Data centers are investing heavily in small modular nuclear reactors (SMRs) to address growing energy demands, reliability, and environmental pressures, but expert analysis points to significant delays, high costs compared to renewables, regulatory challenges, and safety concerns slowing commercial deployment.
This Wire brief sits within Fusion42's coverage of Data Infrastructure.
◆ ◆ The Wire takeaway
The timeline and costs for small nuclear reactors to serve data centers just got longer and riskier. You face supply chain and regulatory boulders that could block your grid resilience plan, so look for backup power strategies that don’t hinge on unproven nuclear tech.
