SUMMARY

DESCRIPTION The proposed amendment would revise the Oconee Nuclear Station (ONS) Units 1, 2, and 3 Technical Specifications (TS) Administrative Controls Inservice Testing Program (i.e., TS 5.5.9) and references in the TS Bases (TSB) to reflect the current edition of the American Society of Mechanical Engineers (ASME) Code that is referenced in 10 CFR 50.55a(b).

U. S. Nuclear Regulatory Commission (NRC) regulations require the Inservice Testing Program (ITP) at nuclear power plants to be revised every 120 months to comply with the latest edition and addenda of the Code incorporated by reference in 10 CFR 50.55a(b).

The adoption of the latest edition renders select statements in the TS Administrative Controls ITP description and in the TSB incorrect.

These changes are consistent with NRC-approved Technical Specification Task Force (TSTF) Improved Standard Technical Specification Change Travelers TSTF-479, "Changes to Reflect Revision of 10 CFR 50.55a," (Ref. 1) and TSTF-497, "Limit Inservice Testing Program SR 3.0.2 Application to Frequencies of 2 Years or Less" (Ref. 2).In addition, the proposed amendment corrects an identified typographical error in TS 5.5.8,"Reactor Coolant Pump Flywheel Inspection Program." A detailed description of the proposed changes is provided in Section 3. A technical analysis of the proposed changes is provided in Section 4. The marked-up TS and TS Bases pages associated with this license amendment request (LAR) are provided in Attachments 1 and 2, respectively, and the retyped (clean) TS and TSB pages are provided in Attachments 3 and 4, respectively.

Once this LAR is approved, the amendment will be implemented within 120 days. There are no new regulatory commitments being made as a result of this proposed change.2 BACKGROUND In 1990, the ASME published the initial edition of the ASME Operation and Maintenance (OM) Code which gives rules for inservice testing of pumps and valves at nuclear power plants. The ASME intended that the ASME OM Code replace Section XI of the ASME Boiler and Pressure Vessel (B&PV) Code for inservice testing of pumps and valves. The 1995 edition of the ASME OM Code was incorporated by reference into 10 CFR 50.55a on September 22, 1999 (Ref. 3). Since 10 CFR 50.55a(f)(4)(ii) requires that inservice testing comply with the requirements of the latest edition and addenda of the ASME Code incorporated into 10 CFR 50.55a(b), TS 5.5.9 must be revised to reference the ASME OM Code. TSTF-479 was developed to provide licensees a standard method to request NRC approval of this required TS revision.

The NRC approved TSTF-479, as an administrative change to the Improved Standard Technical Specifications (ISTS) NUREGs, in a letter dated December 6, 2005 (Ref. 4).Although the NRC approved TSTF-479, the NRC expressed concerns with the TSTF changes to paragraph b of the ITP TS in a February 23, 2006 meeting with the TSTF Group.Specifically, the NRC felt that TSTF-479 did not provide adequate justification for applying Surveillance Requirement (SR) 3.0.2 to Frequencies specified in the ITP as greater than two years. Thus, the TSTF Group developed TSTF-497 to revise paragraph b of the ITP TS to Enclosure

-Evaluation of Proposed Changes License Amendment Request No. 2013-04 Page 2 of 9 specify the provisions of SR 3.0.2 are applicable to Inservice Testing Frequencies specified as two years or less. The NRC approved TSTF-497 in a letter dated October 4, 2006 (Ref.5).3 DESCRIPTION OF PROPOSED CHANGES Duke Energy proposes to modify the TS and TSB (for information only). The proposed change to ONS TS 5.5.8 only corrects a typographical error. The proposed changes to ONS TS 5.5.9, and in the TSB, will replace reference to ASME B&PV Code with reference to ASME OM Code for pump and valve testing only.

4 TECHNICAL ANALYSIS The purposes of the ONS ITP are to assess the operational readiness of pumps and valves, to detect degradation that might affect component OPERABILITY, and to maintain safety margins with provisions for increased surveillance and corrective action. NRC regulation 10 CFR 50.55a defines the requirements for applying industry codes to each licensed nuclear powered facility.

Licensees are required by 10 CFR 50.55a(f)(4)(i) to initially prepare programs to perform inservice testing of certain ASME Section III, Code Class 1, 2, and 3 pumps and valves during the initial 120-month interval of unit operation.

NRC regulation 10 CFR 50.55a(f)(4)(ii) requires that the ITP be revised during successive 120-month intervals of unit operation to comply with the latest edition and addenda of the Code incorporated by reference in paragraph (b) 12 months prior to the start of the interval.Section Xl of the ASME Codes has been revised on a continuing basis over the years to provide updated requirements for the inservice inspection and inservice testing of components.

Until 1990, the ASME Code requirements addressing the inservice testing of pumps and valves were contained in Section Xl, Subsections IWP (for pumps) and IWV (for valves). In 1990, the ASME published the initial edition of the OM Code that provides the rules for inservice testing of pumps and valves. Since the establishment of the 1990 Edition of the OM Code, the rules for inservice testing of pumps are no longer being updated in Section XI. As identified in NRC SECY-99-017, dated January 13, 1999 (Ref. 6), the NRC has generally considered the evolution of the ASME Code to result in a net improvement in the measures for inspecting piping and components and for testing pumps and valves.The TS ITP is revised to indicate that the provisions of SR 3.0.2 are applicable to other Inservice Testing Frequencies, of two years or less, that are not specified in the ITP. The ITP may have Frequencies for testing that are based on risk and do not conform to the standard testing Frequencies specified in the TS. For example, an ITP may use ASME Code Case OMN-1, "Alternative Rules for Preservice and Inservice Testing of Certain Electric Motor-Operated Valve Assemblies in Light-Water Reactor Plants," in lieu of stroke time testing. The Frequency of the Surveillance may be determined through a mix of risk informed and performance based means in accordance with the ITP. This is consistent with the guidance in NUREG-1482, "Guidelines for Inservice Testing at Nuclear Power Plants" (Ref. 7), which indicates that the 25% extension of the interval specified in the Frequency would apply to increased frequencies the same way that it applies to regular frequencies.

If a test interval is specified in 10 CFR 50.55a, the TS SR 3.0.2 Bases indicates that the requirements of the regulation take precedence over the TS.

-Evaluation of Proposed Changes License Amendment Request No. 2013-04 Page 5 of 9 5 REGULATORY ANALYSIS 5.1 NO SIGNIFICANT HAZARDS CONSIDERATION Duke Energy Carolinas, LLC (Duke Energy), has evaluated the proposed changes to the Oconee Nuclear Station (ONS) Technical Specifications (TS) using the criteria in 10 CFR 50.92 and has determined that the proposed changes do not involve a significant hazards consideration.

An analysis of the issue of no significant hazards consideration is presented below: Description of Amendment Reauest The proposed amendment would correct a typographical error in TS 5.5.8, "Reactor Coolant Pump Flywheel Inspection Program," and revise TS 5.5.9, "Inservice Testing Program," to include testing frequencies applicable to the American Society of Mechanical Engineers (ASME) Operation and Maintenance (OM) Code instead of the ASME Boiler and Pressure Vessel (B&PV) Code,Section XI. Additionally, TS 5.5.9 would also be revised to indicate that there may be some non-standard Frequencies utilized in the Inservice Testing Program in which provisions of SR 3.0.2 are applicable.

As described below, Duke Energy concludes that the change does not meet any of the three criteria for a significant hazards consideration.

Basis for Proposed No Significant Hazards Consideration Determination As required by 10 CFR 50.91 (a), the Duke Energy analysis of the issue of no significant hazards consideration using the standards in 10 CFR 50.92 is presented below: 1. Does the Proposed Change Involve a Significant Increase in the Probability or Consequences of an Accident Previously Evaluated?

Response:

No The proposed change corrects a typographical error in TS 5.5.8, "Reactor Coolant Pump Flywheel Inspection Program," and revises TS 5.5.9, "Inservice Testing Program," for consistency with the requirements of 10 CFR 50.55a(f)(4) regarding the inservice testing of pumps and valves which are classified as ASME Code Class 1, Class 2 and Class 3. The proposed change incorporates revisions to the ASME Code that result in a net improvement in the measures for testing pumps and valves.The proposed change does not impact any accident initiators or analyzed events or assumed mitigation of accident or transient events. The proposed change does not involve the addition or removal of any equipment, or any design changes to the facility.

Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.

Enclosure

-Evaluation of Proposed Changes License Amendment Request No. 2013-04 Page 6 of 9 2. Does the Proposed Change Create the Possibility of a New or Different Kind of Accident from any Accident Previously Evaluated?

Response:

No The proposed change corrects a typographical error in TS 5.5.8, "Reactor Coolant Pump Flywheel Inspection Program," and revises TS 5.5.9, "Inservice Testing Program," for consistency with the requirements of 10 CFR 50.55a(f)(4) regarding the inservice testing of pumps and valves which are classified as ASME Code Class 1, Class 2 and Class 3. The proposed change incorporates revisions to the ASME Code that result in a net improvement in the measures for testing pumps and valves.The proposed change does not involve a modification to the physical configuration of the plant (i.e., no new equipment will be installed), nor does it involve a change in the methods governing normal plant operation.

The proposed change will not impose any new or different requirements or introduce a new accident initiator, accident precursor, or malfunction mechanism.

Additionally, there is no change in the types or increases in the amounts of any effluent that may be released offsite and there is no increase in individual or cumulative occupational exposure.

Therefore, the proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated.

3. Does the Proposed Change Involve a Significant Reduction in a Margin of Safety?Response:

No The proposed change corrects a typographical error in TS 5.5.8, "Reactor Coolant Pump Flywheel Inspection Program," and revises TS 5.5.9, "Inservice Testing Program," for consistency with the requirements of 10 CFR 50.55a(f)(4) regarding the inservice testing of pumps and valves which are classified as ASME Code Class 1, Class 2 and Class 3. The proposed change incorporates revisions to the ASME Code that result in a net improvement in the measures for testing pumps and valves. The safety function of the affected pumps and valves will be maintained.

Therefore, the proposed change does not involve a significant reduction in a margin of safety.Based upon the above analysis, Duke Energy concludes that the requested change does not involve a significant hazards consideration, as set forth in 10 CFR 50.92(c),"Issuance of Amendment."

Enclosure

-Evaluation of Proposed Changes License Amendment Request No. 2013-04 Page 7 of 9 5.2 APPLICABLE REGULATORY REQUIREMENTS/CRITERIA NRC regulation 10 CFR 50.55a defines the requirements for applying industry codes to each licensed nuclear powered facility.

Licensees are required by 10 CFR 50.55a(f)(4)(i) to initially prepare programs to perform inservice testing of certain ASME Section III, Code Class 1, 2, and 3 pumps and valves during the initial 120-month interval.

The regulations require that programs be developed utilizing the latest edition and addenda incorporated into paragraph (b) of 10 CFR 50.55a on the date 12 months prior to the date of issuance of the operating license subject to the limitations and modification identified in paragraph (b).The proposed changes do not:* Alter the design or function of any system;* Result in any changes in the qualifications of any component; or* Result in the reclassification of any component's status in the areas of shared, safety-related, independent, redundant, and physically or electrically separated.

In addition, this Technical Specification change will not reduce the leak-tightness of the containment.

As such, there are no changes being proposed such that compliance with the regulatory requirements of 10 CFR 50.55a would not be fulfilled.

Therefore, based on the considerations discussed above: 1) There is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner;2) Such activities will be conducted in compliance with the Commission's regulations; and 3) Issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.5.3 PRECEDENCE A review of the NRC's Agencywide Documents Access and Management System (ADAMS) for prior TSTF-479/-497 license amendments issued by the NRC to nuclear power plants resulted in the following documents of precedence.

APPLICABLE SAFETY ANALYSES All accident analyses in the UFSAR that require safety valve actuation assume operation of both pressurizer safety valves to limit increasing reactor coolant pressure.

The overpressure protection analysis is also based on operation of both safety valves and assumes that the valves open at the high range of the setting (2500 psig system design pressure plus 3%). These valves must accommodate pressurizer insurges that could occur during a startup, rod withdrawal, ejected rod, or loss of main feedwater.

The startup accident establishes the minimum safety valve capacity.

The startup accident is assumed to occur at < 15% power.Single failure of a safety valve is neither assumed in the accident analysis nor required to be addressed by the ASME Code. Compliance with this Specification is required to ensure that the accident analysis and design basis calculations remain valid.Pressurizer safety valves satisfy Criterion 3 of 10 CFR 50.36 (Ref. 3).LCO The two pressurizer safety valves are set to open at the RCS design pressure (2500 psig) and within the ASME specified tolerance to avoid exceeding the maximum RCS design pressure SL, to maintain accident analysis assumptions and to comply with ASME Code requirements.

The valves will be tested per ASME -requirements and retumed to service with as-left setpoints of 2500 ps +/- 1%. The upper and lower pressure tolerance limits are based on t requirements of the ASME Boiler and Pressure Vessel Code, Sectio Illl, Article 9, Summer 1967, which limit the rise in pressure within the v ssel which they protect, to 10%above the design pressure.

Inoperability of ne or both valves could result in exceeding the SL if a transient were to oc ur.\The consequences of exceeding the ASME pr ssure limit could include damage to one or more RCS components, incr ased leakage, or additional stress analysis being required prior to of reactor operation.

d n APPLICABILITY In MODES 1, 2, and portions of MODE 3 above th LTOP cut in temperature, OPERABILITY of two valves is require because the combined capacity is required to keep reactor coolan pressure below 110% of its design value during certain accidents.

Po ions of MODE 3 are conservatively included, although the listed accidents ay not require both safety valves for protection.

REQUIREMENTS Operating each required reactor building cooling train fan unit for_ 15 minutes ensures that all trains are OPERABLE and that all associated controls are functioning properly.

It also ensures that blockage, fan or motor failure, or excessive vibration can be detected for corrective action.The Surveillance Frequency is based on operating experience, equipment reliability, and plant risk and is controlled under the Surveillance Frequency Control Program.SR 3.6.5.3 Verifying that each required Reactor Building Spray pump's developed head at the flow test point is greater than or equal to the required developed head ensures that spray pump performance has not degraded during the cycle. Flow and differential pressure are normal tests of centrifugal pump performance required (iby Code (Ref. 4). Since the Reactor Building Spray Sys em pumps cannot be tested with flow through the spray headers, they are tested on recirculation flow. This test confirms one point on the pump design curve and is indicative of overall performance.

Such inservice tests confirm component OPERABILITY, trend performance, and may detect incipient failures by indicating abnormal performance.

The Frequency of this SR is in accordance with the Inservice Testing Program.SR 3.6.5.4 Verifying the containment heat removal capability provides assurance that the containment heat removal systems are capable of maintaining containment temperature below design limits following an accident.

The safety and relief valve tests are performed in accordance withANSI Code (Ref. 6) and include the following for MSRVs: a. Visual examination; Change to: b. Seat tightness determination; "ASME" c. Setpoint pressure determination (lift setting);Chan-ae to: "ASME Code" d. Compliance with owner's seat tightness criteria; and e Verification of the balancing device integrity on balanced valves.Thee equires the testing of all valves every 5 years, with a minimum o 20 of the valves tested every 24 months.This SR is modified by a Note that states the surveillance is only required to be performed in MODES 1 and 2. This note allows entry into and operation in MODE 3 prior to performing the SR, provided there is no evidence that the equipment is otherwise believed to be incapable of performing its function.

Also, the guidance in the TS Bases for SR 3.0.1 states that equipment may be considered OPERABLE following maintenance provided testing has been satisfactorily completed to the extent possible and the equipment is not otherwise believed to be incapable of performing its function.

This allows operation to proceed to a MODE or other specified condition where other necessary post maintenance tests can be completed.

For example, the mode change provisions described above specifically applies to scenarios where maintenance on MSRVs is performed below the mode of applicability for LCO 3.7.1, testing has been satisfactorily completed to the extent possible, and the equipment is believed capable of performing its function.

The mode change provisions permit entry into Mode 3 in order to test and adjust the set pressure, as necessary, to satisfy SR 3.7.1.1 prior to entry into Mode 2.The MSRVs may be either bench tested or tested in situ at hot conditions using an assist device to simulate lift pressure.

If the MSRVs are not tested at hot conditions, the lift setting pressure must be corrected to ambient conditions of the valve at operating temperature and pressure.OCONEE UNITS 1, 2, & 3 B 3.7.1-3 DAts ^ns..... D"T"D I ]

REQUIREMENTS Operating each required reactor building cooling train fan unit for>_ 15 minutes ensures that all trains are OPERABLE and that all associated controls are functioning properly.

It also ensures that blockage, fan or motor failure, or excessive vibration can be detected for corrective action.The Surveillance Frequency is based on operating experience, equipment reliability, and plant risk and is controlled under the Surveillance Frequency Control Program.SR 3.6.5.3 Verifying that each required Reactor Building Spray pump's developed head at the flow test point is greater than or equal to the required developed head ensures that spray pump performance has not degraded during the cycle. Flow and differential pressure are normal tests of centrifugal pump performance required by the ASME Code (Ref. 4). Since the Reactor Building Spray System pumps cannot be tested with flow through the spray headers, they are tested on recirculation flow. This test confirms one point on the pump design curve and is indicative of overall performance.

Such inservice tests confirm component OPERABILITY, trend performance, and may detect incipient failures by indicating abnormal performance.

The Frequency of this SR is in accordance with the Inservice Testing Program.SR 3.6.5.4 Verifying the containment heat removal capability provides assurance that the containment heat removal systems are capable of maintaining containment temperature below design limits following an accident.

This test verifies the heat removal capability of the Low Pressure Injection (LPI)Coolers and Reactor Building Cooling Units.

SURVEILLANCE SR 3.7.1.1 REQUIREMENTS This SR verifies the OPERABILITY of the MSRVs by the verification of MSRV lift setpoints in accordance with the Inservice Testing Program. The safety and relief valve tests are performed in accordance with ASME Code (Ref. 6) and include the following for MSRVs: a. Visual examination;

b. Seat tightness determination;
c. Setpoint pressure determination (lift setting);d. Compliance with owner's seat tightness criteria; and e. Verification of the balancing device integrity on balanced valves.The ASME Code requires the testing of all valves every 5 years, with a minimum of 20% of the valves tested every 24 months.This SR is modified by a Note that states the surveillance is only required to be performed in MODES I and 2. This note allows entry into and operation in MODE 3 prior to performing the SR, provided there is no evidence that the equipment is otherwise believed to be incapable of performing its function.

Also, the guidance in the TS Bases for SR 3.0.1 states that equipment may be considered OPERABLE following maintenance provided testing has been satisfactorily completed to the extent possible and the equipment is not otherwise believed to be incapable of performing its function.

This allows operation to proceed to a MODE or other specified condition where other necessary post maintenance tests can be completed.

For example, the mode change provisions described above specifically applies to scenarios where maintenance on MSRVs is performed below the mode of applicability for LCO 3.7.1, testing has been satisfactorily completed to the extent possible, and the equipment is believed capable of performing its function.

The mode change provisions permit entry into Mode 3 in order to test and adjust the set pressure, as necessary, to satisfy SR 3.7.1.1 prior to entry into Mode 2.The MSRVs may be either bench tested or tested in situ at hot conditions using an assist device to simulate lift pressure.

If the MSRVs are not tested at hot conditions, the lift setting pressure must be corrected to ambient conditions of the valve at operating temperature and pressure.OCONEE UNITS 1, 2, & 3 B 3.7.1-3 XX/XX/XX I MSRVs B 3.7.1 BASES (continued)

SURVEILLANCE REQUIREMENTS SR 3.7.3.1 This SR verifies that the closure time of each MFCV and SFCV is_< 25 seconds on an actual or simulated actuation signal. The 25 seconds includes a 10 second signal delay and 15 seconds for valve movement.The MFCV and SFCV closure time is assumed in the containment analyses.

This Surveillance is normally performed upon returning the unit to operation following a refueling outage. The MFCV and SFCV should not be tested at power since even a part stroke exercise increases the risk of a valve closure with the unit generating power. This is consistent with the ASME Code (Ref. 2) requirements during operation in MODES 1 and 2.This SR is modified by a Note that allows entry into and operation in MODE 3 prior to performing the SR.The Frequency for this SR is in accordance with the Inservice Testing Program.REFERENCES

SURVEILLANCE SR 3.7.5.1 REQUIREMENTS Verifying the correct alignment for manual, and non-automatic power operated valves in the EFW water and steam supply flow paths provides assurance that the proper flow paths exist for EFW operation.

This SR does not apply to valves that are locked, sealed, or otherwise secured in position, since those valves are verified to be in the correct position prior to locking, sealing, or securing.This SR also does not apply to valves that cannot be inadvertently misaligned, such as check valves. This Surveillance does not require any testing or valve manipulation; rather, it involves verification that those valves capable of potentially being mispositioned are in the correct position.The Surveillance Frequency is based on operating experience, equipment reliability, and plant risk and is controlled under the Surveillance Frequency Control Program.SR 3.7.5.2 Verifying that each EFW pump's developed head at the flow test point is greater than or equal to the required developed head ensures that EFW pump performance has not degraded below the acceptance criteria during the cycle. Flow and differential head are normal indications of pump performance required by the ASME Code (Ref. 3). Because it is undesirable to introduce cold EFW into the steam generators while they are operating, this test may be performed on a test flow path.This test confirms OPERABILITY, trends performance, and detects incipient failures by indicating abnormal performance.

Performance of inservice testing in the ASME Code (Ref. 3), at 3 month intervals, satisfies this requirement.

SR 3.7.5.3 This SR verifies that EFW can be delivered to the appropriate steam generator in the event of any accident or transient that generates an Emergency Feedwater System initiation signal by demonstrating that each automatic valve in the flow path actuates to its correct position on an actual or simulated actuation signal. This SR is not required for valves that are locked, sealed, or otherwise secured in position under administrative OCONEE UNITS 1, 2, & 3 B 3.7.5-6 XX/XXIXX IlOCONEE UNITS 1, 2, & 3 B 3.7.5-6 XX/XX/XX I EFW System B 3.7.5 BASES (continued)
