U.S. Nuclear Capacity Expansion Industry Research Report 2026: $57B Investment Outlook Across Uprates, SMRs & Restarts 2025-2035 - The Evidence Asymmetry Distorts Capital Allocation
Dublin, Feb. 27, 2026 (GLOBE NEWSWIRE) -- The "U.S. Nuclear Capacity Expansion Market: $57B Investment Outlook Across Uprates, SMRs & Restarts (2025-2035)" report has been added to ResearchAndMarkets.com's offering.
The report sizes the market across three scenarios (conservative: $24-34B / 7 GW; base: $45-70B / 12 GW; optimistic: $72-123B / 18 GW) using triangulated methodology: bottom-up from announced projects and NRC pipeline data, top-down from federal targets including Executive Order 14302's 5 GW uprate directive, and cross-referenced against Reuters Events/Bloomberg Intelligence and IEA projections. Segmentation covers pathway type, buyer category (hyperscalers, regulated utilities, competitive generators, independent developers), and deployment timeline.
The U.S. nuclear capacity expansion market represents an estimated $57 billion investment opportunity through 2035, as the industry enters its first multi-pathway expansion cycle in four decades. This report provides a comprehensive head-to-head comparative analysis of the three primary pathways driving near-term capacity additions - nuclear fleet uprating, reactor restarts, and small modular reactors (SMRs) - with additional coverage of new large reactor construction as longer-term context. Each pathway is evaluated by cost per kilowatt, timeline to operation, regulatory readiness, and evidence quality.
This analysis reveals a systematic evidence asymmetry at the heart of nuclear investment decisions. The NREL Annual Technology Baseline incorporates 35 bottom-up cost estimations for advanced reactor designs despite zero completed U.S. commercial SMR projects, while nuclear uprate costs remain largely unstudied despite 172 NRC-approved projects adding 8 GW to the grid over five decades. The analysis finds that fleet uprating delivers 39-50% of projected near-term capacity additions at under a quarter of total capital expenditure - a 2-4x capital efficiency advantage over SMR deployment at current projected costs.
The report includes 10 charts and figures, 8 data tables, 12 company profiles, and a detailed methodology appendix grading evidence from completed projects through unvalidated company claims.
