Nuclear power is very expensive  For nuclear power plants any cost figures normally include spent fuel management, plant decommissioning and final waste disposal. These costs, while usually external for other technologies, are internal for nuclear power. Costs are high compared to coal fired generation precisely because the externalities associated with high carbon outputs are not taken into account, whereas similar externalities relating to nuclear generation are. If costs are calculated equivalently to coal power stations then nuclear power is competitive.  Also the cost of construction and decommissioning of nuclear power plants is often overestimated; the French and Swedish nuclear industries estimate decommissioning costs to be just 10 -15 % of the construction costs and budget this into the price charged for electricity1. Nuclear is actually increasing its competitiveness as gas and oil prices rise, new technology makes nuclear power more efficient and construction and decommissioning costs less. An OECD study in 2005 showed nuclear overnight construction costs ranged from US$ 1000/kW in Czech Republic to $2500/kW in Japan, and averaged $1500/kW. Coal plants were costed at $1000-1500/kW, gas plants $500-1000/kW and wind capacity $1000-1500/kW2. The difference, when weighed against nuclear power's other advantages, is thus not that great.  1 'Cost of nuclear power', 2 'The Economics of Nuclear Power', World Nuclear Association, January 2009,
