Paluel Nuclear Power Plant, France
The Paluel Nuclear Power Plant, located 40km away from Dieppe, France, is currently the seventh largest NPP in the world, by net capacity. The plant is spread across 160ha on the waterfront of the English Channel and uses water from the Channel for the cooling.
The plant is owned and operated by EDF and consists of four PWRs with a gross installed capacity of 5,528MW (1,382MW each) and net design capacity of 5,200MW (1,300MW each).
Construction of the nuclear power station began in 1977. The first two units of the plant were connected to grid in 1984. The third and fourth units were commissioned in 1985. Paluel is the second largest French NPP, after Gravelines.
Cattenom Nuclear Power Plant, France
The 5,448MW (gross) Cattenom Nuclear Power Plant is located in Cattenom, France. The power plant is owned and operated by EDF. The net capacity of the plant is 5,200MW, which is similar to that of Paluel NPP, the seventh largest nuclear power plant in the world.
Cattenom Nuclear Power Plant consists of four PWRs rated at 1,362MW each. Construction of the plant started in 1979 and commercial operations began in April 1987. The fourth reactor of the plant was connected to grid in 1991.

Fukushima Daini Nuclear Power Plant, Japan
The Fukushima Daini or Fukushima II nuclear power plant located in Naraha, Fukushima Prefecture, Japan, would have ranked as the tenth biggest nuclear power plant in the world if operational. The four reactor units of the Fukushima II were automatically shut down due to the Great East Japan Earthquake in March 2011.
The 4,268MW (net) plant is owned and operated by TEPCO. It consists of four BWR units with a gross capacity of 1,100MW and a net capacity of 1,067MW each.
The powerful tsunami waves triggered by the 9.0 magnitude undersea earthquake caused meltdowns at three reactors in the Fukushima Daiichi NPP while Fukushima Daini survived the disaster because of the emergency shutdown of its reactors. All four reactors of Fukushima Daini have since been maintained in cold shutdown. In June 2018, TEPCO informed that it was considering the decommissioning of the plant.
