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.
Claims6
A system for delivering a carbonate-based material within a nuclear reactor containment, comprising:
- a light water or boiling water nuclear reactor contained within a primary nuclear containment;
- a storage tank containing a mass of the granular carbonate-based material external to the primary nuclear containment and within a secondary containment surrounding the primary containment;
- an injectable fluid delivery system for injecting the carbonate-based material under pressure through one or more carbonate delivery nozzles within the nuclear containment vessel;
- and
- wherein the fluid delivery system is a pressurized, active delivery system.
