BRATRSTVÍ REPOSITORY IN JÁCHYMOV
From Silver to Uranium
The history of the Bratrství Mine reaches deep into the past of Jáchymov. Originally, silver ores were mined here, bringing enormous prosperity to the town as early as the sixteenth century. Later, attention shifted to other minerals and, during the twentieth century, especially to uranium.
After the Second World War, the Jáchymov region became one of the principal centres of uranium production for the Soviet nuclear programme. Labour camps were established in the area, and thousands of political prisoners worked in the uranium mines. The Bratrství Mine was among the most important mines of this era.
Uranium mining gradually came to an end during the second half of the twentieth century. Some parts of the mine were subsequently abandoned, while others found new uses.
Conversion into a Repository
In the 1970s, a decision was made to use part of the former mine as a radioactive waste repository. Operations began in 1974.
Unlike the Richard Repository, ordinary institutional waste is not stored here. Bratrství is primarily intended for materials containing naturally occurring radionuclides, such as radium and thorium.
The choice of location was not accidental. The Jáchymov region naturally contains elevated levels of radionuclides and also offered suitable underground spaces left behind by mining activities.
Underground Workings
The repository makes use of former mine tunnels and chambers within the Ore Mountains massif. These spaces were technically modified, reinforced with concrete, and equipped with monitoring systems.
Nevertheless, the underground environment has retained the character of a former uranium mine. Damp passageways, heavy supports, and traces of mining activity still recall the period when material for the emerging nuclear age was extracted in Jáchymov.
The atmosphere of the site is further shaped by awareness of the dramatic events associated with the uranium mines and labour camps of communist Czechoslovakia.
What Waste Is Stored Here?
The Bratrství Repository is primarily used for waste containing natural radionuclides. It does not receive spent nuclear fuel from nuclear power plants.
The stored materials include waste from healthcare, research, and industry. The waste is placed in special drums and containers that are registered and monitored in a manner similar to other Czech repositories.
The facility’s capacity is considerably smaller than that of other Czech repositories, and discussions have been taking place for some time regarding its gradual filling.
Present and Future
Today, the Bratrství Repository is operated by the Radioactive Waste Repository Authority. Regular monitoring of radiation levels, groundwater, and the technical condition of the underground spaces is carried out in the surrounding area.
At the same time, the site remains a powerful reminder of the complex history of the Jáchymov region. Few places combine mining traditions, Cold War history, the suffering of political prisoners, and the modern issue of radioactive waste as vividly as this location.
It is precisely this combination that makes Bratrství one of the most fascinating and impressive technical sites beneath the surface of the Czech Republic.
