Fission-Product Scrubbing in Ice Compartments

摘要

Some nuclear power reactors have an ice-condenser system designed to suppress the increase in pressure within containment that would otherwise result from a ruptured coolant system. This condenser system also has the inherent ability to remove fission products from the gas flow associated with such highly improbable, severe accident conditions. The extent to which fission product aerosols and gases are removed (scrubbed) from this flow has been predicted from first-principle models and found to be significant. (ERA citation 08:051326)
