While nuclear is one of the most expensive electricity sources, with surprisingly limited fuel reserves given the energy density, it's incredibly safe (despite the reputation) and I think there is inherent value in a diverse supply that can make up for the sticker price.
Also, China is able to build it at a reasonable price (~$40/MWh). It's not destined to be expensive, the price is just a consequence of excessive safety precautions.
