The economics side is something I couldn't find reliable data on, but the data I did find didn't suggest a big difference in cost.

Here you go.

Given this discrepancy, nuclear’s history of cost overruns, and the fact new generation designs have never been constructed any where, there is a major business risk nuclear power will be more costly than projected. Recent construction cost estimates imply capital costs/kWh (not counting operation or fuel costs) from 17-22 cents/kWh when the nuclear facilities come on-line. Another major business risk is nuclear’s history of construction delays. Delays would run costs higher, risking funding shortfalls. The strain on cash flow is expected to degrade credit ratings. Generation costs/kWh for new nuclear (including fuel & O&M but not distribution to customers) are likely to be from 25 - 30 cents/kWh. This high cost may destroy the very demand the plant was built to serve. High electric rates may seriously impact utility customers and make nuclear utilities’ service areas noncompetitive with other regions of the U.S. which are developing lower-cost electricity.
