The Fukushima disaster has lead the French government to release novel cost information relative to its nuclear electricity program allowing us to compute a levelized cost. We identify a modest escalation of capital cost and a larger than expected operational cost. Under the best scenario, the cost of French nuclear power over the last four decades is 59. €/MWh (at 2010 prices) while in the worst case it is 83. €/MWh. On the basis of these findings, we estimate the future cost of nuclear power in France to be at least 76. €/MWh and possibly 117. €/MWh. A comparison with the US confirms that French nuclear electricity nevertheless remains cheaper. Comparisons with coal, natural gas and wind power are carried out to find the advantage of these Financial support from Generalitat de Catalunya (XREPP), Ministerio de Economia y Competitividad and Ministerio de Ciencia e Innovaci-n (contract ECO2010-16353) are gratefully acknowledged.
