On Tuesday, mistakes by CPC Corp, Taiwan personnel stopped gas supplies to the Datan Power Station in Taoyuan for two minutes, tripping all six generators at the plant. At the same time, generators were offline at Taiwan Power Co’s (Taipower, 台電) Taichung and Tongsiao power plants, as well as at Ho-Ping Power Co’s plant in Hualien County.
The result was that region after region across Taiwan experienced power outages.
Calls to restore nuclear power were immediately heard, but given the constant problems at power stations, how can anyone have confidence in nuclear power?
The Chernobyl and Three Mile Island nuclear disasters were because of human error.
In Taiwan, oversights during repairs at the Jinshan Nuclear Power Plant’s reactor No. 1 in July 2013 caused core cooling to exceed the reactor’s embrittlement alert value for more than an hour; in March last year, reactor No. 2 at the same plant was stopped for four days because a switch had been thrown by mistake.
In March 2003, crane cables at the Guosheng Nuclear Power Plant’s reactor No. 1 were connected the wrong way, causing fuel bundles to slip and fall; in November 2012, a circuit breaker of reactor No. 2 at the plant was cut by mistake, resulting in a reactor shutdown.
In April 1996, steam leaked at the Ma-anshan Nuclear Power Plant’s reactor No. 1 because a valve had not been closed; in May, reactor No. 2 at the plant tripped due to operational error.
In May 2010, equipment at the Fourth Nuclear Power Plant reactor No. 1 burned because the wrong equipment was used during cleaning, which caused an error in a control chip; and in July 2010, false firing caused the wrong signal to be sent, resulting in loss of external power for 28 hours.
Had the Longmen plant in New Taipei City’s Gongliao District (貢寮) been operational during the last of those incidents on the list, Taiwan would have experienced a nuclear disaster.
Problems at non-nuclear power stations mean temporary inconveniences; a nuclear disaster could mean life or death for a small nation like Taiwan.
Article 95 of the Electricity Act (電業法) states that “the nuclear-energy-based power-generating facilities shall wholly stop running by 2025.”
Continued demands that nuclear plants be kept online ignores the law, and even if the Fourth Nuclear Power Plant — which was plagued by problems during construction — was to become operational and fortune kept it free from accidents, making it operational would not be economically feasible, as it would have to be decommissioned in under eight years.
Tuesday’s power outage was not a matter of insufficient power facilities, it was an accident. Fortunately, it was not an accident at a nuclear plant.
Hopefully the government will stick to its guns and make Taiwan a nuclear-free nation.

US President Donald Trump has gotten off to a head-spinning start in his foreign policy. He has pressured Denmark to cede Greenland to the United States, threatened to take over the Panama Canal, urged Canada to become the 51st US state, unilaterally renamed the Gulf of Mexico to “the Gulf of America” and announced plans for the United States to annex and administer Gaza. He has imposed and then suspended 25 percent tariffs on Canada and Mexico for their roles in the flow of fentanyl into the United States, while at the same time increasing tariffs on China by 10
Trying to force a partnership between Taiwan Semiconductor Manufacturing Co (TSMC) and Intel Corp would be a wildly complex ordeal. Already, the reported request from the Trump administration for TSMC to take a controlling stake in Intel’s US factories is facing valid questions about feasibility from all sides. Washington would likely not support a foreign company operating Intel’s domestic factories, Reuters reported — just look at how that is going over in the steel sector. Meanwhile, many in Taiwan are concerned about the company being forced to transfer its bleeding-edge tech capabilities and give up its strategic advantage. This is especially
US President Donald Trump last week announced plans to impose reciprocal tariffs on eight countries. As Taiwan, a key hub for semiconductor manufacturing, is among them, the policy would significantly affect the country. In response, Minister of Economic Affairs J.W. Kuo (郭智輝) dispatched two officials to the US for negotiations, and Taiwan Semiconductor Manufacturing Co’s (TSMC) board of directors convened its first-ever meeting in the US. Those developments highlight how the US’ unstable trade policies are posing a growing threat to Taiwan. Can the US truly gain an advantage in chip manufacturing by reversing trade liberalization? Is it realistic to
Last week, 24 Republican representatives in the US Congress proposed a resolution calling for US President Donald Trump’s administration to abandon the US’ “one China” policy, calling it outdated, counterproductive and not reflective of reality, and to restore official diplomatic relations with Taiwan, enter bilateral free-trade agreement negotiations and support its entry into international organizations. That is an exciting and inspiring development. To help the US government and other nations further understand that Taiwan is not a part of China, that those “one China” policies are contrary to the fact that the two countries across the Taiwan Strait are independent and
