L Table 3.2.1 (Continued)
NOTES:
(1)
There shall be two operable or tripped trip systems for each function. A channel (a shared channel is considered one channel) may l be placed in an inoperable status for up to 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> for required surveillance without placing the trip system in the tripped condition provided that at least one other operable channel in the same trip system is morntonng that parameter.
i (2)
Upon discovery that minimum requirements for the number of operable or operating trip systems or instrument channels are not satisfied action shall be initiated as follows:
[
(a) With one required instrument die mel inoperable in one or more trip functions, place the inoperable channel (s) or trip system in the tripped condition within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />, or (b) With more than one instrument channel inoperable for one or more trip functions, immediately satisfy the requirements by
[
placmg appropnate channels or systems in the tripped condition, or (c) Place the plant under the specd required conditions usmg normal operating procedures.
f (3)
Low pressure in main steam line only need to be available ir:it.e RUN position.
(4)
All instrument channels are shared by both trip systerr.s.
(5)
May be bypassed when necessary only by closing the manual containment isolation valves during purging for containment inerting or de-inerting. Venfication of the bypass condition shall be noted in the control room log. Also, need not be operable when primary containment integrity is not requwed.
i i
Required conditions when minimum conditions for operation are not satisfied.
A.
Group 1 isolation valves closed.
B.
Reactor Power on IRM range or below and reactor in startup, refuel, or shutdown mode.
+
C.
Isolation Valves closed for: Shutdown Cooling System, and Reactor Head Cooling Line.
l D.
Comply with Condition C. above.
E.
Isolation Valves closed for: Reactor Cleanup System.
F.
HPCI steam line isolated. (See specification 3.5 for additional requirements.)
G.
RCIC steam line isolated.

(5)
Upon d;secc f that minimum requwements for the number of operable or W trip systems or h h a not satisfied schon shall be initiated as follows:
(a) With one required instrument channel inoperable per trip function, place the inoperable channel or trip system in the tripped condition within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />, or (b) With more than one instrument channel per trip system inoperable, immediately satisfy the requirements by placmg appropriate channels or systems in the tripped condition, or (c) Place the plant under the specdied requwed condebons using normal operatmg procedures.

A channel may be placed in an inoperable status for up to 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> for required surveillance without placing the trip. system in the tnpped condition provided that at least one other OPERABLE channel in the same trip system is monitonng that parameter.
Required Cendihons when minimum conditions for operation are not satisfied.
A.
The reactor buildmg ventilation system isolated and the standby gas treatment system operating.
l B.
Establish condshons where secondary containment is not required.
