SUBJECT:
Relief Request Pertaining to Reactor Vessel Nozzle Inspections for Third 10-Year Interval, Revision This letter revises and replaces Reference 4 in its entirety. In Reference 4 OPPD indicated that we would provide the non-proprietary versions of the information needed for the subject relief requests by November 24, 2003. This submittal fulfills that statement.
In accordance with 10 CFR 50.55a(a)(3)(i), FCS is requesting relief for the third ten-year interval from inservice inspection requirements of the 1989 Edition no Addenda,Section XI of the ASME Boiler and Pressure Vessel Code for the surface examination of Class 1, Reactor Pressure Vessel (RPV) nozzle-to-safe end welds. The examination requirement is for a surface and volumetric examination of ASME Section XI, Examination Category B-F, "Pressure Retaining Dissimilar Metal Welds", Item No. B5.10, "Reactor Vessel NPS 4 or Larger."
- I FCS proposes to implement the requirements consistent with ASME Code Case N-615, "Ultrasonic Examination as a Surface Examination Method for Category B-F and B-J Piping Welds." FCS would implement the Code Case N-615 for the surface examinations for the six (6)
Reactor Pressure Vessel nozzle-to-safe end dissimilar metal welds, category B-F, item B5.10 for nozzle inspections performed during the 2003 refueling outage.
Pursuant to 10 CFR 2.790, OPPD requests that the proprietary information herein be withheld from public disclosure. Framatome ANP, INC. considers this information to be proprietary as justified in the supporting affidavit (Attachment B). Attachments C and D are the proprietary Framatome documents, including a copy with the proprietary information annotated (i.e., a clean
_Ap)t Emplopent with Equal Opportunity
U. S. Nuclear Regulatory Commission LIC-03-0154 Page 2 copy and an annotated copy). Attachments E and F are the non-proprietary (redacted) versions of Attachments C and D with the proprietary information deleted.
FCS requests approval of the proposed Relief Request, RR-9, by May 15, 2004.
Commitments made to the NRC in this letter are listed in Attachment G. If you have any questions or require additional information, please contact Dr. R. L. Jaworski at (402) 533-6833.

In accordance with 10 CFR 50.55a(a)(3)(i), FCS is requesting relief for the third ten-year interval from inservice inspection requirements of the 1989 Edition no Addenda,Section XI of the ASME Boiler and Pressure Vessel Code for the surface examination of Class 1, Reactor Pressure Vessel (RPV) nozzle-to-safe end welds. The examination requirement is for a surface and volumetric examination of ASME Section XI, Examination Category B-F, "Pressure Retaining Dissimilar Metal Welds", Item No. B5.10, "Reactor Vessel NPS 4 or Larger."
FCS proposes to implement the requirements consistent with ASME Code Case N-615, "Ultrasonic Examination as a Surface Examination Method for Category B-F and B-J Piping Welds." FCS would implement the Code Case N-615 for the surface examinations for the six (6) Reactor Pressure Vessel nozzle-to-safe end dissimilar metal welds, category B-F, item B5.10 for nozzle inspections performed during the 2003 refueling outage.
JUSTIFICATION FOR GRANTING RELIEF The Ultrasonic examination techniques utilized for this examination are qualified by demonstration to meet the requirements of Code Case N-615. The use of these qualified techniques assures that the dissimilar metal welds remain free of service related flaws thus enhancing quality and ensuring plant safety and reliability.
The work required to support these surface examinations without implementing Code Case N-615 includes labor to remove/replace the cover plates over the six (6) reactor nozzles, and labor to remove/replace the sand above the nozzles. The surface inspections of the outside weld surfaces are limited due to the tight space and no access to the very bottom of the welds. The area dose rate is estimated to be about 120 mr/hr with the head on. The dose in the cavity surrounding the nozzles is unknown. An ex-core detector was removed from one of the nozzle boxes last outage and read 40,000 mr/hr. The surface dose rate near the welds would be very close to these detectors. Therefore, the implementation of this Code Case reduces the radiation exposure by several man-rem while providing an acceptable level of quality and safety.

Background
The qualification documentation and the procedure for the qualification of the Ultrasonic Examination Technique used at the Fort Calhoun Station during the 2003 refueling outage to perform the surface examinations of the reactor vessel B-F welds are included in Attachment B and Attachment C respectively.
The ultrasonic examinations were performed during the fall 2003 refueling outage and no surface indications were identified.

Results from ID & OD Clad Safe-end Mockup AFRAMATOME ANP Block Demonstration for Fort Calhoun Objectives:
The objective of this demonstration was to document the detection of opposite surface cracking through the ID & OD cladding surrounding the safe end. A secondary objective was to document the detection of side drilled holes through the welds.
Background:
Prior to the 2003 RFO RPV 10-year examination, the need to demonstrate Framatome ANP inspection techniques on component configurations unique to Fort Calhoun was required.
The safe ends employed by Fort Calhoun are made of forged stainless steel (CCSS) with cladding on both ID and OD surfaces. To facilitate this demonstration, a block with cladding on both ID and OD surfaces was obtained from see Figure 1. Framatome ANP P01 -- Deleted: Indian Point l procedure 54-ISI-821 was used as a template for the opposite surface flaw detection. it was 54-ISI-821 that served as a foundation for the development of 54-ISI-189 that became the specific examination procedure for use at Ft. Calhoun.
Summary:
The results of the demonstration show that opposite side cracks were detected., . Deleted: The sizing results fromthe opposite side scan shows an average length sizing error of 40.190 (over Demonstration Setup: call), an average depth sizing error of O.077' (under call). I Inspection of the demonstration block was performed at EPRI with Framatome ANP X/Y scanner (see Figure 2). The cladding on the ID surface is hand blended to a smooth surface when compared to the OD clad surface roughness (See Figure 1) which is also hand blended but to as lesser extent. The opposite side inspection was performed to the requirements of 54-ISI-821 with the exception of scanning sensitivity (material noise set to 10% FSH), transducer selection, and the acquire range (larger than procedural requirements). Both axial (normal to side drilled holes) and circumferential scans (parallel to side drill holes) were made on each surface.
The demonstration block contains two surface connected thermal fatigue cracks located in the safe end material on the surface representing the OD. The cracks are identified as "G" and "H" and have the following dimensions:
- Flaw l Orientation ' Length I- ' Ratio ; Depth l -Depth% l. Tilt -l G Circ. 0.500- 1 2.5:1 0.200" 8% 0° H Axial 0.500" 2.5:1 0.200" 8% 0 Deleted: THIS DOCUMENT IS THE PROPERTY OF FRAMIATOME ANP, INC.

- 8. Scanning Requirements 8.1 The temperature of the component to be examined shall not exceed 1200 F.
8.2 The scanner shall be calibrated to provide accurate positional information in relationship to the component. This will be accomplished by using the applicable operating instruction (01) for the scanner being used for the examination.
8.3 The system operator shall select the appropriate scan plan to be executed from the previously entered database.
- 9. Data Analysis 9.1 Refer to Figure 5 during data analysis for a flow chart of the analysis process 9.2 Weld fabrication and examination data histories, if available, shall be reviewed prior to analysis of the ultrasonic examination data.
9.3 Following the completion of scanning, the ultrasonic data shall be reviewed to assure that the data quality (contact, signal to noise, coupling, etc.) is adequate to properly perform an effective evaluation of the examination data. The data shall also be reviewed to verify that the scanning parameters specified in Sections 6 and 7 were utilized and sufficient. If any of the scan parameters require adjustment, the scan plan shall be revised and rescans performed as necessary. All subsequent scanning shall be made using the revised parameters.
9.4 The analyst shall update and apply the geometry file by inputting the beam angle, beam direction, transducer offsets, and component geometry as applicable, (refer to the scan plan) for each scan to assure that the proper location of indications are reported.

9.4.2 The transducer beam orientation is used to set the transducer beam direction with respect to the index coordinates for the specific channel. The range of this parameter is 0 to 360 degrees. The +X orientation is 0 degrees and means that the transducer beam direction is in the positive index direction. Likewise, the -X orientation is 180 degrees and is the negative index direction.

Indications are defined as coherent patterns of signals observed in the B, C,or D-scan images that exhibit target motionin the beam direction. The following steps should be followed in the initial evaluation process of the ultrasonic data to aid determining the origin of the recorded reflectors.
9.5.1 Recall the data for the channel being analyzed. Using the expand" feature, display the weld volume from a point at least before the componenrtQP_- -- eee:05 I surface to -,past the OD surface.- -------------- eee:10 9.5.2 Adjust the color palette range to provide resolution of the various reflectors throughout the scan. Several palette ranges should be evaluated in order to provide optimum Image contrast. Too small of a color range may mask flaw indications with the background noise of the component, while too large of a palette range may not properly display low amplitude indications.
9.5.3 Investigate areas of suspect indications in accordance with paragraphs 9.7 and 9.8. At this point the data that projects into the examination volume should be investigated to view the full target motion of the suspected surface connected flaws. For weld configurations that produce geometric responses due to the inside surface the data shall be evaluated with beam angle correction applied and removed to properly evaluate potential flaw indications that may be obscured by the geometric responses. This allows the analyst to identify indications that have target motion, which may have been obscured in the angle corrected views.
9.6 Indications shall be classified as either geometric or non-geometric (flaw indications).
The following paragraphs provide some general guidelines when evaluating examination data with suspected geometric ndications.
9.7 Geometric indications are likely to be detected from weld counterbores and weld roots when the beam is directed toward the reflector. This type of indication will normally exhibit a fairly continuous pattern in the D-scan and C-scan images and may be localized in areas or extend a full 360' around the weld. Geometric indications usually exhibit consistent target motion across the length of the indication. For the examinations being performed in accordance with this procedure from the inside surface, geometric indications are usually detected for shop weld configurations from weld root or counterbore conditions.

FRAMATOME-ANP NONDESTRUCTIVE EXAMINATION PROCEDURE Procedure ID Automated Ultrasonic Examination of Welds for Detection of OD Initiated Flaws 54-ISI- 189-00 54-PO-189-01 9.8.2 The intent of this procedure is to detect outside surface connected cracks, however the techniques utilized may also detect other types of flaws which have length and depth (lack of fusion, slag) that have to be evaluated by the analyst.
9.8.3 Cracks are surface connected and may appear as isolated indications or multiple related indications within the examination region. When a flaw indication is embedded in a high amplitude surface geometric response the target motion of the flaw response will normally extend through the geometric response.
9.8.3.1 The position of the flaw in relationship to the transducer position, geometric configuration restrictions, flaw orientation (tilt and skew) and position (side of the weld) will affect the flaw response, i.e. a surface flaw may not provide target motion to the surface if the geometry restricts transducer contact over the flaw or the flaw orientation is not favorable to the side of the weld where the transducer is positioned, etc.
Questionable indications shall be evaluated from both sides of the weld to ensure proper interpretation of the data.
9.8.4 Non-geometric indications that connect to the outside surface shall be considered planar type flaws. Indications that produce images, which display target motion that extends to or beyond the outside surface, (when viewing the B and D scan displays), shall be considered surface connected indications.
- 10. Data Recording 10.1 The reflector position, depth, and amplitude at the point of maximum amplitude shall be documented for geometrical or fabrication type indications 50% or greater than the primary reference level. These shall be identified as geometric or fabrication indications on the data sheet. These types of indications are recorded for reference only when comparing past and future examination results.
10.2 Surface connected flaw indications shall be reported regardless of amplitude. Data from other scan directions and/or transducers should be used to confirm the presence of flaw indications where possible.

Results from ID & OD Clad Safe-end Mockup A Block Demonstration for Fort Calhoun FRAMATOME ANP Objectives:
The objective of this demonstration was to document the detection of opposite surface cracking through the ID & OD cladding surrounding the safe end. A secondary objective was to document the detection of side drilled holes through the welds.
Background:
Prior to the 2003 RFO RPV 10-year examination, the need to demonstrate Framatome ANP inspection techniques on component configurations unique to Fort Calhoun was required.
The safe ends employed by Fort Calhoun are made of forged stainless steel (CCSS) with cladding on both ID and OD surfaces. To facilitate this demonstration, a block with cladding on both ID and OD surfaces was obtained from (see Figure 1). Framatome ANP PDI procedure 54-ISI-821 was used as a template for the opposite surface flaw detection. It was 54-1SI-821 that served as a foundation for the development of 54-ISI-189 that became the specific examination procedure for use at Ft. Calhoun.
Summary:
The results of the demonstration show that opposite side cracks were detected.
Demonstration Setup:
Inspection of the demonstration block was performed at EPRI with Framatome ANP X/Y scanner (see Figure 2). The cladding on the ID surface is hand blended to a smooth surface when compared to the OD clad surface roughness (See Figure 1) which is also hand blended but to as lesser extent. The opposite side inspection was performed to the requirements of 54-ISI-821 with the exception of scanning sensitivity (material noise set to 10% FSH), transducer selection, and the acquire range (larger than procedural requirements). Both axial (normal to side drilled holes) and circumferential scans (parallel to side drill holes) were made on each surface.
The demonstration block contains two surface connected thermal fatigue cracks located in the safe end material on the surface representing the OD. The cracks are identified as "G" and H" and have the following dimensions:
Flaw Orientation 1 Le'ngth r.Ratio Depthe 'Depth% -Tilt..'
G Circ. 0.500" 2.5:1 0.200" 8%
H Axial 0.500" 2.5:1 0.200" 8% 00 l Axial defined as normal to the weld.

9.3 Following the completion of scanning, the ultrasonic data shall be reviewed to assure that the data quality (contact, signal to noise, coupling, etc.) is adequate to properly perform an effective evaluation of the examination data. The data shall also be reviewed to verify that the scanning parameters specified in Sections 6 and 7 were utilized and sufficient. If any of the scan parameters require adjustment, the scan plan shall be revised and rescans performed as necessary. All subsequent scanning shall be made using the revised parameters.
9.4 The analyst shall update and apply the geometry file by inputting the beam angle, beam direction, transducer offsets, and component geometry as applicable, (refer to the scan plan) for each scan to assure that the proper location of indications are reported.
9.4.1 Curvature correction shall be applied to adjust the data to the proper depth and circumferential position when using flat calibration blocks.
9.4.2 The transducer beam orientation is used to set the transducer beam direction with respect to the index coordinates for the specific channel. The range of this parameter is 0 to 360 degrees. The +X orientation is 0 degrees and means that the transducer beam direction is in the positive index direction. Likewise, the -X orientation is 180 degrees and is the negative index direction. The analyst can verify that the correct beam direction orientation has been entered by verifying that the proper target motion is display on the screen based on the scan plan information.
9.5 The recorded data shall be analyzed to the extent that the analyst can determine the classification and location of the indications that meet the data recording criteria.

FRAMATOME-ANP NONDESTRUCTIVE EXAMINATION PROCEDURE Procedure ID Automated Ultrasonic Examination of Welds for Detection of OD Initiated Flaws 54-ISI-189-00 54-PQ-189-01 Indications are defined as coherent patterns of signals observed in the B, C, or D-scan images that exhibit target motion in the beam direction. The following steps should be followed in the initial evaluation process of the ultrasonic data to aid determining the origin of the recorded reflectors.
9.5.1 Recall the data for the channel being analyzed. Using the "expand" feature, display the weld volume from a point at least" before the component OD surface to - past the OD surface.
9.5.2 Adjust the color palette range to provide resolution of the various reflectors throughout the scan. Several palette ranges should be evaluated in order to provide optimum image contrast. Too small of a color range may mask flaw indications with the background noise of the component, while too large of a palette range may not properly display low amplitude indications.
9.5.3 Investigate areas of suspect indications in accordance with paragraphs 9.7 and 9.8. At this point the data that projects into the examination volume should be investigated to view the full target motion of the suspected surface connected flaws. For weld configurations that produce geometric responses due to the inside surface the data shall be evaluated with beam angle correction applied and removed to properly evaluate potential flaw indications that may be obscured by the geometric responses. This allows the analyst to identify indications that have target motion, which may have been obscured in the angle corrected views.
9.6 Indications shall be classified as either geometric or non-geometric (flaw indications).
The following paragraphs provide some general guidelines when evaluating examination data with suspected geometric indications.
9.7 Geometric indications are likely to be detected from weld counterbores and weld roots when the beam is directed toward the reflector. This type of indication will normally exhibit a fairly continuous pattern in the D-scan and C-scan images and may be localized in areas or extend a full 3600 around the weld. Geometric indications usually exhibit consistent target motion across the length of the indication. For the examinations being performed in accordance with this procedure from the inside surface, geometric indications are usually detected for shop weld configurations from weld root or counterbore conditions. Care should be taken when analyzing data near geometric indications as they may obscure flaw signals.
9.8 Indications that cannot be dispositioned as geometric indications and meet the applicable criteria specified below shall be classified as flaw indications.
9.8.1 Flaw indications usually exhibit themselves as localized areas and peak amplitudes greater than.

FRAMATOME-ANP NONDESTRUCTIVE EXAMINATION PROCEDURE Procedure ID Automated Ultrasonic Examination of Welds for Detection of OD Initiated Flaws 54-ISI-189-00 54-PQ-189-01 9.8.2 The intent of this procedure is to detect outside surface connected cracks, however the techniques utilized may also detect other types of flaws which have length and depth (lack of fusion, slag) that have to be evaluated by the analyst.
9.8.3 Cracks are surface connected and may appear as isolated indications or multiple related indications within the examination region. When a flaw indication is embedded in a high amplitude surface geometric response the target motion of the flaw response will normally extend through the geometric response.
9.8.3.1 The position of the flaw in relationship to the transducer position, geometric configuration restrictions, flaw orientation (tilt and skew) and position (side of the weld) will affect the flaw response, i.e. a surface flaw may not provide target motion to the surface if the geometry restricts transducer contact over the flaw or the flaw orientation is not favorable to the side of the weld where the transducer is positioned, etc.
Questionable indications shall be evaluated from both sides of the weld to ensure proper interpretation of the data.
9.8.4 Non-geometric indications that connect to the outside surface shall be considered planar type flaws. Indications that produce images, which display target motion that extends to or beyond the outside surface, (when viewing the B and D scan displays), shall be considered surface connected indications.
- 10. Data Recording 10.1 The reflector position, depth, and amplitude at the point of maximum amplitude shall be documented for geometrical or fabrication type indications 50% or greater than the primary reference level. These shall be identified as geometric or fabrication indications on the data sheet. These types of indications are recorded for reference only when comparing past and future examination results.
10.2 Surface connected flaw indications shall be reported regardless of amplitude. Data from other scan directions and/or transducers should be used to confirm the presence of flaw indications where possible.
10.3 The location, amplitude, and length shall be documented for each flaw indication as described in the following paragraphs:
10.3.1 The location of the flaw along the pipe axis (for circumferential flaws) or around the circumference (for axial flaws) shall be recorded. The surface position shall be measured at the point where the target motion intersects the outside surface of the component. Where the target motion of a surface connected flaw does not extend to the outside surface due to flaw position relative to the Page 16 of 24
FRAMATOME-ANP NONDESTRUCTIVE EXAMINATION PROCEDURE Procedure ID Automated Ultrasonic Examination of Welds for Detection of OD Initiated Flaws 54-ISI-189-00 54-PQ-189-01 geometry, extend the target motion following the same angle until it intersects the outside surface to determine the flaw position.
10.3.2 Record the maximum amplitude of the indication. For many flaw indications the flaw response may be saturated. If the flaw response is saturated, record the maximum measured amplitude and also indicate that the flaw response is saturated.
10.3.3 Length:
10.3.3.1 For determining the flaw end points the B-scan should be expanded to display the outer 1.0" of material to properly provide the surface position of the indication. Length measurements should be taken at the end points along the flaw axis where the flaw image.
10.3.3.2 For length sizing of circumferentially oriented flaws the measurements shall normally be taken from the flaw orientation or surface geometry condition provides a better response.
10.4 Areas of limited examination coverage shall be recorded in the examination report. Limitation of coverage of the examination volume from the inside surface of the component is usually due to surface geometry that does not allow the transducer to be scanned over the surface or maintain contact. These regions can be identified using the B, C, and D-scan images. To determine the amount of limited coverage measure the areas of transducer liftoff on the image. Both the axial and circumferential extents shall be documented for each transducer and beam direction. The surface profile scan may be performed if more detailed evaluation of the surface condition is required to provide a more precise estimate of limited coverage.
- 11. Rescans/Supplemental Scans 11.1 The analyst may identify additional scans in order to satisfy the requirements of this procedure or to re-perform scans of areas that are considered inadequate.
11.2 Supplemental examinations, performed in addition to the examinations required by procedure, are acceptable to provide additional information to help resolve or confirm results, provided they are not used to overturn results obtained with the qualified techniques or provide additional coverage of limited areas.
11.3 Data analysis personnel shall be responsible for initiating all instruction for Rescans or Supplemental scans.
