OSTI ID:2293706

Wang, Yifeng; Louie, David; Rao, Rekha R.; Templeton, Jeremy A.

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.
