Fission is already not competitive, so a technology much more expensive to build and operate is even less so. In ten years, solar and wind will be even cheaper than today, and will be supplying most of our energy needs.
Fission is non-competitive only because governments don't want it to be. France's nuclear fleet built in the 60s/70s with more primitive tech has capital/operating costs of 7c/kWh, which is fairly similar to commercial solar or wind in France - and is the cheapest option once you double the cost of the latter to account for extra storage/smart grids/other intermittency handling.
(Not every place is Southern California where there are no clouds and the sun shines all year. Solar is cheap in some places, but not at high latitudes.)
Fission is not competitive because of high operational expenses, very long construction, and very high capital commitment, none of which will follow plummeting solar/wind/storage costs. So it gets less competitive with each passing day.
