NOTE 1:

(Continued)

.For Unit 2 (I) for q, - q, between -65% and +2-54 27(5% f (a q) = 0, where q, and q, t

are percent RATED THERMAL POWER in the top and bottom halves of the core respectively, and qt + q, is total THERMAL POWER in percent of RATED THERMAL POWER.

I (ii) for each percent that the magnitude of qt - q, exceeds -65%. the N-16 Trip Setpoint shall be automatically reduced by 864.0;0** of its value at RATED THERMAL' POWER, and I

(iii) for each percent that the magnitude of qt - q, exceeds +2-5417;54.

the N-16 Trip Setpoint shall be automatically reduced by 1-654 2;p01 of its value at RATED THERMAL POWER.
