Nuclear reactors connected to the grid in 2022 had a median construction time of 89 months or almost 7.5 years. During the period in consideration, the median construction time for nuclear reactors was the longest for reactors connected between 1996 and 2000, at 120 months.
Nuclear reactors with longest construction time
In 2022, Finland’s Olkiluoto 3 and France’s Flamanville 3 were the world’s nuclear reactors with the longest actual construction time compared to the projected schedule. Olkiluoto 3 was connected to the grid in 2022 after 101 months of construction works.
