Nuclear Power Plants Under Construction

As of March 2021, the World Nuclear Association lists 54 power reactors under construction where the first concrete for reactor has been poured.  Construction on five of these is currently suspended: Angra 3 (Brazil); Ohma 1 and Shimane 3 (Japan); Khmelnitski 3&4 (Ukraine) [World Nuclear Association 28 Mar 2021].

Of the remaining 49 power reactors under construction:

      • 1 is a 25 MWe small Pressurised Water Reactor (PWR) being built in Argentina,
      • 1 is a 211 MWe High Temperature Pebble Bed reactor (HTR-PM) being built in China,
      • 1 is a 500 MWe Fast Breeder Reactor (FBR) being built in India,
      • 2 are 600 MWe Fast Reactors (CFR-600) being built in China,
      • 3 are 700 MWe Pressurised Heavy Water Reactors (PHWR-700) being built in India,
      • 2 are 471 MWe pressurised water reactors (VVER-440) being built in Slovakia, and
      • 39 are larger pressurised water reactor between 1000 and 1720 MWe being built in 14 countries. 

The countries building the 39 larger PWRs (over 1000 MWe) are Bangladesh 2, Belarus 1, China 14, Finland 1, France 1, India 2, Iran 1, South Korea 4, Pakistan 1, Russia 2, Turkey 3, UAE 3, UK 2 and USA 2. Twelve of these reactors are expected to be connected to the grid in 2021.

The main larger PWR designs under construction are:

      • VVER – 11 under construction in Russia, Turkey, Bangladesh, Iran and India
      • Hualong One – 10 under construction in China and Pakistan
      • APR1400 – 7 under construction in South Korea and UAE.
      • EPR – 4 under construction in Finland, France and UK
      • AP1000 – 2 under construction in USA
      • CAP1400 – 2 under construction in China
