Lungmen Nuclear Power Plant
nuclear power plant in Gungliao, New Taipei, Taiwan

The Lungmen Nuclear Power Plant (Chinese: 龍門核能發電廠; pinyin: Lóngmén Hénéng Fādiànchǎng), formerly known as Gongliao and commonly as the Fourth Nuclear Power Plant (Chinese: 核四; pinyin: Hésì; lit. 'Nuke 4'), is an unfinished nuclear power plant in New Taipei City, Taiwan. It consists of two ABWRs each of 1,300 MWe net. It is owned by Taiwan Power Company (Taipower).
It was intended to be the first of these advanced Generation III reactors built outside Japan. The preceding four reactors in Japan were completed in four to five years. However, Taipower did not award the contract to a single architect/engineering firm; instead, they split the procurement among multiple vendors, complicating project management and increasing costs. In 2000, the project was canceled due to political opposition when it was approximately 10–30% complete but restarted in February 2001.
A national referendum was proposed in 2014 to decide if construction of the plant should continue, but the referendum was rejected from the ballot for contradictory and confusing language. Taipower submitted a plan to mothball Unit 1, which was by then complete, and freeze construction of Unit 2, starting in 2015.

Why this record matters
The phrase “nuclear power plant in Gungliao, New Taipei, Taiwan” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 30, 2025. The linked authority identifier is Q707536. Authority coordinates are 25.038, 121.924. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2000, 2001, 2014 and 2015.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
