Inoperable (per Tech Spec 3.3.4.2) and/or one or more Turbine 1 control Valve slow closing is determined from Figure 2.2-1*

times the Kf factor determined from Figure 2.2-2.

11, during Unit coastdown, power operation exceeding the equilibrium power level is desired, than Figure 2.2-3 shall be used.
