Which risk appears when a steam turbine undergoes rapid cooling?

💡 Explanation

Rapid cooling generates thermal gradients, so thermal stress crack propagation rises due to differential contraction. The differential contraction applies stress beyond the material’s yield strength causing sudden/brittle fracture. Therefore, 'A' is the predicted outcome, rather than increased hammer effect or an improvement in efficiency.
