* Nuclear fusion reactions have the potential to be safer and generate less radioactive waste than fission. * These reactions appear potentially viable, though technically quite difficult and have yet to be created on a scale that could be used in a functional power plant. * Fusion power has been under intense theoretical and experimental investigation since the 1950s.
As of 2005, nuclear power provided 6.3% of the world's energy and 15% of the world's electricity, with the U.S., France, and Japan together accounting for 56.5% of nuclear generated electricity. In 2007, the IAEA reported there were 439 nuclear power reactors in operation in the world, operating in 31 countries. As of December 2009, the world had 436 reactors. Since commercial nuclear energy began in the mid 1950s, 2008 was the first year that no new nuclear power plant was connected to the grid, although two were connected in 2009.
* Presently, waste is mainly stored at individual reactor sites and there are over 430 locations around the world where radioactive material continues to accumulate. * Experts agree that centralized underground repositories which are well-managed, guarded, and monitored, would be a vast improvement. * There is an "international consensus on the advisability of storing nuclear waste in deep underground repositories",but no country in the world has yet opened such a site.
