2,300-Hour Rare Experiment Confirms Graphite Seals Can Withstand Molten Salt Reactor Conditions
A University of Michigan research team has completed a rare 2,300-hour experiment testing commercial shaft seals under simulated molten salt reactor (MSR) conditions. Results showed that graphite sleeve seals exhibited no significant corrosion or degradation when exposed to FLiNaK molten salt, high temperatures, and 1,500 RPM shaft speeds. Argon was identified as the optimal cover gas, providing critical engineering data for next-generation reactor design.
