For the history nerds, I couldn't verify the picture with 100% certainty, but I'm pretty sure it's a picture from the control room in the Obninsk Nuclear Power Plant, the first grid-connected nuclear power plant in history (source 1, source 2).

It's possible that it's another power plant with a similar control panel. I'm not sure who the scientist are. Some sources I saw mention Igor Kurchatov as one of the scientists, but there's a whole myth about him never shaving his beard (which neither scientist pictured have) that I didn't bother to verify. Besides being in this project, Kurchatov helped build the first Soviet atomic bomb, and has a whole array of things named after him, notably the Kurchatov Institute.

In 1957 he received the Lenin Prize and four times the Stalin Prize and the State Prize of the USSR (1942, 1949, 1951, 1954). He was the hero of socialist work three times (1949, 1951, 1954).
