Solar and wind power are dependent on the weather to generate power, where nuclear power is not. I agree that there are many ideas on how to store the energy from solar and wind power, but how many of them is used on such large scale that it makes a difference on the grid?

Out of topic but do you have any data that shows that the baseload is obsolete? I have a hard time to believe that based on the definition from https://www.sciencedirect.com/topics/engineering/baseload

Baseload refers to the minimum level of demand on an electrical supply system over a 24-hour period, with baseload power sources being those plants that generate dependable power to consistently meet this demand.
