Data centers, the things that physically store and share applications and data, require an enormous amount of energy to run. These giant storage units, responsible for 1-1.5% of global electricity consumption, have traditionally relied on renewable sources like solar and wind but it seems as though renewable energy just won’t be able to keep up with the demand required moving forward.
I’m not making this comment to disagree with your point, but the failure of the SL-1 reactor strikes me as an engineering and process failure more than anything else. The reactor was not designed in a safe fashion, probably because it was designed as a test bed for reactors that could be deployed via airplanes to the Arctic circle. The fact that an engineer was even able to fully remove a control rod, and the fact that removing that control rod lead to a fatal steam explosion make me think that they really tried too hard when they removed weight and volume from the reactor design.
In well designed safety-critical systems, human error should not be able to cause any form of bodily harm. I don’t think it’s a great idea for a private company to be running nuclear reactors on Earth to power something as trivial as a data center (investing in storage + local solar/wind/geothermal/hamster wheel velodrome seems like a more efficient use of resources for one thing), but I also don’t think that SL-1 is the best example to cite here.
As an aside, my high school Physics teacher went on a long diatribe about how the three SL-1 casualties were the only humans ever killed as the direct result of nuclear fission in the context of a nuclear reactor. Looking back on it, I think she was splitting hairs a bit, but it is an interesting point to make.
