Japan neglected carrying out safety checks on at least 40 percent of nuclear reactor parts exported over a decade, a report said yesterday, in the latest controversy to strike its troubled nuclear industry.
Nuclear reactor parts — including pressure vessels which contain the fuel in power plants — worth about ￥51.1 billion (US$520 million) were shipped to 17 countries, including Taiwan, without undergoing safety checks, the Mainichi Shimbun reported.
Britain, Germany, Australia, Russia and Italy were among the countries that took delivery of the potentially unsafe equipment, the daily said, citing manufacturers and an industrial body among its sources.
Japan exported nuclear reactor parts worth ￥124.8 billion to more than 20 countries from 2003 to last year, the Mainichi Shimbun said, citing official trade figures.
However, safety checks, entailing simple examinations of documents, were only required for exports tied to loans from the state-run Japan Bank for International Cooperation or guarantees by the public agency Nippon Export and Investment Insurance, the daily said.
The unchecked parts included reactor pressure vessels shipped to Taiwan in 2004 and control rod drives, which regulate the rate of nuclear fission, supplied to Sweden and Brazil, Mainichi said.
The rest of the exports are thought to have undergone government safety checks before being shipped to China, France, Belgium, Finland and the US, the daily said, citing the country’s Agency for Natural Resources and Energy.
However, much of the data disclosed by the agency was blacked out, raising the possibility that those exports may too have been shipped without being checked, Mainichi said.
Safety has been a huge concern for Japan’s nuclear industry since a massive earthquake and tsunami ravaged the country’s northeast coast and triggered a meltdown at the Fukushima Dai-ichi nuclear power plant in March 2011.
The country has continued overseas sales of nuclear reactor technology, with Japanese Prime Minister Shinzo Abe assuring buyers the industry is among the world’s safest.
COMPETITION: AMD, Intel and Qualcomm are unveiling new laptop and desktop parts in Las Vegas, arguing their technologies provide the best performance for AI workloads Advanced Micro Devices Inc (AMD), the second-biggest maker of computer processors, said its chips are to be used by Dell Technologies Inc for the first time in PCs sold to businesses. The chipmaker unveiled new processors it says would make AMD-based PCs the best at running artificial intelligence (AI) software. Dell has decided to use the chips in some of its computers aimed at business customers, AMD executives said at CES in Las Vegas on Monday. Dell’s embrace of AMD for corporate PCs — it already uses the chipmaker for consumer devices — is another blow for Intel Corp as the company
MediaTek Inc (聯發科) yesterday said it is teaming up with Nvidia Corp to develop a new chip for artificial intelligence (AI) supercomputers that uses architecture licensed from Arm Holdings PLC. The new product is targeting AI researchers, data scientists and students rather than the mass PC market, the company said. The announcement comes as MediaTek makes efforts to add AI capabilities to its Dimensity chips for smartphones and tablets, Genio family for the Internet of Things devices, Pentonic series of smart TVs, Kompanio line of Arm-based Chromebooks, along with the Dimensity auto platform for vehicles.

TECH PULL: Electronics heavyweights also attracted strong buying ahead of the CES, analysts said. Meanwhile, Asian markets were mixed amid Trump’s incoming presidency Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) shares yesterday closed at a new high in the wake of a rally among tech stocks on Wall Street on Friday, moving the TAIEX sharply higher by more than 600 points. TSMC, the most heavily weighted stock in the TAIEX, rose 4.65 percent to close at a new high of NT$1,125, boosting its market value to NT$29.17 trillion (US$888 billion) and contributing about 400 points to the TAIEX’s rise. The TAIEX ended up 639.41 points, or 2.79 percent, at 23,547.71. Turnover totaled NT$406.478 billion, Taiwan Stock Exchange data showed. The surge in TSMC follows a positive performance
ADVANCED: Previously, Taiwanese chip companies were restricted from building overseas fabs with technology less than two generations behind domestic factories Taiwan Semiconductor Manufacturing Co (TSMC, 台積電), a major chip supplier to Nvidia Corp, would no longer be restricted from investing in next-generation 2-nanometer chip production in the US, the Ministry of Economic Affairs said yesterday. However, the ministry added that the world’s biggest contract chipmaker would not be making any reckless decisions, given the weight of its up to US$30 billion investment. To safeguard Taiwan’s chip technology advantages, the government has barred local chipmakers from making chips using more advanced technologies at their overseas factories, in China particularly. Chipmakers were previously only allowed to produce chips using less advanced technologies, specifically
