SMRDB exists to expand public knowledge of small modular reactors and accelerate their path from design to deployment. We believe that widespread understanding of SMR technology is critical to solving the world's most pressing energy challenges.
The world faces an unprecedented energy dilemma. Global electricity demand is surging — driven by the explosive growth of AI and data centers, which are projected to consume 8% of US electricity by 2030. Vampire power from always-on devices drains billions of kilowatt-hours annually. Meanwhile, the climate crisis demands we eliminate carbon emissions from power generation.
Nuclear power produces zero direct carbon emissions during operation. A single SMR can displace hundreds of thousands of tons of CO₂ annually compared to natural gas.
Hyperscale data centers need 100+ MW of reliable, 24/7 baseload power. SMRs are ideally sized for co-location — providing clean, constant energy where it's needed most.
Modern SMR designs incorporate passive safety systems that shut down automatically without human intervention or external power. Many cannot physically melt down.
Unlike traditional reactors, SMRs are manufactured in factories and shipped to site — reducing construction time, cost overruns, and quality variability.
We also believe in transparency about the challenges. SMR development is expensive — first-of-a-kind costs can exceed $5 billion. Regulatory processes are slow and complex. Nuclear waste, while far smaller in volume than fossil fuel pollution, still requires long-term management. Public perception remains a barrier in many regions.
But the potential is transformative. SMRs can power remote communities, replace retiring coal plants, desalinate water, produce hydrogen, and provide the reliable baseload that intermittent renewables cannot. The goal of SMRDB is to make every piece of SMR data freely accessible — so researchers, policymakers, investors, and the public can make informed decisions about this critical technology.
