According to the Board of Audit and Inspection (BAI), the Korea Hydro and Nuclear Power Co., the state-run operator of nuclear power plants, last year bought a total of 966 parts that had fabricated test results, to be used in two reactors at the Gori Nuclear Power Plant.
One supplier fabricated 83 different documents for 961 parts worth 10.95 billion won (US$10.13 million). The other five parts, worth 470 million won, provided by a different supplier, were accompanied by four forged documents and were constructed from unapproved material, the BAI said, announcing the results of an inspection conducted between April and June.
The revelations come one month after the government said a number of suppliers had been funneling "unproven" parts into the country's nuclear reactors by fabricating quality warranties.
In response the government said there was no threat of radiation leaks as the parts, including fuses and power switches, were unrelated to the reactor itself.
South Korea currently operates 23 nuclear reactors.
