The earthquake that hit Japan on Friday last week has provided additional ammunition to environmental activists who are worried that one of Taiwan’s nuclear power plants lies within an area known for its underwater volcanoes.
Lee Chao-shing (李昭興), a professor of applied geosciences at National Taiwan Ocean University, said last year that as many as 70 underwater volcanoes are located within an 80km radius of the soon-to-be-operational Fourth Nuclear Power Plant in Gongliao District (貢寮), New Taipei City (新北市).
Up to 11 of those volcanoes are active, Lee said.
Although atomic regulatory officials dismissed the risks, activists said the authorities should take another look in light of the nuclear incidents in Japan.
The volcanoes, which have the highest concentration near a nuclear plant in the world, could lead to “a serious disaster” in the event of an earthquake or tsunami on the scale of that that struck Japan last week, Lee said.
The extent of their activity can be seen by the nearby presence of crabs, he said, pointing to video that showed hundreds of the crustaceans crawling at the base of what Lee said was an underwater volcano.
Democratic Progressive Party (DPP) legislators demanded that the government stop work on the Fourth Nuclear Power Plant — also known as the Longmen plant — which is expected to come online this year or next year.
DPP Legislator Tien Chiu-chin (田秋堇) said the government should adopt a more cautious approach given the research findings, suggesting it was time it “stopped, looked and listened carefully.”
“The findings support ... the view that a natural disaster off Taiwan would have even more serious consequences than [what is happening] at Fukushima,” she said, referring to fears of two nuclear meltdowns at the Fukushima Dai-ichi nuclear power plant in Japan.
Kao Cheng-yan (高成炎) of National Taiwan University, who is actively involved in the environmental movement, said the Longmen plant should not become operational.
“The reactors in the nuclear plant would be more unstable in the event of an earthquake. There are active volcanoes all around it,” he said.
Responding to the concerns, nuclear regulatory officials said the Fourth Nuclear Power Plant is safe, pointing to its location on stable bedrock and multiple backup systems, which officials say exceed those Japan had in place.
“We believe that [construction of] the fourth nuclear plant can continue as planned,” Taiwan Power Co chairman Edward Chen (陳貴明) said.
Taiwan is to commence mass production of the Tien Kung (天弓, “Sky Bow”) III, IV and V missiles by the second quarter of this year if the legislature approves the government’s NT$1.25 trillion (US$39.78 billion) special defense budget, an official said yesterday. Commenting on condition of anonymity, a defense official with knowledge of the matter said that the advanced systems are expected to provide crucial capabilities against ballistic and cruise missiles for the proposed “T-Dome,” an advanced, multi-layered air defense network. The Tien Kung III is an air defense missile with a maximum interception altitude of 35km. The Tien Kung IV and V
The disruption of 941 flights in and out of Taiwan due to China’s large-scale military exercises was no accident, but rather the result of a “quasi-blockade” used to simulate creating the air and sea routes needed for an amphibious landing, a military expert said. The disruptions occurred on Tuesday and lasted about 10 hours as China conducted live-fire drills in the Taiwan Strait. The Civil Aviation Administration (CAA) said the exercises affected 857 international flights and 84 domestic flights, affecting more than 100,000 travelers. Su Tzu-yun (蘇紫雲), a research fellow at the government-sponsored Institute for National Defense and Security Research, said the air
Taiwan lacks effective and cost-efficient armaments to intercept rockets, making the planned “T-Dome” interception system necessary, two experts said on Tuesday. The concerns were raised after China’s military fired two waves of rockets during live-fire drills around Taiwan on Tuesday, part of two-day exercises code-named “Justice Mission 2025.” The first wave involved 17 rockets launched at 9am from Pingtan in China’s Fujian Province, according to Lieutenant General Hsieh Jih-sheng (謝日升) of the Office of the Deputy Chief of the General Staff for Intelligence at the Ministry of National Defense. Those rockets landed 70 nautical miles (129.6km) northeast of Keelung without flying over Taiwan,
A strong continental cold air mass is to bring pollutants to Taiwan from tomorrow, the Ministry of Environment said today, as it issued an “orange” air quality alert for most of the country. All of Taiwan except for Hualien and Taitung counties is to be under an “orange” air quality alert tomorrow, indicating air quality that is unhealthy for sensitive groups. In China, areas from Shandong to Shanghai have been enveloped in haze since Saturday, the ministry said in a news release. Yesterday, hourly concentrations of PM2.5 in these areas ranged from 65 to 160 micrograms per cubic meter (mg/m³), and pollutants were
