k 3/4.2 POWER DISTRIBUTION LIMITS LINEAR HEAT R ATE LIMITING CONDITION FOR OPERATION 3.2.1 The linear heat rate shall not exceed the limits shown on Figure 3.2-1.

APPLICABILITY: MODE 1.

ACTION:

During operating with the linear heat rate being monitored by the Incore Detector Monitoring System, comply with the following ACTION:

With the linear heat rate exceeding its limit, as indicated by four or more coincident incore channels, within 15 minutes initiate corrective action to reduce the linear heat rate to within the limits and either:

Restore the linear heat rate to within its limits within one hour, or a.

. b.

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 />.

During operation with the linear heat rate being monitored by the Excore Detector Monitoring System, comply with the following ACTIONS:

With the linear heat rate exceeding its limit, as indicated by the AXIAL SHAPE INDEX being outside of the power dependent limits on the Power Ratio Recorder and with the THERMAL POWER:-

Above 100% of the allowable power level determined by l

a.

Specification 4.2.1.2.c, within 15 minutes either restore the AXIAL SH APE INDEX to within the allowable limits as required per l

Technical Specification 3.2.2 or reduce THERM AL POWER to f 100% of the allowable' power level determined by Specification

~4.2.1.2.c.

b. - f,100% of the allowable power level determined by Specification l

4.2.1.2.c, either restore the AXIAL SHAPE INDEX to within the

{

al'owable limits as required per Technical Specification 3.2.2 within i isour from initially exceeding the linear heat rate limit or be in HOT STANDBY within the next 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.

SURVEILLANCE REQUIREMENTS 4.2.1.1 The linear heat rate shall be determined to be within its limits by continuously monitoring the core power distribution with either the excore detector monitoring system or with the incore detector monitoring system.
