TABLE NOTATION

• With the control rod drive trip breakers in the closed position and the control rod drive system capable of rod withdrawal.

• • When Shutdown Bypass is actuated.

1. The provisions of Specification 3.0.4 are not applicable.

1. 1. High voltage to detector may be de-energized above 10-10 amps on both Intermediate Range channels.

(a) Trip may be manually bypassed when RCS pressure cl720 psig by actuating Shutdown Bypass provided that:

(1) The Nuclear Overpower Trip Setpoint la $5% of RATED THERMAL POWER, (2) The Shutdown Bypass RCS Pressure-High Trip Setpoint of 41720 psig is imposed, and (3) The Shtudown Bypass is removed when RCS pressure 71800 psig.

(b) Trip may be manually bypassed for a maximum of 15 minutes when reactor power is less than 40% to perform the following operations:

1) Switchover between Startup and Unit Auxiliary Transformers,

2) Energizing an idle Reactor Coolant Pump,

3) De-energizing an active Reactor Coolant Pump, or

4) Special Tests.

ACTION STATEMENT ACTION 1 -

With the number of channels OPERABLE one less than required by the Minimum Channels OPERABLE 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 be in at least HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and/or open the control rod drive trip breakers.

ACTION 2 - With the number of OPERABLE channels one less than the Total Number of Channels STARTUP and/or POWER OPERATION may proceed provided all of the following conditons are satisfied:

a. The inoperable channel is placed in the tripped condition within one hour.

b. The Minimum Channels OPERABLE requirement is met; however, one additional channel may be bypassed for up to 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> for surveillance testing per Specification 4.3.1.1.
