PASSIVE COOLING SYSTEM FOR LIQUID METAL COOLED NUCLEAR REACTORS WITH BACKUP COOLANT FLOW PATH

摘要

24BR-05235 A liquid metal cooled nuclear fission reactor plant having a passive auxiliary safety cooling system for removing residual heat resulting from fuel decay during reactor shutdown, or heat produced during a mishap. This reactor plant is enhanced by a backup or secondary passive safety cooling system which augments the primary passive auxiliary cooling system when in operation, and replaces the primary system when rendered inoperable.
