Thesis

Why this sector matters to investors right now. Structural, not market timing.

Civilian nuclear power entered its first sustained policy and capital tailwind since the 1970s, anchored by three simultaneous structural shifts. First, hyperscaler demand for 24/7 carbon-free firm power converted nuclear from a stranded asset class into the most valuable kilowatt-hour in the US power stack: Microsoft + Constellation signed a 20-year PPA in September 2024 to restart Three Mile Island Unit 1 (renamed Crane Clean Energy Center, 835 MW, ~1.6 billion-dollar refurbishment, 2027 to 2028 target restart); Amazon + Talen took Susquehanna behind-the-meter for 960 MW in March 2024 (FERC ALJ rejected the ISA amendment November 2024, restructured to front-of-the-meter 2025); Google + Kairos contracted up to 500 MW of KP-FHR molten-salt reactors in October 2024 with first delivery by 2030; Amazon + X-energy + Energy Northwest committed to 5 GW of Xe-100 SMRs by 2039; Meta + Constellation signed 1.121 GW at Clinton in June 2025; and AWS + Vistra Comanche Peak closed a binding 20-year PPA for 1,200 MW in September 2025 (CEO Jim Burke named AWS in the Vistra Q4 2025 earnings release dated February 26, 2026). Second, US policy aligned around nuclear in a way it has not since the Atomic Energy Act of 1954: the IRA section 45U production tax credit (15 to 30 dollars per MWh), the Bipartisan Infrastructure Law Civil Nuclear Credit Program (6 billion dollars), the Prohibiting Russian Uranium Imports Act (Public Law 118-62, signed May 13, 2024), the ADVANCE Act (Public Law 118-67, signed July 9, 2024), the NRC Part 53 final rule (issued March 26, 2026, effective April 29, 2026), and the DOE Loan Programs Office Holtec Palisades commitment (1.52 billion dollars, September 2024) and Constellation Crane CEC closed loan (1 billion dollars, November 18, 2025) collectively reset US nuclear from regulatory hostility to active industrial-policy support. Third, the fuel-cycle bottleneck became visible to capital: Rosatom controls roughly 46 percent of global enrichment SWU capacity and 70 percent of reactor exports outside China, exposing the West to a 4 to 10 year capacity rebuild (Centrus AC100M first kg October 2023; Urenco USA expansion 2027 to 2028; DOE HALEU Consortium 700 million-dollar January 2024 awards).

The investible question is which capital structure captures which structural shift. Existing nuclear operators (Constellation, Vistra, Talen, Duke, Southern, NextEra) carry uprated PPA revenue plus the IRA PTC floor; their 2024 to 2025 stock performance reflects the rerating. SMR pure-plays (NuScale, Oklo, NANO Nuclear, BWXT, Centrus, GE Vernova, Rolls-Royce) carry the FOAK execution and licensing-pace bet at venture-style valuations. Uranium and fuel-cycle equities (Cameco, Kazatomprom, Centrus, NexGen, Energy Fuels, Boss, Paladin, Sprott Physical Uranium Trust) carry the structural supply-deficit bet against a price band that ranged from approximately 18 dollars per pound in 2016 to approximately 107 dollars per pound in early 2024. Private fusion (Commonwealth Fusion Systems, Helion, TAE, Pacific Fusion, plus a 17-company FIA-tracked roster) carries a separate over-the-horizon thesis: NIF crossed the scientific Q greater than 1 threshold on December 5, 2022 (3.15 MJ output from 2.05 MJ laser input), the NRC issued a fusion-specific 10 CFR Part 30 regulatory framework on April 14, 2023 (NOT Part 50/52), and two binding fusion electricity-purchase agreements now exist (Microsoft + Helion 50 MW May 2023; Google + Commonwealth Fusion Systems 200 MW ARC Virginia June 2025). The FIA 2024 Global Industry Report shows 70 percent of fusion developers expect commercial deployment by the end of 2035; the median external view sits in the 2040 to 2050 range. Each lens answers a different investment question, and the Nuclear sector page is organized around all four.

Structural drivers

Forces that shape long-run demand and economics. Each driver is sourced.

•Hyperscaler PPA wave. Six binding plus two near-binding nuclear power agreements (Microsoft-Constellation TMI restart Sep 2024, Amazon-Talen Susquehanna BTM Mar 2024 restructured 2025, Google-Kairos up to 500 MW Oct 2024, Amazon-X-energy 5 GW Oct 2024, Meta-Constellation Clinton 1.121 GW Jun 2025, AWS-Vistra Comanche Peak 1,200 MW Sep 2025; plus second binding fusion PPA Google-CFS 200 MW Jun 2025). Sources: Vistra 8-K Feb 26 2026 EX-99.1 (https://www.sec.gov/Archives/edgar/data/1692819/000119312526073364/d21122dex991.htm); Constellation press Sep 20 2024; Helion press May 10 2023.
•US policy stack reset 2022 to 2026. IRA section 45U production tax credit (15 to 30 dollars per MWh for existing nuclear, 2024 to 2033). Bipartisan Infrastructure Law Civil Nuclear Credit Program ($6B). Prohibiting Russian Uranium Imports Act PL 118-62 signed May 13 2024 (phases Rosatom imports out by 2028 with DOE waivers through 2027). ADVANCE Act PL 118-67 signed July 9 2024 (NRC modernization, fee reform, advanced reactor incentives). NRC Part 53 final rule issued March 26 2026, effective April 29 2026 (risk-informed licensing for non-LWR designs). DOE LPO Holtec Palisades $1.52B Sep 2024; Constellation Crane CEC $1B Nov 18 2025 (first concurrent conditional+close under the Trump administration). Sources: GovInfo PDFs for PL 118-62 and PL 118-67; NRC press; DOE LPO portfolio.
•Fuel-cycle bottleneck and HALEU supply. Rosatom controls ~46 percent of global enrichment SWU capacity and ~70 percent of reactor exports outside China. Western HALEU capacity (Centrus AC100M Piketon first kg Oct 2023, 16-cascade target ~6,000 kg HALEU per year; Urenco USA NM expansion 2027 to 2028; Orano planning) lags advanced-reactor demand by 5 to 10 years against ~150 metric tons cumulative 2030 to 2035 need. DOE HALEU Consortium awarded ~$700M to six Western producers in January 2024. Sources: WNA enrichment library; Centrus IR; DOE press release January 2024.
•US existing fleet operates at structural premium. 94 operating US reactors at approximately 92 percent capacity factor (highest of any generation type; gas ~57 percent, wind ~33 percent, solar ~25 percent). Vogtle Units 3 and 4 commissioned July 2023 and April 2024 (~$35B all-in, AP1000, 2.2 GW), the first new US large reactors since Watts Bar 2 in 2016. Palisades and Crane Clean Energy Center (TMI-1) restarts targeted 2026 to 2028. Approximately 30+ SLR applications extend operating licenses from 60 to 80 years. Sources: EIA Electric Power Monthly; NRC operating reactor status; IAEA PRIS.
•China and Korea export competition. China operates 60 reactors with 30+ under construction; Hualong One and CAP1000 standardized designs delivering ~$2,500 to $3,500 per kW overnight in 5 to 6 year build cycles. South Korea's APR1400 (KEPCO) demonstrated UAE Barakah 1 through 4 (commercial 2020 to 2024) and won the Czech Dukovany 5 contract ($18 billion, August 2024). Western Vogtle FOAK at ~$16,000 per kW over 14 years quantifies the 4 to 5x cost-time gap that Western policy is now attempting to close. Sources: WNA country profiles; IAEA PRIS; OECD NEA cost data.
•SMR and advanced reactor pipeline at NRC. NuScale 50 MWe variant received first US SMR design certification January 2023; 77 MWe variant in standard design approval. Kairos Hermes received first non-LWR construction permit December 2023. GE Vernova BWRX-300 selected for Ontario Power Generation Darlington (target 2028 to 2029). Westinghouse AP300 (300 MWe), TerraPower Natrium 345 MWe at Kemmerer Wyoming (NRC construction permit pending), X-energy Xe-100 80 MWe (Dow Seadrift and Energy Northwest 5 GW). Rolls-Royce SMR won the UK competition in Q3 2025. Sources: NRC docket; Third Way Advanced Nuclear Map; company filings.
•DOE Reactor Pilot Program. Selected 11 projects from 10 companies in August 2025 with a July 4 2026 criticality target (widely judged aspirational; Energy Secretary Wright publicly stated only one or two might meet the date). Three Preliminary Design Safety Assessments (PDSA) granted through Q1 2026 (Radiant February, Valar March, Aalo March). Establishes a DOE-led parallel licensing path complementing NRC. Source: DOE Office of Nuclear Energy press releases.
•Fusion entered commercial-PPA territory. NIF achieved scientific ignition (Q_laser > 1) on December 5 2022 (3.15 MJ output from 2.05 MJ laser input). The NRC issued a fusion-specific 10 CFR Part 30 regulatory decision April 14 2023 (NOT Part 50/52 utilization facility), a major enabling decision for US private fusion commercialization. Two binding fusion electricity-purchase agreements exist as of mid-2026: Microsoft + Helion 50 MW (May 10 2023, 2028 target) and Google + Commonwealth Fusion Systems 200 MW ARC Virginia (June 30 2025). Cumulative private fusion funding approximately $7.7 billion per the FIA 2024 Global Industry Report. Sources: LLNL ignition press; NRC official Apr 14 2023 decision; Helion + CFS press; FIA Global Industry Report 2024.
•Uranium market dynamics. U3O8 spot price ranged from approximately $18 per pound in 2016 to approximately $107 per pound in January 2024 (UxC weekly broker average). Cycle drivers: post-Fukushima inventory unwind 2011 to 2017; Sprott Physical Uranium Trust launch July 2021; Cigar Lake flood June 2021; Niger coup July 2023; Kazatomprom production cut August 2024 (-17 percent due to sulfuric acid supply constraints). Top producers by share: Kazakhstan ~40 percent (Kazatomprom KAP.IL), Canada ~13 percent (Cameco CCJ), Namibia ~12 percent, Australia ~9 percent. Sources: WNA annual reports; Cameco quarterly market reports; Kazatomprom IR.

Structural risks

Forces that could compress demand, change economics, or break the thesis.

•Hyperscaler PPA structures face FERC and ISO challenges. The original Talen + Amazon Susquehanna BTM amendment was rejected by a FERC Administrative Law Judge on November 1, 2024 (cited as unjust cost shift to other PJM ratepayers); restructured to front-of-the-meter network service in 2025. Similar BTM proposals at other nuclear plants face the same regulatory questions about cost allocation to grid-connected ratepayers. Source: FERC eLibrary Docket ER24-2172.
•SMR FOAK timeline slippage and developer concentration. NuScale Carbon Free Power Project at UAMPS cancelled November 8 2023 after cost growth. Last Energy 2025 to 2026 commercial claims are widely disputed by independent analysts. Oklo 2027 to 2028 FOAK and NANO Nuclear near-term timelines flagged as 'independently implausible' in the data. Only a subset of the 17 NRC-tracked developers will reach commercial operation by 2030.
•HALEU supply lags advanced-reactor demand by 5 to 10 years. Western producers (Centrus AC100M, Urenco USA NM, Orano planning) need to scale from kilograms to metric tons by 2030 to 2035 against approximately 150 MT cumulative demand. The gap forces either Russian supply continuation under DOE waivers (through 2027) or program-by-program HALEU procurement risk for SMR developers. Source: DOE HALEU Availability Program; Centrus IR.
•Construction cost remains Western achilles heel. Vogtle 3+4 final all-in cost approximately $35 billion against original 2008 estimate of $14 billion (2.5x). Hinkley Point C trending to GBP 47 billion (~$60 billion) against original GBP 24 billion (2.4x). China Hualong One and Korean APR1400 build at $2,500 to $4,500 per kW in 5 to 6 years vs Western FOAK $14,000 to $16,000 per kW over 14 years. SMR standardization is the structural answer; it has not yet been demonstrated at commercial scale.
•FY2026 to FY2027 federal nuclear budget direction. Trump administration EOs (May 23 2025) signaled support but downstream OMB implementation remains in progress. Specific program funding (ARDP extensions, NRIC, HALEU follow-on awards, LPO conditional loans) is appropriation-cycle dependent and subject to continuing resolution risk.
•Russia exposure transition risk. PRUIA phases Rosatom imports out by 2028 with DOE waivers available through 2027. France retains ~25 to 30 percent enrichment exposure to Rosatom; Hungary, Slovakia, Bulgaria, Finland operate VVER fleets that depend on Russian fuel through 2030 absent fuel-pivot to Westinghouse alternative LEU. The political will to maintain the ban under stress (e.g., enrichment-capacity crunch) is untested.
•Public opinion remains accident-vulnerable. US support sits at 56 percent favor per Gallup 2024 (up from 43 percent in 2016), but one significant incident at any operating reactor globally could re-polarize policy. The TMI 1979 and Fukushima 2011 precedents show the public-opinion sensitivity at scale. State-level moratoriums (12 active or de facto, 5 lifted including Illinois December 2023, West Virginia 2022, Kentucky 2017, Wisconsin 2016, Connecticut 2022) remain a structural ceiling in California and New York absent legislative change.
•Fusion commercial timing remains over-the-horizon. ITER first plasma slipped to 2034 to 2035 per November 2024 ITER Council baseline revision (DT operation now 2039+); 14-year cumulative slip from the original 2020 target. NIF wall-plug Q is approximately 0.01 versus the approximately 3+ wall-plug Q required for commercial viability. Helion has previously missed Polaris timeline commitments; the Microsoft PPA includes performance ramps. Capital availability across the 17 FIA-tracked private fusion developers is sufficient for science but not for grid-scale commercialization, which requires at least one binding pilot-plant construction commitment that does not yet exist.

Competitive landscape

How to think about the players. Framing along axes (pure play vs diversified, incumbent vs challenger, etc). Not stock picking.

The investible universe sorts into five archetypes.

1. US existing-fleet operators. Constellation Energy (CEG, ~21 GW nuclear, largest US operator; Crane CEC restart with Microsoft PPA), Vistra (VST, ~6 GW including Comanche Peak with 1,200 MW AWS PPA Sep 2025; expanded post-Energy Harbor 2024 acquisition), Talen Energy (TLN, ~2.5 GW Susquehanna; Amazon Cumulus campus + restructured FOTM PPA), Duke Energy (DUK, ~10.7 GW; Amazon SMR study at North Anna), Southern Company (SO, ~5 GW including Vogtle 3+4), NextEra Energy (NEE, ~7 GW; Duane Arnold restart program target Q1 2029), PSEG (PEG), Dominion Energy (D). Stable utility cash flow plus IRA 45U PTC floor plus hyperscaler PPA premium. Mature dividend policy and rate-base growth.

2. US SMR and advanced reactor pure-plays. NuScale Power (SMR; 77 MWe VOYGR variant in SDA), Oklo (OKLO; Aurora liquid-metal fast reactor, SPAC May 2024, Sam Altman backed), NANO Nuclear Energy (NNE; microreactors Zeus, Odin, Kronos, IPO May 2024, pre-revenue), BWX Technologies (BWXT; civilian-power slice covers TRISO fuel + advanced reactor components + HALEU downblend; naval segment out of scope here), Centrus Energy (LEU; only US operator with HALEU production today). Venture-style economics with FOAK execution risk and NRC licensing-pace dependency.

3. Reactor OEMs and EPCs. GE Vernova (GEV; BWRX-300 SMR), Rolls-Royce Holdings (RR.L; 470 MWe SMR, UK competition winner Q3 2025), Mitsubishi Heavy Industries (7011.T; ATMEA, BWR), Doosan Enerbility (Korean reactor forgings), KEPCO E&C (Korean APR1400 design). Westinghouse (private, Brookfield + Cameco JV since Nov 2023; AP1000, AP300 SMR, eVinci microreactor). Framatome (private, EDF subsidiary; EPR2). Industrial-cycle exposure to fleet additions and SMR FOAK contracts.

4. Uranium and fuel cycle. Producers: Cameco (CCJ, ~17 percent global production share; 49 percent of Westinghouse), Kazatomprom (KAP.IL, ~40 percent global share). Developers: NexGen Energy (NXE, Arrow project), Denison Mines (DNN), Boss Energy (BOE.AX), Paladin Energy (PDN.AX). US-focused producers: Uranium Energy (UEC), Energy Fuels (UUUU), Ur-Energy (URG). Holding vehicle: Sprott Physical Uranium Trust (U-UN.TO / SRUUF, approximately 81 million pounds U3O8 inventory, $7.1B market cap May 2026). Centrus (LEU) for enrichment. Price-cycle exposure with structural supply deficit thesis.

5. Private fusion developers. Commonwealth Fusion Systems (MIT spinout; SPARC + ARC tokamak, HTS magnets, Google + ARC Virginia 200 MW PPA June 2025; CFS Series B2 August 28 2025 ~$863M consortium round including Nvidia, Google, Counterpoint, Japanese consortium). Helion Energy (pulsed FRC, D-He3 fuel; Microsoft 50 MW PPA May 2023). TAE Technologies (FRC with neutral beam heating, p-B11 fuel). Tokamak Energy, General Fusion, Pacific Fusion ($900M Series A Oct 2024 led by General Catalyst), Zap Energy, Marvel Fusion, Realta Fusion, Type One Energy, Xcimer Energy, Avalanche Energy, Proxima Fusion, Renaissance Fusion, HB11 Energy, Focused Energy, First Light Fusion (pivoted Nov 2024 to licensing). Total approximately 20 private companies tracked; Pulsar Fusion and Helicity Space are propulsion-focused and out of civilian-power scope. All private; no public-market pure-play fusion exists as of mid-2026.

Cross-cutting framing: existing-fleet operators carry the cleanest near-term cash flow (uprated PPAs plus PTC); SMR pure-plays carry the highest-conviction execution risk against the largest addressable opportunity; reactor OEMs are cyclical with SMR order-book optionality; uranium and fuel-cycle equities carry the structural supply-deficit thesis least correlated to hyperscaler PPA timing; private fusion is over-the-horizon with two binding PPAs and a 7-billion-dollar cumulative capital base. The single most concentrated near-term risk is FERC and ISO treatment of BTM and large-load co-located deals (the Susquehanna ALJ precedent); the single most concentrated near-term opportunity is the HALEU supply-demand gap closing through Centrus and Urenco USA expansion.

Key metrics to watch

The operational and financial metrics that matter most in this sector. Each one names its source and update cadence.

Metric	Source	Frequency	Why it matters
Global nuclear electricity generation (TWh per year)	Energy Institute Statistical Review of World Energy, Our World in Data, IAEA PRIS	Annual	Single-line measure of the sector's total output. 2,777 TWh in 2024; 2,812 TWh in 2025 (record). Compares against the 2,725 TWh pre-Fukushima peak (2010) and the 2,432 TWh post-Fukushima trough (2012). The structural recovery is now confirmed.
US fleet capacity factor	EIA Electric Power Monthly (https://www.eia.gov/electricity/monthly/)	Monthly (6-week lag)	Approximately 92 percent annual fleet weighted average; the highest of any generation type (gas ~57 percent, wind ~33 percent, solar ~25 percent). Material dips would indicate fleet aging issues; sustained levels confirm the operating economics that underpin existing-fleet thesis.
Uranium spot price (U3O8 dollars per pound)	UxC weekly broker average, Cameco quarterly market reports, Numerco, TradeTech	Weekly spot, quarterly term contracts	Cycle range approximately $18 in 2016 to approximately $107 in January 2024. Spot is approximately 10 to 20 percent of annual demand; utilities source approximately 80 percent through long-term term contracts. Both prices matter for upstream equity thesis.
Confirmed hyperscaler nuclear PPA capacity and structure	Company press releases plus SEC 8-K filings (Constellation, Vistra, Talen, Amazon, Microsoft, Google, Meta), FERC eLibrary	Continuous (event-driven), monthly synthesis	Six binding fission PPAs at approximately 4.7 GW combined plus two binding fusion PPAs (Microsoft-Helion 50 MW, Google-CFS 200 MW). New deals reset the demand-curve assumptions. PPA versus MoU classification is the critical filter against headline noise.
SMR and advanced reactor developer NRC pipeline position	NRC New Reactor Pre-Application Activities and Combined License Application docket pages	Continuous (event-driven), quarterly synthesis	17 developers tracked. Pipeline progression (pre-application -> topical -> SDA -> COL -> construction permit) is the single-line measure of FOAK-2028-to-2032 realism. NuScale 77 MWe SDA decision and Kairos Hermes construction permit Dec 2023 are the foundational data points.
HALEU production cumulative tons MT per year	DOE HALEU Availability Program announcements; Centrus IR quarterly; Urenco USA, Orano, BWXT, GLE Silex IR	Quarterly	Approximately 150 MT cumulative demand 2030 to 2035 versus current Western production at kilogram scale (Centrus AC100M first kg Oct 2023; 16-cascade target ~6,000 kg per year). The single most binding supply constraint for advanced-reactor commercialization.
Vistra, Constellation, Talen, NextEra hyperscaler-PPA revenue cadence	Quarterly 10-Q + 10-K filings; earnings call transcripts; 8-K event filings	Quarterly	Tracks transition of headline PPA announcements into recognized contract revenue. Comanche Peak deliveries begin Q4 2027 ramping to full 1,200 MW by 2032; Crane CEC target 2027 to 2028; Clinton Q2 2027. The 2027 fiscal year is the first major proof point.
Fusion industry private cumulative funding and FIA survey results	Fusion Industry Association Global Industry Report (annual September to October release)	Annual + quarterly round tracking	Approximately $7.7 billion cumulative private funding through the 2024 FIA report. The FIA survey commercial-timing distribution (70 percent expect deployment by end of 2035; majority external view 2040 to 2050) is the cleanest single-line measure of industry self-assessment versus expert consensus.

What would change the view

Conditions or evidence that would invalidate the thesis or materially shift the risk picture.

•FERC or ISO reverses the BTM-PPA precedent (Susquehanna ALJ ruling). A favorable BTM regulatory framework would reset the addressable opportunity for the next wave of hyperscaler nuclear deals.
•NRC Part 53 implementation pace materially exceeds (or lags) expectations through 2026 to 2027. The single most consequential variable on SMR FOAK-2030 realism.
•China or Korea (KEPCO) wins a major Western SMR competition. Would reset the Western reactor-OEM thesis and accelerate the cost-gap closure timeline.
•Major nuclear safety incident anywhere globally. One operating-reactor accident would re-polarize US and European public opinion regardless of cause. The TMI 1979 and Fukushima 2011 precedents define the policy-sensitivity ceiling.
•Rosatom enrichment supply disruption (sanctions tightening or unilateral cut). Forces accelerated Western HALEU and LEU buildout; near-term price spike followed by capacity rebuild.
•Uranium spot price breakdown below $50 per pound (would compress upstream equity thesis) or breakout above $150 per pound (would accelerate Western supply response and reset producer equity multiples).
•Helion fails Polaris electricity demonstration (third missed timeline). Would reset the Microsoft fusion-PPA timeline and trigger broader skepticism of near-term fusion commercialization claims.
•ITER announces another multi-year schedule slip beyond the November 2024 baseline. Would push the public-program first-of-a-kind reference into the late 2030s and reset commercial-fusion adjacent expectations.
•A second major hyperscaler signs a binding fission SMR offtake (not just MoU). Would convert SMR developer valuations to PPA-backed forward economics rather than venture-style narrative.
•Trump administration shifts away from nuclear support in FY2027 or FY2028 OMB requests. Would reverse the policy-stack tailwind anchoring the existing-fleet thesis.

What we are not covering

Sub-areas, technologies, or companies we are deliberately excluding from the analysis, and why.

•Naval nuclear (Columbia-class SSBN, Virginia-class SSN, Sentinel ICBM, B-21 nuclear-capable bomber). Tracked in the Defense sector. BWXT naval revenue (~70 percent of parent revenue) is explicitly excluded from this sector's BWXT row.
•Medical radioisotopes (Mo-99, Lu-177, Ac-225). Adjacent to nuclear technology but a different end market.
•Fusion propulsion (Pulsar Fusion, Helicity Space). Targets spacecraft propulsion rather than grid power. Excluded from the Tab 5 Fusion roster.
•Weapons-grade material production and tritium for weapons. Government-only, not investable, and not in scope.
•Project Pele DoD microreactor program (BWXT). DoD-only; civilian-applicable SMR business (BANR, TRISO fuel) is in scope.
•Geothermal as a competing baseload technology. Different sector, but tracked as a substitute risk in the bull-vs-bear synthesis.
•Battery-storage as a competing firm-power alternative. Tracked in the Battery sector; cross-referenced here as a substitution risk for SMR economics at certain duty cycles.
•Pure cybersecurity software firms that serve the nuclear industry as customers (e.g., specialized nuclear OT security). Adjacent but not procurement-cycle exposure in the nuclear sense.

Change log

2026-05-16Initial publication. All ten required SOP components populated using sourced 2024 and 2025 full-year plus 2026 year-to-date data. Primary sources: Vistra Corp 8-K Sep 29 2025 (Comanche Peak PPA disclosure) and Feb 26 2026 Q4 2025 earnings release EX-99.1 (AWS-named); Constellation Energy press Sep 20 2024 (Microsoft Crane CEC); Helion Energy press May 10 2023 (Microsoft fusion PPA); LLNL official ignition shot summary Dec 5 2022; NRC official Apr 14 2023 fusion regulatory decision; ADVANCE Act PL 118-67 and PRUIA PL 118-62 via Congress.gov GovInfo PDFs; NRC Part 53 final rule Mar 26 2026 and effective Apr 29 2026; DOE LPO Holtec Palisades + Constellation Crane CEC announcements; EIA Electric Power Monthly for US capacity factor; Energy Institute Statistical Review of World Energy and Our World in Data for global nuclear generation TWh 1990 to 2025; UxC, Cameco quarterly market reports, Sprott Physical Uranium Trust for uranium spot; FIA Global Industry Report 2024 for fusion private funding totals and commercial-timing survey; IAEA PRIS for global reactor counts (60 China, 57 France, 94 US); WNA country profiles for build pipeline. All facts verified against primary sources via dedicated 2026-05-16 browser-automation editorial pass. Two binding hyperscaler fusion PPAs now exist (Microsoft + Helion 50 MW; Google + CFS 200 MW); China reactor count is 60 (was 56 / 57 in earlier passes); NRC Part 53 final rule is locked; ITER baseline revision is November 2024 (not July 2024). Civilian power scope only: naval, ICBM, weapons, medical isotopes, fusion propulsion all excluded.

Unresolved questions

•Whether FERC or ISO regulatory framework for behind-the-meter and large-load co-located PPAs settles in favor of or against hyperscaler-nuclear deal structures. The Susquehanna ALJ precedent is the leading case.
•NRC Part 53 implementation pace through 2026 to 2027. Whether the licensing modernization translates into measurable FOAK-2030 SMR construction permits.
•DOE Reactor Pilot Program July 4 2026 criticality target outcome. Binary signal on DOE-led parallel licensing realism.
•Western HALEU production scaling from kilograms to metric tons by 2030. Centrus AC100M cascade ramp, Urenco USA expansion, Orano planning, BWXT downblend cadence.
•Vistra Comanche Peak Q4 2027 first deliveries to AWS. The first major nuclear hyperscaler PPA proof point.
•Helion Polaris electricity demonstration outcome (target 2025 to 2026 revised). The first private-sector net-electricity claim if achieved.
•Whether a second major hyperscaler signs a binding fission SMR offtake before 2027. The trigger for SMR developer valuation rerating from venture to PPA-backed.
•Oracle SMR campus counterparty (utility partner and reactor vendor). Currently unnamed in any SEC filing through Q3 FY26 10-Q (March 11 2026).
•China and Korea SMR export competition. Whether KEPCO APR300 or Chinese ACP100 Linglong wins a Western market deployment before US SMRs reach FOAK.
