APR-1400
The APR-1400 is a Generation III pressurised water reactor from Korea Hydro & Nuclear Power. 8 units are operating and 4 are under construction, out of 21 on record.
South Korea's evolutionary PWR, developed from the OPR-1000 lineage which itself descends from Combustion Engineering's System 80+. Four units operate at Barakah in the United Arab Emirates, delivered close to schedule and budget, the strongest recent counterexample to the Western build record. It holds both US NRC design certification and European Utility Requirements certification.
