Attachment 5 RT Report

ET Report

the criteria in WDI-ET-004 that a flaw like indication have a linear extent for 3 or more data points, in the index direction corresponds to a distance of 0.120. If the index spacing is 0.025 then a flaw like indication must extend for 4 to 5 or more data points in the index direction.

The system calibration process resulted in having the Lissajous signals from circumferential flaws displayed down to the right and axial flaws displayed up to the left.

The scanning was performed axially using the same 0 degree reference and clockwise positive orientation. The flame cut end at the 0 degree location was used as the 0 axial reference. The scanning started at 1 below this flame cut and extended approximately 4.

Figure 1: 7010/Open Housing Scanner suspended from a fork truck performing a scan of Safety Nozzle A

Indication Summary NOZZLE A Four reportable ID linear circumferential indications were detected.

Please note that the date stamp on the computer screen is incorrect (1/05/2002) and should be 3/12/2008 in all cases.

Figure 2: Eddy Current C scan showing the SS pipe (top) (to ~ -2.3), DM weld (middle)

(to ~ -3.7) and SS clad carbon steel (bottom). The indications are located at approximately -2.4 axially.

Figure 3: Circumferential, linear indication #1 at 28 degrees, -2.40 with the 400 kHz and 100 kHz Lissajous patterns of a surface indication 0.36 long. The signal amplitude is approximately 50% of the 0.040 deep EDM notch.

Figure 4: linear indication #2 at 74 degrees, -2.36 with the 400 kHz and 100 kHz Lissajous patterns of a surface flaw 0.46 long. The signal amplitude is slightly more than the 0.040 EDM notch.

Figure 5: Circumferential linear indication #3 at 157 degrees, -2.28 with the 400 kHz and 100 kHz Lissajous pattern of a surface indication 0.25 long. The signal amplitude is approximately 60% of the 0.040 EDM notch.

Figure 6: Circumferential linear indication #4 at 339 degrees, -2.36 with the 400 kHz and 100 kHz Lissajous patterns of a surface indication 0.36 long. The signal amplitude is approximately 60% of the 0.040 EDM notch.

Figure 7: Permeability indication (PV) at 214degrees, -3.04. (There are two other PV indications at approximately 100 and 150 degrees) with the 400 kHz and 100 kHz Lissajous patterns Based on the available information from drawings and pictures, it appears that the 360 degree demarcation at approximately 2.3 corresponds to the SS pipe to inconnel weld interface. This would show that the ET indications are in the inconnel weld, near the SS interface. The lower 360 indication at approximately 3.7 is the remnant of the counterbore machining in the nozzle, as shown in Figure 7.

Figure 8: Picture of Nozzle A interior. The faint circumferential line in upper portion of the mirror image appears to be the transition between the SS pipe and the alloy 182 weld. The lower circumferential line appears to be from a slight mismatch between the original counterbore machined from the PZR head side and the final post welding machining done from the nozzle flange side. Both of these lines are clearly evident in the eddy current C scan images.

Nozzle B Figure 9: Nozzle B has no recordable indications (NDD) but shows the same SS to inconnel weld transition and counterbore to SS clad transition. (ID grinding area indicated in the region of 270 degrees, -3.2.)

Nozzle C Figure 10: Nozzle C displays the normal transitions and four very short indications in the weld zone. These indications have the phase angle of circumferential flaws but a C scan image display of axial flaws and do not extend for an index distance equal to 0.120, which is probably associated with some type of surface blemishes. All four indications are essentially the same.

Attachment 8 Comparison of manual vs encoded UT

Comparison of Manual vs. Encoded Phased Array Sizing Measurements Safety Nozzle A Port St Lucie Unit 1 Pressurizer

Objective

  • Evaluate manual phased array depth sizing measurements by comparison with encoded phased array data
  • Determine whether any of the reported flaws are connected to inside surface
  • Determine the origin of tip signals reported Note: Only axial scans for circumferential flaws were evaluated

© 2008 Electric Power Research Institute, Inc. All rights reserved. 2

Approach

  • Make general observations from the Port St Lucie Unit 1 (PSL) nozzle data
  • Compare PSL nozzle responses with those obtained from a nozzle that has never been in service

- Removed from Washington Nuclear Power Unit 3 (WNP) pressurizer

  • Perform side by side comparison of manual and encoded data

- Optimize views

- Determine if target is present

- Measure maximum extent

- Determine whether there is evidence that the reflector is connected to the inside surface

General Observations

  • Small fabrication flaws can be seen randomly spaced through out the entire weld for the entire circumference at varying amplitudes

- Encoded phased array vendor reported only larger flaws that had the procedurally defined amplitudes (10-15 percent average noise level)

  • Additional smaller flaws can be seen at lower amplitudes
  • All flaws reported by this technique were outside the required ASME Code examination volume with the exception of flaw 8
  • Data compared to data taken from canceled plant

- Similar indications noted in data

Flaw Profile Evaluation

  • Encoded phased array flaw profile data shows only the flaws reported by examination vendor
  • The manual phased array vendor flaw profile was overlaid over the encoded data profile
  • The profiles agree

- Missing data points in the encoded-data profile are from locations where the flaw indications were below the amplitude recording threshold of the encoded procedure

  • Flaw depth and length dimensions were measured to noise level and are considered to be conservative

Summary

  • Tip signals reported by the manual examination appear to be associated with embedded fabrication flaws randomly dispersed within the volume of the weld
  • None of the flaws appear to be connected to the inside surface or to each other
  • Flaws in nozzles B and C have same characteristics as the flaws in Nozzle A, but with lower flaw density
  • Comparison with similar welds from a canceled plant shows that these types of flaws are typical to the welding process used for fabrication

Devers ID#: 432-55-4637 Procedure: PDI-UT-IO; Revision: A; Addenda: 0 PDI Generic Procedure for the Ultrasonic Examination of Dissimilar Metal Piping Welds PDQS Rev: 0 Date of Issue: 20-Dec-02 Owner: Pert'onnance Demonstration Initi'ative Analysis SW Type/Rev: N/ A Hardware: N/ A Operator SW Type/Rev: N/ A Category: Piping Scan Application: Manual Exam Surface: Outside When "Length Sizing" is indicated, the 0,750 RMS acceptance criteria per the POl Program Description has been achieved.

When "Through Wall Sizing" is indicated, the 0.125 RMS acceptance criteria per the POl Program Description has been achieved, Tolerances for field applications as follows:

Diameter: Lower: .500" can be subracted from the minimum diameter demonstrated.

Upper: Diameters greater than 24" need not be demonstrated.

Thickness: Lower: 0.100" can be subtracted from the minimum thickness' demonstrated for both austenitic and ferritic Upper: 1.000" can be added to the maximum thickness demonstrated for ferritic material.

0.500" can be added to the maximum thickness demonstrated for austenitic material.

This candidate has met the practical requirements of Appendix VII: Yes Comments:

Limitations: 1 This procedure/candidate is not qualified for through wall sizing.

2 This~proct:dure/candid~te is not qualified for examinations perfonned from the cast stainless steel side ofa component.

3 This procedure/candidate is not qualified for examinations where the ultrasonic sound beam is required to propagate through an adjacent weld prior to impinging on the dissimilar metal weld. The POl 711 series sample is an example of this configuration.

4 Examination of safe-end replacement configurations, identified as 706 and 707 series configurations in the POl Program are qualified.

5 This procedure/candidate is qualified for examination from both single and dual sided access as applicable ..
