<p>A storage arrangement for radioactive waste includes a storage bore hole defined by walls of a rock formation, vessels containing radioactive waste deposited in a vertical series in the storage bore hole and a sealing closure situated in the storage bore hole above the uppermost vessel. The sealing closure is a prefabricated solid body (or several such bodies in a vertical series) closely conforming, along its circumference, to the shaft walls. The material of the closure is an alkaliresistant heavy bitumen having a density of at least 1.35 g/cm3.</p> |
