Moreover to blame the current price hikes on the nuclear shutdown is dishonest at best 8 of the 17 nuclear reactors in Germany were shut down in 2011 (and IIRC all of the were 40 years and older) without this causing a big price hike. Of the remaining only the last 3 were shut down in 2021 (the youngest being 31 year, with IIRC original permits being 40 years). It is also false to say that Germany replaced nuclear with coal, because coal reduced significantly as well during the same time, while renewables raised rapidly.
One could just as well argue that it's Frances fault for not investing in renewables at all (growth of renewables is tiny in France compared to Germany). Also of note is that nuclear relies just as much on gas peakers as renewables.
It's also funny that you blame the greens for the 12/2020 ringhals shutdown, because it was shut down by vattenfall due to low profitability[1]. This was one of two shutdowns the other was in 2019, so both also had very little to do with current prices.

Another thing, I related to the shutdown of Swedish nuclear power, not German nuclear power so why did you bring up those numbers on Germany? It is very clear that the closure of those Swedish nuclear power plants - which could have run until 2036 without problems, by which time replacements would have been in place - has made the electricity supply in Sweden less reliable and the price swings more frequent and intense. The oil-fired peak power plant in Karlshamn would normally only be fired up in the cold of winter but last year it was used in the middle of summer to avoid a brown-out in Stockholm.
Regarding the plant shutdown, you nicely ignored the fact that contrary to your assertion it was just down for economic reasons. Sure Vattenfall could have kept it running and made losses and now that demand increased they would have stopped prices going up (likely not because the big winners of the price hikes are the nuclear power plant operators). They could have also build windfarms for that money that likely would have taken prices down.
Haha det är så kul med kärnkraftshögermän som låtsas att vi i MP motarbetat kärnkraft ”i smyg” för att sen skylla på marknaden. Löjligt. Jag tar hemskt gärna cred för nedlagd kärnkraft. Utan MP hade nog flera av de nedslängda reaktorerna rullat vidare.
...which translates to:
Haha it's so much fun with nuclear right-wingers who pretend that we in the MP ("Miljöpartiet") opposed nuclear power "secretly" and then blame the market. Ridiculous. I'm terribly happy to take credit for discontinued nuclear power. Without MP, several of the closed ("nedslängda" means "dropped", I guess he meant to write "nedstängda" which means "closed") reactors would probably have rolled on.
So, no. Not "the market" but politics pushing that market in a certain direction.

These two claims aren't contradictions though.
It is both possible that nuclear tech has improved a lot, and that newer reactors would be better, but the alternative of "no reactors at all" is much worse than even running the existing ones beyond their design lifetime.
- the "green" party "Miljöpartiet" ("Party for the environment") has forced the premature closure of half of the nuclear power plants, going so far as to replace the leadership of the state-owned power consortium "Vattenfall" when they refused to fall in line. They actually boast about closing those nuclear power plants, indicating the disconnect between their party's name and its goals.
- Sweden has increased its exchange with other European power distribution networks which caused the higher prices on the European market to have a larger influence on local pricing. The country is divided into 4 pricing zones, the northernmost 2 of which have lower prices - closer to the price paid by all Swedes before deregulation and the introduction of the controlled market "Nord Pool" - than the rest.
