Korea's first nuclear plant suspended after 40 years of operation. June. 10, 2017 07:30. by Gun-Huk Lee gun@donga.com.

Built as Korea's first nuclear power plant at Gijang County, Busan, Gori-1 came to a halt after completing its four decades of service, providing electricity since 1978. Gori-1 ended its chapter in the history of Korean nuclear power generation, being the first-ever nuclear powerhouse and the first of its kind to be out of service for good.

The Nuclear Safety and Security Commission (NSSC) opened its 70th meeting on Friday and announced that it has approved the permanent suspension of Gori-1, requested by the Korea Hydro and Nuclear Power (KHNP) last June. Under the recent approval, KHNP will stop operating the aged plant, and will cool nuclear fuels as of midnight on June 19. KHNP plans to dissemble the plant in earnest starting in 2022.

Gori-1 opened an era of commercial nuclear power generation in Korea on April 29, 1978. Meeting the rapidly increasing power demands amid economic growth, it has layed grounds for the nation to develop into an industrial state. While it reached its design life (30 years) in June 2007, the plant was resuscitated and was operated for an additional 10 years after undergoing full repair and consensus with residents.

Some view the first permanent suspension of a Korean nuclear plant as the first step towards denuclearization by the new administration. During his campaign, President Moon Jae-in pledged to immediately close down outdated nuclear plants and reduce nuclear power generation. Under the recent decision made by NSSC, experts view that the extension policy for the lifecycle of a nuclear plant will be set as "once for 10 years." KHNP will hold a ceremony to celebrate the permanent halt of Gori-1 on June 19.
