6. Reactor Trip Interlocks Protective instru mentation-settings for-reactor-trip-interlocks-shall -be-as follows: -

A. Prior to exceeding 12.2% of RATED POWER, the low pressurizer pressure trip, high pressurizer level trip, the low reactor coolant flow trips (for both loops), and the turbine trip-reactor trip are made functional.

B. Prior to exceeding 10% of RATED POWER, the single loop loss-of-flow trip is made functional.

7. Other Trips A. Undervoltage > 75% of normal voltage B. Turbine trip C. Manual trip D. Safety injection trip (Refer to Table TS 3.5-1 for trip settings)

Amendment No. 195 TS 2.3-4

TABLE TS 3.5-2 INSTRUMENT OPERATION CONDITIONS FOR REACTOR TRIP NOTES (1) One additional channel may be taken out of service for zero power physics testing.

(2) Deleted (3) When a block condition exists, maintain normal operation.

(4) Underfrequency on the 4-kV buses trips the Reactor Coolant Pump breakers, which in turn trips the reactor when power is above P-7.
