The Lungmen Nuclear Power Plant (Chinese: 龍門核能發電廠; pinyin: Lóngmén Hénéng Fādiànchǎng; literally: "Dragon Gate Nuclear Power Plant") (formerly Gongliao Nuclear Power Plant and Fourth Nuclear Power Plant, often abbreviated as: Chinese: 核四; pinyin: Hésì; literally: "Nuke 4"), located nearby Fulong Beach, Gongliao District, New Taipei City, is Taiwan's fourth nuclear power plant, consisting of two ABWRs each of 1,300 MWe net. It is owned by Taiwan Power Company (Taipower). This will be the first of these advanced Generation III reactors built outside of Japan.

The preceding four reactors in Japan were completed in four to five years. Taipower, however, did not award the contract as a turnkey plant, but hired General Electric to build the reactors, Mitsubishi Heavy Industries to supply the turbines and the generators, and other contractors for the rest,[3] making the project very difficult to manage. In addition, the project was canceled in 2000 by the Government when it was 10-30% complete,[4] only to restart the following year. All these have resulted in significant cost overruns, while in 2011 the Taiwan Atomic Energy Council (AEC) criticized Taipower's management of the project.[5] The construction has been delayed by legal, regulatory and political delays.[6] The proposed 2014 national referendum to decide the fate of the power plant[7] was rejected from the ballot for contradictory and confusing language, despite gathering more than 120,000 signatures.[8]


The Fourth Nuclear Power Plant was first proposed in 1978,[9] and Taipower selected the ABWR in 1996 after a competitive bidding process.[10] The reactor is designed by General Electric, but is supported by Hitachi, Shimizu Corporation, Toshiba, and other American, Taiwanese, and other Chinese and international companies.[11]


Construction of the plant began in 1999[12] and was expected to be completed in 2004.

The 921 earthquake in 1999 prompted three legislators to inspect construction progress; they cited rusty rebar and potential seawater seepage into the plant's foundation as potential issues.[13] President Chen Shui-bian was elected along with other Democratic Progressive Party (DPP) legislators in March 2000 on an anti-nuclear platform which included stopping plant construction.[9][14] DPP legislators called for a halt to the project in April 2000,[15] which led to the suspension of construction in October 2000 by Premier Chang Chun-hsiung.[4] Contractors were idle for several months[16] before construction resumed in February 2001.[14]

Taipower constructed a wharf in 2003 to accommodate delivery of heavy components, such as the reactor vessel. The wharf was beset with construction delays and may have contributed to local beach erosion, prompting further protests.[17][18] Each reactor vessel delivery was greeted with activist protests[19] and construction delays resulted in the vessels being stored longer than expected, with Unit 1's reactor vessel not installed until 2005.[20]

Design of the plant was carried out by Stone & Webster (S&W), but Taipower canceled its contract with S&W in 2007, leading to protracted litigation from 2007 to 2011.[21]

In 2010, aboriginal artifacts were found at the construction site, prompting calls to halt construction again.[22]

Taipower was fined by the AEC twice, in 2008 and 2011, for completing design changes without first obtaining approval from the plant's designer, General Electric.[23][24] Taipower later stated the changes were executed to stay on schedule, and approval was later obtained from GE for 97% of the changes.[25]

The temporary cancellation by the Government and other project management difficulties caused significant delays, pushing the price tag of the plant to more than US$7.5 billion in 2009.[10] As of 2014, the total price tag was close to US$10 billion, or NT$300 billion.[6][26]

In August 2014, the plant completed its safety tests required before operation can begin. 126 systems were tested including cooling, shutdown, containment, control and power generation. Minister of Economic Affairs Chang Chia-juch said, "Passing the rigorous review illustrates the high standards of care invested in the design and construction of the facility." The reactor will be closed until the status is decided by referendum. In the meantime, the reactor costs 1.3 billion NT Dollars a year to maintain in a mothballed state.[6]

Construction of Lungmen Nuclear Power Plant

2013 and 2014 Referendums

Environmental groups called for a national referendum in April 2011, following the Fukushima Daiichi nuclear disaster.[27] By obtaining the signatures of a certain percentage of registered voters, or by legislative action, a referendum may be referred to the national ballot for voter action. However, due to the politically sensitive nature of the Fourth Nuclear Plant issue, legislatively-referred and voter-referred referendums have failed to enter the national ballot.

Because of growing anti-nuclear public sentiment, in February 2013 the Kuomintang (KMT)-led government proposed that a referendum should be issued, which would allow the people of the country to decide the fate of the plant.[28] The proposed referendum was sponsored by 32 KMT lawmakers led by Lee Ching-hua[29] and asked "Do you agree that the construction of the Fourth Nuclear Power Plant should be halted and that it not become operational?"[30] Referendums must have good voter turnout (greater than 50% of registered voters must participate in the referendum vote), and a majority of participating voters must vote yes in order for the referendum to become binding, meaning that poor voter turnout would ensure referendum defeat (and in the case of the Lee referendum, continued construction).[31] The opposition DPP claimed that getting better than 50% voter turnout in a non-Presidential election year was too difficult, and barricaded the legislative chamber to prevent a vote to place the Lee referendum on the national ballot. This led to a scuffle when KMT legislators attempted to break through the barricade, and the Lee referendum was not voted on.[32] In the following legislative session, protesters called on the government to withdraw the Lee referendum,[33] and it was subsequently withdrawn.[34]

Annette Lu used the local referendum process to debate the plant's fate as early as 2012.[35] Her petition for a local referendum gathered 50,000 signatures by March 2013,[36] but the proposed referendum was rejected by the Executive Yuan Referendum Review Committee in May 2013, ruling the issue was of national importance, and could not be decided by local referendum.[37] She launched another local referendum in June 2013[38] in opposition to the KMT-authored Lee referendum. Meanwhile, Lu filed suit in 2014 in the Taipei High Administrative Court over the Executive Yuan's rejection of the earlier referendum.[39] The court's decision is expected in August 2014.[40]

A competing referendum was launched in 2012 by National Taiwan University professor Kao Cheng-yan, initially as a local referendum[41] and then a national one in July 2014, once sufficient signatures had been gathered.[42] The language of the Kao referendum was formulated to require positive action: "Do you agree to allow Taiwan Power Co to insert fuel rods into the Fourth Nuclear Power Plant in New Taipei City for a test run" so poor voter turnout would result in referendum defeat, and thus create binding opposition to starting the plant.[7]

In April 2014, the government decided to halt construction. The first reactor was sealed after the completion of safety checks, and construction of the second reactor was halted. A final decision on whether to proceed with construction would be subject to another referendum.[43] The ruling KMT stated the purpose of a new referendum was to have the people decide the plant's fate while weighing the consequences of not bringing a major power source on-line.[44]

The proposed Kao referendum was rejected by the Executive Yuan Referendum Review Committee in August 2014, citing the language as confusing and contradictory, since the reason given for the referendum is in opposition to nuclear power, while the referendum itself asks to start a nuclear reactor.[8] Undaunted, supporters of the Kao referendum vowed in October 2014 to initiate another referendum.[45]


Generation III nuclear reactors have a 72-hour capability of passive cooling to prevent damage to their core should the plant face a total blackout after an emergency shut down. If core overheating and meltdown became unavoidable, these reactors have core catchers that will trap the molten fuel and stop the nuclear reaction. Finally, a tight containment ensures that no evacuation zone is required around a Generation III nuclear power plant.

The ABWR was designed to a 0.3G earthquake acceleration standard with the Lungmen units seismic hardening increased to 0.4G.


Usually, every custom made power plant has low reliability in the first few years of its operation. Some parts prove unsuitable and need replacement and also modifications become necessary. ABWR was standardized to avoid these, but unavoidably the first units displayed low reliability (45% - 70%) with the experience gained promising to make future units much better. Interestingly, the first two units built, Kashiwazaki Kariwa 6[46] & 7[47] fared much better than the following two, Hamaoka 5[48] and Shika 2.[49]
