries considering new nuclear programs.
• SMR Potential: SMRs are smaller, faster to deploy, and potentially cheaper than large nuclear power plants (LNPPs). Their modular design allows for mass production and standardization, which can reduce costs and deployment times.
• Challenges in Deployment: Despite their potential, SMRs have not yet seen successful deployment in Western countries. Barriers include high upfront costs, regulatory hurdles, and the need for a mature supply chain and investor confidence.
• FOAK Deployments as Critical Milestones: First-of-a-kind (FOAK) deployments are essential to proving the feasibility of SMR designs, reducing future costs, and building trust among stakeholders. These projects serve as testbeds for innovation, supply chain development, and regulatory alignment.
• Technology Diversity: SMR designs vary significantly, with some based on Gen III/III+ reactors (adaptations of existing large nuclear technologies) and others on Gen IV designs (innovative and experimental technologies). Both types are progressing toward commercialization, though Gen IV reactors are less mature and face more regulatory and technical challenges.

Key Information

1. Technology Landscape

• Gen III/III+ Reactors: These designs are based on light water reactors (PWRs and BWRs) and leverage existing technologies. Examples include:

  • ACP100 (China): First land-based SMR, with construction ongoing in Hainan.
  • BWRX-300 (GE Hitachi): Targeted for deployment in Canada by late 2029.
  • AP300 (Westinghouse): Based on AP1000 technology, expected to be submitted for design certification by 2027.
  • CAREM (Argentina): A PWR design, with construction suspended due to funding issues.
  • Rolls-Royce SMR: Designed for baseload electricity, with regulatory approval in the UK and potential deployment in Czechia.

• Gen IV Reactors: These are experimental and innovative designs using alternative coolants and fuels. Examples include:

  • TerraPower (Natrium Project): Sodium-cooled fast reactor with energy storage, expected to complete its draft EIS by 2025.
  • Kairos Power (KP-FHR): Fluoride salt-cooled reactor using TRISO fuel, with a demonstration reactor under construction.
  • Xe-100 (X-energy): HTGR design, expected to reach commercial deployment by 2039.
  • LFR-AS-200 (Newcleo): Lead-cooled fast reactor using MOX fuel, aiming for a 30 MWe prototype by the early 2030s.

2. Cost Competitiveness

• LCOE Targets: SMRs must achieve a competitive levelized cost of energy (LCOE) to be viable in the market. This involves aligning with current energy prices and ensuring cost efficiency relative to other generation methods.
• Market Dynamics: Baseload consumers are willing to pay a premium for continuous power, and SMRs can compete by setting LCOE targets between intermittent and baseload sources.
• FOAK as a Learning Tool: FOAK projects are critical for reducing future costs through standardization and scaling. Lessons from adjacent industries (wind, shipbuilding, aerospace) suggest that cost reductions and efficiency gains are possible through experience and innovation.

3. Supply Chain Maturity

• Ecosystem Approach: SMR deployment requires a mature and industrialized supply chain. This involves collaboration between public and private sectors, including equipment manufacturers, construction firms, and regulators.
• Reduced Supply Chain Complexity: The decline in large nuclear projects has reduced the supply chain for nuclear components, making it essential to scale and industrialize SMR production to ensure cost efficiency and timely deployment.

4. Investment Risk & Government Support

• Long Timelines: SMR projects require long lead times, making it difficult to attract and retain investor interest. Government support is crucial for de-risking investments and ensuring long-term funding.
• Public-Private Collaboration: Governments can provide regulatory clarity, financial incentives, and infrastructure support to make SMRs more attractive to investors and utilities.

5. Regulatory Harmonization

• Need for Adaptation: Current nuclear regulations are tailored for large reactors, which can delay SMR projects. Harmonizing regulations across jurisdictions is necessary to accelerate deployment and enable global scaling.
• FOAK as a Catalyst: A successful FOAK deployment in a Western country will provide a regulatory model and increase confidence among utilities and investors.

6. Market Development

• Utility and Consumer Roles: Utilities need to act as intelligent owners to drive SMR adoption, while consumers must commit to baseload power requirements to ensure market viability.
• Early Involvement: Early engagement from both consumers and utilities is essential to meet demand thresholds and support the development of SMR projects.

Conclusion

SMRs represent a significant opportunity to provide reliable, low-carbon energy in the transition to net zero. However, their success depends on overcoming key challenges related to technology maturity, cost competitiveness, supply chain development, investment risk, and regulatory alignment. With the right strategies and collaboration, SMRs can become a cornerstone of the global energy transition, offering scalable, sustainable, and economically viable solutions.
