Supply-chain research brief
Map HALEU conversion, enrichment, deconversion, fuel fabrication, transport, and reactor demand anchors across the advanced nuclear fuel cycle.
Market map
Advanced reactor deployment is increasingly a fuel-cycle problem, not only a reactor-design problem. Many designs need HALEU, but usable supply requires several separate steps: uranium conversion to UF6, enrichment, deconversion or metallization, fuel fabrication, packaging, transport, and qualified customer programs that can absorb the material.
The tightest bottleneck can move across the chain. Enrichment capacity gets the headlines, but conversion, deconversion, metal-fuel preparation, TRISO manufacturing, nuclear graphite, and licensed transport packages can each delay deployment. Constraint Alpha separates direct supply from demand-side validation so a reactor developer is not mistaken for a merchant fuel supplier.
This directory uses the supplied deep-research reports as a seed set and keeps the distinction between verified primary-source evidence, sourced but early claims, and speculative option value. Scores are research-priority inputs, not recommendations; licensing, financing, geopolitics, offtake, and reactor schedules still need primary-source follow-up.

LEU · NYSE American
Supply-chain layerHALEU enrichment
Centrus is one of the clearest Western HALEU supply-chain bottlenecks: its Piketon American Centrifuge Plant has produced NRC-licensed HALEU and passed the 900 kg DOE delivery milestone.
BWXT · NYSE
Supply-chain layerDeconversion, feedstock processing, and TRISO inputs
BWXT combines HALEU feedstock processing, downblending, deconversion exposure, and TRISO-linked fuel capabilities, making it a rare bridge between government fuel programs and advanced-reactor fuel forms.
SOLS · Nasdaq
Supply-chain layerUF6 conversion
Solstice is a high-bottleneck, lower-pure-play conversion node because Metropolis Works is positioned as the only U.S. UF6 conversion facility, a prerequisite before enrichment can scale.
SLX · ASX
Supply-chain layerLaser enrichment technology
Silex is a technology-option name on future enrichment capacity through GLE and laser enrichment, with potentially high bottleneck value if the platform reaches commercial scale.
SGL · XETRA
Supply-chain layerNuclear graphite
SGL Carbon is a second-order HALEU bottleneck because qualified nuclear graphite can constrain HTGR and TRISO-based reactor deployment even when fuel supply is available.

Questions
HALEU requires specialized enrichment, conversion, deconversion, fuel-form processing, transport, and licensing capacity. A shortage at any step can delay advanced reactor deployment.
No. Some companies are fuel suppliers or processors, while others are demand anchors whose reactor programs validate supply-chain need without necessarily capturing fuel-cycle margins.
Relevance comes from scarce licensed capacity, qualified processes, customer offtake, transport approvals, material know-how, or evidence that the company controls a hard-to-substitute step in the chain.
