Radiation Monitors Notes:

(1) There shall be two operable or tripped Trip Systems for each function. An Instrument 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 performance of required surveillances without placing the Trip System in the tripped condition provided that at least one other OPERABLE Channel in the same Trip System is monitoring that parameter.

(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 Instrument Channel per Trip System inoperable:

1) For Functions 1 or 2, 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 />

2) For Functions 3 or 4, place the inoperable Channel in a downscale trip condition, or place the Trip System in the tripped condition within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />

--OR--

3.2/4.2 59 Amendment No. 10, 71, 91, 103, 128, 140

Notes: (cont'd)

(b) With more than one Instrument Channel per Trip System inoperable:

1) For Functions 1 or 2, immediately satisfy the requirements by placing the appropriate Channels or Trip Systems in the tripped condition,

2) For Functions 3 or 4, immediately proceed to Note 2c

--OR --

(c) If (a) or (b) cannot be met, then place the plant under the specified required conditions using normal operating procedures.

(3) Need not be operable when primary containment integrity is not required.

• Required Conditions when minimum conditions for operation are not satisfied.

A. The reactor building ventilation system isolated and the standby gas treatment system operating.

B. Establish conditions where secondary containment is not required.
