The No. 1 reactor at the Guosheng Nuclear Power Plant in New Taipei City’s Wanli District (萬里) is to be shut down today after producing power for 40 years, Taiwan Power Co (Taipower, 台電) said yesterday.
The generator’s 40-year operating permit expires at the end of this year, but as the facility’s spent fuel storage is full, the 985 megawatt reactor would be shut down earlier in preparation for a major overhaul of the facility, the utility said.
Due to the shortage in storage space, Taipower reduced the plant’s power generation capacity by about 20 percent since late February.

The overhaul is expected to take six months and decommissioning of the No. 1 reactor would begin thereafter, Taipower said.
The plant’s second reactor is scheduled to operate until March 2023 when its operating permit expires, it said.
The administration of President Tsai Ing-wen (蔡英文) is committed to phasing out nuclear power generation by 2025 and replacing it with renewable sources of energy. It aims at an energy mix of 20 percent energy production from renewable sources, 50 percent from liquefied natural gas and 30 percent from coal.
Nuclear power accounted for about 11.2 percent of the nation’s energy production last year, down from a peak of 16 to 19 percent.
The Ministry of Economic Affairs said that other energy sources, including natural gas, and solar and hydro power, would in the short term make up for the energy produced by the No. 1 reactor at the Guosheng plant.
Taipower first proposed the reactor’s decommissioning three years ago, gaining approval from the Atomic Energy Commission in October last year.
The plan included the construction of a dry storage facility for used fuel.
However, the establishment of the facility might be delayed by a dispute between the New Taipei City Government and Taipower.
New Taipei City has yet to issue a permit for the storage of the reactor’s fuel rods, as it is opposed to a permanent spent fuel storage facility within its jurisdiction.
The London Metal Exchange (LME) discovered bags of stones instead of the nickel that underpinned a handful of its contracts at a warehouse in Rotterdam, the Netherlands, in a revelation that would deliver another blow to confidence in the embattled exchange. The amount of metal represents just 0.14 percent of live nickel inventories on the LME, worth about US$1.3 million at current prices, so the immediate effect on the metals markets is limited. However, the shock announcement has much wider implications. In an industry riddled with scandals, the LME’s contracts are viewed as unquestionably safe. The news that even a few of
Oil on Friday posted its worst weekly loss since the early months of the COVID-19 pandemic as banking turmoil poisoned investor sentiment. West Texas Intermediate for April delivery dropped 2.36 percent to US$66.74 per barrel, falling 12.96 percent for the week, the largest drop in almost three years. Brent crude for May delivery fell 2.32 percent to US$72.97, posting a weekly loss of 11.85 percent. The failure of Silicon Valley Bank and troubles at Credit Suisse Group AG drove investors from risk assets, with oil-options covering accelerating the sell-off. “Crude action this week reminded many of how quickly the commodity can be decimated by
US-based mobile chip designer Qualcomm Inc yesterday opened a manufacturing engineering and testing center in Hsinchu, expanding its presence in Taiwan. Qualcomm also expects to accelerate its purchases in Taiwan, which already rose to NT$240 billion (US$7.9 billion) last year, up from NT$90 billion five years earlier, and should hit NT$300 billion next year. The center is to provide services for the supply chain in the semiconductor industry, Roawen Chen (陳若文), senior vice president and chief supply chain and operations officer of Qualcomm, said at the facility’s inauguration ceremony. It is Qualcomm’s largest and most advanced engineering testing center outside of the company’s
Huawei Technologies Co (華為) has replaced more than 13,000 parts in its products that were hit by US trade sanctions, the Chinese tech giant’s founder said, according to a speech transcript from last month posted on Friday by a Chinese university. Ren Zhengfei (任正非) said Huawei had over the past three years replaced the 13,000 components with domestic Chinese substitutes, and had redesigned 4,000 circuit boards for its products, the transcript posted by Shanghai Jiao Tong University said. “As of now, our circuit board [production] has stabilized, because we have a supply of domestically produced components,” Ren said. He did not give details
