The french costs keep going up. The problem with nuclear is that smart people sit around thinking up all the 1% ways that the plant could meltdown and making iterative changes to designs to mitigate them. Managers generally approve them since its better not to be the person making the call on something that caused a meltdown as long as the increase in the cost is marginal. The sum total of a lot of marginal increases in the cost though is a negative learning curve. Solar and wind don't have this because nobody worries about a solar plant blowing up and contaminating the surrounding countryside and cost a trillion dollars to clean up, so it keeps getting cheaper.
