It was recently found out that at least 40 percent of nuclear reactor parts exported from Japan have failed to undergo safety inspections before getting shipped out of the country. Such practice has also been observed in the past ten years, affecting more than 17 countries, including Taiwan.
The nuclear reactor parts involved in this criticism-inviting negligence in the Japanese nuclear industry includes pressure vessels, which serve as container for fuel in power plants, considered to amount to about 51.1 billion yen (approx. US$520 million). Australia, Britain, Germany, Italy, and Russia are among the 17 countries that received the untested nuclear reactor parts from Japan. Based on official trade figures, more than 20 countries have purchased untested nuclear reactor parts worth 124.8 billion yen ($1.27 billion) from 2003-2012. Back in 2004, besides nuclear reactor pressure vessels shipped to Taiwan, control rod drives have also been untested before being shipped to Brazil and Sweden. These rod drives are used to regulate the rate of nuclear fission.
There were still nuclear parts that have gone through government safety inspections. According to the Agency for Natural Resources and Energy, those parts were exported to China, Belgium, Finland, France, and the United States. However, safety checks were only performed, with only the documents scrutinized, if an export nuclear part has been tied to the Nippon Export and Investment Insurance or loans from Japan Bank for International Cooperation.
