Now, a snowballing scandal in South Korea about bribery and faked safety tests for critical plant equipment has highlighted yet another similarity: experts say both countries’ nuclear programs suffer from a culture of collusion that has undermined their safety. Weeks of revelations about the close ties between South Korea’s nuclear power companies, their suppliers and testing companies have led the prime minister to liken the industry to a mafia.
The scandal started after an anonymous tip in April prompted an official investigation. Prosecutors have indicted some officials at a testing company on charges of faking safety tests on parts for the plants. Some officials at the state-financed company that designs nuclear power plants were also indicted on charges of taking bribes from testing company officials in return for accepting those substandard parts.
Worse yet, investigators discovered that the questionable components are installed in 14 of South Korea’s 23 nuclear power plants. The country has already shuttered three of those reactors temporarily because the questionable parts used there were important, and more closings could follow as investigators wade through more than 120,000 test certificates filed over the past decade to see if more may have been falsified.
In a further indication of the possible breadth of the problems, prosecutors recently raided the offices of 30 more suppliers suspected of also providing parts with faked quality certificates and said they would investigate other testing companies.
“What has been revealed so far may be the tip of an iceberg,” said Kune Y. Suh, a professor of nuclear engineering at Seoul National University.
With each new revelation, South Koreans — who, like the Japanese, had grown to believe their leaders’ soothing claims about nuclear safety — have become more jittery. Safety is the biggest concern, but the scandals have also caused economic worries. At a time of slowing growth, the government had loudly promoted its plans to become a major builder of nuclear power plants abroad.
The scandal, Professor Suh said, “makes it difficult to continue claiming to build reliable nuclear power plants cheaply.”
South Koreans say they are already suffering for the industry’s sins. The closing of the three reactors, in addition to another three offline for scheduled maintenance, has led the country’s leaders to order a nationwide energy-saving campaign in the middle of a particularly muggy summer. At university campuses, students have deserted the libraries for cooler Internet cafes, and major corporations have turned down air-conditioning.
President Park Geun-hye has kept off her own air-conditioning even when she hosted foreign guests, including Mark Zuckerberg, the chief executive of Facebook. And some entrepreneurs have capitalized on the troubles, selling “cool scarves” made of a special fabric that, after being dipped in water, keeps wearers cool for hours. But the modeling and creativity have not stopped the grousing, or alleviated anger at the industry.
Critics of South Korea’s nuclear industry say there were plenty of warning signs.
Last year, the government was forced to shut down two reactors temporarily after it learned that parts suppliers — some of whom were later convicted — had fabricated the safety-test certificates for more than 10,000 components over 10 years. But the government emphasized at the time that those parts were “nonessential” items and that the industry was otherwise sound.
As it turned out, the problems went much deeper.
The investigation that began this spring suggested that the oversight within the supply chain may also be more deeply compromised. A company that was supposed to test reactor parts skipped portions of the exams, doctored test data or even issued safety certificates for parts that failed its tests, according to government investigators. And this time the parts involved included more important items. Among the parts that failed the tests were cables used to send signals to activate emergency measures in an accident.
