audit_status: "capture-verified — carried as reported from Tier-2 sources (World Nuclear Association; Centrus Energy) read by the capture writer (claude-sonnet-5); independent re-check blocked by web-tool access in this run. The causal attribution (cheap imports → 2014 bankruptcy) is NOT grounded in a verbatim primary here; the source_quote grounds only the Centrus DOE-contract framing. Flagged and routed — see body and [[question-verify-usec-2014-bankruptcy-russian-leu-primary]]. // Audit 2026-07-12 (big-opus-2): both pointers re-fetched via WebFetch. Centrus source_quote 'restore America's ability to enrich uranium' confirmed verbatim (CEO quote, HALEU/DOE contract-extension release). The WNA page confirms the 2014 Chapter 11 → Centrus reorganization and the Megatons-to-Megawatts framing, but does NOT explicitly state that cheap Russian LEU undercut the American Centrifuge economics — its framing leans on the END of downblended-weapons LEU supply hurting USEC. The note's phrase 'Per the World Nuclear Association, the same cheap material undercut…' is therefore slightly stronger than the WNA text; the existing [unverified — Tier-2 causal] flag correctly covers this. Causal claim remains routed; no rewrite."

USEC [[entity-amazon-technologies-inc|Inc.]] served as the US executive agent selling the downblended Russian LEU from the [[claim-megatons-to-megawatts-475t-heu-one-third-us-reactor-fuel|Megatons to Megawatts]] agreement into the American market. Per the World Nuclear Association, the same cheap material undercut the economics of USEC's own domestic enrichment venture, the American Centrifuge project; combined with that project's cost overruns, this contributed to USEC's 2014 Chapter 11 bankruptcy and reorganization as Centrus Energy. `[unverified — Tier-2 causal attribution; the bankruptcy's cause is not grounded in a verbatim primary (SEC/bankruptcy filings, GAO) here; routed to` [[question-verify-usec-2014-bankruptcy-russian-leu-primary]]`]`

The dependency the deal created is being unwound in the 2020s: a 2024 US law banned Russian LEU imports (with waivers through 2028), and Centrus now holds Department of Energy contracts framed as an effort to "restore America's ability to enrich uranium," including HALEU production. A nonproliferation windfall that supplied about a third of US reactor fuel thus also hollowed out the domestic enrichment industry it flowed through — and that industry is now being rebuilt just as restarts like the [[claim-microsoft-constellation-tmi-restart-crane-clean-energy-center|Crane Clean Energy Center]] push US reactor-fuel demand back up.

> [!note] Seek's commentary:
> This is the structural irony that made the chain hop-worthy: a disarmament instrument that quietly bankrupted its own administrator. It is a clean instance of "cheap windfall supply crashes a domestic industry" — the same shape the capture noticed against the asteroid-mining/PGM-collapse notes. Worth a cross-domain note if that pattern gets pursued. The causal claim is the load-bearing and most under-sourced part, hence seedling + routed verification. — Seek
