Protection System Channels. Eagle 21 Version". Revision 1. April 1992 for Westinghouse source range and Intermediate range neutron flux channels. for channels other than the Westinghouse source and intermediate range neutron flux channels, setpoints are i estabitshed tolerances for instrument channel and setpoint errors as specified in " Zion N555 Setpoint Evaluation, Protection System Channels. Eagle 21 Version", Revision 2, March 1993. The Instruments shall not be set to exceed a Limiting Safety System Setting.
+* For channel test, calibration er maintenance, the minleve noudier of OPERA 8tE channels may be reduced by one but to not less than one, and the minimum degree of redundancy may be reduced by one but to not less than zero, for a maximum of two hours. For Automatic Reactor Trly Logic and Reactor Trip Breakers, the allowable outage time is a maximue of eight hears.
W en block conditions exist, maintain normal operation.
' Maintain Het Shutdown' means maintain or proceed to Het shutdown within fevr hours if the waacceptable condillon arises during power operation.
Verify shutdown margin immediately and comply with Section 3.2.1.A,5.

- During Modes 3, 4 er 5 and with the Reactor Trip system breakers closed and the Centrol Rod Drive System capable of red withdrawal, the following applies: With the number of OPERABLE channels one less than the Minimum OPERA 8LE Channels requirement, restore the Inoperable channel to OPERABLE status within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> or open the Reactor trip breakers within the next hour.

The breaker sha11 not be bypassed while one of the diverse trip features is inoperable except for the time required for performing maintenance and testing to restore the breaker to OPERA 8tE statws.
