I looked at these reports, I think this has to do with the Ukraine nuclear plant....they are going to do something to it and these people and equipment are for that operation and not to launch tactical nukes.
Good luck with that. There are four generations of kit in Zaporizhzhia NPP, only the oldest was constructed entirely within the Soviet Union. All six reactors had safety systems from commercial providers installed years ago.
And the last reactor setup was constructed with no legacy Soviet resources and minimal Russian supply chain reliance.
Unless Russia is looking to make massive downgrades it’s not clear why they’d mess about with any of the systems at any Ukrainian NPP.
