(Page 5 of 6) 5.0 BURDEN CAUSED BY COMPLIANCE Due to the component configuration, portions of the code required examination volume could not be completely examined. The curvature of the radius of the nozzle forging is such that ultrasonic scanning of the weld is interrupted due to loss of contact of the ultrasonic search unit. This limitation affects both transverse and parallel scanning of the code required examination volume.

In addition to component configuration, certain weld examinations are further limited by reactor pressure vessel design obstructions such as reactor pressure vessel appurtenances, bio-shield opening limitations, Outer Diameter (OD) contours, and mirror insulation. Examination coverage percentages are identified in Table R-44, and inspections were performed to the maximum extent practical for the given configuration.

The inspection results for the full penetration reactor vessel welds, nozzle to vessel welds, nozzle inside radius, and dissimilar metal welds in nozzles did not identify any unacceptable indications.

Oyster Creek Nuclear Generating Station requests relief from 100% volumetric examination of the full penetration reactor vessel welds, nozzle to vessel welds, nozzle inside radius and dissimilar metal welds in nozzles due to access limitations imposed by reactor pressure vessel design and/or component configuration.

6.0 PROPOSED ALTERNATIVE AND BASIS FOR USE No alternate provisions are practical for the subject welds. Examinations were performed to the maximum extent practical with the best available methods at the time of the examination.

7.0 DURATION OF PROPOSED ALTERNATIVE This relief is requested for the fourth 10-year ISI interval for Oyster Creek Nuclear Generating Station, which ended on January 14, 2013.

Description:

Limited Code Coverage on Piping Weld Examinations Component Number: See Table R-45 2.0 APPLICABLE CODE EDITION AND ADDENDA The fourth 10-year Inservice Inspection (ISI) interval program was based on the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel (B&PV)

Code,Section XI, 1995 Edition with 1996 Addenda.

3.0 APPLICABLE CODE REQUIREMENT ASME Section Xl, 1995 Edition with 1996 Addenda, required 100% volumetric examination of Class 1 and 2 welds as defined by Table IWB-2500-1 and Table IWC-2500-1.

4.0 IMPRACTICALITY OF COMPLIANCE Pursuant to 10 CFR 50.55a(g)(5)(iii), relief is requested from the 100% volumetric examination requirements of Class 1 and 2 welds as defined by Table IWB-2500-1 and Table IWC-2500-1 for the welds specified in Table R-45, "Limited Weld Coverage," on the basis that conformance with these Code requirements is impractical due to component configuration and access restrictions.

(Page 6 of 6) 5.0 BURDEN CAUSED BY COMPLIANCE The required ASME Code coverage is impractical for the subject welds since the components would require design modification that would impose a significant burden to Exelon Generation Company, LLC. At Oyster Creek Nuclear Generating Station, qualified PDI ultrasonic examination techniques have been used as required. There are no single sided examination procedures available for examination of austenitic piping welds and there are no qualified procedures for examination of cast materials; therefore, many welds may only be examined for 50% of the required examination volume. Other limitations are due to plant design/condition that would require changes to the plant installed condition to allow greater coverage.

The inspection results for the limited weld examinations listed in Table R-45 did not identify any unacceptable indications.

6.0 PROPOSED ALTERNATIVE AND BASIS FOR USE No alternate provisions are practical for the subject welds. Examinations were performed to the maximum extent practical with the best available methods at the time of the examination.

7.0 DURATION OF PROPOSED ALTERNATIVE This relief is requested for the fourth 10-year ISI interval for the Oyster Creek Nuclear Generating Station, which ended on January 14, 2013.

8.0 PRECEDENTS Similar relief requests have been approved for:

1) The Creek Nuclear Generating Station (OC-35), in U.S. Nuclear Regulatory Commission Safety Evaluation Report dated February 2, 2005.

2) The Limerick Generating Station, Units 1 and 2 (Relief Request RR-35) in a U.S. Nuclear Regulatory Commission Safety Evaluation Report dated January 27, 2009.

3) The Peach Bottom Atomic Power Station, Units 2 and 3 (Relief Request 13R-49) in a U.S.

Nuclear Regulatory Commission Safety Evaluation Report dated August 27, 2010.
