Abstract
There is described an apparatus for the corrosion protection of containers for the long time storage of radioactive materials, especially of spent fuel elements, in suitable geological formations which avoid corrosion of the container even with unexpected occurrence of water, or at least delay and minimize the corrosion. The apparatus consists essentially of sacrificial anodes 2 which are conductively joined to the containers 1 via connections 3.
Claims28
An apparatus for the protection against corrosion of a container means made of metal for the long time storage of radioactive material in a suitable geological formation comprising (1) said container means, (2) sacrificial anode means made of metal conductively connected thereto in said geological formation, and (3) arranged spatially near the container and the sacrifical anode means a material supply which is made of a material having a nobler potential than that of the container means.
