This is discussion about nuclear power generation, not of nuclear weapons, though. Quite different things. Nuclear, esp. thermonuclear weapons are indeed designed to inflict untold damage.
Sure, but since someone brought the military as an argument for an example of safe nuclear power generation and since AFAIK military forces never did civil nuclear power generation then I believe it's fair game to bring a counter-example to that ^^.
Jokes and gentle jabs apart I am all for exploring the option of SMR and set things up with the Navy's assistance or the government's military forces (also through knowledge transfer if needed and/or career paths, etc.). À la Star Trek.
