are given in Table 3.2.H.

I. Alternate Shutdown Capability I. Alternate Shutdown Capability

1. The alternate shutdown instruments 1. Each monitoring instrumentation listed in Table 3.2.I-1 and controls channel of Table 3.2.I-l shall be listed in Table 3.2.I-2 shall be demonstrated operable by performing operable during reactor power operations the Instrument Check and Channel and when the reactor coolant temperature Calibration at the frequencies shown is above 212'F. on Table 4.2.I.

2. With less than the minimum equipment 2. Each isolation switch, power supply, specified in Table 3.2.I-1 and and control circuit for the 3.2.I-2 operable, restore the components listed in Table 3.2.I-2 inoperable equipment to operable status shall be demonstrated operable at within 30 days, or notify the NRC and least once per cycle by operating provide plans to restore alternate each actuated component from the shutdown capability.
