Actually Rosatom refuses to operate the plant and it's still operated by the Ukrainian Energoatom. Hm, I wonder why is that? Maybe so they could put the blame on Ukraine when they blow that shit up?
You don't need RSS if you using Invidious or Piped (LibreTube). Just create an account and subscribe to channels (or import from YouTube).
You can import them directly from YouTube, but YouTube won't show preview images or video description.
Or alternatively you can first import them to Invidious/Piped and then export RSS feed from there, which is probably the better way.
Subscription import seems not very reliable in NewPipe. Half of the time import just doesn't work and doesn't even show any errors or anything. My guess that's the reason you don't have your subscriptions. Because they were not imported correctly.
Anyways, I think you'll be better off not using NewPipe subscriptions at all. Because there is no way to export them and merging multiple imports is very problematic. I recommend you using RSS feed from Invidious (make sure you use multiple instances for your RSS feed or you gonna get errors) or Piped (you need account to use RSS) and some sort of RSS reader (I use Flym).
