> The Obninsk power plant has been connected to a grid in 1954

Are you aware that Obninsk was a "closed" city and wasn't marked on the Soviet maps initially?

So whole town was classified, among the power plant.

Why is that relevant at all to the discussion?

This is factually false. Obninsk was not a "closed" town. As soon as it got town status, it wasn't closed.
