Zusammenfassung:Subterranean storage cavities for nuclear fuel are constructed from concrete which is radiation proof. The cavities are constructed in chalk or gypsum deposits. The walls of the cavity are first lined with a radiation shield before the concrete is applied. The stores can be used for fuel which is being held for reprocessing. It can also be used as the final store for spent fuel. The cavities can occur in coal mining operations or in rock salt deposits. The concrete should absorb and decelerate fast neutrons and gamma-radiation.
