TABLE 15.4.1-1 (1 of 4)- ,

MINIMUM FREQUENCIES FOR CHECKS, CALIBRATIONS AND TEST OF INSTRUMENT CHANNELS No. Channel Description Check Calibrate Test Remarks

1. Nuclear Power Range S(1)** D(1)** B/W(2)** (1) Heat Balance M*(3)**(4) Q*(3)**(4) (2) Signal to AT; bistable action (permissive, rod stops, trips)

(3) Upper and lower chambers for axial off-set (4) Compare incore to excore axial flux difference. Recalibrate if the

absolute difference is greater than i or equal to 3 percent.

1 2. Nuclear Intermediate Range S(1)** N.A. P(2) (1) Once/ shift when in service

(2) Log level; bistable action j (permissive, rod stop, trips)

3. Nuclear Source Range S(1) N.A. P(2) (1) Once/ shift when in service (2) Bistable action (alarm, trips)

4. Reactor Coolant Temperature S R B/W(1)** (1) Overtemperature -AT (2) (2) Overpower - AT

! 5. Reactor Coolant Flow S** R M**(1) (1) Analog and single loop loss-of-flow

, logic testing.

R(2) (2) Logic channel testing for reactor i trip on loss of reactor coolant i flow in both loops shall be per-l formed each refueling interval.

l 6. Pressurizer Water Level S** R M**

i

] 7. Pressurizer Pressure S** R M**

i'

8. 4 KV Voltage N.A. R M** Reactor protection circuits only

9. Analog Rod Position S(1)** R M** (1) With step counters i

0 By means of the moveable incore detector system.

QQ Not required during periods of refueling shutdown, but must be performed prior to starting up if it has not been performed during the previous surveillance period. Tests of permissive and low

power trip bistable setpoints which cannot be done during power operations shall be conducted prior to startup if not done in the previous two weeks. 8704300127 870414 PDR ADOCK 05000266 P PDR
