i op to SEISMIC INSTRtJMENTATION F.T. &C A. PlJRPOSF

1. To provide instrtictions for performing an instrument functiona) test and calibration on the seismic system instrumentation as required by Unit 2 Tech. Specs. Table 3,3,6.2-1 and Table 4.3.6.2-1.

2. This procedtire is applicable to instrument listed on Table 1.

NOTE Where required in initial equipment component position verifications, independent verification requires there will be a second person present to accomplish a physical verification and also to initial the steps on the Data Package, For accomplishment of maintenance and starveillance, verification is only required to be completed following accomplishnant of the procedure steps for each indi"idual eqttipment component.

B, FREGIJENCY

1. Monthly, as required by the manufacturer

2. Once/6 months C. RAFFTY Observe safety procedures outlined in Georgia Power Company, SAFETY, Gection "0".

NOTE Defore removing instrument from service, insure that one of the following instruments are operable:

(1) Free Field Accelerometer (2) Peak Response Spectrum Recorder (3) Peak Accelerograph D. REFERENCES

1. Inform the Shift Supervisor that the test is to be performed,

2. Insert key and turn switch to OFF,

3. Put on calibration record using the key switch- Turn the-p key to each position with a positive snap action, U a, Turn the key switch (clockwise) to TEST for 60 - c5 seconds.

h. Turn ihe key switch (clockwise) to CALIB and hold for 1-2 seconds,

c. Turn the key switch (clockwise) to NAT FREG and hold for 1-2 seconds.

d Turn the key switch (counter clockwise)-to CALIB and hold for 1-2 seconds,

e. Turn the key switch (counter clockwise) to TEST and

, hold for 10 - 15 seconds,

f. Turn the key switch (counter clockwise) to OFF, Wait 15 - 20 seconds for the time delay to reset.

g. Turn the key switch to OPERATE, Wait 60 - G5 seconds-before proceeding,

4. In the 230 KV switchyard remove the upper cover from the T Seismic Trigger and start the SMA-3 by gently blowing or, the vertical starter mass. Allow the system to record

[^;.

V background vibrations until it automatically stops (appnoxiately 10 seconds), Replace the upper cover, Return to.-the control panel H11-P701, The event indicator should be white,

5. Turn key switch to TEST and then back to DFF. This will reset the event indicator to black.- Wait 15-20 seconds for

the time deJay to reset before proceeding.

NOTE Independent verification of equxpment component position requires there will be two (2) individuals to perform the verifications with both initialling the steps on the Data Package.

G. Replace tape cassette with new cassette. (Independent Verification Required)

7. Repeat step E.3 to put calibration record on tape.

8. Turn the key switch to OPERATE and remove the key

9. Check to see that the event indicator is black.

(Independent Verification Required) p 10. Forward status check tape to I & C supervisor for mailing.

Q (Independent Verification Required)

11. Notify the Shift Supervisor that the test is complete.

F. CALIBRATION AND PERIODIC MAINTENANCE

' Refer to l(inemetric SMA-3 OAMP (Guality Assurance Maintenance Program) and to purchase order nimiber PEl+-9803 for the calibration and periodic maintenance to be performed by f(i nemetri c s. The calibration and maintenance will be performed per 1(inemetrics procedures, G. RESTORATION OF BEISMIC INSTRItMFNTATION AND DATA RETRIEVAL

1. RESTORATION OF SEISMIC INSTRUMENTATION a,

Wait until tape transports have stopped turning, or yellow ligh-t on Control Panel has gone off. Event indicator should be white.

b. Perform Calibration Procedure via key switch.

(1) Turn 1(ey switch to OFF, then to TEST. Walt 15 seconds, r

(5) Turn key-switch to TEST for 10 seconds.

(6) Turn key switch to CFF, then to OPERATE.

(7) Wait until tape-transports have stopped turning.

. Event indicator should be black.

c. Remove and label cassettes one at a time. Information on cassette should include.

-date of removal

-time of removal

-tape transport number (should already be labeled)

-name of individual performing sequance After removing each cassette from its respective tape transport, replace it with another cassette immediately, The new cassette should be labeled with the recorder model and serial number. (Independent

,3, Verification Required)

' ') d. After labeling all cassettes, and each tape transport has a new cassette, repeat Step G.1.b, i.e.,_run a calibration record on the new tapes. SMA-3 system is now ready to record.

a. Store all cassettes in one location, away from all objects (such as large magnets, etc.) which could affect 1he recorded data, free from excess temperatures and humidity,

2. RETRIEVAL OF SEISMIC OATA a, Complete section G.1

b. Rewind and play back all three channels from each cassette ' rom the beginning to the end of the data (indicated when time marker t. eases) using the SMP Playback System. This~is accomplished as follows:

(1) Insert first cassette in to tape transport. Make sure T-slide is all the way up.

(2) Turn POWER SELECT switch to AC RUN,

• NOTE:

-('}

U If AC power has been disconnected or is nnt operational, turn POWER SELECT switch tc GATTERY RUN.

(5) Turn STYLUS switch to ON, (G) Turn CHART DRIVE switch to 25 mm/sec and adjust POSITION and STYLUS HEAT controls, (7) Turn off CHART DRIVE.

(B) Turn TRANSPORT switch to ON, Wait until the " time marker" begins to tick, then turn CHART DRIVE ~to 25 mm/sec.

(9) After time marker ceases to tick, depress the STYLUS DRIVE - CAL switch upward for 2 seconds.

(10) Turn CHART DRIVE TO OFF, (11) Using T-slide on tape-transport, rewind the tape '

q to the beginning.

\j

(12) Rip-off chart paper, Label each record with-exactly the same data written on the cassette from which it was played back plus the channel selected.

(13) Turn CHANNEL SELECT switch to 2 and repeat Steps' (8) through (11),
