O ACTION 3
- With the number of channels OPERABLE one less than the Minimum Channels OPERABLE requirement and with the THERMAL POWER level:
a.
Below the P-6 (Intermediate Range Neutron Flux Interlock)
Setpoint, restore the inoperable channel to OPERABLE status prior to increasing THERMAL POWER above the P-6 '
- Setpoint, b.
Above the P-6 (Intermediate Range Neutron Flux Interlock)
Setpoint but below 10% of RATED THERMAL POWER, restore the inoperable channel to OPERABLE status prior to increasing j
THERMAL POWER above 10% of RATED THERMAL' POWER.
i ACTION 4
- With the number of OPERABLE channels one less than the Minimum Channels OPERABLE requirement, suspend all operations involving i
positive reactivity changes.
ACTION 5.1 - With the number of OPERABLE channels one less than 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 within the next hour open the reactor trip breakers and suspend all operations involving positive reactivity changes. With no channels OPERABLE
.l complete the above actions within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.
ACTION 5.2* - With the number of OPERABLE channels one less'than the Minimum
.j 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 within the next hour verify either valve CS-8455 or valves CS-8560, FCV-1118, CS-8439, CS-8441, and CS-8453 are closed and secured in position, and verify this position at least once per 14 days thereafter.
With no channels OPERABLE, complete the above actions within 4-hours and verify the positions of the above valves at least once per 14 days thereafter.
ACTION 6
- With the number of OPERABLE channels one less than the Total Number of Channels, STARTUP and/or POWER OPERATION may proceed provided the following conditions are satisfied:
a.
The inoperable channel is placed in the. tripped condition within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, and b.
The Minimum Channels OPERABLE requirement is met; however, the inoperable channel may be bypassed for up to 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> for surveillance testing of other channels per Specification 4.3.1.1.
ACTION 7
- With less than the Minimum Number of Channels OPERABLE, within I hour determine by observation of the associated permissive annunciator window (s) that the interlock is in its required state for the existing plant condition, or apply Specification 3.0.3.
- Boron Dilution Flux Doubling requirements become effective for Unit I and Unit 2 after criticality for Unit 1, Cycle 4.
