Committed to Nuclear Excellence Duane Arnold Energy Center Operated by Nuclear Management Company, LLC July 29, 2005 NG-05-0420 10 CFR 50.55a U.S. Nuclear Regulatory Commission ATTN: Document Control Desk Washington, DC 20555-0001 Duane Arnold Energy Center Docket 50-331 License No. DPR-49 Inservice Inspection Report In accordance with the requirements of Paragraph IWA-6230 of ASME, Section Xl, 1989 Edition/No Addenda and 10 CFR Section 50.55a(g), Nuclear Management Company, LLC (NMC) herewith submits the Refueling Outage (RFO) 19 Inservice Inspection Summary Report (Enclosure 1). This report addresses examinations that were performed at the Duane Arnold Energy Center (DAEC) during the time period from April 21, 2003 through May 3, 2005. Information regarding augmented inspections performed during RFO 19 is included in Enclosure 2. Enclosure 3 provides amended information from previously submitted RFO 17 and RFO 18 Summary Reports. These pages are being provided to correct minor errors that were identified on three pages of these reports.

As noted on Form NIS-1 included in the RFO 19 Summary Report, the third ten-year interval began on November 1, 1996 and will end on October 31, 2006. This end date has been changed from that shown on Form NIS-1 included with the RFO 18 Summary Report. The second ten year interval began on November 1, 1985 and had been previously extended in accordance with IWA-2430(d), resulting in an eleven year second interval. IWA-2430(d) states that interval adjustments shall not cause successive intervals to be altered by more than 1 year from the original pattern of intervals. Ending the third interval on October 3 2006 meets this requirement and is therefore allowed by IWA-2430.

Remarks:

Pilot Valves (S/N's 176. 199. 201, 207. 227) were removed during RFOI7 and sent to NWS Tech. for testing And refurbishment. During the refurbishment it was necessary to machine the pilot discs.

2'd stane discs and preload spacers for S/N's 176. 199. and 227. The pilot disc and 2tnd stage disc were machined on S/N 207.

PT exams were successfully performed on the machined surfaces for the above discs and spacers. The pilot disc and preload spacer were replaced on S/N 201. and preservice VT-3s were performed on the parts prior to shipping the items to NWS. The new 2n staye disc for S/N 201 was machined, and successful PT was performed on the machined surface. The preload spacer and the pilot stem were drilled and pinned together for SIN 201. After the above mentioned repairs, all five valve pilots were tested and found to have three successive tests that were acceptable.

Seal lines to I P216, HPCI main pump and I P21 6A. lPCI booster pump were rerouted for easier maintenan, This required two existing cyclone separator supports on I P216 to be ground off of the pump flange. and two larger supports were welded back onto the pump flange. The welds successfully passed surface exams. Also, welded two supports for cyclone separators on IP216A pump flange. Those welds successfully passed surface exams.

Machined area of pump flange to permit threading of a larger seal flush line fitting into the seal flange, This area was accessible for a surface exam. A PT exam was performed with no indications. Pressure testing was not required since the welding the supports onto the components did not penetrate through the pressure boundary of the components. as described in IWA4710.

Remarks:

Valve was disassembled an internal components were replaced. No pressure boundary components were replaced. Valve bonnet requires a seal weld to be removed and installed after disassembly and reassembly.

Surface exam was successfully completed on the body to bonnet seal weld. Pressure test was not necessary since IWA47 10 does not require pressure testine seal welds.

This work order reconligured the b pass line around the Drvwell purge I ne including a support change and changed a support on the Drvwell purge line. The current support design did not account for containment thermal growth. The bypass line run was cut out and welded, with one elbowv added. Surface exams were successfully performed on the welds. A support on the 2" bypass line was modified, a new u-bolt was installed that allowed for thermal movement. The new welds and fitting were pneumatically pressure tested successfully (P05053) A snubber (previously installed under PWOI 131078) was installed on the Drvwell pursue line.

Item Numbers B3.90, B3.100 There are a total of 34 nozzles, however I of the nozzles is exempt by IWB-1220(c) and not included in the percentages.

NOTE 2 -

Item Numbers B4.1 1, B4.12, B4.13 These items are required to be examined during conduct of the system hydrostatic test, IES Utilities has implemented Code Case N-498-1 (TAP-POIO)

NOTE 3 - Item Numbers B6.180, B6.190, B6.200, B7.50, B7.60,B7.70, B7.80, B12.50 These examinations are performed when the component is disassembled for other reasons. Therefore IWVX-2412-1 does not apply.

NOTE 4 - Item Numbers BI0.I0, B10.20, B10.30, C3.10, C3.20 These item numbers are from Code Case N509 (TAP-1004)

NOTE 5 - Item Number Fl.10, Fl.20, Fl.40 These item numbers are from Code Case N491 -I (TAP-1005)

NOTE 6 - Item Number B9.12 There are no welds counted for this item number because of the use of Code Case N-524 (NDE-R009)

NOTE 7 - Item Number B 1.30 50% of the shell-to-flange weld may be performed during the first and third inspection periods as allowed by Note 4 of Table IWB-2500-1.

NOTE 8 - Item Numbers B3.90, B3.100, B5.10 Relief Request NDE-R024 allows alternative percentages (ref. Code Case N-598). 2 of the Nozzle-to-safe-end welds (RRB-F002 and RRD-F002) have been repaired by applying a weld overlay.

These two welds are now covered by the requirements of BWRVIP-75.

NOTE 9 - Item Number E4.11 The DAEC has evaluated the need for augmented examination per this item number and has determined that the Torus should be examined twice per interval. Details are specified in Technical Approach and Position TAP-E002.

NOTE 10- Item Number E9.20 There are no components identified under this item number because the DAEC has been approved to use Option B of Appendix J. The "Performance Based Containment Testing Program" contains the requirements.

NOTE II - Item Numbers B5.XX, B9.XX, C5.XX, and R-I Risk-Informed methods are utilized as described in EPRI TR-I 12657B-A to determine scope of inspections for examination categories B-F, B-J, and C-F-2. The Risk-Informed scope has been combined into a new item number R-I for implementation in the second and third periods of the third interval.
