Taiwan Power Co (Taipower, 台電), the nation’s biggest electricity producer, said it had extinguished a fire at a spare transformer at its No. 3 nuclear plant and that the station’s two generating units were unaffected and operating normally.
The transformer, between 100m and 200m from the plant’s reactors, wasn’t in use when the accident occurred, Hsu Hwai-chiung (徐懷瓊), vice president of the state-run utility, said at a press conference yesterday.
“Our initial investigation indicates that it was probably caused by a fault in the transformer,” Hsu said.
The fire broke out at around 3:15pm after a sudden surge in pressure triggered an oil leak, Hsu said.
The fire was extinguished by 3:48pm without any radiation leaks or injuries, he said.
Taipower operates three nuclear power plants and is building another. Nuclear-fired stations accounted for 21 percent of the country’s electricity output in April, the company’s Web site said.
The No. 3 station is about 6km from the southern beachside Hengchun Township (恆春) and has two units, each with a capacity of 951 megawatts. It started commercial operation in 1983, Hsu said.
The latest fire was the third since the plant began commercial operation.
Taipower said that none of the incidents caused radiation leaks.
Taiwan Semiconductor Manufacturing Co (TSMC, 台積電), the world’s largest contract chipmaker, on Monday issued a statement about the balanced life environment it provides its employees, in response to a Fortune article at the weekend in which several former and current employees in the US were quoted complaining about the company’s “brutal” corporate culture. In the statement, TSMC said average work hours at the company have not exceeded 50 hours a week over the past two years with only a few exceptions, such as when the company introduces a new technology process or speeds up building a new plant. In such situations,
At a red-brick factory in the German port city of Hamburg, cocoa bean shells go in one end and out the other comes an amazing black powder with the potential to counter climate change. The substance, dubbed biochar, is produced by heating the cocoa husks in an oxygen-free room to 600°C. The process locks in greenhouse gases and the final product can be used as a fertilizer, or as an ingredient in the production of “green” concrete. While the biochar industry is still in its infancy, the technology offers a novel way to remove carbon from the Earth’s atmosphere, experts have said. Biochar could
Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) shares yesterday rallied 2 percent on the local stock market after Nvidia Corp said the contract chipmaker would be the sole supplier of its latest graphics processing chip, defusing speculation that Intel Corp would get a share of the orders. TSMC’s share price climbed to NT$562, snapping a three-day losing streak. It outperformed the benchmark index’s 1.18 percent gain. Net purchases by foreign institutional investors yesterday totaled 8.37 million shares, reversing net sales of 2.9 million shares on Thursday. The rebound follows Nvidia’s announcement that its latest artificial intelligence graphics processing unit (GPU), codenamed H100, would
WEAK PROSPECTS: The contract electronics manufacturer expects revenue to drop this quarter due to product transitions and a high comparison base a year earlier Hon Hai Precision Industry Co (鴻海精密), a major iPhone assembler, yesterday posted a second straight monthly growth in revenue to NT$45.07 billion (US$1.47 billion) last month, thanks to a pickup in smartphone demand. Last month’s revenue marked its best performance since January. On an annual basis, sales dipped 9.45 percent, the smallest annual decline since February, compared with NT$49.78 billion in May last year. Revenue from smart consumer electronics products, primarily iPhones and smartphones for other brands, delivered a “strong” double-digit, month-on-month growth in May because of customers’ pull-in, Hon Hai said in a company statement. That was the only business category
