Abstract
A container holds radioactive material. A sub-criticality controller protects the radioactive material from reaching a criticality from contact with the water. The sub-criticality controller includes a metallic composition having at least one metal component and at least one borate component bonded to the at least one metal component. The metallic composition forms borates when the metallic composition contacts the water.
Claims10
A repository for storing radioactive material adjacent to water, the repository comprising:
- a container for holding the radioactive material;
- and
- a sub-criticality controller for protecting the radioactive material from reaching a criticality from contact with the water;
- wherein the sub-criticality controller includes a metallic composition having a metal component and a borate component bonded to the metal component;
- and
- wherein the metallic composition forms a second borate from the borate component reacting with the metal component when the metallic composition contacts the water.
