The lobbying effort in the mid 2000s for a "nuclear renaissance" was absolutely a tour de force. It passed laws in US states that put all construction economic risk (the biggest risk of nuclear) onto rate payers rather than the utilities that start nuclear construction projects. These sorts of shady laws sneak through state legislatures all the time, but these ones in particular were the only reason that utilities in Georgia and South Carolina embarked on construction projects. Of course, these have been massive economic and management failures, as nuclear too often is. All the US/UK efforts are echoes from that lobbying push.

And in the mid 2000s, nuclear seemed to be a much better idea. Solar and wind were more expensive, not far less expensive, than estimated nuclear costs. It seemed like nuclear was going to be an absolutely essential part of a carbon neutral or negative society.

Fifteen years later, we have had an energy technology revolution, and we are still in the middle of it. Personally, I don't see a future for nuclear, and for that matter I see only niche applications for thermally generated electricity. Other technology will undercut the steam turbine driven electricity that has been the basis of grids for a century. We might have some chemical storage in hydrogen, methanol, methane, or longer carbon chains that comes from atmospherically extracted CO2 for use in extreme scenarios, but it also seems likely that long-duration battery storage (e.g. vanadium flow batteries) will get cheap enough to replace even that.
