Nuclear Power Plants in Taiwan

Taiwan will still have enough electricity even if it shuts down all 3 nuclear power plants.     # 4 nuclear power plant is under construction regardless Fukushima's lessons.


Government seeking to reduce nuclear reliance without sincerity

.......Abandoning nuclear power requires careful deliberation, said Hsu Sheng-hsiung, chairman of the Chinese National Federation of Industries, one of the meeting participants.

The high cost of a nuclear-free society will not only influence business operations but also individuals, he added........  (W T F???) 



High Risk
Indeed, the risk of nuclear power plants hit by an earthquake in Taiwan is very high, as 朱淑娟 (Shu-Chuan Chu) points out:
The first and second nuclear power plants are five to seven kilometers [km] away from the Shanjiao Fault in the Kinshan coastal area. The fourth nuclear power plant is less than five km away from six inactive faults. In addition, within a radius of 80 km of the fourth nuclear power plant, there are more than 70 undersea volcanoes, 11 of them are active.

[In Taiwan] The anti-earthquake design is 0.3g [g = measure of peak ground acceleration] for the first nuclear power plant and 0.4g for the second, third, and fourth plants. They are far weaker than the anti-earthquake design in Japan, which is [typically] 0.6g. Due to its strong earthquakes, Japan plans to have 1.0g anti-earthquake design for new nuclear power plants. Nevertheless, not many people in Taiwan care about the earthquake threat.
Because of the geographical similarities, 菊地洋一 (Yoichi Kikuchi), a Japanese expert in nuclear power plants, warns that nuclear power plants in Taiwan may have similar structure-related problems as those observed in Japan:
台灣核電廠全停掉電都夠用 圖片來源:黃明堂. 
台灣的核一、核二廠所用的反應爐與日本都是屬於同一型,而且兩國都是多地震國家,所以在日本發生的問題,台灣不可能會沒有 問題。最近的 BWR 型屬使用最高品質的 SUS316L 製造 (材料的質地較軟,因此較不容易產生裂痕的現象) ;各電力公司一再強調,這種材料絕對不會發生裂痕問題。可是實際上它還是發生了,這次日本東京電力公司隱瞞事件(註: 2002年)中也發現,其它的部分同樣也有裂痕。
The nuclear reactors in the first and second nuclear power plants in Taiwan are similar to many nuclear reactors in Japan. Since there are frequent earthquakes in Taiwan and Japan, what has happened in Japan will also happen in Taiwan. The recent design of the Boiling Water Reactor (BWR) has adopted high-quality SUS317L stainless steel as the construction material, which is softer and has fewer cracking problems, and all the nuclear power companies have kept stressing that this material will never develop cracks. In the current accident [Fukushima], we have seen the cracks. In fact, far back in 2002, cracks were found in the BWR in the investigation of the Tokyo electric power company scandal.
To summarize, the nuclear power plants in Taiwan are not immune to the natural forces that destroyed the Fukushima nuclear power plant.

Cracks of up to 30cm have been found on the core shroud of the No.1 reactor at the idled Guosheng Nuclear Power Plant in Wanli District (萬里), New Taipei City (新北市), an Atomic Energy Council official has confirmed.

Civic groups yesterday warned against reactivating the plant.

In addition to unsettled concerns about cracked anchor bolts at the reactor, Green Consumers Foundation chairman Jay Fang (方儉) revealed that two cracks were found on welded parts of the core shroud, which Fang said could lead to disaster if the reactor is reactivated without repairs.

Deputy Director of the Atomic Energy Council’s (AEC) Department of Nuclear Regulation Chen Yi-pin (陳宜彬) was quoted by the Chinese-language Liberty Times (the Taipei Times’ sister newspaper) yesterday as having confirmed on Sunday that the two long cracks were discovered during routine checkup and maintenance in March.

The core shroud is a large cylinder of circumferentially welded plates made of stainless steel, surrounding the reactor fuel core, which is composed of fuel rods assembled into bundles.

Nuclear power plants in Taiwan (view)

Green pog.svg Under construction plants
Taiwan currently has 4884 MWe of nuclear power capacity by means of 3 active plants and 6 reactors, which makes up around 8.1% of its national energy consumption. The technology chosen for the reactors has been General Electric BWR technology for 2 plants and Westinghouse PWR technology for the Maanshan Nuclear Power Plant. The Lungmen Nuclear Power Plant is currently under construction, but has encountered public opposition and a host of delays.

Active seismic faults run across the island, and some environmentalists argue Taiwan is unsuited for nuclear plants. A 2011 Natural Resources Defense Council report that evaluated the seismic hazard to reactors worldwide, as determined by the Global Seismic Hazard Assessment Program data, placed all of Taiwan's reactors within the highest risk group of 12 reactors within very high seismic hazard areas, along with some of Japan's reactors.

The Lanyu nuclear waste storage facility was built on Orchid Island (Lanyu) in 1982. The plant receives nuclear waste from Taiwan's three nuclear power plants operated by state utility Taiwan Power Company (Taipower). About 100,000 barrels of nuclear waste from the nation’s three operational nuclear power plants have been stored at the Lanyu complex.[3] In 2002 and 2012, there were major protests from local residents, calling on Taipower to remove the nuclear waste from the island.


All plants are run by Taipower. The Atomic Energy Council (AEC) of the Republic of China is effectively the regulatory body, but plants are also subject to International Atomic Energy Agency safeguards. There are two additional plants under construction equipped with GE latest BWR technology in Lungmen. They will each deliver 1300 MWe of power at peak.

Nuclear waste controversy

Nuclear Waste Deposit site in Orchid Island.
The Lanyu nuclear waste storage facility was built on Orchid Island (Lanyu) in 1982. The storage plant is at the southern tip of the 45-square-kilometer island, which is located off the southeastern coast of Taiwan proper. The plant receives nuclear waste from Taiwan's three nuclear power plants operated by state utility Taiwan Power Company (Taipower). Islanders did not have a say in the decision to locate the facility on the island.

In 2002, almost 2,000 protesters, including many Aboriginal residents of Taiwan's Orchid Island staged a sit-in in front of the storage plant, calling on Taipower to remove nuclear waste from the island.

They were also protesting against the government's failure to keep its pledge to withdraw 100,000 barrels of low-level nuclear waste from their isle by the end of 2002. In a bid to allay safety concerns, Taipower has pledged to repackage the waste since many of the iron barrels used for storage have become rusty from the island's salty and humid air. Taipower has for years been exploring ways to ship the nuclear waste overseas for final storage, but plans to store the waste in an abandoned North Korean coal mine have met with strong protests from neighboring
South Korea and Japan due to safety and environmental concerns, while storage in Russia or China is complicated by political factors. Taipower is "trying to convince the islanders to extend the storage arrangement for another nine years in exchange for payment of NT$200 million (about $5.7 million)".

About 100,000 barrels of nuclear waste from the nation’s three operational nuclear power plants have been stored at the Lanyu complex. A report released in November 2011 said a radioactive leak had been detected outside the facility and this has added to residents’ concerns. In February 2012, hundreds of Tao Aborigines living on Lanyu held a protest outside the Lanyu nuclear waste storage facility, calling on Taiwan Power Co. to remove nuclear waste from the island as soon as possible. Tao People Protest Against Nuclear Waste

Following the Fukushima I nuclear accidents in Japan, nuclear energy has emerged as a contentious issue. In March 2011, around 2,000 anti-nuclear protesters demonstrated in Taiwan for an immediate halt to the construction of the island's fourth nuclear power plant. The protesters were also opposed to plans to extend the lifespan of three existing nuclear plants.

On the eve of World Environment Day in June 2011, environmental groups demonstrated against Taiwan's nuclear power policy. The Taiwan Environmental Protection Union, together with 13 environmental groups and legislators, gathered in Taipei with banners that read: "I love Taiwan, not nuclear disasters". They protested against the nation’s three operating nuclear power plants and the construction of a fourth plant. They also called for "all nuclear power plants to be thoroughly re-evaluated and shut down immediately if they fail to pass safety inspections".

According to Wang To-far, economics professor at National Taipei University, "if a level-seven nuclear crisis were to happen in Taiwan, it would destroy the nation". George Hsu, a professor of applied economics at National Chung Hsing University in central Taiwan, said nuclear power plants in quake-prone areas need to be redesigned to make them more resistant, an investment that would reduce their original cost advantage.

The retirement of existing nuclear reactors was a significant issue in the 2012 presidential election.

Taiwan's nuclear nightmare?

A fourth nuclear plant got the go-ahead, but activists say a disaster worse than Fukushima is on the horizon.

TAIPEI, Taiwan — In the year since Japan's Fukushima disaster, much of the world has turned away from nuclear power. Germany has plans to close down all of its nuclear plants by 2022, and Japan has already shut down all 54 reactors.

But Taiwan is not following suit. Despite campaign promises to move Taiwan away from nuclear power, the newly re-elected President Ma Ying-jou has vowed to go forward with the opening of a contentious fourth nuclear power plant.

Taiwanese anti-nuclear activists are crying foul, saying that more than feeling betrayed by Ma, they believe the Longmen plant is simply not safe. It puts the general population at great risk, they say, and could lead to further nuclear investments on this earthquake- and tsunami-prone island.

In the run up to January’s presidential poll, and in the wake of Fukushima, Ma said all the right things to an electorate that had grown disenchanted with the benefits of cheap nuclear power for a resource-strapped country that imports 99 percent of its energy needs. (Keep reading......

About 7 million people could die as a result of a nuclear disaster at the plant
the plant ‘s safety has been constantly questioned by domestic nuclear experts…  Like Japan, Taiwan is also prone to  massive earthquakes.....

 The View from Taiwan: Nuclear Round Up

 Nuclear Power Emerges as Election Issue

Although the presidential race has mostly been about pocketbook concerns and, to a lesser extent, Taiwan’s relationship with China, the leading challenger has made the elimination of Taiwan’s reliance on nuclear energy a central plank of her campaign. Pollsters and analysts say that the challenger, Tsai Ing-wen of the Democratic Progressive Party, has a good chance of unseating the incumbent, Ma Ying-jeou, whose party has long been a reliable backer of nuclear energy. 
  • Taiwan has six nuclear power reactors operating, and two advanced reactors are under construction. 
  • Nuclear power is considerably cheaper than alternatives.  (( Lies plus ignorance))


 Nuclear Power in Taiwan

Taiwan imports 99% of its energy, which is vital to the rapidly industrialising economy.
Electricity demand was growing at almost 5% per year, but this is slowing to about 3.3% pa to 2013.  Nuclear power has been a significant part of the electricity supply for two decades and now provides one quarter of base-load power and 17% overall, though nuclear comprises only 11% of 46 GWe installed capacity.  Coal-fired plants comprise 26% of capacity and in 2008 delivered 38% of the power.  LNG provides 20% of the power.  Total power generated in 2008 was 238 billion kWh, nuclear being 17% of this, 40.8 billion kWh gross, 39.3 TWh net. 

The three nuclear plants comprise four General Electric boiling water reactors and two Westinghouse pressurised water reactors.  Construction of the first unit began in 1972.  They are all operated by the utility Taipower, under the Ministry of Economic Affairs and were expected to have 40-year lifetimes.  Five of the six units had undergone minor uprates by the end of 2008, resulting in net 44 MWe increase.
