TABLE 4.3-1 (Continued)

! TABLE NOTATION

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

(1) - If not performed in previous 7 days.

] (2) - Heat balance only, above 15% of RATED THERMAL POWER. Adjust channel if absolute difference greater than 2 percent.

(3) - Compare incore to excore axial flux difference every 31 EFPD.

Recalibrate if the absolute difference is greater than or equal to 3 percent.

(4) -

Manual ESF functional input check every 18 months.

(5) -

Each train or logic channel shall be tested at least every 62 days on a STAGGERED TEST BASIS.

(6) -

Neutron detectors may be-excluded from CHANNEL CALIBRATION.

(7) -

Below the P-6 (Block of Source Range Reactor Trip) setpoint.

(8) -

Logic only, if not performed in previous 92 days.

(9) -

CHANNEL FUNCTIONAL TEST will consist of verifying that each channel indicates a turbine trip prior to latching the turbine and indicates no turbine trip prior to P-9.

(10) - If not performed in the previous 31 days.

FARLEY-UNIT 1 3/4 3-14 AP2NDMENT NO.
