The original lifespan of an NPP is most often a matter of accounting : it's the time it takes to amortize the initial investment, including compound interests.

Of course, this is measured in decades. When the time comes, a major overhaul is most likely a good idea, which means new investments and a new multi-decade business plan. The bottom line, however, is that you get a brand-new NPP almost for free.

Centenarian NPPs will exist sometime this century.

E.g. : Beznau

It all depends wether you prefer to trust investment bankers or climate scientists.

Also, wind and solar do not exist. It is always wind and solar and an equal dispatchable capacity, which is most often fossil-burning, carbon-spewing. A true comparison would include the cost of these double infrastructure and double-maintenance, as well as the costs of continuing emissions of carbon dioxide.

This oft-cited Lazard study completely ignores one fundamental characteristic of electric grids : production is strictly on-demand, zero-stock and zero-delay.
