Asia Nuclear Power Plants Growth

In Germany, tens of thousand environmentalists took to the street on March 12, 2011, the day after the quake struck in Japan, demanding the government to shift from atomic energy to clean energy. Yet, the threat Germany faces falls far behind Japan and Taiwan; the country is not located in the active earthquake zone, whereas its Asian counterparts are in the Pacific tectonic ‘ring of fire.’

Currently Japan has 17 nuclear power plants in its 378,000 square-kilometer territory and three more will be in operation by 2018. Taiwan covers an area of just 36,000 square kilometers, yet has three nuclear power plants and is building a fourth. The density of nuclear power plants is therefore much higher in Taiwan than in Japan, so you can image how Taiwanese feel when they see the disaster unfolding at Fukushima.

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:

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.

In spite of all the worries and questions raised by concerned citizens and experts, the Taiwanese government insists on having the fourth nuclear power plant in operation by 2011, as a celebration of the 100th anniversary of the founding of Republic of China.

In an exchange gathering between Japanese and Taiwanese green activists back in August 2010, some participants alerted [zh] that rushed nuclear construction might lead to future disaster:

In Taiwan, because of the order of the Executive Yuan [House of Administration], the construction of the fourth nuclear power plant is forced to be completed in 2011. This situation is similar to what happened in the Chernobyl disaster.

In 1983, there were three nuclear reactors working in the Chernobyl nuclear power plant, but the construction of the fourth reactor was delayed. The head of the plant did not dare to reveal the truth. At the same time, the Russian government hoped the construction of the fourth reactor could be completed before December 22 for the nuclear industry's annual memorial day. Therefore, the plant changed the original designs and materials. They managed to complete the construction on time. Later, they skipped a number of essential safety tests because they were hurrying to let the reactor start running for commercial purposes before March 27, 1984. The head of the plant and most managers there were honored and rewarded for meeting the deadline…In April 6, 1986, the newly built fourth reactor in the Chernobyl nuclear power plant exploded in a operational test.

In 2008, there was a scandal in the construction of the fourth nuclear power plant in Taiwan because the constructor changed the original design without authorization. Later, the control room was submerged in a typhoon. Recently, the plant has failed in a number of safety tests. Yet the constructors are hurrying to complete construction because of orders from the top. Is this a risk we want to take?

From a CNA report yesterday: “Amid calls for a temporary suspension of the fourth nuclear plant for an overall review, [Premier] Wu said that the plant has been rescheduled to begin operations in 2013, one year later than originally planned, to alleviate safety concerns.”

The Taipei Times today also mentions a delay, but doesn’t give a specific date: “[Premier] 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.
