* The USA is the world's largest producer of nuclear power, accounting for more than 30% of worldwide nuclear generation of electricity.
*The country's 104 nuclear reactors produced 807 billion kWh in 2010, over 20% of total electrical output.
* Following a 30-year period in which few new reactors werebuilt, it is expected that 4-6 new units may come on line by 2020, the first of those resulting from 16 licence applications made since mid-2007 to build 24 new nuclearreactors.
* However, lower gas prices since 2009 have put the economic viability of some of these projects in doubt.
* Government policy changes since the late 1990s havehelped pave the way for significant growth in nuclear capacity. Government and industry are working closely on expedited approval for construction and new plant designs.In 2010, the US electricity generation was 4361 billion kWh gross, 46% of it from coal-fired plant, 23% from gas, 19% nuclear and 6.5% from hydro. Annual electricity demandis projected to increase to 5,000 billion kWh in 2030, though in the short term it is depressed and is not expected to recover to the 2007 level until about 2015. Annualper capita electricity consumption is currently around 12,400 kWh. Total capacity is 1027 GWe, less than one tenth of which is nuclear.
The USA has 104 nuclear powerreactors in 31 states, operated by 30 different power companies. Since 2001 these plants have achieved an average capacity factor of over 90%, generating up to 807 billionkWh per year and accounting for 20% of total electricity generated. Capacity factor has risen from 50% in the early 1970s, to 70% in 1991, and it passed 90% in 2002.
