The Fukushima Daini Nuclear Power Plant was a large power station in Japan. It was located in the towns of Naraha and Tomioka. These towns are in the Fukushima Prefecture. The Tokyo Electric Power Company (TEPCO) operated this plant.
This plant had four nuclear reactors. A nuclear reactor is like a special engine that uses nuclear energy to create heat. This heat then makes steam, which spins turbines to generate electricity. The plant is sometimes called Fukushima II Nuclear Power Plant. This is because "Daini" means "Number 2" in Japanese.

How the Plant Worked
The Fukushima Daini plant used a type of reactor called a Boiling Water Reactor (BWR). In a BWR, water boils inside the reactor. This creates steam directly. The steam then goes to a turbine to make electricity.
Who Built the Reactors
Two different companies built the reactors at Fukushima Daini.
The 2011 Earthquake and Tsunami
On March 11, 2011, a very strong earthquake hit Japan. A huge tsunami followed it. All four reactors at the Fukushima Daini plant automatically shut down quickly and safely. This quick shutdown is called a "scram." It is a safety feature to stop the nuclear reaction.
After the Disaster
By March 15, 2011, all reactors at the plant were safely shut down and cooled. This is known as "cold shutdown." It means the reactors were stable and no longer a danger.
In June 2011, about 7,000 tons of seawater from the tsunami were still inside the plant. TEPCO wanted to release this water back into the ocean. However, about 3,000 tons of this water had some radioactive materials in it. Japan's Fisheries Agency did not allow TEPCO to release this water. They wanted to protect the ocean and sea life.
Emergency Over
Japan's Prime Minister announced that the nuclear emergency at the Fukushima Daini plant was over. This happened on December 26, 2011. The plant was later closed down permanently in November 2013.
