Deleted

3.

Functional tests are not required when the systems are not required to be operable or are tripped.

If tests are missed, they shall be performed prior to returning the systems to an operable status.

4.

This instrumentation is exempted from the instrument channel test definition. This instrument channel functional test will consist of injecting a simulated electrical signal into the measurement channels.

5.

Test RPS channel after maintenance.

NOTES FOR TABLE 4.1.2

1.

Adjust the flow bias trip reference, as necessary, to conform to a calibrated flow signal.

2.

Calibration tests are not required when the systems are not required to be operable or are tripped.

3.

Deleted.

4.

Maximum frequency required is once per week.

5..

Response time is not a part of the routine instrument channel test, but will be checked once per operating cycle.

6.

Physical inspection and actuation of these position switches will be performed during the refueling outages.

7.

Calibration of these devices will be performed during refueling outages.

To verify transmitter output, a daily instrument check will be performed. Calibration of the associated analog trip units will be performed concurrent with functional testing as specified in Table 4.1.1.

NOTES FOR TABLES 4.2.A THROUGH 4.2.G

1.

Initially once per month until exposure hours (M as defined on Figure 4.2-1) is 2.0 x 105; thereafter, according to Figure 4.2-1 with an interval not less than one month nor more than three months.

2.

Calibrations of IRMs and SRMs shall be performed during each startup or during controlled shutdowns with a required frequency not to exceed once per week.

3.

Deleted.

4.

Simulated automatic actuation shall be performed once each operating cycle. Where possible, all logic system functional tests will be performed using the test jacks.

5.

Reactor low water level and high drywell pressure are not included on Table 4.2.A since they are tested on Tables 4.1.1 and 4.1.2.

6.

The logic system functional tests shall include a calibration of time delay relays and timers necessary for proper functioning of the trip systems.

7.

Calibration of analog trip units will be performed concurrent with functional testing.

The functional test will consist of injecting a simulated electrical signal into the measurement channel. Calibration of associated analog transmitters will be performed each refueling outage.
