The West has already abandoned its leadership in nuclear energy; for the future of nuclear power we must look to China and India.
Despite the renewable hype, both of these countries have coal-dominated power systems, both for the exising fleets and for new construction (China has unusually large hydro resources and deployment, but the other non-fossil energy sources are small).
Both countries boast of large renewables investments. Both are continuing to build coal-fired power plants. But also, both are building new nuclear, at about the same rate as solar or wind. Most reports seems to say the power cost of renewables is less than that from nuclear, but the lower integration cost (including fossil fuel backup) makes nuclear more economical in these countries.
According to Chinese policy, large light water reactors are the technology of choice, with new builds switching to sodium cooled fast reactors at some point in the future, ultimately yielding a mixed fleet. In India, nuclear builds are split between domestically designed large heavy water reactors and imported (Russian) large light water reactors. Both are already building their first-of-a-kind fast reactors.
There don't seem to be any serious analysts who think storage will become so cheap that it will fix the integration/backup cost of renewables. A large boom in fossil gas production would help reduce renewable system costs, but they have a very long way to go to reach that level of gas production.
Small reactors (SMRs) are partly interesting to US utilities because our national grid is divided is many separate jurisdictions. China and India don't have that situation, so 1GW class reactors are just fine. The US grids are being interconnected more and more (in part due to windpower deployments). This new level of interconnection will make it easier for us to use large reactors also, so we may eventually follow in the footsteps of China and India. The SMRs do help build industry experience quickly, but that is a short term effect, if you goal is to replace the entire fossil fuel generation fleet over a 40 year period (i.e. we need 12 GW per year of new construction, adjusted for capacity factor).
