Patent attributes
Waste capsules for disposal of radioactive materials, including weapons grade plutonium, are made entirely from rock, such as, but not limited to, granite; wherein a cap of such a waste capsule is seamlessly rock welded to a lower body portion of the given waste capsule, to form the given waste capsule, with the radioactive materials inside of a cavity of that waste capsule. The weld region is homogenous with both the cap and the lower body portion. A cooling system may be used during or after rock welding. The sealed and rock welded waste capsule, with the internal radioactive materials, is then loaded into a wellbore system that extends into a deep geological rock repository, thousands of feet below the Earth's surface, such that the waste capsule comes to rest in a wellbore located within the deep geological rock repository. The waste capsule may include insulating material in the cavity.
