And HPC £130/MWh is a specific business arrangement for a specific contract in a specific country for a specific company building it and operating according to a specific business model. But the consequence of the very definition of median is that there’s also projects with LCOE much lower than $60/MWh, for example for Olkiluoto 3 it was around 40 EUR (and that was including all the delays etc), because Finland secured a very rigid contract where the supplier was paying for any losses while UK seems to be mostly interested in pleasing foreign investors.
But using this case to bash nuclear power in general makes just as much sense as bashing public water utilities for how troubled British water companies are.
