Korea restarted the Gori-2 reactor Saturday, three years after the suspension for safety checks and facility improvement, the country's nuclear reactor operator said.

The nuclear reactor at the Gori Nuclear Power Plant, located in Busan, 325 kilometers southeast of Seoul, began commercial operations in April 1983 as the country's third nuclear reactor.

But its 40-year operational permission expired in April 2023, and its operations had been suspended for safety inspections and improvements that were required before the facility could resume power production.

The Korea Hydro & Nuclear Power Co., which operates the reactor, won permission last November to restart the nuclear reactor.
