Mining beneath Chernobyl reactor assemblage #4

Heroic work of Ural miners under destroyed unit #4, mining shaft from unit #3 in order to create capsule for liquid nitrogen cooling device, which would prevent molten fuel from escaping concrete "containment" and contaminating ground waters. However, the device was not ever installed and the capsule was filled with concrete creating 2m thick plate. The molten fuel has never reached it. All of miners got high doses of radiation, especially at the entering into the shaft.
