Health ImpactsPotential: Exposure to unknown or uncertain complex risks (radiation, etc…), Occupational disease and accidents, Other environmental related diseases, Accidents
OtherGori Nuclear plant near Busan, Koreass second city and also close to the city of Ulsan. In the case of a major accident the worst-case scenario simulation published in the press talks of up to 900 000 deaths. This is challenged.
Socio-economic ImpactsPotential: Displacement
Project StatusIn operation
Pathways for conflict outcome / responseUnder negotiation
Grass-roots activism and networking. Larger scale demonstrations. Lobbying parliamentarians
Development of AlternativesRenewables
Do you consider this as a success?Not Sure
Why? Explain briefly.This is ongoing and difficult to access final outcome. However, while under the former government of President Lee, nuclear power was supported in the framework of reducing carbon emissions. Since Fukushima, public opinion has turned against nuclear energy. By 2017, the new president has turned against nuclear power.
