High-Temperature Freeze and Leak-Resistant Advanced Molten Salt Valve – Final Project Report

Armijo, Kenneth M.; Overacker, Aaron; Madden, Dimitri A.; Burton, Patrick D.; Parish, Jeffrey; Nelson, Michael; Radman, Ivica; Kruizenga, Alan; Brumback, Kyle

The overall goal of this investigation was to develop an innovative high-temperature chloride molten salt flow control valve capable of operation up to 750 °C. The team developed an integrated active and passive thermal management system to ensure robust design for freeze-thaw cycles, with either a bellows-sealed configuration, a high-temperature stuffing box, or combination of the two. The STM system is unique in the industry.
