• Did cheap Megatons-to-Megawatts Russian LEU actually cause USEC's 2014 bankruptcy, or was the American Centrifuge project's own cost overruns the driver — and what does a primary source say?

• USEC's own 10-K attributes the American Centrifuge Plant's non-viability primarily to a global post-Fukushima LEU oversupply, not specifically to the Russian LEU USEC itself imported

• USEC's own 2013 Form 10-K states its Chapter 11 filing was to restructure its balance sheet and refinance $530 million in maturing convertible notes — not a response to Russian LEU competition

• The National Security Archive's 2014 EBB 491 posting restates Project Sapphire's ~600 kg U-235 figure in pounds, and relabels it as gross weapons-grade uranium — an editorial gloss on the document it publishes, not independent corroboration

• The cheap Russian LEU that USEC marketed under Megatons to Megawatts undercut its own American Centrifuge project and contributed to USEC's 2014 bankruptcy and rebrand as Centrus
