A lot of the big tech companies want to build huge, electrical intensive computing centers.
There has been a significant reaction to this because of the cost of electricity. In some areas, the new electrical demand can drive up the cost for everyone in the area, not just the new centers.
They want to negate this issue, so they need quick, reliable, energy. They have concerns about solar and wind being unreliable, fossil fuels destroying the world. That leaves geothermal which only works reliably in very rare locations, hydro which has fish issues (and the total transformation of the areas near dams), and nuclear.
When logical people look at well designed nuclear, they realize that it is far less toxic than fossil fuels, has minimal environmental dangers, and that the main issues are reputation.
Modern, newer designs entice them. They have the issue of being untested, but the 'move fast and break things' motto of Big Tech does not fear the untested. Whether or not this is a good idea for small nuclear technology as opposed to the software/chip business, well I do not know - and neither do they.
It is easy to understand why these aggressive tech bros want the nukes. But I would not want to live near their first facilities. Hopefully they will be smart enough to build them far enough from population centers.
