Design Criteria and Candidate Concept for High-Performance Cold Trap

摘要

High performance criteria are outlined for cold traps for LMFBRs and other sodium systems. A cold trap is designed in which the temperature of the incoming sodium is reduced only after it is well within the crystallizer. As the impurities buildup continues to the point where the stage 1 downcomer flow would be impeded, the incoming flow and cooling circuits are switched to stage 2. The sodium in the crystallizer could be stirred by electromagnetic or mechanical means. 2 figures. (ERA citation 81:025491)
