Fukushima Daiichi Nuclear Power Plant
nuclear power plant in Japan
The Fukushima Daiichi Nuclear Power Plant (福島第一原子力発電所, Fukushima Daiichi Genshiryoku Hatsudensho; Fukushima number 1 nuclear power plant) is a disabled nuclear power plant located on a 350-hectare (860-acre) site in the towns of Ōkuma and Futaba in Fukushima Prefecture, Japan. The plant suffered major damage from the magnitude 9.1 earthquake and tsunami that hit Japan on March 11, 2011. The chain of events caused meltdowns, radiation leaks and severely damaged several of its reactors, making them impossible to restart. The working reactors were not restarted after the events.
First commissioned in 1971, the plant consists of six boiling water reactors. These light water reactors drove electrical generators with a combined power of 4.7 GWe, making Fukushima Daiichi one of the 15 largest nuclear power stations in the world. Fukushima was the first nuclear plant to be designed, constructed, and run in conjunction with General Electric and Tokyo Electric Power Company (TEPCO). The sister nuclear plant Fukushima Daini ("number two"), 12 kilometres (7.5 mi) to the south, is also run by TEPCO. It also suffered serious damage during the tsunami, at the seawater intakes of all four units, but was successfully shut down and brought to a safe state. See the timeline of the Fukushima II nuclear accidents.
The March 2011 disaster disabled the reactor cooling systems, leading to three reactors melting down causing hydrogen explosions destroying the containment, subsequently releasing large amounts of radioactivity and triggering a 30-kilometre (19 mi) evacuation zone surrounding the plant; as of February 2025, releases of radioactivity are still ongoing.
This brief starts where responsible research should: with the source description of “Fukushima Daiichi Nuclear Power Plant” as nuclear power plant in Japan. 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 in Japan. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jul 20, 2026. The linked authority identifier is Q114295. VIAF identifies the subject as 147742053. The Library of Congress control number is n80033812. Authority coordinates are 37.421, 141.032. 5 of 7 selected statements include explicit references; 2 carry qualifiers and 2 use preferred rank. The first chronological checks are 2011, 1971 and 2025.
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.
