Tuesday, 10 Dec 2013 | 4:30 AM ET

SEOUL, Dec 10 (Reuters) - South Korea supplies about a third of its electricity from 23 nuclear power plants and plans to add 11 more by 2024, while the government is looking to lower its reliance on nuclear power to 29 percent of its total power supply by 2035. South Korea's energy ministry said on Tuesday it is considering decreasing its dependence on nuclear power to 29 percent, from a planned 41 percent by 2030. Of the current 23 units, five are offline as of Tuesday, and the total number of closure may rise as the country's nuclear reactor operator will go ahead with scheduled maintenance for another reactor, the Hanbit No. 5, on Thursday.
