If cost is the entire point of SMRs, prepare to be very disappointed.
Of course we can store energy, we've been doing it for thousands of years. Pumped hydro, flywheels, various battery chemistries, compressed air, molten salt, green hydrogen, and so on are all viable and should be used where appropriate. For instance pumped hydro is excellent if you have the terrain.
If it is that easy, show me one example where any of those technologies have been deployed at a scale required for even a day usage of an entire nation?
Truth is, its hard to do. We will get there, but not sufficiently fast for where we need, hence the continuing need for nuclear.
Iceland, Paraguay, Costa Rica, Norway.
We're ahead of where you think we are, no need for nuclear.

Not a single one is an example of what I asked.
Maybe the solution for the UK is to create mountainous rivers or move the country to techtonically active parts of the planet.
I gave you what you asked. I assume you've heard of Dinorwig? That's in Wales. Plenty of elevation changes there and in Scotland.
