The anti-nuclear movement in South Korea consists of environmental groups, religious groups, unions, co-ops, and professional associations. In December 2011, protesters demonstrated in Seoul and other areas after the government announced it had picked sites for two new nuclear plants.^[1]

The "East Coast Solidarity for Anti-Nuke Group" was formed in South Korea in January 2012. It was created by the Justice and Peace committees of the four Catholic dioceses of Andong, Busan, Daegu and Wonju. The group is against nuclear power or nuclear weapons and in favour of peace. The group will ask the government to cancel its plans for new nuclear power plants in Samcheok and Yeongdeok. They will also demand the closure of existing nuclear reactors in Wolseong and Gori, and release of information about them.^[2]
