Amazon Funds Unproven Small Modular Reactor Project in Indiana
Amazon commits to purchasing power from future SMRs despite significant regulatory and technological hurdles.
1Amazon's Nuclear Energy Strategy
Amazon is funding the development of a new nuclear facility in Sullivan County, Indiana, to support its growing datacenter infrastructure. The project involves deploying 12 small modular reactors, known as the Xe-100 model, developed by X-energy. This initiative aims to provide nearly 1 gigawatt of power, specifically 960 megawatts of grid-connected electricity.
2Technology and Fuel Specifications
The proposed facility utilizes X-energy’s Xe-100 SMR design, which relies on Tri-Structural ISOtropic fuel pellets. These reactors are cooled by helium gas rather than traditional water-based systems. While Amazon has committed to being the first power purchaser, the company has not disclosed the specific financial amount invested in this nuclear expansion project.
3Uncertain Project Timelines
Completion of the Indiana facility is estimated as early as the mid-2030s, though representatives acknowledge this timeline remains highly speculative. Amazon has declined to provide a concrete schedule, noting that the project is subject to development progress. The site, formerly a coal power plant, currently lacks any operational nuclear infrastructure or regulatory approvals.
4US Nuclear Regulatory Landscape
The US nuclear sector faces significant challenges, as no company has yet built a functional SMR. While Russia and China have operational units, the US has only achieved criticality in an experimental unit. X-energy currently lacks a working reactor, placing this project among many ambitious but unproven next-generation nuclear energy initiatives nationwide.
5NRC Approval Pathways Explained
Developers can pursue standard design approval or site-specific permits from the Nuclear Regulatory Commission. Standard approval allows for universal deployment, yet only Nuscale holds this, having failed to complete any construction. Most current projects, including those by Kairos Power and TerraPower, rely on site-specific permits, which require individual blessing for each unique location.
6X-energy's Current Regulatory Status
X-energy is currently seeking a construction permit for a separate project in Texas intended for a Dow Chemical plant. However, that project involves only four reactors, whereas the Indiana site requires approval for 12 units. Because nuclear permits are site-specific, the Texas progress provides limited regulatory momentum for the larger Indiana facility.
7Amazon's Role as Investor
Amazon explicitly stated it will not participate in the regulatory approval process for the Indiana plant. The company defines its role strictly as an investor and the initial power customer. By providing early capital, Amazon aims to de-risk the technology, helping X-energy scale its operations toward commercial availability in the future.
8Industry Context and Viability
The reliance on immature technology highlights the risks inherent in tech giants driving nuclear energy adoption. With no functional SMRs operating in the US and complex permitting requirements, the Indiana project remains in the speculative phase. Future success depends entirely on overcoming these systemic regulatory hurdles and proving the viability of SMRs.
