China's rapid nuclear expansion will result in it overtaking the U.S. as the nation with the largest atomic power capacity by 2026, according to BMI Research.

The world's second-biggest economy will almost triple its nuclear capacity to nearly 100 gigawatts by 2026, making it the biggest market globally, analysts said in a note dated Jan. 27. The nation added about 8 gigawatts of nuclear power last year, boosting its installed capacity to about 34 million kilowatts, according to BMI.

China has committed to boosting nuclear power, which accounted for about 1.7 percent of its total generation in 2015, to help reduce reliance on coal, which accounts for two-thirds of its primary energy. The nation has 20 reactors currently under construction, according to the International Atomic Energy Agency. Another 176 are either planned or proposed, far more than any other nation, according to the World Nuclear Association.
