1 SOUTH TEXAS PROJECT 7.0 RECORDING OF CALIBRATION 7.1 Frequency of Calibration Checks and Re-Calforation 7.1.1 Initial calibration will be made on each probe prior to use.
Additional calibration checks will be made at the beginning and end of each magnetic tape or every A hours, whichever comes first.
1 7.1.2 Additional calibrations will be performed and recorded when changing test probe, extension cables, eddy current instrument, recording instrument.or any other parts of the examination system.
When possible, the standard will be recorded prior to changing any part of the examination system.
7.1.3 If undesirable variations are noted during the calibration check, the probe will be re-calibrated and all tubes examined since the last calibration will be re-examined.
Undesirable variations are variations in recorded eddy current data
(
that in the judgment of the data analyst could obscure reportable discontinuities or could cause misinterpretation of flaw depth or location.
Note:
'All calibration settings made in calibration section are i
for operator viewing only.
These calibration settings do not alter the recording information and are not critical to the examination. See data avaluation Paragraph 9.2.
8.0 EXAMINATION PROCEDURE 8.1 After the probe is calibrated it will be attached to the probe pusher. The j
scan will be performed during probe retraction. The scan speed will not exceed 50 feet per minute.
8.2 At the beginning of each examination tne following information will be recorded:
8.2.1 Name of owners.

BulqG3Cd - Tube I.D. is greater than the nominal I.D. - opposite of dent signal, a horuup.1 signal going to the right first.
Sometimes occurs at top of tube sheets 6M +0.0, TSC +0.0) recorded in differential mix channel.
Copper Dgan jCUD) - A deposit of copper usually originating from the secondary side of tne sta tem (i.e., condensers, feedwater heaters).
Characterized by the signal in the pime frequency looking similar to a discontinuity indication going down and to the right with the corresponding mix frequency going up and to the right.
If the copper deposit is only on the 0.D. of the tube it will usually mix
( > out.
If the copper deposit is in a discontinuity, it may not mix out and a discon-tinuity indication may go up first.
Recorded in low mix frequency differential.
Dent (DNT) - Tube I.D. smaller than nominal I.D., occurring at support plate inter-4 sections or top of tube sheets. Generally caused by magnetite build up in older l
Westinghouse and C.E. steam generators. Recorded in differential mix.
l Ding (DNG) - Similar to dent but in free-standing part of tube. Zither caused in manuf acturing or by mechanical cause. Recorded in prime frequency.
Dent With Possible Indication (DNI) - Possible discontinuity indication associated with dent but is not measurable. Recorded from differential mix.
j Distorted Roll Transition (DRT) - Self explanatory.
t Distorted Roll Transition With Possible Indication (DRI) - A distorted roll transi-tion that has sufficient distortion that a discontinuity may be creating the distor-tion.
Recorded in low mix frequency differential.
l Distorted Support Signal (DSS) - Support signal that has a residual mix indication that is not indicative of a defect signal or the signal is not of sufficient amplitude to be reported. Recorded in prime frequency or differential mix.
Distorted Support Signal W/ Indication (DSI) - Support signal that has a residual n ix indication with a non-quantifiable defect signal.
Recorded in prime frequency or differential mix.

1 SOUTH TEXAS PROJECT Distorted T'op Of Tube Sheet (DTS) - Generally refers to fully expanded tube sheets when the expansion or roll is not aligned properly.
Recorded in low mix frequency differential, the roll is measured in inches above or below the actual tube sheet signal.
Could also refer to the tube sheet signal in non-rolled tube sheet in the same manner as DSS.
Distorted Top Of Tubesheet W/ Indication (DTI) - Refers to top of tubesheet signal (fully expanded, fully rolled, or non-rolled tubesheets) with a non-quantifiable defect signal. Recorded in differentiel mix.
Expansion (EXP) - Used on preheater model steam generators where the tube has been expanded into the tube supports to prevent vibration.
Recorded in differential mix.
Expansion With Possible Indication (EPI) - In preheater model steam generators if a possible indication is present in the expansion.
Probably recorded in low mix fre-quency differential.
Expansion Transition Location (ETL) - Used for fully expanded tube sheets when the expansion is above the top of the tube sheet. Normally not reported until ETL is.3"
(
above top of tube sheet. Criterion for reporting will be determined on a job-by-job basis.
Fixture (FIX) - Used when tubes cannot be examined because the fixture foot is obstructing tube or the fixture will not reach a particular tubc.
ID Chatter (IDC) - Caused by manuf acturing process {pilgering). Characterized by long areas of horizontal motion.
Recorded in prime frequency.
Incomplete Test (INC) - Tube has not been run to the extent required or complete tube not recorded.

1 4.13 The track assembly must now be moved f ar enough from the divider plate to allow the upper track to tilt to its level position. The track position is adjusted af ter loosening the three set screws i
located on the track increment scale above the lights. The track should be placed so that it rests against the divider plate, and then backed off enough distance so the upper track can reach a level i
state.
This distance is about 6 increments.
Tighten the three set screws after track position is established. Make sure the green indicator light is still on. If not, than rotate manway mount until it comes on.
VOTE _: You may want to document the track position increment reading or future use.

4.14 Prior to installing the arm assembly, enter the CAL INSP mode in the software. Make sure that the arm has been folded up over the top of 4
the pole and is resting against the mechanical stop.
The arm assembly should be folded such that when you re-open the arm j (
from the pole, the arm moves towards the divider plate.
After you have checked these two conditions, then press the SET OFST soft key
~
in the shif ted mode. This will set an offset for the arm encoder and make a guess at an offset for the pole encoder so that the picture on your display closely approximates the respective l
positions of the arm and pole inside the bowl. The offset for the pole encoder will be recalculated at the end of the calibration.
4.15 Install the arm assembly on the track raiIs and insert it through the manway. Slide the arm assembly until it locks into place.
4.16 Install the manway clamp.
