When it comes to reducing production variability (providing a near-baseload) spreading production units out at continental scale is key ( Europe: https://www.imperial.ac.uk/news/180592/european-cooperation-... ),

A nuclear sub throws away uselessly generated electricity. Doing so in a civilian environment would be economically absurd. Nuclear's load-following capacity is quite limited and not sufficient for a grid: https://news.ycom

Indeed. A larger grid enhances our ability to tackle any problem (to cope with any broken production unit or powerline) and to select which unit will generate power (thus offering more options, for example from an economic perspective). Th

Packing a CPU along with many hard drives into a small box implies cooling, and therefore noise. A large-diameter and rather slow fan fixes this, bumping up the volume. This is often-neglected while designing.

Uranium was cheap from the 1960 until now, bar ~3 years around 2007 (a 'Bubble'), however research towards ways to not depend on it (mostly towards breeder reactors) was very intense in many nations from the 1950's to 2000, b
