Small Modular Reactor Commercialization Act of 2025
Congress targets faster small nuclear reactor rollout by expanding size limits and protecting funding eligibility
Stalled
No legislative action in over 90 days.
Legislative Progress
Key Points
- Congress would raise the size limit used to define a “small modular reactor” from 300 to 500 megawatts, letting larger designs count as “small.”
- The Energy Department would have to treat more efficient reactors as eligible under certain nuclear liability/capacity rules by increasing allowed output and combined site capacity.
- The Nuclear Regulatory Commission and the Energy Department would have to update their public guidance so their “small” and “micro” reactor definitions match this bill.
- The Energy Department could not block funding help for grid-scale small modular reactor projects just because one reactor unit is between 50 and 500 megawatts.
- The Energy Department would set up a multi-agency working group to speed commercialization, manufacturing, and workforce planning for these reactors, with yearly reports through 2030.
