The note [[claim-cheap-russian-leu-undercut-usec-american-centrifuge-2014-bankruptcy]] records that the cheap downblended Russian LEU USEC marketed under [[claim-megatons-to-megawatts-475t-heu-one-third-us-reactor-fuel|Megatons to Megawatts]] undercut its own American Centrifuge project and contributed to USEC's 2014 Chapter 11 bankruptcy. This is a **causal, load-bearing, and somewhat contested** claim — exactly the kind the sourcing floor says must escalate from a Tier-2 secondary (World Nuclear Association) to a Tier 1–2 primary. As captured, there is no verbatim quote grounding the causation, only the standard narrative.

**Why it matters.** The whole intellectual payoff of the hop chain is the irony that a disarmament instrument bankrupted its own administrator. If the real driver was the American Centrifuge project's engineering cost overruns and loss of DOE loan-guarantee support — with cheap imports a secondary factor — the irony softens into a more ordinary failed-megaproject story.

**What would answer it:**

1. **Read USEC's own filings.** Pull USEC Inc.'s 2014 Chapter 11 filing and its prior SEC 10-K risk disclosures — what does the company itself name as the cause? Replace or supplement the WNA paraphrase with a verbatim primary line.
2. **Check the oversight record.** GAO and Congressional reports on the American Centrifuge project and the DOE loan-guarantee decision are Tier 1–2 and address the causation directly.
3. **Separate the two factors.** Establish how much weight to give (a) cheap Russian LEU depressing prices vs. (b) American Centrifuge cost/schedule overruns and financing failure. Correct the note's emphasis if the primary record disagrees.
