In 2013, there was a scandal involving the use of counterfeit parts in nuclear plants and faked quality assurance certificates. In June 2013 Kori 2 and Shin Wolsong 1 were shut down, and Kori 1 and Shin Wolsong 2 ordered to remain offline, until safety-related control cabling with forged safety certificates is replaced. Control cabling in the first APR-1400s under construction had to be replaced delaying construction by up to a year. In October 2013 about 100 people were indicted for falsifying safety documents, including a former chief executive of Korea Hydro &amp; Nuclear Power and a vice-president of Korea Electric Power Corporation.
