All further refcrcnccs to Oconee in this document are understood to include Oconee Units 1, 2, & 3 and Keowee Units I & 2. All pressure retaining components classified as ISI Class 1, 2, and 3 have been reviewed to detennine the applicable inservice inspection pressure test examination requirements per ASME Section XI.Based a fifth interval start date of July 15, 2014 for Oconee and the requirements of IOCFR50.55a(g)(4)(ii), inservice inspection pressure testing activities for Oconee shall be performed in accordance with the 2007 Edition of ASME Section XI with the 2008 Addenda, as modified by the Code Cases and Relief Requests included in this Pressure Testing Plan.When performing system leakage tests in accordance with IWA-5213(a), no holding time is required after attaining test pressure for Class 1 components, a 10-minute holding time after attaining test pressure is required for Class 2 and Class 3 components that are not required to operate during norual operating conditions, and no hold time is required for the remaining Class 2 and Class 3 components provided that the system has been in operation for at least 4 hours for insulated components or 10 minhutes for uninsulated components.
If leakage is detected on any of the Decay Heat Removal Coolers (IA, 2A, 3A: IB, 2B or 3B) during Pressure Testing and VT-2 examinations, the ISI NiDE Plan manager for Oconee shall be notified of the leakage so that an evaluation can be performed to determine the continued use of Code Case N-706-1 for IS] Database Smmnary Numbers within Category C-A.. Itcm No. C1.10 and Category C-B, Item No. C2.32.The following Code Cases apply to the Pressure Testing Program at Oconee: NRC Conditions for Use of Code Case Case No. Case Title Applicability (as stated in Regulatory Guide 1.147 Revision 16)N-706-1 Alternative Examination From the 1977 Unconditional Requirements to Table IWB- Edition up to and 2500-1 and Table IWC-2500-including the I for PWR Stainless Steel 2010 Edition Residual and Regenerative Heat Exchangers N-731 Alternative Class I System From the 1989 Unconditional Leakage Test Pressure Edition tip to and Requirements including tihe 2010 Edition with tie 2011 Addenda 2 Inspection Methods and ProcIedures to be Used for Inscrvice Inspection Pressure Testing VT-2 visual examinations shall be conducted to locate evidence of leakage from pressure retaining components during tie conduct of a system pressure test, except for buried components.

Changes to the examination boundaries will be shown on the latest ISI Pressure Testing Boundary Drawing revision in NEDL.Section XI requirements for the boundaries of System Pressure Testing are included in IWB-5222, IWC-5222 and IWD-5222 and are refelcted on the ISI Pressure Te'sting Boundary Drawings.Duke Energy Oconee Nuclear Station Fifth Interval Inservice Inspection Pressure Test Plan Revision 0 Page 6 of 10 7 Components Exempted or Excluded From Section XI System Pressure Testing Components exempted or excluded from Section XI Pressure Testing requirments are listed in IWA-5 110, IWC-5222 and IWD-5222.
Specific application of these exemptions and exclusions are shown on the ISI Pressure Testing Boundary drawings, which are described in Section 11 of this document and listed in Attachments A, B and C. The following are examples of pressure test cxemptions and exclusions:
* Non pressure retaining portions of the Reactor Coolant Pumps.* Open ended portions of IS] Class 2 and 3 discharge piping per lWC-5222(b) mid JWD-5222(b), however, this does not apply to repair/replacement activities related to pressure testing.* ISI Class 2 and ISI Class 3 portions of systems that do not support tie system safety function beyond the first nornally closed valve (including relief valves or valves capable of automatic closure) per IWC-5222(b) and IWD-5222(b).
* Containment penetrations where the piping and isolation valves perform a containment function and rte balance of the piping system is outside the scope of Section XI per IWA-51 10(c).* Systemns/components determined to be optionally owncr classi fled as ISI Class 2 or ISI Class 3 per Section X1, IWA-1 320(e).* Containment sump suction piping.8 Section XI System Pressure Testing Scheduling Section XI System Pressure Testing is scheduled in accordance with requirements of the Section XI Tables for Categorics B-P, C-H and D-B. Note that the Section XI scheduling requirements in IWB-241 1, IWC-241 I and IWD-2411 do not apply to Categories B-P, C-H and D-B.Section XI System Pressure Testing of ISI Class I systems and components shall be completed each refueling outage per Table IWB-2500-1, Category B-P. ISI Class I Pressure Testing is not scheduled on a period basis because the examinations are required to be completed each refueling outage.Section XI System Pressure Testing of ISI Class 2 and 3 systems and components shall be completed once each inspection period per Table IWC-2500-1, Category C-H and Table IWD-2500-1, Category D-B. ISI Class 2 and 3 Pressure Testing is not scheduled on an outagc-by-outagc basis because the examinations are required to be 100 percent complete by the end of the inspection period rather than a mninimnun/maximmun percentage each inspection period.

Typically, an Examination Zone terminates at a boundary valve, building interface, or component interface and may include components shown on several boundary drawings.
The Examination Zone includes all pressure retaining components within the scope of the boundary valves/extremity interfaces.
All Oconee Examination Zone numbers have the same format. The following example is for an ISI Class 1 System Leakage Test zone: OZXL-1-Sequential Number I (L) = Leakage Test (X) = Unit 1, 2, OR 3 (7% = "7nna"'-I (0) = Outage, (I) = Innage, or (K) = Keowee I Pressure Testing Examination Zone Report I A listing of the Pressure Testing zone numbers, examination frequency, and associated inspection information is shown on Attachments A, B, and C.Duke Energy Oconee Nuclear Station Fifth Interval Inservice Inspection Pressure Test Plan Revision 0 Page 9 of 10 11 System, Boundar i)rawing, and ISI Classification Listing]lie ISI Pressure Testing Boundary Drawings discussed in Section 6 of this document are based on the Reference Flow Diagrams listed in bottom left hand corner of the Boundary Drawings.
During the 5 h Interval: "As Built" Flow Diagram revisions will be reviewed to see if dic included changes have any impact on the 1SI pressure testing boundaries and the Flow Diagram revisions will be incorporated into the Inservice Inspection Pressure Testing Boundary drawings as necessary.
Some flow diagram revisions do not affect the pressure testing boundaries; therefore, the pressure testing boundary drawings are not required to be revised. For this reason, there may be a difference between the numeric revision level listed on the Flow Diagram versus the revision level of the Flow Diagram referenced on the ISI Pressure Testing Boundary Drawings.
The latest revision of the pressure testing boundary drawing can be retrieved from Nuclear Electronic Document Library (NEDL).See Attachment E for a listing of the pressure testing boundary drawings applicable to Occonee 1, 2, & 3 and Kcowec.12 Buried Components Unless otherwise specified, pressure testing for IS] classified buried components will be perfonued in accordance with ASME Section XI, IWA-5244.
Oconee will follow the IWA-5244 requirements for components embedded in concrete associated with the discharge of CCW Pumps I A, 11B, IC, ID, 2A, 2B, 2C, 2D, 3A, 3B, 3C, and 3D (see Zones OZIL-66, 07_21--66 and OZ3L-66 on Q-ISIL5-133A-1.1, O-ISIL5-133A-2.1, 1and O-ISILS-133A-3.1, respectively) for the 5h 10-Year Interval.
Oconee will perfonn an unimpaired flow tcst per procedures PT/I1-3/AJ0251/073.
The permanent test record must confirm the unimpaired flow tcst, per procedures PT/1-3/A/0251/073, was an acceptable test.Duke Energy Oconee Nuclear Station Fifth Interval Inservice Inspection Pressure Test Plan Revision 0 Page 10 ofl0 Attachment A The following pages are the Oconee Unit I -5lh 10-Year Interval Pressure Testing Examination Zone Report generated from the Pressure Test Database Management System (PTDMS).Duke Energy Oconee Nuclear Station Fifth Interval Inservice Inspection Pressure Test Plan Cover Page Revision 0 Altachment A
