Which outcome occurs when cryogenic pump seals in liquid hydrogen transfer experience rapid disengagement?

A)Icing of external pump components
B)Detonation from rapid hydrogen combustion
C)Polymer degradation from radiation exposure
D)Seizure due to thermal contraction

💡 Explanation

When seals rapidly disengage, gaseous hydrogen leaks and mixes quickly with atmospheric oxygen, resulting in detonation due to rapid, unconfined combustion via the highly exothermic reaction. Therefore, detonation will results, rather than icing, degradation, or seizure, each requiring distinct pre existing conditions.
