Notes:
1.
Ingtially once per month until exposure hours (M as defined on Figure '4.1-1)' are 2.0 X 10 ;'tiiereafter, according to Figuref 4.1-1 with ~an interval not less than 1 month nor more than 3 months. The compilation of instrument failure rate data may include data

obtained from other boiling water reactors for whch the same design instrument operates in an environment similar to that of Quad Cities Units 1 and 2.
2.
Functional tests, calibrations, and instrument checks are not' required when these instruments are not required to be operable or tripped.
]
3.
This instrumentation is excepted from the functional test definition. The function test shall consist of injecting a simulated electric signal into the measurement channel.
4.
This instrument channel is excepted from the functional calibrated using simulated electrical signals once everytest definitions and shall be 3 months.
5.
Functional tests shall be performed before each startup with a required frequency not 'to exceed once per week.
Calibrations shall be performed during each startup or during controlled shutdowns with a required frequency not to exceed once per week.
j 6.
The positioning mechanism shall be calibrated every refueling outage.
7.
Logic system functional tests are performed as specified in the applicable section for these sytems.
i 8.
Functional tests shall include verification of operation of, the degraded voltage. 5 i
minute timer and 7 second inherent timer.
- 9.. Verification of the time delay setting of 3 st:' $ 10 seconds shall be performed during each refueling outage.
- 10. Trip units are functionally tested monthly.. A calibration of the. trip unit is to be performed concurrent with the functional testing. Transmitters are calibrated once per j
operating cycle.
