Environmental activists wearing masks shout slogans during a rally demanding the government halt the building of more nuclear plants in South Korea, in Seoul March 28, 2011, on the 32nd anniversary of U.S. Three Mile Island nuclear power plant accident in 1979. South Korea, a major global supplier of nuclear plants, will carry on with its nuclear plans despite the crisis at a quake-hit nuclear complex in nearby Japan, a government minister said on Monday. Nuclear power accounts for 31.4 percent of South Korea's electricity generation needs, and the world's fifth-largest oil importer has a target to increase that to 48.5 percent by 2024. It has 7 reactors under construction, with plans to build 6 more and bring to 34 the number on-stream by 2024. REUTERS/Jo Yong-Hak (SOUTH KOREA - Tags: POLITICS CIVIL UNREST ENVIRONMENT ANNIVERSARY)
