Anti-nuclear advocates yesterday took the Atomic Energy Council (AEC) to task for allegedly being in the dark for as long as 10 hours about an incident in the Jinshan Nuclear Power Plant’s second reactor yesterday, renewing worries about the safety of the nation’s accident-plagued nuclear facilities.
Low lube oil pressure caused a built-in lube oil pump in one of the reactor’s two recirculation pumps to trip at 4:18am, disengaging the coupling between the oil pump and a motor.
According to standard procedures at the power plant in New Taipei City’s (新北市) Shihmen District (石門)), technicians then inserted control rods, reduced the operating speed of the other recirculation pump and decreased the reactor’s power level to 250,000 kilowatts.
The reactor returned to normal operations at 1:19pm.
Asked to comment on the incident at 2pm yesterday, council spokesman and Vice Chairman Chou Yuan-ching (周源卿) said he was not aware of it.
About 30 minutes later, Chou came back with an explanation.
“Every reactor is equipped with two recirculation pumps that are each responsible for [controlling the flow of] 50 percent of the water through the core. The accident was caused by the malfunction of a lube oil pump within one of the second reactor’s recirculation pumps, causing the reactor’s capacity to decrease to about 40 percent of its normal level,” Chou said.
State-owned Taiwan Power Co (Taipower) reported the incident to the council’s Department of Nuclear Regulation immediately, Chou said.
“However, as the accident was not considered threatening to public safety, the department did not demand a shutdown or notify me,” Chou said.
Green Citizens’ Action Alliance director-general Lai Wei-chieh (賴偉傑) criticized the council’s stance, saying that given the level of public concern about nuclear safety, the council should not have listened only to Taipower’s side of the story.
“Given the First [Jinshan] Nuclear Power Plant’s relatively outdated facilities, any small problem could be a prelude to a bigger accident,” Lai said.
Green Consumers Foundation chairman Jay Fang (方儉) linked the incident to the meltdown at the Fukushima Dai-ichi nuclear power plant in Japan in 2011, saying the meltdown was caused by a loss of coolant in reactors after power outages [triggered by an earthquake and tsunami] prevented the recirculation pumps from sending water to the cores.
Taipower should have closed the second reactor for a comprehensive examination, rather than “forcing” it to resume operation, Fang said.
“The council is supposed to be on high alert for any reactor accidents, yet it was clueless about the incident 10 hours later. I think what should be decommissioned first is not the Jinshan plant, but the council,” Fang said.
EXPANSIONIST: China deploys an average of 40 to 50 warships and coast guard vessels daily in the South China Sea, despite pledges not to militarize the region, an official said China is attempting to expand its influence across the First Island Chain and increase pressure on Japan by sending coast guard vessels into waters off of Taiwan under the pretext of maritime negotiations with Japan and the Philippines, a national security official said yesterday. China’s recent actions in the waters east of Taiwan and Japan and the Philippines’ exclusive economic zones (EEZ) are attempts to establish dominance in First Island Chain waters, said the official who declined to be named, adding that this is “expansion disguised as law enforcement.” Framing China’s actions solely as a cross-strait issue is a serious misjudgment that
Through analyzing fossil evidence, a research team at National Taiwan University (NTU) discovered the largest endemic bird to have lived in Taiwan, naming it Pavo miejue, or extinct peafowl (滅絕孔雀). The Mikado pheasant, which is printed on the back of the NT$1,000 bank note, was previously believed to be the biggest endemic bird to Taiwan. The research team’s findings suggest that Pavo miejue lived during the Pleistocene epoch tens of thousands of years ago. It is the first endemic extinct bird species discovered and formally named in Taiwan. The study was coauthored by NTU Institute of Ecology and Evolutionary Biology professor Tsai Cheng-hsiu (蔡政修),
Taiwan Taoyuan International Airport is to suspend its automated Skytrain service connecting Terminal 1 and Terminal 2 starting on July 1 to facilitate connection works for the upcoming Terminal 3, the airport operator said today. Passengers and staff who need to travel between the two terminals after the suspension can instead use the Taoyuan MRT or the airport's 24-hour shuttle bus service, Taoyuan International Airport Corp said. The Taoyuan MRT Airport Line directly links the two terminals, while the shuttle buses are to operate around the clock, the company added. The Skytrain provides free transportation between the airport’s two terminals for travelers and
Taiwan ranked 42nd in terms of peacefulness among 163 countries, down five places from last year, according to this year’s Global Peace Index. With an overall score of 1.751, Taiwan dropped from 37th last year, the report published by the global Institute for Economics and Peace showed. The overall score measures a country’s level of peacefulness using 23 quantitative and qualitative indicators across three domains — ongoing domestic and international conflict, societal safety and security, and militarization. While Taiwan ranked 42nd worldwide, it was listed in ninth place among the 19 Asian-Pacific countries in the report, after New Zealand, Singapore, Japan, Malaysia,
