Shared by one of our readers, Steve, this is a video from the era when Soviet documentaries were still being translated into foreign languages. This particular one tells a story of an atomic icebreaker that could sustain people deep into the polar ice fields without any need of external sources of heat or fuel, which was really groundbreaking technology at the time and is still pretty cool even now.
There is one more documentary on atomic power in Soviet Russia as a bonus inside:
It tells the story of the Beloyarsk Atomic plant, which is said to be the second atomic power plant to be built in Russia. By the way, the world’s first one was from Russia too (as per Wikipedia).
The documentary tells the story of its construction and day to day operation routines.
