Rare photographs of one of the bathyscaphes used to lower liquidators into the ruins of Reactor 4.

The Sarcophagus of Chernobyl Unit 4 was constructed on top of the ruined reactor hall, using the existing structure as support for its massive weight. Engineers were unsure at the beginning of construction if the building could even support parts of the Sarcophagus. Initially, engineers could only find locations to place the prefabricated pieces of the Sarcophagus using photos taken from the helicopters above the reactor building. On a few occasions, men were sent to scout out potential locations for these structures on foot via passages in the plant. This proved extremely dangerous, and so another solution was brought forward by NIKIMT, a Soviet think tank responsible for several other innovative solutions within the zone; a twenty-one ton lead box with a single leaded glass window 30 centimeters thick. It was equipped with air filters that filtered the air to nearly 100% purity, allowing liquidators to work around the reactor for several hours at a time. Designed to accommodate up to four men, they were affectionately named the batiskaf, or bathyscaphe. These monstrous boxes would be attached to the hook of one of the cranes operating at the site by a short cable and lowered into the reactor hall. This allowed engineers to more closely assess the condition of the structure and find locations to rest the massive beams that held the roof of the Sarcophagus up. Those who worked in the bathyscaphe, known jokingly as “Cosmonauts”, communicated with the operators of the cranes via radio. Work could also be conducted through ports in the walls, through which a manipulator arm could be extended. It was also used on the rare occasion that welding was required on the Sarcophagus. Without this equipment, the Sarcophagus would not have been completed safely. It was also used after the completion of the Sarcophagus to monitor the condition of the construction and reactor hall, until it was retired in 1988 due to instability issues.

Once again, my apologies for low quality images. A few of these images are so rare that I could only find them in one place.

[Image descriptions: Top left image: The bathyscaphe is a large white metal box about seven feet tall, four feet long, and four feet deep, with a single square window. It has several lifting cables attached to its roof and several pipes jut out from it pointing towards the ground to keep it from falling over.

Top right image: they bathyscaphe in ‘flight’.

Bottom left image: The bathyscaphe from another angle, showing the single porthole.

Bottom right image: This is a photo of the bathyschape’s interior. Two manipulator arms sit below the window, and a small stool is welded onto the floor where an operator could sit.

PS feedback on my image descriptions is very much appreciated and helpful. I am new to this, but I think everyone has the right to learn and experience history and if you have any suggestions or comments on how to improve my descriptions please do not hesitate to reach out! I am more than happy to provide more detailed image descriptions as well upon request. Many thanks for your interest!]
