[ISN] S. Korea nuclear hack ups aging reactor risks

http://www.japantimes.co.jp/news/2015/01/13/asia-pacific/s-korea-nuclear-hack-ups-aging-reactor-risks/ Reuters Jan 13, 2015 SEOUL – The hacking of South Korea’s nuclear operator means the country’s second-oldest reactor may be shut permanently due to safety concerns, said several nuclear watchdog commissioners, raising the risk that other aging reactors may also be closed. “The operator failed to prevent it (the hack) and they don’t know how much data has been leaked. If the old reactor is still allowed to continue to run, it will just hike risks,” said Kim Hye-jung, one of nine commissioners who will this month review an application to restart the Wolsong No. 1 reactor. The future of Wolsong No. 1, shut in 2012 after reaching its 30-year life span, is seen as critical to the fate of other reactors, including the oldest, Kori No. 1, which had its life span extended by 10 years to 2017. Nuclear power accounts for about a third of South Korea’s electricity supply. More nuclear closures would boost fuel imports, which had soared since late 2012 after some reactor closures forced Asia’s fourth-largest economy to replace nuclear power with liquefied natural gas and thermal coal.
