Which outcome occurs when cryogenic pump bearings experience partial coolant blockage during liquid helium transfer?

💡 Explanation

When coolant blockage occurs, heat transfer decreases because conduction pathways drastically reduce in effectiveness, leading to localized heating and potential bearing seizure induced by thermal expansion. Therefore, bearing seizure results, rather than efficiency gains, reduced cavitation which require full coolant saturation, or vibration damping which would depend on entirely different mechanism.
