Notes f:r Tablo 4.1-1 (Cont'd)
N f
d.
Calibrations are not required when the systems are not required to be operable or are tripped.
!Iowever, if calf brations are missed, they shall be performed prior to returning the system to n
an operable status.
4 This instrumentation is exempted from the instrument functional test definition. This instrument
~
e.
functional test will consist of injecting a simulated electrical signal into the measurement channels.
f.
Deleted 1
The water level in the reactor will be perturbed and the corresponding level indicator changes l
g.
will be monitored. This perturbation test will be perforacti every three months af ter completion of the fusctional test program.
h.
Physical luspection and actuation of these position switches will be performed once per operating cycle.
w 1.
Standard current source used which provides an instrument channel alignment. Calibration using a i
radiation source shall be made once per operating cycle.
J.
Measure time interval f rom EllC pressure switch actuation to RPS relay K14 de-energiration.
l k.
The electrohydraulic control oil pressure sensors shall be set to trip at >600 psig control oil pressure.
1.
Perform within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of start-up if not performed within the previous seven days.
When changing f rom the Run made to the Start and flot Standby Mode, perform the required m.
surveillance within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> af ter entering the Start and Ilot Standby mode unless performed within the previous seven days.
n.
The APRM, IRM and SRM channels shall be compared for overlap during each startup, if not performed within the previoun 7 days.
This calibration shall consist of the adjustment of the APRM channel to conform to the power p.
values calculated by a heat balance during the Run mode when thermal power > 25% of rated thermal power. Adjust the APRM channel if the absolute difference > 2%.
q.
This calibration shall consist of the adjustment of the APRM flow referenced simulated thermal power channel to conform to a calibrated flow signal.
