Why it matters: On-site systems can shorten time-to-power and protect critical loads when grid upgrades are delayed or unreliable.

Why now: Data-center power constraints are increasing interest in modular power, backup capacity and integrated on-site infrastructure.

Shared demand driver: Large-load owner spending to accelerate reliable power availability ahead of or alongside grid upgrades.

Shared buyer or budget: Data-center developer and industrial-site power-resilience budgets

Nuclear Fuel and HALEU Enrichment

Theme Heat 74 of 100 — high, measured 2026-10-09. Fuel-cycle and enrichment capacity are strategically critical for nuclear expansion and energy security. Near-term transmission is narrower than generation contracts, but scarcity and policy support remain strong.

Uranium, enrichment and fuel-fabrication suppliers—especially HALEU-capable capacity—are critical upstream constraints on dispatchable nuclear power for large loads.

Why it matters: Every reactor restart, life extension and SMR deployment adds cumulative fuel demand; enrichment (especially domestic HALEU) is a scarce toll-collector position with national-security backing.

Why now: Centrus is the only licensed domestic HALEU supplier with a ~$3.6bn enrichment order book; BWXT won a ~$1.5bn NNSA contract for defense enrichment; uranium recovered to the mid-$80s/lb with analysts projecting further upside.

Shared demand driver: Rising cumulative demand for enriched uranium and HALEU fuel from reactor restarts, life extensions and advanced-reactor deployment, plus federal supply-chain reshoring

Shared buyer or budget: Utility fuel-procurement contracts, reactor developers and US government/DOE-NNSA enrichment programs

SMR and Microreactor Developers

Theme Heat 62 of 100 — moderate, measured 2026-10-09. SMR and microreactor developers benefit from the firm-power narrative, but most remain pre-revenue and dependent on lengthy licensing and construction execution. Strategic necessity is high while demonstrated commercial momentum is lower.

Pre-revenue developers of small modular and microreactors targeting dedicated firm power for data centers, industrial campuses and other concentrated loads.

Why it matters: If data-center operators take the energy problem into their own hands, dedicated microreactors become the local baseload solution; direct hyperscaler agreements are already validating the demand pull even before reactors are built.

Why now: Oklo announced an upsized 75 MWe design and a Meta 1.2 GW deal for southern Ohio; NuScale, the only NRC-certified SMR, has a TVA-linked 6 GW pipeline with a PPA expected to close by year-end 2026 - both catalysts landed across 2026.

Shared demand driver: hyperscaler and data-center operator demand for dedicated, carbon-free baseload power via direct power-purchase and prepayment agreements with reactor developers

Shared buyer or budget: hyperscaler power-procurement commitments (e.g. Meta, Switch) funding dedicated nuclear baseload
