Notes

CA01 module (1,167 t) set 2026-08-29 per CINIE — single source, not asserted. construction start definitional note: excavation Dec 2024, FCD Dec 2025 per WNA/SNERDI (PRIS uses FCD); populated 2024 value frozen pending PRIS-direct review. Net capacity 1161 MWe per the WNA reactor database (1161 net / 1250 gross, data credited to IAEA PRIS), the one source listing both Bailong units, so both carry the same figure (set 2026-10-13); IAEA PRIS's own page showed 1160 net / 1254 gross (3400 MWt; PRIS id 2169) on 2026-10-12. The 1.25 GW per-unit figure in press reports is gross. The 1.25 GW per-unit figure in press reports is gross. PRIS (checked 2026-10-12) also gives construction start 2025-12-22 and construction licence 2024-09-27.
