NOTES FOR TABLE 3.1.1 l
1.
There shall be two OPERABLE or tripped TRIP SYSTEMS for each function.
If the minimum number of OPERABLE INSTRUMENT CHANNELS for a TRIP SYSTEM cannot be met, the affected TRIP SYSTEM shall be placed in the safe (tripped) condition, or the appropriate actions listed below shall be taken.
i A.
Initiate insertion of OPERABLE rods and complete insertion of all OPERABLE rods l within four hours.
B.
Reduce power to less than 30% of RATED POWER.
l t
i C.
Reduce power level to IRN range and place Reactor Mode Selector Switch in the i
STARTUP position within eight hours and depressurize to less than 1000 psig.
1 D.-
Reduce turbine load and close Main Steam Isolation Valves within eight hours.
2.
Permissible to bypass, with control rod block, for Reactor Protection System reset in REFUEL and SHUTDOWN positions of the Reactor Mode Selector Switch.
3.
This note deleted.
4.
Permissible to bypass when turbine first stage pressure is less than 30% of full load.
5.
IRMs are bypassed when APRMs are onscale and the Reactor Mode Selector Switch is in the RUN position.
6.
The design permits closure of any two lines without a full scram being initiated.
7.
When the reactor is suberitical, fuel is in the vessel, and the reactor water temperature is less than 212*F, only the following trip functions need to be OPERABLE:
A.
Reactor Mode Selector Switch in SHUTDOWN.
B.
Manual scram.
C.
IRM high flux at 120/125 indicated scale.
D.
8.
Not required to be OPERABLE when PRIMARY CONTAINMENT INTEGRITY is not required.
9.
Not required to be OPERABLE while performing low power physics tests at atmospheric pressure during or after refueling at power levels not to exceed 5 MW(t).
- 10. Not required to be OPERABLE when the reactor pressure vessel head is not bolted to l the vessel.
