Summary
Evidence
Open evidence ledger →| ID | Date | Category | Source | Confidence | Status | Notes |
|---|---|---|---|---|---|---|
| EV-034 | 2026-03-26 | Technical | Technical literature | Medium | Under Review | A domestic purification line has not been operated at commercial scale by any U.S. producer; the closest precedent is a 2023 pilot facility in North Carolina operating at approximately 1/20th of the throughput this program would require. |
| EV-035 | 2026-03-27 | Technical | Technical literature | Medium | Verified | Preliminary engineering estimates place capital cost for a domestic purification line at $85–110 million, with a wide range reflecting the absence of a directly comparable built precedent. |
