# NextEra-TerraPower Natrium Partnership
|
|
|
|
**Type:** Strategic partnership for advanced nuclear deployment
|
|
**Announced:** Final months of 2025, formalized by April 2026
|
|
**Scale:** 2.5-3 GW Natrium reactor deployment
|
|
**Capital:** $15-20 billion projected capex
|
|
**Offtakers:** Google and Microsoft AI datacenters
|
|
|
|
## Overview
|
|
|
|
NextEra Energy and TerraPower formed a partnership to deploy 2.5-3 GW of Natrium sodium-cooled fast reactors specifically to power Google and Microsoft AI datacenters. This represents one of the largest advanced nuclear commitments in the AI-driven nuclear renaissance.
|
|
|
|
## Technology
|
|
|
|
**Natrium Reactor Specifications:**
|
|
- 345 MW sodium-cooled fast reactor base capacity
|
|
- Integrated molten salt energy storage system
|
|
- Can boost output to 500 MW during peak demand
|
|
- First advanced nuclear plant to receive NRC Environmental Impact Statement for commercial deployment
|
|
|
|
## Target Sites
|
|
|
|
- **Duane Arnold, Iowa:** Existing nuclear facility site, considered a regulatory bellwether for SMR licensing
|
|
- **Southeast US locations:** Additional sites under evaluation
|
|
|
|
The Duane Arnold site selection is strategically significant as it leverages an existing licensed nuclear site, potentially accelerating regulatory approval compared to greenfield deployment.
|
|
|
|
## Economics
|
|
|
|
- Capital cost: Approximately $5-8 billion per GW
|
|
- 3-5x higher capex than renewables (solar ~$1-2B/GW, wind ~$1.5-2.5B/GW)
|
|
- Provides firm dispatchable power with integrated storage
|
|
|
|
## Timeline
|
|
|
|
- **2025 Q4:** Partnership formalized
|
|
- **2026 Q2:** Site selection phase, environmental impact assessments and detailed engineering underway
|
|
- **2026+:** Regulatory filings expected
|
|
|
|
## Strategic Significance
|
|
|
|
Investors have characterized Duane Arnold's success as determining "the pace of SMR licensing for the next decade," making this partnership a critical test case for advanced reactor deployment at existing nuclear sites.
