Global Gathering to Discuss the Future of Small Modular Reactors
The International Atomic Energy Agency (IAEA) is hosting a groundbreaking conference on Small Modular Reactors (SMRs) from October 21 to 25 at its headquarters in Vienna. This event, which is expected to draw more than 1,000 participants from almost 100 different countries, is happening at a pivotal moment for global energy policy. As nations worldwide increasingly recognize the role of nuclear power in achieving net-zero emissions by 2050, the conference aims to explore the strategic importance of SMRs in this global energy transformation.
Understanding Small Modular Reactors
SMRs are a new frontier in nuclear technology. Unlike traditional nuclear reactors, these compact units are designed to generate up to 300 megawatts of electricity (MW(e)), making them particularly suitable for remote areas or regions with smaller electricity grids. Their modular design allows for factory assembly of components, which are then transported to their deployment sites. This process can significantly reduce construction time compared to traditional nuclear plants.
As energy demands grow and the call for decarbonization becomes urgent, SMRs present a versatile solution. They are increasingly seen as a viable option for industries with high energy needs, such as data centers, and for various non-electric applications. The IAEA anticipates a substantial expansion of nuclear power by the mid-century, with SMRs playing a key role in the future energy mix.
Future Projections and the Role of SMRs
According to the IAEA’s latest projections, nuclear electrical generating capacity is expected to more than double by 2050. A significant portion of this growth—around 25%—is projected to come from SMRs. IAEA Director General Rafael Mariano Grossi emphasizes the importance of timely development and deployment of SMRs to meet the low-carbon energy needs of countries and industries. He stressed the necessity of international cooperation and collaboration to ensure these technologies are safe, secure, and efficiently deployed.
Key Topics and Discussions at the Conference
The conference will feature a variety of panel discussions and poster sessions focusing on four main topics:
1. **SMR Design, Technology, and the Fuel Cycle**: Exploring the latest advancements in SMR technology and their fuel management strategies.
2. **Legislative and Regulatory Frameworks**: Discussing the policies and regulations necessary to support SMR deployment.
3. **Safety, Security, and Safeguards**: Ensuring that SMRs adhere to the highest safety and security standards.
4. **Facilitating SMR Deployment**: Identifying strategies to promote the widespread adoption of SMRs.
Aline des Cloizeaux, Director of the IAEA’s Division of Nuclear Power, notes that there are currently around 70 active SMR designs at various stages of development worldwide. The conference aims to bring together stakeholders from around the globe to discuss the latest developments and strategies for advancing SMR deployment.
Supporting Harmonization and Standardization
In tandem with the conference, the Nuclear Harmonization and Standardization Initiative (NHSI) will hold a plenary meeting. Launched in 2022, NHSI aims to streamline the deployment of SMRs and other advanced reactors by harmonizing regulatory approaches and standardizing industrial practices. The initiative operates on two tracks: regulatory and industry.
The regulatory track has produced three technical documents that propose cooperative approaches to regulatory reviews, including a multinational pre-licensing joint review process. The industry track has developed working papers on streamlining production processes for long-lead items like pressure vessels and on facilitating serial manufacturing of SMR components for quicker deployments. NHSI members will review the progress of these initiatives and plan future activities during the conference.
Growing Interest in SMRs
The broad participation in the conference underscores the growing global interest in SMRs and their potential applications. Anna Bradford, Director of the IAEA’s Division on Nuclear Installation Safety, reaffirmed the IAEA’s commitment to supporting the deployment of safe and secure advanced nuclear reactors, including SMRs.
Industry and Youth Engagement
The conference will include an ‘Industry Night’ on October 22, co-organized with the World Nuclear Association (WNA). This event will feature global vendors showcasing the latest reactor technologies in four panel sessions. Additionally, a young generation event on October 23, co-organized by the International Youth Nuclear Congress (IYNC) and the IAEA, will facilitate discussions on how SMRs and microreactors can contribute to a sustainable and equitable future.
IAEA Assistance Through the SMR Platform
To support countries in deploying SMRs, the IAEA offers a range of services, including technical assistance, capacity building, and research and development coordination. The IAEA Platform on Small Modular Reactors and their Applications serves as the central hub for these activities, providing coordinated support and expertise across all aspects of SMR development, early deployment, and oversight. This platform fosters cooperation and collaboration among Member States and other stakeholders, ensuring the safe and secure deployment of SMRs worldwide.
The conference on SMRs is a significant step towards a more sustainable energy future, highlighting the role of innovative nuclear technologies in addressing global energy challenges. As the world strives to reduce carbon emissions, the discussions and collaborations that emerge from this event may pave the way for a new era of clean, efficient, and versatile nuclear power.
