INSTRtNENTATION 3/4.3.9 FEEDWATER/ MAIN TURBIE TRIP SYSTEM ACTUATION INSTRUPENTATION LIMITIPC C0f0ITION FOR OPERATION l

3.3.9 - The feedwater/ main turbine trip system actuation instrunentation j channels shown in Table 3.3.9-1 shall be OPERABLE with their trip setpoints i set consistent' with the values shown in the Trip Setpoint column of Table 3.3.9-2.

APPLICABILITY:. Condition 1, when THERMAL POWER 2 25% RATED THERMAL POWER ACTION:

With a feedwater/ main turbine trip system actuation instrumentation channel trip setpoint less conservative than the value shown in the Allowable Values column of Table 3.3.9-2, declare the channel inoperable and either place the

, inoperable channel in the tripped condition until the channel is restored to OPERABLE status with its trip setpoint adjusted consistent with the Trip

/

Setpoint value, or declare the associated system inoperable.

a. With the number -of OPERABLE channels one less than required by the Minimum CPERABLE Channels requirement, restore the inoperable channel to OPERABLE status within 7 days or reduce thermal power

<,25% Rated thermal power within the next 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.

'b. With the number of OPERABLE channels two less than required .by the Minimum OPERA &.E Channels per Trip System requirement, restore at least one of the inoperable channels to OPERABLE status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or reduce thermal power < 25% rated thermal power within the next 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />'.

PLANT SYSTEMS 3/4.7.9 MAIN TURBIE BYPASS SYSTEM LIMITING CONDITION FOR OPERATION 3.7.9 The main turbine bypass system shall be OPERABLE.

APPLICABILITY: CONDITION 1,whenTHERMALPOWER225%RATEDTHERMALPOWER ACTION: With the main turbine bypass system inoperable, restore the system 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 determine MCPR to be equal to or greater than the MCPR limit in Specifications 3.2.3 'within one hour or take the ACTION required by that Specification.

SURVEILLATE REQUIREENTS

, 4.7.9 The main turbine bypass system shall be demonstrated OPERABLE at least once per:

a. 7 days by cycling each turbine bypass valve through at least one complete cycle of full travel, and

b. 18 months by:

1. Performing a system functional test which includes simulated automatic actuation and verifying that each automatic valve actuates to its correct position.

2. Demonstrating TURBINE BYPASS SYSTEM RESPONSE TIE to be less than or equal to 0.30 seconds.
