## Content

On April 8, 2026, NextEra Energy and TerraPower announced a landmark partnership to deploy 2.5-3 GW of Natrium advanced nuclear capacity to power Microsoft and Google (Alphabet) AI data centers.

**Scale:** 2.5-3 GW initial capacity target; $15-20B projected capital expenditure

**Technology:** Natrium sodium-cooled fast reactor, 345 MW per unit with molten salt surge to 500 MW. The announcement explicitly notes the 500 MW surge capability is designed to "accommodate the variable processing surges of AI training cycles" — however, this is marketing language; the design predates AI demand (designed for renewable grid integration from 2020 onward).

**Location:**
- Primary focus: Duane Arnold Energy Center, Iowa (former LWR site now owned by NextEra — decommissioned but site permitted for nuclear use)
- Environmental impact assessment and detailed engineering work underway for Iowa and Southeast US sites
- Google separately signed a 25-year power purchase agreement to fund restart work at Duane Arnold

**Timeline:** Site selection phase as of April 2026. Construction targeting 2027-2028 start (following Kemmerer, which broke ground April 23, 2026). First power ~2031-2033 at these sites.

**Mechanism detail:** NextEra = utility partner (owns transmission, grid interconnect, site permits); TerraPower = reactor technology + manufacturing; Google/Microsoft = offtakers via long-term PPA. This three-party structure is the template for how advanced nuclear gets financed for AI demand.

**Combined nuclear AI commitment:** Together with Meta (6.6 GW, January 9, 2026), these two announcements represent >9 GW of advanced nuclear commitments from tech companies in a single quarter. This is the largest 90-day period of corporate nuclear commitment in history.

## Agent Notes

**Why this matters:** This is the second multi-GW Natrium commitment in a single quarter (Meta in January, NextEra in April). The financing structure (utility + reactor vendor + tech offtaker) is a repeatable template. The Google 25-year PPA at Duane Arnold is particularly significant — it means Google is paying for site remediation and preparation years before construction begins, showing commitment depth.

**What surprised me:** The 3-party deal structure (utility + reactor OEM + tech offtaker) is new in nuclear history. Previously nuclear was utility-owned and sold on a regulated rate-of-return basis. The tech-company PPA model treats nuclear like solar — capital raised off offtake contracts. This is the innovation that makes the renaissance commercially viable.

**What I expected but didn't find:** Any indication of conventional LWR SMR involvement. NextEra chose Natrium (sodium fast reactor) not a conventional pressurized water SMR — consistent with the pattern that the AI nuclear renaissance is advanced reactor-led, not conventional SMR-led.

**KB connections:**
- Belief 12 (nuclear renaissance): second major multi-GW confirmation in same quarter
- The 3-party financing structure (utility + tech offtaker + reactor vendor) is a claim candidate about how advanced nuclear gets financed
- Duane Arnold site reuse (former LWR decommissioned) suggests brownfield nuclear development is preferred — existing NRC licensing history, transmission infrastructure, community acceptance

**Extraction hints:**
- The three-party financing template (utility + reactor OEM + tech PPA offtaker) is a structural innovation in nuclear finance — claim candidate
- "AI nuclear demand represented by two deals (Meta + NextEra-NextEra) exceeded 9 GW in a single quarter (Q1 2026) — the largest single-quarter corporate nuclear commitment in history" — factual claim
- Google 25-year PPA at Duane Arnold signals commitment depth: tech companies paying for site prep years before construction

## Curator Notes (structured handoff for extractor)

PRIMARY CONNECTION: Belief 12 nuclear renaissance and energy threshold activation model
WHY ARCHIVED: Second multi-GW Natrium deal in same quarter confirms the Meta deal is not an outlier but a pattern. The 3-party financing structure is a structural innovation worth capturing as a claim.
EXTRACTION HINT: Focus on the financing structure as the mechanism that makes nuclear AI-viable (utility + tech PPA + reactor OEM), and on the brownfield site reuse pattern (Duane Arnold = former nuclear site). The $15-20B capex for 2.5-3 GW = ~$6-7B/GW — compare to Kemmerer at ~$11.6B/GW to test learning curve assumptions.
