STEAM GENERATOR "A" 9TH REFUELING FALL 1993 OUTAGE NORTH ANNA 2 l | |||
In Steam Generator "A," 3098 tubes were inspected full length with bobbin probes. | |||
One hundred and two, row 2 and row 3 tubes were examined in the U-bend region ; | |||
(tube support 7H to 7C) with Rotating Pancake Coil (RPC) probes. The remaining j portions of the row 2 and row 3 tubes were examined with bobbin probes. RPC ! | |||
examination was performed on 3199 tubes in the hot leg transition region at the top of ) | |||
the tubesheet. Supplemental examinations were also performed using RPC probes where additional confirmatory or other data was desired. A total of 122 tubes were plugged in this steam generator. Ninety-five tubes were plugged because of indications,14 tubes were plugged to " box" adjacent tubes which could not be stabilized (these tubes have sentinel plugs on the cold end), and 13 tubes were plugged as a precautionary measure (although the analysis process determined that these tubes do not contain flaw indications, concerns were noted with the signals in l these 13 tubes). Eleven of the plugged tubes required stabilization. See the attached I list and tube sheet maps for details. Please note that the number of indications displayed on the maps and delineated in the attached list will exceed the total number of plugged tubes, because several tubes contain more than one indication. | |||

@= Plugged As A Precauticnary Measure - These tubes contained a signal judged by the analysis program not to be an indication. However, due to the extent of the signal's vertical component and its location in the steam generator, the tube was plugged.

i STEAM GENERATOR "B" l 9TH REFUELING FALL 1993 OUTAGE NORTH ANNA 2 In Steam Generator "B," 3151 tubes were inspected full length with bobbin probes. | |||
i Eighty-nine row 2 tubes were examined in the U-bend region (tube support 7H to 7C) with Rotating Pancake Coil (RPC) probes. Eighty-eight of the row 2 tubes were examined in the non-U-bend area with bobbin probes (the remaining row 2 tubes were examined fulllength with bobbin probes). RPC examination was also performed l | |||
on 3239 tubes in the hot leg transition region at the top of the tubesheet. | |||
l Supplemental examinations were also performed using RPC probes where additional l confirmatory or other data was desired. A total of 89 tubes were plugged in this steam l generator. Sixty-nine tubes were plugged because of indications,16 tubes were plugged to " box" adjacent tubes which could not be stabilized (these tubes have sentinel plugs on the cold end), 3 tubes were plugged as a precautionary measure (although the analysis process determined that these tubes do not contain flaw indications, concerns were noted with the signals in these 3 tubes), and 1 tube was ! | |||
plugged in error. Three of the plugged tubes required stabilization. See the attached ! | |||
i list and tube sheet maps for details. Please note that the number of indications i displayed on the maps and delineated in the attached list will exceed the total number ) | |||
of plugged tubes, because several tubes contain more than one indication. | |||

9TH REFUELING FALL 1993 OUTAGE l NORTH ANNA 2 l | |||
In Steam Generator "C",2938 tubes were inspected full length with bobbin probes. | |||
Seventy-six row 2 tubes were examined in the U-bend region (tube support 7H to 7C) with Rotating Pancake Coil (RPC) probes. The remaining portions of the row 2 tubes were examined with bobbin probes. RPC examination was performed on 3014 tubes in the hot leg region at the top of the tubesheet. Supplemental examinations were also performed using RPC probes where additional confirmatory or other data was desired. A total of 409 tubes were plugged in this steam generator. Three-hundred and fifteen tubes were plugged for indications, 40 tubes were plugged to " box" adjacent plugged tubes that could not be stabilized (these tubes have sentinel plugs on the cold end), and 54 additional tubes were plugged as a precautionary measure (although the analysis process determined that these tubes do not contain flaw indications, concerns were noted with the signals in these 54 tubes). Seventeen of the plugged tubes required stabilization. See the attached list and tube sheet maps for-details. Please note that the number of indications displayed on the maps and delineated in the attached list will exceed the total number of plugged tubes, because several tubes contain more than one indication. | |||

{{#Wiki_filter:. , 1 l STEAM GENERATOR "A" 9TH REFUELING FALL 1993 OUTAGE NORTH ANNA 2 l In Steam Generator "A," 3098 tubes were inspected full length with bobbin probes. One hundred and two, row 2 and row 3 tubes were examined in the U-bend region ; (tube support 7H to 7C) with Rotating Pancake Coil (RPC) probes. The remaining j portions of the row 2 and row 3 tubes were examined with bobbin probes. RPC ! examination was performed on 3199 tubes in the hot leg transition region at the top of ) the tubesheet. Supplemental examinations were also performed using RPC probes where additional confirmatory or other data was desired. A total of 122 tubes were plugged in this steam generator. Ninety-five tubes were plugged because of indications,14 tubes were plugged to " box" adjacent tubes which could not be stabilized (these tubes have sentinel plugs on the cold end), and 13 tubes were plugged as a precautionary measure (although the analysis process determined that these tubes do not contain flaw indications, concerns were noted with the signals in l these 13 tubes). Eleven of the plugged tubes required stabilization. See the attached I list and tube sheet maps for details. Please note that the number of indications displayed on the maps and delineated in the attached list will exceed the total number of plugged tubes, because several tubes contain more than one indication. l I

= Tube Plugged and Stabilized. = Tubes Preventively Plugged To " Box" Adjacent Tubes Which Could Not Be Stabilized.
@= Plugged As A Precauticnary Measure - These tubes contained a signal judged by the analysis program not to be an indication. However, due to the extent of the signal's vertical component and its location in the steam generator, the tube was plugged. Also included are a number of tubes which the Virginia Power Eddy Curent Level lli requested to be plugged even though the normal analysis process considered the signal not to be a pluggable indication. TOTAL TUBES PLUGGED = 122 20
r l i STEAM GENERATOR "B" l 9TH REFUELING FALL 1993 OUTAGE NORTH ANNA 2 In Steam Generator "B," 3151 tubes were inspected full length with bobbin probes. i Eighty-nine row 2 tubes were examined in the U-bend region (tube support 7H to 7C) with Rotating Pancake Coil (RPC) probes. Eighty-eight of the row 2 tubes were examined in the non-U-bend area with bobbin probes (the remaining row 2 tubes were examined fulllength with bobbin probes). RPC examination was also performed l on 3239 tubes in the hot leg transition region at the top of the tubesheet. l Supplemental examinations were also performed using RPC probes where additional l confirmatory or other data was desired. A total of 89 tubes were plugged in this steam l generator. Sixty-nine tubes were plugged because of indications,16 tubes were plugged to " box" adjacent tubes which could not be stabilized (these tubes have sentinel plugs on the cold end), 3 tubes were plugged as a precautionary measure (although the analysis process determined that these tubes do not contain flaw indications, concerns were noted with the signals in these 3 tubes), and 1 tube was ! plugged in error. Three of the plugged tubes required stabilization. See the attached ! i list and tube sheet maps for details. Please note that the number of indications i displayed on the maps and delineated in the attached list will exceed the total number ) of plugged tubes, because several tubes contain more than one indication. l l l l l

= Tubes Plugged and Stabilized. = Tubes Preventively Plugged to " Box" Adjacent Tubes Which Could Not Be Stabilized. = Plugged in Error. l @ = Plugged as a precautionary measure. These tubes contained a signal judged by the analysis program not to be an indication. However, due to the extent of the signal's vertical component and its location in the steam generator, the tube was plugged.
TOTAL TUBES PLUGGED = 89 l l 20
l STEAM GENERATOR "C " ! 9TH REFUELING FALL 1993 OUTAGE l NORTH ANNA 2 l In Steam Generator "C",2938 tubes were inspected full length with bobbin probes. Seventy-six row 2 tubes were examined in the U-bend region (tube support 7H to 7C) with Rotating Pancake Coil (RPC) probes. The remaining portions of the row 2 tubes were examined with bobbin probes. RPC examination was performed on 3014 tubes in the hot leg region at the top of the tubesheet. Supplemental examinations were also performed using RPC probes where additional confirmatory or other data was desired. A total of 409 tubes were plugged in this steam generator. Three-hundred and fifteen tubes were plugged for indications, 40 tubes were plugged to " box" adjacent plugged tubes that could not be stabilized (these tubes have sentinel plugs on the cold end), and 54 additional tubes were plugged as a precautionary measure (although the analysis process determined that these tubes do not contain flaw indications, concerns were noted with the signals in these 54 tubes). Seventeen of the plugged tubes required stabilization. See the attached list and tube sheet maps for-details. Please note that the number of indications displayed on the maps and delineated in the attached list will exceed the total number of plugged tubes, because several tubes contain more than one indication. 1 l I l

= Tubes Stabilized and Plugged.
= Tubes Preventively Plugged To " Box" Adjacent Tubes Which Could Not Be Stabilized.
@= Plugged As A Precautionary Measure - These tubes contained a signal judged by the analysis program not to be an indication. However, due to the extent of the signal's vertical component and its location in the steam generator, the tube was plugged. Also included are a number of tubes which the Virginia Power Eddy Current Level lli requested to be plugged even though the normal analysis process c.onsidered the signal not to be a pluggable indication.
#= This tube was erroneously recorded on the indication map as containing a I through-wall indication of 40 - 49% instead of the correct category of 50 - 59%.

#C (# = number) of Support Plate in the Cold leg (e.g.,3C,6C, or 7C).
DEP Deposit. Signal rotates out of the flaw plane like a deposit. DI Distorted indication. A possible tube wall loss condition that is not quantifiable with a numeric percent call due to the existing signal characteristics. DIN Distorted Indication Not Confirmed. A possible tube wall loss condition that is not quantifiable with a numeric percent call due to the existing signal characteristics which was tested by the Rotating Pancake Coil (RPC) probe and was not confirmed.
#H (# = number) of Support Plate in the Hot leg (e.g.,3H,6H, or 7H).
INF Indication Not Found. Indicates that a previously reported indication, from current inspection data or historical data, is not found in the data being analyzed. This is also used to address the case where a tube / signal is being retested for positive identification (PID) and the retest data does not show any signal present. INR Indication Not Reportable. Indicates that a very small tube wall loss condition exists in the data being analyzed that is below the reportable criteria threshold for this specific inspection. This can be used to address indications called in previous inspections that are still detectable but fall below current criteria MAI Multiple Axial Indication. Describes multiple axially oriented indications from RPC Probe data MCI Multiple Circumferential Indication. Describes multiplo circumferentially oriented indications from RPC Probe data NOI Non Quantifiable Indication (retest). Used in lieu of a % thru wall value on a signal located in free span area of the tube which the analyst believes to be an indication but too distorted to quantify. Requires RPC for further clarification. Page 1 of 3
, VIRGINIA ELECTRIC AND POWER COMPANY STEAM GENERATOR EDDY CURRENT TUBE INSPECTION i GLOSSARY OF TERMS / ANNOTATIONS NON Non Quantifiable Indication Not Confirmed. An NOI which was not 4 confirmed by further RPC testing. pal Possible Axial Indication. Any signal having a vertical response lying in a flaw plane that is distorted / influenced by geometry changes. These signals will be subject to additional RPC testing in an attempt to further 2,larify the signal. PAN Possible Axial Indication Not Confirmed by RPC. A pal signal that was determined to be non-relevant by additional RPC testing. PCI Possible Circumferential Indication. Any signal having a vertical response lying in a flaw plane that is distorted / influenced by geometry changes. These signals will be subject to additional RPC testing in an attempt to
- further clarify the signal.
PCN Possible Circumferential Indication Not Confirmed by RPC. A PCI signal that was determined to be non-relevant by additional RPC testing. PMM Possible Mixed Mode Cracking. If a combination of circumferential and axial indications (I codes and/or SAA/SCA) are reported at an intersection, the isometric plot shall be reviewed for signal orientation that would imply that the signals do (or could) intersect (it is not necessary that they now intersect). If it appears that they do (or could) intersect, an additional report line of " PPM" must be made to allow for further review of the intersection. SAA Single Axial Anomaly. Describes a single axially oriented indication that does not meet the pal code requirements. sal Single Axial Indication. Describes a single axially oriented signal from Rotating Pancake probe data. SAL Single Axial Liftoff. Describes a single axially oriented indication signal that does not meet the SAA code requirements SCA Single Circumferential Anomaly. Describes a single circumferentially oriented indication that does not meet the PCI code requirements. SCI Single Circumferentially Oriented Indication. Describes a single circumferentially oriented indication signal from Rotating Pancake probe data. Circumferentially Oriented Indication (COI) is used if it is impossible to clearly detect the number of signals present. SCL Single Circumferential Liftoff. Describes a single circumferentially oriented indication signal that does not meet the SCA code requirements Page 2 of 3
