Which inefficiency rises during rapid steam turbine start-up?

A)Increased condensation shock probability
B)Reduced blade fatigue tolerance
C)Elevated generator eddy current losses
D)Lower superheater tube creep rupture

💡 Explanation

Condensation increases because rapid heating hinders uniform thermal expansion, therefore more liquid accumulates than designed, leading to condensation shock formation, rather than gradual vaporization under consistent operational tempo.
