Conversion, Enrichment, HALEU, And Fuel Fabrication
This page covers the fuel-cycle steps after mined uranium leaves the feedstock stage: conversion changes uranium concentrate into chemical forms that enrichers can process, enrichment raises the uranium-235 concentration into low-enriched uranium (LEU) or high-assay low-enriched uranium (HALEU), and fuel fabrication turns enriched material into pellets, rods, assemblies, or specialized reactor fuel. The node matters because existing reactors and advanced designs cannot turn nuclear demand into megawatt-hours without qualified fuel supply. The ranked read is LEU first for direct U.S. enrichment and HALEU capacity, CCJ second for scaled conversion and fuel-services economics, BWXT third for fuel-adjacent nuclear manufacturing, ASPI fourth as a speculative U.S. enrichment tail, and Silex/GLE as an off-grid watch row because local chart coverage is missing.
What the stack is: uranium conversion plants, enrichment cascades, HALEU production lines, deconversion services, licensed fuel-fabrication plants, quality systems, transportation packages, safeguards, and regulatory licenses that turn uranium feedstock into usable reactor fuel.
What it does: conversion prepares uranium for enrichment, enrichment adds separative work units (SWU) to raise uranium-235 concentration, HALEU supplies higher-assay fuel for many advanced reactor designs, and fabrication packages the material into fuel forms accepted by reactor operators.
Main physical and operating pieces: uranium hexafluoride (UF6) conversion, enrichment centrifuges or laser-enrichment systems, HALEU cylinders, deconversion lines, fuel pellets and bundles, TRISO or other advanced fuel forms, licensing files, safeguards, criticality controls, and customer qualification programs.
Where it sits: this stack sits between mined uranium feedstock and reactor operations, at licensed fuel-cycle facilities, manufacturing shops, customer fuel-procurement programs, and DOE-backed domestic supply projects.
How the parent theme uses it: nuclear power needs secure, qualified fuel before existing fleets, restarts, uprates, or advanced reactors can produce firm power; policy awards and utility demand become investable only when capacity funding, contracts, delivery milestones, margin, and cash conversion appear.
Terms used later: LEU is low-enriched uranium below 20% uranium-235; HALEU is LEU enriched between 5% and below 20%; SWU measures enrichment work; conversion turns uranium into processable chemical form; fuel fabrication makes reactor-ready fuel; backlog conversion means signed work becomes recognized revenue, margin, and cash.
Report boundary: this node is a tactical report layer. Durable company research stays in the linked knowledge pages. Price and volume context comes from read-only discovery daily_ohlc through 2026-06-12. SILXY / SLX.AX has no local discovery coverage in this checkout, so no API chart is attached to that watch row.
Current Setup
Fuel-cycle bottleneckPolicy support only matters when fuel capacity becomes contracts and cash.
Conversion, enrichment, HALEU, and fabrication are licensed industrial steps. The node pays when SWU, conversion, fuel, or DOE work becomes funded capacity, delivered product, segment margin, backlog conversion, and operating cash flow.
Positive proofLEU has the cleanest public HALEU and U.S. enrichment route.
CCJ adds real conversion and fuel-services revenue; BWXT adds nuclear manufacturing and fuel-adjacent fabrication.
Conversion gateFunding and delivery decide whether awards become economics.
Watch DOE task-order terms, utility supply contracts, licensing, construction, segment margin, capex, and cash burn.
Primary constraintCapacity timelines are long and source coverage is uneven.
ASPI and Silex/GLE remain tails until technology, licensing, offtake, funding, and delivery proof improves.
Feedstock inputU3O8 and UF6 supply
Industrial workConversion, SWU, HALEU
Customer proofDOE and utility contracts
Equity proofMargin, cash, backlog
Uranium feedstock cannot serve existing reactors or advanced reactor designs until conversion, enrichment, HALEU supply where needed, and fuel fabrication clear. The measured proof is signed SWU, conversion, HALEU, or fuel-fabrication work; capacity funding; licensing progress; delivery milestones; segment margin; backlog conversion; and operating cash flow. DOE states that many advanced reactor designs require HALEU, while EIA data still shows heavy foreign-origin SWU dependence in the U.S. reactor fuel chain.
The policy and contract setup is concrete enough to rank public equities. DOE's January 2026 awards gave American Centrifuge Operating / Centrus a $900 million HALEU enrichment task order, General Matter a separate $900 million HALEU task order, Orano Federal Services $900 million for LEU enrichment, and Global Laser Enrichment up to $28.5 million for next-generation enrichment technology. Public Law 118-62 restricts Russian LEU imports, with limited waivers ending by January 1, 2028. LEU has the cleanest public exposure, CCJ has operating conversion and fuel-services revenue, and BWXT adds funded nuclear manufacturing and fuel-adjacent fabrication capacity.
Awards and shortage signals still require delivered economics. LEU must fund a large capacity program while managing cash burn and Russian supply transition. CCJ is more diversified than this node and faces Port Hope relicensing into February 2027. BWXT has strong nuclear manufacturing evidence, but enrichment and HALEU are less direct to its earnings stream. ASPI and Silex/GLE are useful tails, yet they need licensing, technology validation, funding, offtake, and delivery proof before they can outrank revenue and backlog names.
Static setup labels and thresholds were built from weekly bars aggregated from discovery daily_ohlc through 2026-06-12. Selected-security right-rail charts call the report API with as_of=latest; refresh setup levels before using static thresholds as current trading evidence. Fundamental claims route to the LEU, CCJ, and BWXT security lanes, the parent nuclear-power map, official DOE/NRC/EIA sources, and company releases listed below.
Basket
The basket is inherited from the parent nuclear-power map and hand-curated with linked knowledge coverage, official company releases, SEC companyfacts, and read-only discovery checks. Ranking uses direct node economics and source-backed exposure first, funding and contract proof second, and technical timing last. ASPI stays chartable but speculative; Silex/GLE stays an off-grid watch row because the business fit is direct but this checkout has no maintained local OHLC route.
Direct U.S. enrichment and HALEU route where policy scarcity can become SWU sales, DOE work, backlog, and capacity funding.
Market cap$3.2B
Next earningsAug 4, 2026 est.
Latest qtr revenue$76.7M
Role in stack
Centrus sells SWU, uranium, and enriched uranium product to utilities and houses DOE-backed HALEU engineering and manufacturing work in Technical Solutions. Theme pressure becomes economics through LEU deliveries, HALEU task orders, partner contracts, capacity funding, and commercial-scale enrichment execution.
Revenue mix
Q1 2026 revenue was $44.6M from LEU and $32.1M from Technical Solutions. The LEU segment produced most gross profit, while Technical Solutions carries the HALEU and domestic-capacity buildout path.
Latest qtr revenue
Q1 2026 total revenue was $76.7M for the three months ended March 31, 2026, per Centrus's May 5, 2026 release. Revenue quality still depends on DOE task-order finalization, Russian supply access, 2026 capex, and cash-burn control.
Scaled fuel-cycle platform with current uranium, conversion, fuel-services, Westinghouse, and GLE exposure.
Market cap$44.0B
Next earningsJul 30, 2026 est.
Latest qtr revenueC$845M
Role in stack
Cameco owns uranium production, Blind River refining, Port Hope conversion, fuel-services capacity, Westinghouse exposure, and a 49% GLE stake. The node converts through realized uranium prices, UF6/UO2 conversion, fuel-services volume, Westinghouse cash value, and GLE licensing progress.
Revenue mix
Q1 2026 revenue was led by uranium at C$712M and fuel services at C$134M. Fuel services produced 3.3M kgU, sold 2.8M kgU, and generated C$54M of adjusted EBITDA.
Latest qtr revenue
Q1 2026 consolidated revenue was C$845M for the three months ended March 31, 2026, per Cameco's Q1 2026 release. The node-specific caveat is that uranium and Westinghouse dominate valuation while conversion and fuel services are only one part of the platform.
Nuclear manufacturing and fuel-adjacent fabrication route with stronger backlog proof than direct HALEU exposure.

Latest qtr revenue$860.2M
Role in stack
BWXT supplies naval reactors, special materials, advanced reactor work, commercial nuclear components, fuel handling, services, and fuel-adjacent manufacturing. Theme pressure becomes economics through funded orders, backlog conversion, Commercial Operations margin, PCG capacity, and customer-backed fuel or fabrication programs.
Revenue mix
Q1 2026 revenue split between Government Operations at $577.9M and Commercial Operations at $283.6M. Government nuclear work anchors the company, while Commercial Operations carries more of the commercial fuel, components, and services optionality.
Latest qtr revenue
Q1 2026 revenue was $860.2M for the three months ended March 31, 2026, per BWXT's May 4, 2026 release. The node-specific caveat is that enrichment and HALEU are less direct to BWXT than backlog, naval awards, commercial nuclear manufacturing, and margin conversion.
ASPIASP Isotopes
Speculative U.S. isotope and enrichment tail through Quantum Leap Energy, planned LEU/HALEU work, and regulatory milestones.
Market cap$0.8B
Next earningsNot confirmed
Latest qtr revenue$4.18M
Role in stack
ASP Isotopes and Quantum Leap Energy are trying to move from isotope separation and project announcements into U.S. conversion, enrichment, HALEU, LEU+, and deconversion capacity. The gate is official licensing, technology proof, customer offtake, funded construction, and disclosed unit economics.
Revenue mix
The current public filing mix is not a mature fuel-cycle revenue base. SEC companyfacts show Q1 2026 revenue of $4.18M, while the fuel-cycle thesis still depends on future QLE projects rather than current commercial enrichment revenue.
Latest qtr revenue
SEC companyfacts for ASPI show Q1 2026 revenue of $4.18M for the three months ended March 31, 2026, filed May 20, 2026. Nasdaq/Zacks did not provide an upcoming earnings date in the June 13, 2026 check.

Discovery And Chart Provenance
Read-only discovery checks used python -m discovery.cli status for LEU, CCJ, BWXT, and ASPI plus read-only DuckDB queries against daily_ohlc and instruments. Local daily bars cover LEU, CCJ, BWXT, and ASPI through 2026-06-12; SILXY / SLX.AX has no local daily_ohlc rows.
Weekly OHLC for selected-security charts is derived from daily rows by calendar week: first open, maximum high, minimum low, final close, and summed volume. Chart packages use a three-year visible horizon, 20-week EMA, 100-week EMA where enough history exists, and weekly volume.
Static setup labels retained from the prior node build: LEU below key trend; CCJ base forming; BWXT base forming; ASPI speculative tail above moving averages; Silex/GLE off-grid watch. The selected-security right rail uses /api/securities/{ticker}/chart?frequency=weekly&window=3y&as_of=latest.
Representative API validation was attempted against http://127.0.0.1:8765/api/securities/LEU/chart?frequency=weekly&window=3y&as_of=latest. During review, python -m api.run started uvicorn on 127.0.0.1:8765, but sandboxed loopback HTTP requests were blocked or could not connect. Static API attributes, chart triggers, route metadata, and absence of embedded OHLC payloads were verified; live HTTP chart rendering remains unverified.
