Notes
Turkey's first NPP; Rosatom build-own-operate model. Dummy fuel loading completed June 2026 (NucNet, WNN, Anadolu Agency, NDK-supervised); as of 2026-09-15 real fuel NOT yet loaded — target end-Sep/early-Oct 2026, with first electricity possible late Dec 2026 and commercial operation ~8-10 months after fuel loading (i.e., 2026-2027 range). Rosatom CEO: fuel loading and unit 'lift-up' scheduled for fall 2026; Turkish minister aims for first electricity by end of 2026.
