TABLE NOTATION
- Trip function may be blocked in this MODE below the P-1 1 (Pressurizer Pressure Interlock) setpoint.
Trip function may be blocked in this MODE below the P-12 (Low-Low Tavg Interlock) setpoint.
Except when below P-12 with all MSIVs and bypasses closed and disabled.
The provisions of Specification 3.0.4 are not applicable.
