I guess you mean me, and I can't give a definite answer of course, it's complicated. I can mention some things I think should be considered.

- Solar is bad in Finland during the winter, but good during the summer. Whatever other fuel is used during the summer now can instead be offset to winter. Even natural gas, but preferably imported wind, hydro and such.

- Solar was not an option when Finland decided to build o3. They couldn't have chosen solar instead, back then.

- Finland is a net exporter of electricity, and is in fact exporting a similar amount as o3 produces manually. So basically Finland didn't really need o3 for themselves, they built it to sell electricity.

- When other countries add lots of cheap solar, it will be difficult to sell nuclear since it's much more expensive.

- If the price forces o3 to close ahead of time, Finland still has to pay for it, and its waste, for decades if not centuries.
