In Reference 1, the NRC granted FPL Energy Duane Arnold relief from the ASME Code, Section XI, pursuant to 10 CFR 50.55a(a)(3)(ii), to extend the inspection of two Duane Arnold Energy Center (DAEC) Reactor Pressure Vessel (RPV) welds (VLA-001 and VLA-002) due to be performed in the 3 rd 10-year In-Service Inspection (ISI) interval to the next refuel outage (RFO20). RFO20 began on February 4, 2007. The DAEC is currently in the 4 th 10-year ISI interval, which began on November 1, 2006.
As part of our preparation for an inspection of the current DAEC ISI program, we received several written questions from an inspector from the NRC Region III
                                                                                           ,40+7

NG-07-0143 February 14, 2007 Page 2 of 3 office. The questions raised issues with respect to the adequacy of qualification of the procedure being used to conduct the deferred weld examinations noted above. Specifically, the current equipment configuration (coaxial cable sizes and lengths and associated number of connections) is different from that in the ISI vendor's documentation of the as-tested/as-qualified configuration.
Our review of the issue has identified that this request for relief to use Appendix VIII, Article VIII-4000 is appropriate to clearly justify our use of the cable configuration currently on-site, since the code of record for the 3 rd ISI interval at the DAEC (1989 Edition with no addenda) does not expressly authorize an equivalence evaluation of alternative cable configurations from the as-tested configuration. In addition, because a similar equipment configuration was used to conduct the RPV weld examinations performed during RFO19, relief is also requested retroactively for the examinations of those welds (VLB-A001, VLB-A002, VLC-B001, VLC-B002, VLD-B001, VLD-B002, and VCB-C005).
NRC approval of the requested relief is needed by February 23, 2007, the scheduled start date for conducting the ASME Class I leaktest of the RPV. The RPV cannot be pressurized until the DAEC is in compliance with the Code or has been granted relief.
Attachment A provides FPL Energy Duane Arnold's request for relief.
Attachment B provides the IHI Southwest Technologies Inc. (ISwT) Technical Evaluation Regarding Alternate Cable Configuration Used for Reactor Vessel Shell Weld Examinations from the Inside Surface at Duane Arnold Energy Center.
There is no practical alternative to the requested relief. The examination of the RPV welds previously conducted during RFO19 was not deferred to this RFO, as it was believed at the time of the previous relief request (Reference 2), that the exams had been conducted in accordance with the Code. Requiring the re-performance of the examinations during the current RFO would be outside the DAEC 3 rd 10-year interval.
This letter contains no new commitments nor revises any previous commitments.

: 4.      Reason for Request The IHI Southwest Technologies Inc. (ISwT) Ultrasonic Examination Procedures (ISwT-PDI-AUT1 and ISwT-PDI-AUT2) included the following essential variables for the cables that were used in the performance demonstration:
Cable Type                  Maximum Length               Number of Connectors RG58                         1018 feet                   13 RG174                       80 feet IHI Southwest Technologies Inc. has changed the essential variables for the cables in the procedure (ISwT-PDI-AUT1) to the following:
Cable Type                  Maximum Length               Number of Connectors RG58                         1350 feet                   20 RG174                       230 feet Micro cable                 5 feet FPL Energy Duane Arnold used the following cables at the DAEC when performing the examinations of the above mentioned welds in the 2005 refueling outage:

However, for the over-all system configuration, the length of cable is shorter.
: 5.      Proposed Alternative and Basis for Use Pursuant to 10 CFR 50.55a(a)(3)(i), the following alternative is requested on the basis that the proposed alternative provides an acceptable level of quality and safety.
Page 3 of 6

ATTACHMENT A Appendix VIII, Article VIII-4000 allows procedure modifications, including substitution and/or replacement of major system components (pulsers, receivers, and search units), as well as introducing alternate methods of system calibration without re-qualification.
FPL Energy Duane Arnold requests retroactively the use of Appendix VIII, Article VIII-4000 for Refueling Outage 19 (2005) to allow the use of cable type RG174 with a maximum length of 230 feet and 5 feet of Micro Cable with 6 connectors in lieu of the 1018 feet of RG58 cable and 80 feet of RG174 with a total of 13 connectors without re-qualification of ISwT reactor vessel procedures ISwT-PDI-AUT1 and ISwT-PDI-AUT2 which is presently required by Appendix VIII, paragraph VIII-3140. FPL Energy Duane Arnold also requests the use of Appendix VIII, Article VIII-4000 to allow the use of cable type RG1 74 with a maximum length of 230 feet and 6 connectors for Refueling Outage 20 (2007).
In 1995, ISwT (then Southwest Research Institute) qualified ISwT-PDI-AUT1 and ISwT-PDI-AUT2 Revision 0 procedures for inside surface examination of pressurized water reactor vessel shell welds. These procedures do not utilize a basic calibration block to establish system sensitivity. Instead system sensitivity is established based on material noise observed on the actual component being examined. This technique eliminates any variations in sensitivity that could be incurred if the calibration block material was not identical to the vessel material.
Another unique aspect of these procedures is that they do not rely on amplitude measurement to discriminate flaws from non-relevant reflectors. As long as the indication has at least a 2:1 signal to noise ratio and has flaw image display characteristics, the indication is evaluated as a flaw. Because of these unique aspects, the impact of cable configuration on these procedures is minimized.
Instead system sensitivity is established based on material noise observed on the actual component being examined. Thus, provided an acceptable signal to noise ratio can be obtained, the change in cable configuration has no appreciable affect on the system capability to detect flaws.
In 2001, ISwT began using a scanner whose size and function were capable of accessing the inside surface of welds in a Boiling Water Reactor (BWR) vessel.
Because of the small size and restricted areas of operation in a BWR annulus, the type of search unit cable used for the initial procedure qualifications for ISwT-PDI-AUT1 and ISwT-PDI-AUT2 Revision 0 in 1995 was not feasible for use with this tool.
With exception of DC resistance values, the cable types RG174, RG58, and Micro Cable are electrically equivalent. The rated nominal impedance and capacitance values for these cable types are equivalent. The DC resistance values for the RG174 and Micro Cable are higher per unit length, but the calculated change in resistance has a negligible effect on signal presentation and signal to noise ratio.
Page 4 of 6

ATTACHMENT A ISwT performed a system equivalency comparison between the PDI essential variable cable configuration and the cable configuration listed in the new procedure for BWR vessels. The comparison used a "worst case" BWR cable configuration that could be necessary if the data acquisition system was physically located outside of the reactor building. This "worst case" configuration consisted of 1,350 feet of RG58, plus 230 feet of RG174, plus 5 feet of Micro Cable, with 20 connectors. The results of.the comparison can be found in Attachment B. The equivalency demonstration was performed in accordance with Appendix VIII, Supplement 1, with the exception that a steel reference block was used in lieu of the glass block recommended in Supplement 1. All aspects of the procedure were held constant and the system center frequency and bandwidth were measured for both cable configurations and each type of probe specified in the procedures. The comparison identified that the center frequency and bandwidth of the total system were within the acceptance criteria contained in Appendix VIII. The measurements were within the acceptance criteria of Section VIII-41 10(h)(4) for systems with bandwidths greater than 30%. The total cable length actually used for DAEC examinations (235 feet in 2005 and 230 feet in 2007) is significantly less than the total cable length originally qualified (1098 feet).
In addition, an empirical cable demonstration was performed at the DAEC which demonstrated signal amplitude is slightly improved when using the typical BWR cable configuration (235 feet) compared to the original cable configuration and that signal to noise ratios are relatively consistent between either cable configuration.
Based on the above discussion, allowing the cable configuration change without re-qualification similar to the substitution and/or replacement of major system components as allowed by Appendix VIII, Article VIII-4000, provides an acceptable level of quality and safety.
: 6.      Duration of Proposed Alternative This alternative will be used for the remainder of the DAEC third ten-year interval and the entire fourth ten year interval. The current ten-year interval for the DAEC is the fourth interval, however Reference 1 extended the third 10-year inservice inspection (ISI) interval for reactor vessel welds VLA-AO01 and VLA-A002 to the end of refueling outage 20. This relief is also requested to be retroactive to the third ten-year interval for welds VLB-AO01, VLB-A002, VLC-B001, VLC-B002, VLD-BOO1, VLD-B002, and VCB-C005 inspected during Refueling Outage 19.

Technical Evaluation Regarding Alternate Cable Configuration Used for Reactor Vessel Shell Weld Examinations from the inside surface at Duane Arnold Energy Center

==Reference:==
FPL Energy Purchase Order No. KI 14303

==Dear Mr. Park:==

Based on questions identified by a Region Ill USNRC inspector regarding the acceptability of the IHI Southwest Technologies (ISwT) procedures, and Duane Arnold Energy Center's (DAEC) request for a technical evaluation in response to those questions, I am pleased to offer this evaluation and supporting documentation.
At the heart of the issue is a change in the cable configuration that is listed as an essential variable in lSwT's procedures, made to allow the use of a new scanner specifically designed to improve examination coverage on Boiling Water Reactor (BWR) vessel shell welds. This scanner design allows examination coverage of some BWR vessel welds that are normally not accessible for examination. Even in cases where examination access is available from the outside of the vessel, this scanner allows a significant reduction in radiation exposures by avoiding personnel entrances into high radiation areas in the BWR drywell.
Attachment I contains a discussion of the events to date relative to these issues. contains a summary of a cable electrical evaluation performed by lSwT in 2001. Attachment 3 addresses a system equivalency demonstration performed by lSwT in 2001 using guidance from Appendix VIII, Supplement 1. Attachment 4 contains a summary of an empirical cable comparison performed by ISwT at DAEC along with supporting data.

Based on a review of the evaluations and demonstrations performed by IHI Southwest Technologies (ISwT) as further described and documented in the attachments to this letter, ISwT's position is that the inspection procedures previously used at DAEC RFO 19, and that are also planned for use during RFO20, are not only technically equivalent to the procedures that were initially qualified under the Performance Demonstration Initiative (PDI) Program in 1995, but that the changes to the cable configurations were made in a manner consistent with the intent of ASME Section Xl, Appendix VIII.
Sincerely, Grady Lagleder President IHI Southwest Technologies

Attachment I Discussion

===Background===
IHI Southwest Technologies (formerly the NDE Services Department of Southwest Research Institute or SwRI) has been performing Automated Ultrasonic Examinations of Reactor Pressure Vessels since approximately 1970. ISwT provides these services for both Pressurized Water Reactors (PWR) and Boiling Water Reactors (BWR).
In the late 1980s, ASME Section XI began development of Appendix VIII "Performance Demonstration for Ultrasonic Examination Systems", which was published in the 1989 Addenda.
In the early 1990s the industry formed the Performance Demonstration Initiative (PDI) for the purpose of implementing the Appendix VIII requirements.
InitialProcedure Qualification In 1995, ISwT (then SwRL) qualified a set of procedures for inside surface examination of reactor vessel shell welds. These procedures were designed to function with ISwT's PWR vessel inspection system and the open access available when performing PWR vessel inspections with the core barrel removed. ISwT's procedures were unique in several ways. They do not utilize a basic calibration block to establish system sensitivity. Instead system sensitivity is established based on material noise observed on the actual component being examined. This eliminated any variations in sensitivity that could be incurred if the calibration block material was not identical to the vessel material. Another unique aspect of these procedures is that they do not rely on amplitude measurement to discriminate flaws from non-relevant reflectors. As long as the indication has at least a 2:1 signal to noise ratio and has flaw image display characteristics, the indication is evaluated as a flaw. Because of these unique aspects, the impact of cable configuration on these procedures is minimized. In fact, during ISwT's initial procedure qualification activity, an argument was presented to not consider this information essential, since, within typical operating situations, cable length and configuration will not have a significant affect on inspection results when using these procedures. Although the PDA conducting the qualification agreed with ISwT's position from a technical viewpoint, it was determined that cable configuration must be identified in the procedure as an essential variable simply because it was listed as an essential variable in Appendix VIII. The cable configuration used for this initial qualification was 1,018 feet of RG58, plus 80 feet of RG 174, with 13 connectors.
Adaptation to AIJS Scannerfor BWR Vessel Examinations In 2001, in response to the need for increased examination coverage of BWR reactor vessel welds, particularly those where outside surface inspection access was not available, ISwT introduced a new scanner that, due to it's size and function, could access the weld inside surface

in the very limited-access annulus regions between the BWR vessel shell and the core shroud.
This tool not only had potential for increasing inspection coverage, but would also significantly reduce radiation exposure to personnel because the examinations would be conducted from the refuel floor instead of inside the drywell. Because of the small size and restricted areas of operation in a BWR annulus, the type of search unit cable used for the initial procedure qualifications in 1995 was not feasible for use with this tool. Other aspects of the previously qualified procedures were determined to be applicable and ISwT proceeded to adapt the previously qualified procedures to this tool.
Justificationfor Cable Modifications Because of the time and expense associated with a reactor vessel procedure qualification (ISwT's initial automated vessel procedure qualification took over 3 months and cost approximately
$1,000,000), and since it was strongly believed that the necessary cable reconfiguration would not have a detrimental affect on the performance of these procedures, ISwT investigated opportunities to make this procedure change without a complete procedure re-qualification.
ISwT reviewed the Appendix VIII requirements, consulted with PDI personnel, consulted with in-house engineering personnel, and proceeded to perform several demonstrations and evaluations in lieu of undertaking a complete procedure re-qualification, believing the process to be in compliance with the intent of Appendix VIII.
Appendix VIII, Article VIII-4000 allows procedure modifications, including substitution and/or replacement of major system components (pulsers, receivers, and search units), as well as introducing alternate methods of system calibration without re-qualification. ISwT felt at that time, and still does, that it was ASME's intent to allow minor modifications to systems and procedures without re-qualification if a suitable technical evaluation or system equivalency demonstration can be performed.
Prior to performing an equivalency demonstration, ISwT performed an electrical evaluation of the cable types intended for use. With exception of DC resistance values, the cable types used by ISwT are electrically equivalent. This evaluation is addressed in more detail in Attachment 2.
In 2001, ISwT performed a system equivalency demonstration using a PWR cable configuration and a 'worst case' BWR cable configuration that would be necessary if the data acquisition system was physically located outside of the reactor building. The PWR cable configuration was slightly shorter than the originally qualified cable length (65 feet less), which bounded the intended comparison. The BWR 'worst case' configuration consisted of 1,350 feet of RG58, plus 230 feet of RGI174, plus 5 feet of micro coaxial cable, with 20 connectors. Although this
'worst case' cable configuration was never actually used in the field, it provided information that helped substantiate ISwT's claims during the original 1995 procedure qualification that cable configuration is not truly an "essential" variable when using these types of procedures. The equivalency demonstration was performed using guidance from Appendix VIII, Supplement 1, with the exception that a steel reference block was used in lieu of the glass block recommended in Supplement 1 and a contact setup was used in lieu of the immersion setup. Other aspects of the qualified procedure were held constant and the system center frequency and bandwidth were

measured for both cable configurations and each type of probe specified in the procedures. The measurements were within the equivalency criteria of VIII-4110 for systems with bandwidths greater than 30% (as documented in the original procedure and as measured again for this comparison). The results of this equivalency comparison are included as Attachment 3.
Empirical Comparison Performedin 2007 In addition to the measures taken in 2001, 1SwT also performed an empirical comparison of the three cable configurations using the entire ultrasonic system at Duane Arnold Energy Center (DAEC). Reference signals from each type of search unit were compared with each of the cable configurations (original qualification, DAEC RFOI 9, and DAEC RFO20) and all three configurations were shown to be within 2dB. Slightly less system gain was required to bring the reference signal to 80% full screen height when using the RFOI9 and RFO20 cable configurations. A-scan presentations for each cable configuration indicate no significant degradation in signal to noise ratio. The results of this comparison are described in more detail in Attachment 4.
Summary Based on the following key points, ISwT's position is that the cable configuration change required for adaptation to the AIRIS scanner will not have a detrimental effect on the quality of examinations performed using the AIRIS scanner and that the process used by ISwT to justify the substitution of an alternate cable configuration was not in violation of Code intent.
: 1) The impedance and capacitance values for the substituted cable are equivalent.
: 2) Even though the DC resistance values for the substituted cable are different, the increase in resistance has a negligible effect on procedure performance due to the equipment used, the methods used for setting system sensitivity, and the methods used for flaw discrimination.
: 3) The system equivalency comparison performed using guidance from Appendix VIII, Supplement I demonstrated that the center frequency and bandwidth of the total system with the 'worst case' cable configuration were still within the system equivalency criteria contained in Appendix VIII.
: 4) The empirical cable comparison performed at DAEC shows that signal to noise ratios are very similar and that overall system sensitivity is within 2 dB with either cable configuration, again showing that cable configuration changes (within practical limits) are not a significant issue.
: 5) The total cable length actually used by lSwT at DAEC and for all previous BWR examinations (235') is less than the cable length originally qualified.
: 6) The total number of connectors actually used by lSwT at DAEC and for all previous BWR examinations (6-8) is less than the number of connectors originally qualified.
: 7) Discussions with various industry experts in 2001, and again in 2007, verify that it was not the intent of Appendix Vill to limit the use of Supplement I system equivalency demonstrations to Pulsers, Receivers, and Search Units.

Attachment 2 ISwT Cable Electrical Evaluation Prior to initiating the cable modifications for the AIRIS scanner, ISwT performed an evaluation of the specifications for the different types of cables used by ISwT. Each of the three cable types used (RG-58, RG-174, and the special small diameter micro cable) is a co-axial insulated cable consisting of a braided shield surrounding a stranded core. The physical characteristics of these cable types (outside diameter, insulation thickness, shield configuration, etc.) is different for each, but that alone should have no impact on the inspection results.
: 1) The primary value of concern with respect to ultrasonic testing signal transmission is typically considered to be impedance. The nominal impedance of all three cable types used by ISwT is equal at 50 ohms.
: 2) Besides impedance, the next cable characteristic with potential to affect signal quality is the capacitance, which is related not only to the cross section of the conductors, but also to the design and spatial relationships between the core and the braid. Typically, signal loss increases as capacitance increases. Capacitance is expressed in values of pico-farads per foot. The RG-58 and RG-174 cable types used by ISwT have the same capacitance at 30.8 pF/ft. The smaller micro cable used at the AIRIS tool is a special design with a capacitance value of approximately 27 pF/ft. So in this case, the smaller cable has even less capacitance than the larger diameter RG-58 and RG-174 cables.
Using these values, the total capacitance of the cable configuration used for ISwT's PDI qualification (excluding connectors) is approximately 32,500 pF. The total capacitance of the AIRIS cable configuration for the DAEC examinations (excluding connectors) is approximately 5,600 pF. Based on these calculations it can be seen that the shorter lengths of cable used in the AIRIS configuration have less total capacitance than the cable configuration used for the qualification activity.
: 3) Another value that can influence signal amplitude is DC resistance. Increases in resistance can reduce signal amplitude. The resistance value for RG174 is 97 ohms per 1000 feet and the resistance value for RG58 is 10.8 ohms per 1000 feet. Therefore an approximation of the total resistance for the original cable configuration (1018' RG58 plus 80' RG174, excluding connectors) is 18.76 ohms. The approximate resistance of the typical AIRIS cable configuration (230' RG174, excluding connectors) is 22.31 ohms plus the value of the 5' of micro cable for which nominal resistance values are not available, but are considered insignificant due to the short length used.
One of the features of the ISwT procedures is that system gain is established based upon material noise in the examination component. Therefore, differences in cable configuration (within practical limits) are compensated when adjusting the total system gain on the component.
Based on this evaluation, ISwT was confident that the differences in cable type would have no adverse affect on the procedure performance.

Attachment 3 ISwT System Equivalency Demonstration After consulting with various technical experts and ASME personnel involved with the development of Appendix VIII, ISwT elected to also perform a system equivalency comparison using guidance from Appendix VIII, Supplement 1. ISwT's comparison test was generally compliant with Supplement 1, however a standard UT reference block was used in lieu of the recommended 'glass block' and a contact setup was used in lieu of the immersion test setup.
Essentially a full system setup and calibration was performed in accordance with procedure requirements with the addition of a spectrum analyzer to measure system output. A reference signal appropriate for each transducer type was obtained using the UT reference block and frequency/bandwidth measurements were obtained for each transducer/cable combination. No changes in system configuration were allowed, except for the cable configurations selected for comparison.
The Supplement I equivalency comparison was incorporated into Appendix VIII for the purpose of allowing procedure modifications without procedure re-qualification as long as the examination system performance is shown to be equivalent. Based on a variety of studies, center frequency and bandwidth have been shown to be valid measurements of system performance, primarily relying on the fact that flaw detection capability is largely dependent on frequency.
The results of this comparison showed that the total system performance was within established Appendix VIII equivalency guidelines of +/- 10% for center frequency and bandwidth for systems with bandwidths equal to or greater than 30%.

Attachment 4 ISwT Empirical Cable Comparison at DAEC While onsite at DAEC, ISwT conducted an empirical ultrasonic cable comparison using the entire system in an effort to establish equivalency between the three cable configurations:
a) The cable configuration to be used for DAEC RFO20, (230' RG 174) b) The cable configuration used for DAEC RFOI9, (230' RG174, 5'micro cable), and c) The original cable configuration used for procedure qualification in 1995 (1018' RG58, 80' RG174).
This comparison was performed for both types of search units (SLIC40 and Duplex55) with each cable configuration using the same calibration block reflector for each measurement. The key measurement parameter recorded was the system gain required to bring the calibration reflector to 80% of full screen height with the three different cable configurations.
The table below summarizes those measurements and indicates that:
: 1) In each case, less gain was required to bring the signals to 80% of full screen height when using either of the two shorter cable configurations than was needed with the longer cable configuration, indicating that signal amplitude is slightly higher when using the shorter BWR cable configurations
: 2) The differences between the cable configurations used for RFOI 9 and RFO20 are less than I dB, indicating that the micro cable has a negligible affect on the signal
: 3) There is less than 2dB difference between any of the cable configurations, indicating that the differences are not only within standard ultrasonic amplitude calibration tolerances, but that cable configuration differences are not significant when using the ISwT system.

It should be noted that 4 cable configurations are referenced in these records. Upon review of the initial records a discrepancy in the conduct of the test was noted for cable configuration 3, so the configuration was corrected and the measurements were repeated and noted on separate data sheets as cable configuration 4.
Both 3 & 4 consisted of the same original cable length, but the sequence of the cables was not correct for configuration 3.
Data acquisition system printouts are also included to document this comparison for configurations 1, 2, & 4. From these printouts, A-scan presentations indicate reasonable consistency in signal to noise ratio for each of the three cable configurations
