My problem with fission reactors is they take a really long time to get running whereas solar can be deployed quickly, even in areas that are underdeveloped. We need to decarbonize global electricity production at a rate far too fast to build nuclear reactors for everyone in the world.
Those solar panels also must be manufactured, which require building more factories and mines. In the end, the difference in industrial investment scale is not that important.
