FQ (z)< ' RTP

K(z) for P

0.5, and 0.5 Where FQRTP = the FQ limit at RATED THERMAL POWER (RTP) specified in the CORE OPERATING LIMITS REPORT (COLR),

P = THERMAL POWER , and RATED THERMAL POWER K(z) = the normalized FQ(z) as a function of core height as specified in the COLR.

APPLICABILITY: MODE 1 ACTION:

With FQ(Z) exceeding its limit:

a. Reduce THERMAL POWER at least 1% for each 1% FQ(Z) exceeds the limit within 15 minutes and similarly reduce the Power Range Neutron Flux-High Trip Setpoints within the next 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months ; POWER OPERATION may proceed for up to a total of 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months ; subsequent POWER OPERATION may proceed provided the Overpower delta T Trip Setpoints have been reduced at least 1% for each 1% FQ(Z) exceeds the limit. The Overpower delta T Trip Setpoint reduction shall be performed with the reactor in at least HOT STANDBY.

b. Identify and correct the cause of the out of limit condition prior to increasing THERMAL POWER above the reduced limit required by a.

above; THERMAL POWER may then be increased provided FQCZ) is demonstrated through a core power distribution measurement to be within its limit.
