When Shutdown Bypass is actuated.
The provisions of Specification 3.0.4 are not applicable.
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:
The inoperable channel is placed in the tripped condition within one a.
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.
