2024 Nuclear SMR Innovators: Industry Leaders and Progress

In this summary, we spotlight the 2024 Nuclear SMR Innovators, as identified in Reuters Events’ comprehensive report

In the realm of nuclear energy, the year 2023 was a period of both challenges and opportunities. Particularly, for the market of advanced nuclear and small modular reactor (SMR) technologies there has been a dynamic shift. Notably, despite facing setbacks such as canceled orders and rescinded awards, these technologies have remained integral in the global effort to combat climate change. Consequently, their role in providing low-carbon energy sources has gained increasing recognition and importance. In this article, we will highlight 50 companies that have made significant strides in the advanced nuclear and SMR sector in 2023 and are poised to shape the industry in 2024 and beyond. 

Please note that this list is not exhaustive, and the inclusion or exclusion of a company does not reflect its standing in the industry. The companies listed below are not ranked in any order, and their position in this report does not indicate their importance within the nuclear value chain. 

Leading Utilities Among 2024 Nuclear SMR Innovators


Firstly, Nuclearelectrica, a Romanian utility, is set to become the first to deploy a NuScale SMR after a previous deal fell through. The company plans to install a NuScale VOYGR unit at its Doicești thermal power plant site.

2024 Nuclear SMR Innovators: Key Financers and Banks

Bank of America 

In the financial sector, Bank of America’s Research Investment Committee issued a report in May 2023, forecasting a 20 to 40% upside on uranium and nuclear power. The bank’s analysts expressed bullishness on the industry, countering the challenging outlook for SMRs. 


In contrast, Citigroup Global Markets joined UBS Securities in advising special purpose acquisition company (SPAC) Ares Acquisition Corporation on its $1.8 billion merger with X-energy and provided financial advice for Oklo’s $850 million equity SPAC deal with AltC Acquisition Corp. 

International Bank for Nuclear Infrastructure 

Significantly, the International Bank for Nuclear Infrastructure is positioning itself as a key financier for SMRs by signing up nuclear markets like Canada, France, and the U.S. to act as a multilateral lending organization. 

Other Players to Watch: 

The Finance Ministry of Estonia for progressing with SMR site identification. 

Gugenheim Securities for providing financial advice on Oklo’s SPAC transaction. 

Jiude Capital for seed funding of Singaporean SMR hopeful Heatnuc.
