With a resurgence in nuclear energy support fueled by technology firms seeking reliable power for data centers, the longstanding issue of how to safely store nuclear waste has resurfaced as a pressing concern in the US. While nuclear energy production grows, the country still lacks a permanent disposal plan for its accumulating radioactive waste.
- US produces ~2,000 metric tons of nuclear waste annually with no permanent storage
- Deep geological repositories are global best practice, yet US project stalled since 2011
- New nuclear growth driven by tech demand highlights urgency to manage future waste
What happened
Nuclear energy has found renewed political and commercial support in the United States, largely driven by tech companies’ demand for consistent, large-scale electricity. Despite this momentum, the US nuclear industry still lacks a long-term plan for handling the roughly 2,000 metric tons of high-level nuclear waste generated each year. Used fuel is currently stored on-site in temporary facilities but these solutions were never designed for permanent containment.
Globally, deep geological repositories—subsurface cavities hundreds of meters underground—are recognized as the safest permanent storage method. Finland is leading with its soon-to-be-operational underground repository, and France operates an advanced reprocessing system alongside plans for a dedicated storage repository. Although Yucca Mountain was designated as the US solution over three decades ago, political resistance and funding cuts have halted its development, leaving waste storage challenges unresolved amid an expanding industry.
Why it matters
International peers demonstrate that progress is achievable through sustained planning and institutional commitment. Finland’s multi-decade effort and France’s integrated reprocessing and storage model provide practical frameworks that the US could emulate. A failure to address the waste storage issue proactively could undermine the economic and environmental benefits nuclear power promises, especially as major energy consumers increasingly back the technology.
What to watch next
Attention is turning toward calls for a new governmental or quasi-governmental agency dedicated solely to nuclear waste management in the US, modeled after similar organizations in Finland, Canada, and France. This entity could centralize responsibility, streamline funding, and advance site selection and construction of a permanent repository. Political will and public engagement will be critical to overcoming past opposition and reigniting progress on this front.
