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.Permissive/Interlock Channels Coincidence Setting Limit P-6 Intermediate Range Nuclear Instrument 1 of 2 > 10s% RATED POWER Power Range Nuclear Instrument 3 of 4 < 12.2% RATED POWER P-7 AND i Turbine Impulse Pressure 2 of 2 < 12.2% RATED POWER (a)P-8 !
