According to the World Nuclear Industry Status Report 2017, India is third in the world in the number of nuclear reactors being installed, at six, while China is leading at 20. The number of nuclear reactor units under construction is, however, declining globally for the fourth year in a row, from 68 reactors at the end of 2013 to 53 by mid-2017.
The report further reveals that most nuclear reactor constructions are behind schedule, with delays resulting in increase in project costs and delay in power generation. There are 37 reactor constructions behind schedule, of which 19 reported further delays over the past year. In India itself, five out of the six reactors under construction are behind schedule. Eight nuclear power projects have been under construction globally for a decade or more, of which three have been so for over 30 years.
The report also documents the financial crisis plaguing the industry. Russia and the U.S. shut down reactors in 2016, while Sweden and South Korea both closed their oldest units in the first half of 2017.
