The Strategic Push for Small Modular Reactors
In a bold move that could reshape how tech giants power their operations, Amazon has doubled down on its commitment to nuclear energy through a strategic partnership with X-Energy. The collaboration aims to deploy up to 960 megawatts of small modular reactor (SMR) capacity in Washington State, representing one of the most significant corporate investments in next-generation nuclear technology. This initiative comes as cloud providers face increasing pressure to find reliable, carbon-free power sources for their energy-intensive data centers.

Amazon’s $500 million investment in X-Energy signals a fundamental shift in how major technology companies approach their energy infrastructure. Rather than relying solely on traditional power grids or renewable sources with intermittency issues, Amazon is betting that SMR technology can provide the baseload power needed to support its growing cloud computing operations while meeting sustainability targets.
Technical Specifications and Deployment Timeline
The planned Cascade Nuclear Energy Center near Richland, Washington will feature X-Energy’s Xe-100 reactors, each capable of generating 80 megawatts of power. The deployment will occur in three phases, with each phase adding 320 megawatts of generation capacity. To put this scale in perspective, the total output would be sufficient to power multiple massive data centers simultaneously, given that xAI’s Colossus supercomputer with 200,000 GPUs consumes approximately 300 megawatts at full utilization.
However, the ambitious project faces a lengthy timeline, with construction not expected to begin until the late 2020s and operations commencing in the 2030s. This extended schedule reflects both the regulatory hurdles and technical challenges inherent in deploying first-of-a-kind nuclear technology. The extended timeline for these nuclear power initiatives highlights the complex planning required for such massive energy projects.
Regulatory and Economic Challenges
X-Energy’s path to deployment is far from guaranteed. The company’s SMR technology has yet to receive crucial approval from the Nuclear Regulatory Commission, a process that typically takes several years and requires extensive safety documentation. This regulatory landscape presents significant uncertainty, particularly as digital governance frameworks continue to evolve alongside emerging technologies.
Economically, the SMR proposition remains unproven at commercial scale. Previous SMR projects have encountered higher-than-expected operating costs that undermined their viability. The industry is watching closely to see if X-Energy can deliver on promises of smaller footprints, faster deployment, and lower operating costs compared to conventional pressurized water reactors.
Broader Industry Context and Competition
Amazon is not alone in pursuing nuclear solutions for its power needs. The industry is witnessing multiple parallel developments:
- Oracle plans to deploy at least three SMRs to power gigawatt-scale operations
- Google-backed Kairos Power aims to build a 50MW molten salt reactor in Tennessee
- Microsoft is financing the restart of Pennsylvania’s Three Mile Island Unit-1 reactor
This surge in corporate nuclear interest coincides with significant private investment in fusion energy and other advanced nuclear technologies, creating a diverse ecosystem of next-generation power solutions.
Alternative Approaches and Backup Strategies
While betting heavily on SMRs, Amazon is simultaneously pursuing more immediate nuclear solutions. The company’s $650 million acquisition of Cumulus Data’s atomic data centers in Pennsylvania provides access to 2.5 gigawatts of existing nuclear capacity, with potential to scale to 960 megawatts under the agreement. This dual-track approach demonstrates Amazon’s pragmatic recognition that SMRs represent a long-term solution requiring complementary near-term strategies.
The broader energy infrastructure supporting these initiatives requires careful consideration of grid modernization efforts to ensure reliable power delivery to data centers and other critical facilities.
Security Implications and Future Outlook
As digital infrastructure becomes increasingly dependent on specialized power sources, security considerations take on heightened importance. The intersection of nuclear facilities and data centers creates unique vulnerabilities that must be addressed through robust cybersecurity measures. Recent advancements in cybersecurity threats highlight the importance of securing both digital and physical infrastructure.
Looking forward, Amazon’s partnership with South Korea’s Doosan Enerbility and Korea Hydro and Nuclear Power suggests a global approach to SMR deployment. This international collaboration could accelerate technology transfer and deployment expertise, potentially benefiting multiple related innovations in the nuclear energy sector.
Despite the challenges, Amazon’s commitment to deploying 5 gigawatts of X-Energy SMRs by 2039 represents a watershed moment for corporate energy strategy. The success or failure of this initiative will likely influence how other technology companies approach their own power needs and sustainability commitments in the coming decades.
