Only if you ignore reliability issues with nuclear, such as France having to take a lot of reactors offline at the same time to check for cracks. The comparison has to be fair.
Second, the could have kept those plants operating and taken a more piecemeal approach to fixing the cracks. They shouldn't have, and didn't, because you really want that triple or quadruple redundancy in your cooling systems, but they could have if push had come to shove, the plants were still operational.
But since there was plenty of capacity available, they could afford to take those plants offline and do the checks and repairs all at once.
Intermittent renewables afford you no such optionality.
If the sun don't shine, the sun don't shine.
If the wind don't blow, the wind don't blow.
These cracks are not the only factor for the poor performance on nuclear in 2022 : several reactors had to do their 10-year maintenance (grand carénage), which had been delayed because of the pandemic.
It's hard to extrapolate reliability issues from an event that happened once in 30 years.
Nuclear and reliable renewables for base load, intermittent renewables for intermittent load where and when it matches.
Wind/solar are not cheaper. Per kWh they are more expensive. Thanks to China, they are a lower and smaller-grained capital investment.
