You are right, it was not LCOE but production cost - I think your quote comes from Wikipedia article, where it was previously described as LCOE but must have been refined as production cost since I’ve last seen it.
Still, the median value in the range of $65 (IPCC 2014) and $69 (NEA 2020) still holds.
My point was more in that neither UK nor US are good examples due to their obsessive fixation on private funding and ownership of the plants. Neither example should be generalised on the nuclear power in general, because it has nothing to do with nuclear power or water utilities themselves, but is caused by specific market failures in these countries.
