Which risk increases substantially during rapid isochoric water-to-steam phase transition in a closed autoclave?

A)Pressure vessel stress amplification✓

B)Condensation-induced thermal gradients

C)Exothermic reaction runaway effects

D)System-wide corrosion product formation

💡 Explanation

The risk of pressure vessel stress is increased because a rapid phase transition induces significant pressure rise within the closed system due to the increased volume of steam—a process called volumetric expansion. Therefore, high pressure may exceed design limits, rather than slower temperature changes provoking corrosion.
