The NEA SMR Dashboard provides a comprehensive assessment of the progress made by SMR designers and companies worldwide. Looking beyond technical feasibility, the NEA SMR Dashboard defines new criteria for assessing real progress in six additional dimensions of readiness: licensing, siting, financing, supply chain, engagement, and fuel. The compilation of the NEA SMR Dashboard reveals substantial progress towards SMR deployment and commercialisation in NEA and non-NEA member countries, with much of this progress taking place during the past two years.
The first two volumes of the first edition track the progress of 42 SMRs around the world. Volume I of the NEA SMR Dashboard was launched during the US Nuclear Regulatory Agency’s (NRC) Regulatory Information Conference on 13 March 2023. Volume II of The NEA SMR Dashboard was published in July 2023 during the 14th Clean Energy Ministerial in Goa, India on 19 July 2023. The NEA SMR Dashboard: Edition II, published in 2024, provides the assessment of 56 SMRs around the world. In July 2025, the NEA SMR Dashboard: Edition III was published, providing the most comprehensive global review to date, identifying 127 SMR technologies, of which 74 are featured in the current edition. The NEA also launched the NEA SMR Digital Dashboard as an interactive platform, providing users with regularly updated data and visualizations on the global development of small modular reactors.
To ensure the NEA SMR Dashboard remains current and reflective of ongoing developments, the NEA employs two complementary update strategies:
The NEA has developed a Microsoft form and accompanying guidelines to facilitate updates to SMR design assessments in the NEA SMR Dashboard. To collect these updates, the NEA will issue several reminders each year on its website and social media platforms.

In 2018, the Intergovernmental Panel on Climate Change (IPCC) considered 90 pathways for emission reductions sufficient to limit average global warming to less than 1.5°C (IPCC, 2018). The IPCC found that, on average, these pathways require nuclear energy capacity to increase to 1 160 gigawatts by 2050, from 394 gigawatts in 2020 (IPCC, 2018).
The role of nuclear energy in achieving net zero was recognised at COP28 when over 20 countries committed to tripling nuclear energy capacity by 2050.
The commitment to triple global installed nuclear capacity by 2050 aligns with NEA’s analysis, which concludes that to meet climate goals consistent with a 1.5°C scenario, global nuclear capacity needs to reach 1 160 gigawatts by 2050.
As a class of reactors, SMRs are defined by their smaller size, but there is considerable variety within this class of reactors; they vary by power output, temperature output, technology and fuel cycle. A number of SMRs are based on existing commercially deployed light water technologies, while others are based on advanced design concepts, offering a range of sizes – from 1 MWe to over 300 MWe – and a range of temperatures – from 285°C to more than 850°C, to meet the specific energy needs of hard-to-abate industrial sectors.
