The WNO report that nuclear power capacity worldwide is increasing steadily, with over 60 reactors under construction in 15 countries. Most reactors on order or planned are in the Asian region, though there are major plans for new units in Russia. Significant further capacity is being created by plant upgrading. Plant life extension programs are maintaining capacity, in the U.S. particularly.

Today (October, 2015), there are some 437 nuclear power reactors operating in 31 countries plus Taiwan, with a combined capacity of over 380 GWe. In 2014 these provided 2,411 billion kWh, over 11% of the world electricity. Over 60 power reactors are currently being constructed in 13 countries plus Taiwan, notably China, South Korea, UAE and Russia.

Each year, the IEA sets out the present situation and also reference and other particularly carbon reduction scenarios. World Energy Outlook 2014 had a special focus on nuclear power, and extends the scope of scenarios to 2040. In its New Policies scenario, installed nuclear capacity growth is 60% through 543 GWe in 2030 and to 624 GWe in 2040 out of a total of 10,700 GWe, with the increase concentrated heavily in China (46% of it), plus India, Korea and Russia (30% of it together) and the U.S. (16%), countered by a 10% drop in the EU.

Despite this decrease, the percentage share of nuclear power in the global power mix increases to only 12%, well below its historic peak. Low-Nuclear and so-called High-Nuclear cases give 366 and 767 GWe nuclear respectively in 2040. The low-carbon 450 Scenario gives a cost-effective transition to limiting global warming assuming an effective international agreement in 2015, and this brings about more than doubling nuclear capacity to 862 GWe in 2040, while energy-related CO2 emissions peak before 2020 and then decline. In this scenario, almost all new generating capacity built after 2030 needs to be low-carbon.
