Meaningless given reactors in the US are around 60 years old and still running.
Just like the LCOE for Victorian coal generation is a waste of time given they were long ago paid for and could keep running for many years more if there was no war on their existence.
And the LCOE is also useless if the price of building into the system all the backup, energy storage (batteries) and Rewiring of the system needed is not included into the calculation.
