i SECOND 10-YEAR INTERVAL REQUEST FOR RELIEF NO.98-001 Pursuant to 10CFR50.55a (g)(5)(iii), Duke Energy Corporation has determined that compliance with the specified requirements would result in hardship or unusual difficulty without a compensating increase in the level of quality and l
safety. Conformance with examination requirements of ASME Section XI is not practical for McGuire Nuclear Station Unit 1. Information is therefore being submitted in support of this determination and request is being sought for relief from the applicable ASME Section XI requirements (s).

The most effective ultrasonic technique for the examination of dissimilar metal welds uses refracted longitudinal waves. The longitudinal wave is preferred as the austenitic weld metal and buttering when present create highly attenuative barriers to shear wave ultrasound. The longitudinal wave is less affected by these difficulties. However, the longitudinal wave is affected by mode conversion when it strikes the inside surface of the safe end or pipe at any angle other than a right angle to the surface.
The calculations below shows that a 45 refracted longitudinal wave striking the inside surface of a pipe will produce a 22.9 refracted shear wave in addition to the normally expected 45 reflected longitudinal wave.
Sin ' = (sin 45 x V )+ Vt
= (0.707 x 0.123) + 0.223 d
Where:
sin is the shear wave angle V, is the shear wave velocity of the stainless steel safe end/ pipe material in inches / sec.
V.is the longitudinal wave velocity of the stainless steel safe / pipe end t
materialininches/ sec.
l As shown in the graph below, the mode conversion process creates two sound beams of differing intensities reflecting off of the inside surface.' At incident angles greater than 30 the shear wave will predominate. However, the shear wave is attenuated and scattered by the austenitic weld metal and the layer of buttering. The examina-tion sensitivity is degraded to such an extent that any examination using the second sound path leg is meaningless. Therefore, the two beam path direction coverage requirement is impractical.
In order to obtain the required two beam path direction coverage, welds would have l
to be re-designed to allow scanning from both sides.

Examination Category H-J continued i
In all cases of austenitic welds with single sided access, the stainless steel characteristics mandate the use of refracted longitudinal waves. This type of ultrasonic wave produces mode conversion at the pipe inside surface, thus l
preventing the use of sound path distances beyond the first " leg". Therefore, coverage of the required examination volume in two-beam path directions is not practical.
In order to obtain the required two beam path direction coverage, the branch connections and the elbow to pump weld would have to be re-designed to allow scanning from both sides of the weld.

Alternate Examinations or Testing:
t i
The use of radiography as an alternate volumetric examination for all the above listed components is not practical due to component thickness and geometric configurations. Other restrictions making radiography impractical are the physical barriers prohibiting access for placement of source, film, image quality indicator, etc.
Since radiography is impractical, Duke Energy Corporation will continue to use ultrasonic examination procedures to obtain maximum coverage to the extent practicable of the Item Numbers referenced in Section I of this Request for Relief. No additional ultrasonic examinations are planned during the current interval for the welds referenced in Section I of the request.
For the Class 1 Components listed in Section I above, Duke Energy proposes to use the pressure test to compliment the limited examination coverage. The Code requires (reference Table IWB-2500-1. Item Number B15.) that a system leakage test be performed after each refueling outage. Additionally a system hydrostatic test (reference Table IWB-2500-1, item Number B15.) is required once during each 10-year inspection interval. These tests require a VT-2 visual examination for evidence of leakage. This testing will provide adequate assurance of pressure boundary integrity.
i For the Class 2 Components listed in Section I above, Duke Energy proposes to i
use the pressure test to compliment the limited examination coverage. The Code requires (reference Table IWC-2500-1, Item Number C7.) that a system pressure test be performed once each period. Additionally a system hydrostatic test (reference Table IWB-2500-1, Item Number C7.) is required once during each 10-year inspection interval. These tests require a VT-2 visual examination for 1
evidence of leakage. This testing will provide adequate assurance of pressure boundary integrity.

1 Examination Cateaory B-A. Item B1.30. Pressure Retainina Welds in Reactor Vessel The Reactor Vessel Flange to Upper Shell Weld (IRPV7-442) (Item Number B01.030.001). This weld joins the reactor vessel flange to the upper shell (nozzle belt). The principal limitation for this weld is the stud holes for the i
__.. _.. _ _ _ - _ _ _ _ _. _ _ _ _ _ _ ~.
Serial No.98-001 Page 15 of 24 reactor head that limits the scanning area. Therefore, the 100% volumetric l
examination is impractical for this weld. The imposition of this requirement t
would create a considerable burden on Duke Energy Comoration. Reference i for scan coverage.
Although the examination volume requirements as defined in ASME Section XI i
1986 Edition, Figure IWB-2500-4 could not be met, the amount of coverage obtained for these examinations provides an acceptable level of quality and integrity.
i The Reactor Pressure Vessel (RPV) Flange to Upper Shell (Weld Number IRPV7-442) is by definition not in the beltline area of the RPV; therefore,it is not subject to Duence levels equal to or greater than i E7 n/cm2. RpV materials not in the highly irradiated beltline region are not prone to negative material propeny changes (i.e., embrittlement) associated with neutron bombardment.
Based upon 10 CFR 50.55a, the ASME Code Section XI 1986 Edition requires essentially 100% RPV weld volumetric examinations of beltline welds during every inspection interval. The RPV Flange to Upper Shell Weld does not meet the requirements of a beltline weld due to a significantly lower Buence exposure, resulting in far less potential degradation of ductility. The McGuire Nuclear Station Unit 1 RPV was fabricated by the Combustion Engineering Company and is free from unacceptable fabrication defects. Combustion Engineering performed rigorous state-of-the-art RPV inspections following fabrication to ensure no significant flaws existed.
The flange to upper shell configuration and location of the stud holes in the proximity of the RPV Flange to Upper Shell Weld prevents obtaining 100%
volumetric examination coverage; therefore, the 100% examinations are impractical. Elimination of the stud holes and/or ultrasonic examination from the inside surface of the head are not viable alternatives and would create an undue burden on Duke Energy Corporation.
Pursuant to 10 CFR 50.55a(g)(6)(i), granting this relief for the Reactor Vessel Flange to Upper Shell Weld will provide reasonable assurance of weld / component integrity, and is authorized by law. In addition, the requested relief will not endanger life or property or the common defense and security and is otherwise in the public interest giving due consideration to the burden upon the licensee that could result if the requirements were imposed on the facility.

IRPV5-445G (Item Numbers B03.090.007A), and 1RPV5-445H (Item Numbers B03.090.008A). The four Outlet Nozzle to Shell Welds were limited due to the reactor vessel nozzle configuration. Therefore, the 100% volumetric examination is impractical for this weld. The imposition of this requirement would create a considerable burden on Duke Energy Corporation. During the examination of these welds, techniques were utilized to obtain the maximum possible coverage. Reference drawing 1213930D (Attachment 2) for scan coserage.
The Reactor Vessel (Nozzle Inside Radius Sections) are:
1RPV5-445ER (Item Numbers B03.100.005),
l 1RPV5-445FR (Item Numbers B03.100.006),
1RPV5-445GR (Item Numbers B03.100.007), and IRPV5-445HR (Item Numbers B03.iOO.008). These four Outlet Nozzle Inner Radius Sections are limited due to the reactor vessel nozzle configuration.
Therefore, the 100% volumetric examination is impractical for this weld. The imposition of this requirement would create a considerable burden on Duke Energy Corporation. During the examination of these welds, techniques were utilized to obtain the maximum possible coverage. Reference drawing 1213930D (Attachment 2) for scan coverage.
The Pressurizer (Nozzle to Vessel Welds) are:
1PZR-12 (Item Number B03.110.002),
1PZR-15 (Item Number B03.110.005), and 1PZR-16 (Item Number B03.110.006). These three Pressurizer Nozzle to Upper Head Welds are limited due to single sided access caused by the nozzles geometry. In order to achieve more coverage, the nozzles would have to be redesigned to allow access from both sides. Therefore, the 100% volumetric examination is impractical for this weld. The imposition of this requirement would create a considerable burden on Duke Energy Corporation. During the examination of these welds, techniques were utilized to obtain the maximum possible coverage. Reference Attachment 3 for scan coverage.
The Pressurizer (Nozzle Inside Radius Sections) are:
1PZR-12R (Item Number B03.120.002),
1PZR-15R (Item Number B03.120.005), and 1PZR-16R (Item Number B03.120.006). These three Pressurizer Nozzle to Upper Head Welds (Inside Radius Sections) are limited due to the ratio of the nozzle O.D. to the vessel thickness. When the nozzle O.D. is large in relation to l
the vessel thickness,less coverage can be obtained when scanning from the vessel side. Therefore, the 100% volumetric examination is impractical for this weld. The imposition of this requirement would create a considerable burden on Duke Energy Corporation. During the examination of these welds, techniques
Serial No.931fqll Page 17 of 24 were utilized to obtain the maximum possible coverage. Reference Attachment 3 for scan coverage.
Although the examination volume requirements as defined in ASME Section XI 1986 Edition, Figure IWB-2500-7 could not be met, the amount of coverage obtained for these examinations provides an acceptable level of quality and integrity.
The Reactor Pressure Vessel (RPV) Outlet Nozzle to Shell Welds (Weld Numbers IRPV5-445E, IRPV5-445F, IRPV5-445G, IRPV5-445H, and Numbers IRPV5-445ER, IRPV5-445FR, IRPV5-445GR, IRPV5-445HR) are by definition not in the beltline area of the RPV; therefore,it is not subject to fluence levels equal to or greater than 1 E7 n/cm2. RPV materials not in the highly irradiated beltline region are not prone to negative material property changes (i.e., embrittlement) associated with neutron bombardment. Based upon 10 CFR 50.55a, the ASME Code Section XI 1986 Edition requires essentially 100% RPV weld volumetric examinations of beltline welds during every inspection interval. The RPV Outlet Nozzle Welds do not meet the 1
requirements of a beltline weld due to a significantly lower fluence exposure, resulting in farless potential degradation of ductility. The McGuire Nuclear Station Unit 1 RPV was fabricated by the Combustion Engineering Company and is free from unacceptable fabrication defects. Combustion Engineering performed rigorous state-of-the-art RPV inspections following fabrication to ensure no significant flaws existed.
The Pressurizer Nozzle to Upper Head Welds (Weld Numbers IPZR-12, IPZR-15, IPZR-16, and Numbers IPZR-12R, IPZR-15R, IPZR-16R) are located on the upper head of the pressurizer and are not part of the reactor pressure vessel.
These welds are not exposed to significant neutron fluence and are not prone to negative material property changes (i.e., embrittlement) associated with neutron bombardment. The McGuire Nuclear Station Unit 1 Pressurizer was fabricated i
by the Westinghouse and is free from unacceptable fabrication defects.
Westinghouse performed rigorous state-of-the-art inspections following fabrication to ensure no significant flaws existed.
The McGuire Unit 1 RPV Outlet Nozzle geometry and Pressurizer Nozzle to Upper Head Weld geometry prevents obtaining 100% volumetric examination coverage and the 100% examinations are impractical. Replacement or re-design of these nozzles is not a viable alternative and would create an undue burden on j
Duke Energy Corporation.

These four Dissimilar Metal Butt Welds are limited due to material i
l characteristics and single sided access caused by the component geometry j
prevents two beam path direction coverage of the examination volume. In order i
to obtain the required two beam path direction coverage, these four welds would j
have to be re-designed to allow scanning from both sides. The Steam Generator j
Nozzle to Safe End Butt Welds (Weld Numbers ISGD-INLET-SE and ISGD-OUTLET-SE) are located on the inlet and outlet of the steam generators for the reactor coolant piping. The McGuire Unit 1 Steam Generator Nozzle to Safe End Weld geometry prevented obtaining 100% volumetric examination coverage and therefore the 100% examinations are impractical. During the examination -
l of these welds, techniques were utilized to obtain the maximum possible coverage. Reference Attachment 4&5 for scan coverage.
Although the examination volume requirements as defined in ASME Section XI 1986 Edition, Figure IWB-2500-8 could not be met, the amount of coverage I
obtained for these examinations provided an acceptable level of quality and integrity. Furthermore, these welds wem cut-out and re-welded during the steam generator replacement (IEOCl1 outage). These new welds received a complete radiographic examination. There is no safety significance to the lack -

During the ultrasonic examination of the Reactor Coolant Pump 1 A to Pipe, Weld Number INCIF-1-6, (B09.011.006) shown in Attachment 6, coverage of the required examination volume was limited due to single sided access caused by the elbow to pump geomety which prevented scanning from both sides of the weld.
During the ultrasonic examination of the Nozzle to Elbow Weld, Number INCIF-1850, (B09.011.033) shown in Attachment 7, coverage of the required examination volume was limited because no scan could be performed from the nozzle side of the weld due to the nozzle transition.
During the ultrasonic examination of the Pipe to Elbow, Weld Number INCIF-539, (B09.011.036) shown in Attachment 8 coverage of the required examination volume was limited due to diametric shrinkage on the pipe side of j
