Marginal cost is fairly low yes but the upfront investment is enormous, especially with the Olkiluoto 3 reactor that was far over budget and way past schedule.

Olkiluoto 3:n ongelmat varmaan omalta osaltaan siivittivät tämän päätöksen suuntaan, eikä noita ydinvoimaloiden rakentajia ole kauhean montaa. Jälkiviisaana olisi voinut ehkä sanoa, että suunnitelmat olisi kannattanut rakentaa tuttujen toimijoiden varaan...

Finland's electricity emissions intensity fell by more than two, from 130 gCO₂e/kWh to 57 gCO₂e/kWh, between 2020 and 2025.
Here's the change in Finland's electricity mix over that time.
Wind rose by 13.9 TWh/yr,
nuclear rose by 9.5 TWh (mostly Olkiluoto 3),
fossil fuel fell 7.1 TWh.

Accusing me of cherry-picking, while you can't even name three countries that back your very bold claims.
3 out of 193.
Again, you cherrypick Olkiluoto, which isn't running that perfect as it should and ONLY profits from EDF and frances' tax payers taking the costs. The other EU-EPR are desasters.

you are not looking at reality. you re trying to cherrypick.
and even then you fail.
the first and worst project of the EPR is Olkiluoto 3
and it STILL delivers power for about 49 €/MWh
a cost in line with wind power.
so from a grid perspective. intermittent power is extremely expencive.

What replaced the fossil-fuelled electricity?
Wind share has risen from 0% in 2010 to 27% in 2025.
Nuclear share stayed at a steady level just above 30% through the 2010s, then jumped to over 40% in 2023 when Olkiluoto 3 came online.
Hydro and biomass have contributed a steady 10%–20% each.

I suppose the basic tenet is: if this speeds up commuting, eases inter-city exchanges & lessens dependence on CO2 emitting planes, & we are the only G7 country that doesn't have HS-trains, it probably ain't so bad. Budgets explode almost always.Ask Finland about cost overruns at Olkiluoto III, e.g.😆

Not sure what is "ridiculous".
Why don't you just admit nuclear is too complex/unreliable
When one takes into account the numerous unplanned outages Olkiluoto 3 experienced in 2023, late 2024, & early 2025, one would expect a more modest attitude towards other more distributed and redundant technos.
