TABLE NOTATION

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

• • The channel (s) associated with the protective functions derived from the out of. service Reactor Coolant Loop shall be placed in the trip-ped condition.

1. The provisions of Specification 3.0.4 are not applicable.

1. 1. When below the P-6 setpoint.

1. 1. 1. When below the P-10 setpoint.

• When above the P-7 setpoint.

(1) The applicable MODES and. ACTION statement for these channels.noted in Table 3.3-3 are more restrictive and, therefore, applicable.

ACTION STATEMENTS ACTION 1 - With the number of channels OPERABLE one less tLan the Mini-mum Channels OPERABLE requirement, be in at least HOT STANDBY within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.

provided the other channel is OPERABLE.

ACTION 2 With the number of OPERABLE channels one less than the Total Number of Channels, STARTUP and/or POWER OPERATION may pro-ceed provided all of 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 />.

b.

The Minimum Channels OPERABLE requirement is met; how-ever, 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.

c.

Either THERMAL POWER is restricted to $75% of RATED THERMAL POWER and the Power Range Neutron Flux trip setpoint is reduced to $85% of RATED THERMAL POWER within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />; or, the QUADRANT POWER TILT RATIO is monitored at least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />, per Specification 4.2.4.c.

ACTION 3 - With the number of channels OPERABLE one less than the Minimum Channels OPERABLE requirement and with the THERMAL POWER level:

a.

Below P-6, restore the inoperable channel to OPERABLE status prior to. increasing THERMAL POWER above the P-6 setpoint.

b.

Above P-6, operation may continue, provided that THERMAL POWtR is expeditiously placed within the range of the Source Range or Power Range Instrumentation.

ACTION 4 - With the number of OPERABLE channels one less than the Mini-mum Channels OPERABLE requirement, suspend all operations involving positive reactivity changes.

ACTION 5 - With the number of channels OPERABLE one less than the Mini-mum Channels OPERABLE requirement, verify compliance with the SHUTDOWN MARGIN requirements of Specification 3.1.1.1 within.

ACTION 6 - With the number of OPERABLE ch'nnels one less than the Total a

Number of Channels, STARTUP and/or POWER OPERATION may pro-ceed provided both of 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 />.

b.- The Minimum Channels OPERABLE requirement is met; how-ever, 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.

l ACTION 7 -' With the number of OPERABLE channels less than the Total l

Number of Channels, place the inoperable channel in the l

tripped condition within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.

Operation may continue until performance of the next required CHANNEL FUNCTIONAL TEST.

ACTION 8 - With a channel associated with an operating loop inoperable, l

restore the inoperable channel to OPERABLE status within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 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 />.
