First episode didn’t get into too much detail of what the actual cause was. It was centered on the explosion, immediate aftermath, and ensuing confusion. Plenty of back and forth with “it’s not that bad/yes it is”; “keep the core covered/there is no core.”
As I mentioned in another thread; I already had issues with the trailer, but I enjoyed the first episode. Giving them enough rope to hang themselves with so to speak.
As a disclaimer, I operated/maintained nuclear reactors for over 20 years.
I mean.....really. What doe a "nuclear reactor operator" actually do?
