Although renewable + bess still wins according to most recent studies on that matter, cost comparison between nuke and renewable / Bess is not that useful. Assumptions on the longevity of nuke reactors, for example, helps little if the fleet of reactors end up constantly break down and require repairment as in France and Belgium. So lcoe of nuke over long time span is highly uncertain and contingent; even in construction phase nuclear projects already entails higher risk in time and budget overrun than renewables. Plus the positive feedback loop of learning curve, evident in renewable and Bess, is not so visible for nuclear.

What is more useful for sake of current policy discussion is deployment rate and scalability, which renewable plus batteries clearly wins.
