Nuclear power (including the fuel cycle) releases fewer greenhouse gases into the environment than coal-burning plants. Developing technology is producing new nuclear power plants - (pebble-bed modular reactors) that are safer and more cost effective to build and operate. Helium is used rather than water to turn turbines. Vitrification can be used to seal the spent fuel for safer storage. Emissions from coal burning plants also may release a significant amount of sulfur oxides and mercury into the atmosphere.
Arguments against nuclear power include producing spent fuel that can provide a way for terrorists to develop nuclear weapons, the need for fossil fuel to mine and enrich uranium, and the safety concerns from nuclear power plant accidents.
