Enclosure 1 to NG-07-0809 Page 2 of 8 Response to Request for Additional Information (RAI) Related to the Relief Request for 3rd Period Limited Weld Examinations 2.1 Request for Relief, Examination Cateqorv B-D. Item B3.90. Full PenetrationWelded Nozzles in Vessels The licensee previously proposed an alternative, which was approved by Safety Evaluation Report (SER) dated October 6, 2004 (ADAMS accession number ML042380089), to use ASME Code Case N-613-1, which limits the examination volume of Examination Category B-D welds to the weld and 1/2-inch of adjacent base materialon each side, in lieu of the ASME Code-required examination volume of the weld and 1/2-T of adjacentbase material, where T is the vessel thickness. The current request for relief indicates that achieving greaterthan 90% (of the volume approved by the October 6, 2004 SER) could not be accomplished for the subject reactorpressure vessel (RPV) nozzle-to-vessel welds.

2.1.1 Please re-calculateand report the volumetric coverage(s) obtained for the subject Examination Category B-D nozzle-to-vessel welds with respect to ASME Code requirements, i.e., calculate the coverage when the volume requiredis the weld and 1/2-T of adjacent base material, where T is the vessel wall thickness.

FPL Energy Duane Arnold Response:

The following Table provides the recalculated percentages Component Number Recalculated Description Coverage MSC-D001 56.83% Main Steam Nozzle to Vessel Weld MSD-DO01 56.83% Main Steam Nozzle to Vessel Weld FWB-D001 56.71% Feedwater Nozzle to Vessel Weld FWC-DO01 56.71% Feedwater Nozzle to Vessel Weld FWD-DO01 56.71% Feedwater Nozzle to Vessel Weld RRG-DO01 53.73% Recirculation Riser Nozzle to Vessel Weld JPB-DO01 53.49% Jet Pump Instrumentation Nozzle to Vessel Weld LCA-DO01 50.72% Standby Liquid Control Nozzle to Vessel Weld VIB-DO01 57.45% Vessel Instrumentation Nozzle to Vessel Weld

Enclosure 1 to NG-07-0809 Page 3 of 8 2.1.2 The licensee stated that the subject nozzle-to-vessel welds are accessible from the vessel side of the RPV, but examinations cannot be performed from the nozzle side due to forging curvature. It is also stated that certain nozzle-to-vessel weld examinations are additionallylimited by RPV design obstructions. However, these statements do not provide adequate descriptive information and technical discussion to support a determination of impracticalityand that the requiredexaminations have been performed to the maximum extent possible at DAEC.

a. Provide a detailed description of examination limitations including access requirementsfor automatedor manual ultrasonic techniques employed, and a description of each component geometry that restricts or limits examinations. The technical bases should include cross-sectional sketches of the weld indicating ultrasoniccoverage(s) for each technique employed and details of the weld and base metal materials.

FPL Energy Duane Arnold Response:

The examination of all nozzle-to-vessel welds is limited by the nozzle forging curvature. The configuration for each of the above mentioned nozzles is included for review in Enclosure 2.

For nozzle LCA-D0O1, the examination is additionally limited by the proximity of the weld attaching the skirt knuckle to the RPV bottom head. The distance from the bottom of LCA-DO01 weld to the skirt is approximately six inches.

.For nozzle JPB-D001, the examination is additionally limited due to an insulation bracket welded on the vessel. Removal of this bracket is not feasible due to the fact that it supports the lower ring of RPV insulation.

b. In addition, the licensee should submit argument(s) as to why the use of other inspection methods (such as phased array ultrasonic testing) would not reasonably increase the examination coverage(s).

FPL Energy Duane Arnold Response:

As stated in Reference 1, the procedures used at DAEC incorporate examination techniques qualified under Appendix VIII of ASME Section XI Code by the Performance Demonstration Initiative (PDI) for examination of the nozzle-to-vessel shell welds. In addition, FPL Energy Duane Arnold contracted EPRI to computer model each nozzle-to-vessel weld and nozzle inner corner region to assist FPL Energy Duane Arnold in developing and qualifying ultrasonic techniques for these regions. At the time that these components were examined, the phased array technology had not been qualified by Performance Demonstration Initiative for examination of nozzle-

Enclosure 1 to NG-07-0809 Page 4 of 8 to-vessel welds or the nozzle inner corner region. With the computer modeling of the examination volume and the qualified PDI technique, the examinations were performed utilizing the latest technology.

2.1.3 State the total number of Examination Category B-D welds at DAEC, and provide a listing of the volumetric coverage(s) completed for each of these welds. Report any unacceptable flaws detected during the examination of the welds.

FPL Energy Duane Arnold Response:

The total number of Category B-D welds at the DAEC is 34 of which one is inaccessible due to the CRD array (the inaccessible nozzle is the bottom head drain). There have been no unacceptable flaws identified during the examinations of the listed welds. FPL Energy Duane Arnold has submitted three relief requests with Safety Evaluation Reports (SERs) dated October 18, 1999, March 7, 2001, and March 26, 2003. Below is a table with the accumulated percentages of nozzle to vessel welds from the above SERs.

  • Due to the nozzle design it is not feasible to effectively exam 100% of the required code volume as defined in Figure IWB-2500-7(b).

Enclosure 1 to NG-07-0809 Page 5 of 8 2.2 Request for Relief, Examination Category B-D, Item B3. 100, Inner Radius Sections of Full PenetrationWelded Nozzles in Vessels 2.2.1 The licensee stated that the proximity of the RPV skirt weld obstructed access for performing the inner radiussection examination on Standby Liquid Control Nozzle LCA-DOO1. However, this statement does not provide adequate descriptive information and technical discussion to support a determinationof impracticalityand that the required examination was performed to the maximum extent possible at DAEC.

a. Provide a detailed description of examination limitations including access requirements for automated or manual ultrasonictechniques employed, and a description of the component geometry that restricts or limits the examination. The technical basis should include cross-sectional sketches of the inner radius section indicating ultrasonic coverage for each technique employed.

FPL Energy Duane Arnold Response:

A description of examination limitations for performing the UT on the inner radius section on Standby Liquid Control Nozzle LCA-DO01 is included for review as Enclosure 3. The configuration of the nozzle and a photo indicating the proximity of the nozzle to the skirt is also included for review. The request for additional information included a request for cross sectional sketches of the inner radius section. Since the limitation is due to the skirt welded to the vessel and not the configuration as it was on the nozzle-to-vessel welds discussed above, a cross-sectional view is not warranted. To clarify, the skirt limits the surface contact area of the transducer.

The manual ultrasonic techniques employed were as recommended in the EPRI modeling Report IR-2004-62. The techniques utilized were limited by the proximity of the weld attaching the Skirt Knuckle to the RPV bottom head.

The supplied photo in Enclosure 3 shows that the nozzle is located close (approximately six inches) to the skirt weld.

b. In addition, the licensee should submit an argument as to why the use of other inspection methods (such as phased array ultrasonictesting) would not reasonablyincrease the examination coverage.

FPL Energy Duane Arnold Response:

Please refer to the Section 2.1.2 b response. FPL Energy Duane Arnold used the latest PDI demonstrated procedure for the examination of the listed welds at the DAEC.

Enclosure 1 to NG-07-0809 Page 6 of 8 2.3 Request for Relief, Examination Category B-J, Item B9. 11, Pressure Retaining Welds in Piping 2.3.1 The licensee stated that Weld RBB-JO01 is a branch connection of the recirculationbypass line to the recirculationdischarge line, and that the weldolet side is not accessible for scanning due to geometry. However, this statement does not provide adequate descriptive information and technical discussion to support a determination of impracticalityand that the required examination was performed to the maximum extent possible at DAEC.

a. Provide a detailed description of examination limitations including access requirements for automated or manual ultrasonic techniques employed, and a description of the component geometry that restricts or limits the examination. The technicalbasis should include cross-sectional sketches of the weld indicating ultrasoniccoverage for each technique employed.

FPL Energy Duane Arnold Response:

The weld RBB-JO01 is a branch connection of the recirculation bypass line to the recirculation discharge line. The weldolet side of the weld is not accessible for scanning. The PDI qualified procedure is NOT qualified for "detection or length sizing of circumferentially oriented flaw indications when only single side access is available and the flaw is located on the far side of the weld." Because of this, only 50% coverage can be claimed. The examination of this weld is further limited by the existing weld crown.

Included for review is Inservice Inspection Report 101070 in Enclosure 4.

b. State the size, thickness and materials of construction of the subject weld.

FPL Energy Duane Arnold Response:

The size of the weld is 4 inches, thickness 0.337 inches, and material is 304 stainless steel.

2.3.2 The licensee listed this weld as Examination Category B-J, Item B9.11, which is for circumferentialbutt welds, NPS 4-inch and larger. However, the licensee stated that Weld RBB-JO01 is a branch connection. Discuss why this weld is not listed as ASME Code Item B9.31 or B9.32.

Enclosure 1 to NG-07-0809 Page 7 of 8 FPL Energy Duane Arnold Response:

The weld is the first circumferential weld off of a weld-o-let connection.

Please refer to Enclosure 4 which illustrates the weld limitation.

2.3.3 State the total population of ASME Code Examination Category B-J welds of similarpipe diameterand wall thickness examined on the same recirculation loop at DAEC, and discuss the volumetric coverage(s) obtained for each of these welds.

FPL Energy Duane Arnold Response:

There are a total of nine welds on the same bypass line for Recirculation Loop B. Weld RBB-JO01 was the only weld selected for examination under the ISI Program (1989 Edition of ASME Section XI). For the implementation of Risked Informed ISI, these nine welds are categorized as Category 6a (5a with IGSCC). None of these welds were selected under the RI-ISI Program.

2.4 Request for Relief, Examination Cate-gory C-A, Item C1.20, Pressure Retaininq Welds in Vessels 2.4.1 The license stated that heat exchanger tie-down brackets obstruct access to the subject head-to-shell weld, limiting examination coverage. However, this statement does not provide adequate descriptive information and technical discussion to support a determination of impracticalityand that the required examination was performed to the maximum extent possible at DAEC.

a. Provide further text and/or a cross-sectionalsketch describing the basis for impracticalityand showing volumetric coverage for Weld HEA-CA-05. In addition, state or show the material, thicknesses, and outside diameters for the subject component. Discuss why the tie-down brackets cannot be removed to allow greateraccess.

FPL Energy Duane Arnold Response:

Please refer to the attached ISI Report 101098 page 54 of 56 (Enclosure 5) for location of the heat exchanger tie-down brackets that obstruct the head-to-shell weld on the Residual Heat Removal (RHR) Heat Exchanger (Weld HEA-CA-05), which limits the examination coverage. Also provided in Enclosure 5 are some photos showing typical welded attachments to the heat exchanger.

The original Form U-1 (Enclosure 6) is attached to identify material, thickness, and outside diameter of the RHR Heat Exchanger.

Enclosure 1 to NG-07-0809 Page 8 of 8

b. State whether the volumetric examination was performed with procedures and personnel that have been qualified in accordance with ASME Code, Section X1, Appendix VIII.

FPL Energy Duane Arnold Response:

The FPL Energy Duane Arnold Administrative Control Procedure that was utilized at the DAEC for the examination on Weld HEA-CA Head to shell weld on the RHR Heat Exchanger was ACP 1211.34, "Manual Ultrasonic Examination of Ferritic Welds < 2 inches Thickness." This procedure is in accordance with ASME Section XI, Appendix Ill.

2.4.1(1) State the total population of ASME Code Examination Category C-A welds at DAEC, and discuss the volumetric coverage(s) obtained for each of these welds.

FPL Energy Duane Arnold Response:

The DAEC has one category C-A Item C1.20 weld (HEA-CA-05) and two category C-A, Item C1.10 welds (HEA-CA-01 and HEA-CA-03). The following table provides the examination coverage of the three identified welds.
