So I think most of this article is well explored, if we ignore the speculated Russian assistance related stuff.
I personally did not spend time looking through the thread to see and understand just the type of reactor, efficiency and power generation. His number of 1.3MWe pretty much lines up with what some of what had estimated that they would need.
I think he underestimates just how great China's Lithium ion battery tech is and the charging tech behind that. Using Kilo as a basis for how long it would take mini nuclear reactor to recharge battery pack doesn't make sense to me.
I would've liked to have seen something from the article on how using such a smaller reactor with battery affects noise level compared to Stirling AIP sub. We've done our own discussions on which really noise making components are still present on such a system, but Chris has pretty good knowledge of sub reactor tech, so I think he would have good insight here.
