Premier Wu Den-yih (吳敦義) responded to legislators’ concerns over nuclear safety yesterday by saying that nuclear power plants in Taiwan were “much safer” than Japan’s Fukushima Dai-ichi because they used “fourth-generation” reactors.
Telling legislators the government would “humbly” review its disaster plans and make any necessary improvements, Wu said he was confident the geological environment in Taiwan and the structure of its nuclear power plants meant that the country was well prepared to withstand any natural catastrophe.
Regarding the safety of the three nuclear power plants in operation — Jinshan Nuclear Power Plant in Shihmen District (石門), New Taipei City (新北市), Guosheng Nuclear Power Plant in Wanli (萬里), New Taipei City and Ma-anshan Nuclear Power Plant in Ma-anshan (馬鞍山), Pingtung County — Wu said all three were “much safer” than Fukushima Dai-ichi, which is the object of international concern following a series of explosions and a possible meltdown.
Asked by Chinese Nationalist Party (KMT) Legislator John Chiang (蔣孝嚴) whether the three nuclear plants were earthquake--resistant, Wu said: “That is difficult to say because even a country like Japan, which is more advanced than us, failed to avert disaster.”
“However, the Fukushima plant was equipped with a third--generation [reactor], while Taiwan’s nuclear power plants operate fourth-generation [sic] ones,” Wu said.
According to related literature, fourth-generation nuclear reactors are still being researched and will not be commercially operational for another two decades or so.
Contacted by the Taipei Times, Chung Ming-lien (鍾明廉), chief of public relations at Taipower Corp, which operates Taiwan’s nuclear plants, said there was no fourth--generation reactor in the country.
The Atomic Energy Council Web site shows the Jinshan power plant uses a BWR-4 (boiling water, second-generation) reactor; the Guosheng plant a BWR-6 (third-generation) reactor; the Ma-anshan plant a PWR (pressurized water, third-generation) reactor; and the No. 4 (Lungmen) will use an ABWR (advanced boiling water, also third-generation) reactor.
Units 2, 3, 4, and 5 at Fukushima Dai-ichi all have BWR-4 reactors similar to that at the Jinshan plant in Taiwan.
Wu also said the containment shells around reactors in Taiwan’s nuclear power plants were thicker than those used in Japan.
In addition, the three operational nuclear power plants in Taiwan were unlikely to be damaged by a tsunami because they were built at elevations of between 12m and 15m, Wu said.
Despite the fact that the No. 4 plant, which is currently under construction, is not located on elevated ground, the likelihood of a tsunami hitting it is also low because “Taiwan has only an outside chance of being hit by tsunamis,” the result of a deep-sea trench off the east coast, Wu said.
“The largest tsunami to ever hit Taiwan was a wave between 4m and 6m recorded in the Keelung area in 1867, while one in the 1900s caused a wave of less than 1m,” he said.
Wu also rallied behind Atomic Energy Council Deputy Minister Huang Tsing-tung (黃慶東), who came under criticism from anti-nuclear activists for drawing an analogy between nuclear power plants established on a consolidated-rock basin and a Buddhist sitting on a lotus platform on Monday to highlight their safety.
“Do you agree with Huang Tsing-tung? Are the nuclear power plants as safe as a Buddhist?” Democratic Progressive Party (DPP) Legislator Kuo Jung-tsung (郭榮宗) asked.
“This was not a groundless analogy,” Wu said.
Wu also said it would be “inappropriate” to fly the national flag at half-mast in sympathy with Japan, as no other country had done so.
“If everyone wears shorts to the swimming pool, but we chose to wear a suit, it would be extremely strange, wouldn’t it,” he said.
Taiwan would observe international protocol, which the Ministry of Foreign Affairs would look into, he said.
DPP Legislator Hsueh Ling (薛凌) said the country flew the national flag at half-mast following the Sept. 11, 2001, attacks in the US.
Meanwhile, DPP lawmakers demanded that Wu order the suspension of construction at the No. 4 plant, a move Wu rejected.
Wu said that the government would make a thorough safety inspection of the plant before it goes into operation, which will now not be the end of this year as planned.
KMT Legislator Lin Yu-fang (林郁方) said halting construction of the plant was “a stupid idea” as it would cost the country large amounts of money for breach of contract.
Rather than halting construction, the government should support and develop systems off the coast to monitor undersea seismic movements to provide warnings of earthquakes and tsunamis, Lin said.

Super Typhoon Kong-rey is the largest cyclone to impact Taiwan in 27 years, the Central Weather Administration (CWA) said today. Kong-rey’s radius of maximum wind (RMW) — the distance between the center of a cyclone and its band of strongest winds — has expanded to 320km, CWA forecaster Chang Chun-yao (張竣堯) said. The last time a typhoon of comparable strength with an RMW larger than 300km made landfall in Taiwan was Typhoon Herb in 1996, he said. Herb made landfall between Keelung and Suao (蘇澳) in Yilan County with an RMW of 350km, Chang said. The weather station in Alishan (阿里山) recorded 1.09m of
NO WORK, CLASS: President William Lai urged people in the eastern, southern and northern parts of the country to be on alert, with Typhoon Kong-rey approaching Typhoon Kong-rey is expected to make landfall on Taiwan’s east coast today, with work and classes canceled nationwide. Packing gusts of nearly 300kph, the storm yesterday intensified into a typhoon and was expected to gain even more strength before hitting Taitung County, the US Navy’s Joint Typhoon Warning Center said. The storm is forecast to cross Taiwan’s south, enter the Taiwan Strait and head toward China, the Central Weather Administration (CWA) said. The CWA labeled the storm a “strong typhoon,” the most powerful on its scale. Up to 1.2m of rainfall was expected in mountainous areas of eastern Taiwan and destructive winds are likely
The Central Weather Administration (CWA) yesterday at 5:30pm issued a sea warning for Typhoon Kong-rey as the storm drew closer to the east coast. As of 8pm yesterday, the storm was 670km southeast of Oluanpi (鵝鑾鼻) and traveling northwest at 12kph to 16kph. It was packing maximum sustained winds of 162kph and gusts of up to 198kph, the CWA said. A land warning might be issued this morning for the storm, which is expected to have the strongest impact on Taiwan from tonight to early Friday morning, the agency said. Orchid Island (Lanyu, 蘭嶼) and Green Island (綠島) canceled classes and work
KONG-REY: A woman was killed in a vehicle hit by a tree, while 205 people were injured as the storm moved across the nation and entered the Taiwan Strait Typhoon Kong-rey slammed into Taiwan yesterday as one of the biggest storms to hit the nation in decades, whipping up 10m waves, triggering floods and claiming at least one life. Kong-rey made landfall in Taitung County’s Chenggong Township (成功) at 1:40pm, the Central Weather Administration (CWA) said. The typhoon — the first in Taiwan’s history to make landfall after mid-October — was moving north-northwest at 21kph when it hit land, CWA data showed. The fast-moving storm was packing maximum sustained winds of 184kph, with gusts of up to 227kph, CWA data showed. It was the same strength as Typhoon Gaemi, which was the most
