Genkai Nuclear Power Plant
nuclear power plant
The Genkai Nuclear Power Plant (玄海原子力発電所, Genkai genshiryoku hatsudensho; Genkai NPP) is located in the town of Genkai in the Higashimatsuura District in the Saga Prefecture in Japan.
It is owned and operated by the Kyūshū Electric Power Company.
The reactors were all built by Mitsubishi Heavy Industries and are of the 2 and 4-loop M type pressurized water reactor.
Unit 3 has been selected as a special Plutonium fuel test case.
The plant is on a site with a total of 0.87 square kilometers.
Saga does not lie on a fault line and receives the fewest earthquakes in Japan.
History
2011 restart, controversy and reclosure
In early 2011, Units 2 and 3 were suspended for routine maintenance. Following the Tohoku earthquake, Kyushu Electric voluntarily sought reapproval with the town of Genkai and Saga prefecture to make sure that there would be no objection to turning the reactors back on. Negotiations extended several months past the normal restart time. Because Units 2 and 3 were not restarted for the summer, Kyushu was expected to have an electricity shortage and only be able to meet 85% of normal summer needs.
This brief starts where responsible research should: with the source description of “Genkai Nuclear Power Plant” as nuclear power plant. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as nuclear power plant. Its deeper value depends on whether names, dates, institutions and citations support that framing.
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 Jan 21, 2026. The linked authority identifier is Q1513575. Authority coordinates are 33.516, 129.837. 2 of 3 selected statements include explicit references; 1 carry qualifiers and 1 use preferred rank. The first chronological checks are 2011.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
