Abstract

A core-melt source reduction system for ending the progression of a molten core during a core-melt accident and resulting in a stable solid cool matrix. The system includes alternating layers of a core debris absorbing material and a barrier material. The core debris absorbing material serves to react with and absorb the molten core such that containment overpressurization and/or failure does not occur. The barrier material slows the progression of the molten core debris through the system such that the molten core has sufficient time to react with the core absorbing material. The system includes a provision for cooling the glass/molten core mass after the reaction such that a stable solid cool matrix results.

Core-Melt Source Reduction System (COMSORS) to terminate LWR core-melt accidents

Conference Forsberg, C W ; Beahm, E C ; Parker, G W

One of the design, safety, and licensing issues for the next generation of light-water reactors is this: What approach should be used to terminate a reactor core-melt accident and ensure no reactor containment failure in the unlikely event of an accident that results in core debris upon the containment floor? The safety concerns are that the debris will (1) melt through the concrete floor (thereby penetrating the containment) and (2) generate noncondensable/burnable gases (thus pressurizing the containment and threatening its integrity). Noncondensable gases include burnable hydrogen and carbon monoxide, generated primarily from the reaction of zirconium with concrete decomposition productsmore »« less

Termination of light-water reactor core-melt accidents with a chemical core catcher: the core-melt source reduction system (COMSORS)

Technical Report Forsberg, C W ; Parker, G W ; Rudolph, J C ; ...

The Core-Melt Source Reduction System (COMSORS) is a new approach to terminate light-water reactor core melt accidents and ensure containment integrity. A special dissolution glass is placed under the reactor vessel. If core debris is released onto the glass, the glass melts and the debris dissolves into the molten glass, thus creating a homogeneous molten glass. The molten glass, with dissolved core debris, spreads into a wide pool, distributing the heat for removal by radiation to the reactor cavity above or by transfer to water on top of the molten glass. Expected equilibrium glass temperatures are approximately 600 degrees C.more »« less
