Injectable sacrificial material systems and methods to contain molten corium in nuclear accidents
| DWPI Title: System for delivering carbonate-based material within nuclear reactor containment, has nuclear reactor vessel contained within nuclear containment, storage tank containing mass of carbonate-based material, and gravity fluid delivery system for transporting carbonate-based material within vessel |
| Abstract: Systems and methods for injecting a carbonate-based sacrificial material into a nuclear reactor containment for containment of molten corium in severe nuclear reactor accidents are disclosed. Molten corium can be quickly cooled and solidified by the endothermic decomposition of the sacrificial material. |
| Use: System for delivering a carbonate-based material within a nuclear reactor containment |
| Advantage: The system ensures effective cooling and immobilization of the core melt, eliminates or minimizes hydrogen gas release, and maximizes radionuclide retention. |
| Novelty: System (10) has a nuclear reactor vessel (20) contained within the nuclear containment, a storage tank containing a mass of the carbonate-based material, and a gravity fluid delivery system for transporting the carbonate-based material within the nuclear containment vessel (30). |
