Could they really be economical though? There is potential for harm (including terrorism) that must be insured against, you also need to pay a premium for the land compared to solar/wind since few want to live nearby. The construction timelines are huge compared to solar/wind and you don't have the economies of scale that drive prices down.

Nuclear easily beats coal if we include the environmental costs but it's also up against solar, wind, geothermal, and tidal options which have seen huge efficiency gains in the last decade.
