Dear Sir or Madam:
Attached for your review and approval are proposed Technical Specification (TS) changes revising the requirements associated with Arkansas Nuclear One, Unit 2 (ANO-2) provisions for containment building testing and inspection. The proposed changes affect ANO-2 TS Limiting Conditions for Operation (LCO), Surveillance Requirements, and applicable Bases relevant to inservice inspection requirements for the containment structures and tendons. Specifically, ANO-2 has implemented a containment inspection program which is in compliance with the requirements of 10 CFR 50.55a. The program is based on the American Society of Mechanical Engineers (ASME) Section Xl, Subsection IWL, as required by 10 CFR 50.55a(b)(2). Therefore, the proposed changes are being made to update the ANO-2 TSs to current requirements and format.
The proposed change has been evaluated in accordance with 10 CFR 50.91 (a)(1) using criteria in 10 CFR 50.92(c) and it has been determined that this change involves no significant hazards considerations. The bases for these determinations are included in Attachment 1. There are no commitments being made as a result of this request.
2CAN120401 Page 2 of 2 The proposed change is neither exigent nor emergency however; your prompt review is requested. We request NRC approval by August 31, 2004. Once approved, the amendment shall be implemented within 90 days. If you have any questions or require additional information, please contact Steve A Bennett at 479-858-4626.
I declare under penalty of perjury that the foregoing is true and correct. Executed on December 20, 2004.

Attachment I 2CAN1 20401 Analysis of Proposed Technical Specification Change to 2CAN120401 Page 1 of 6 Analysis of Proposed Technical Specification Change
1.0 DESCRIPTION
OF PROPOSED CHANGES The proposed change revises the Technical Specifications (TS) for Arkansas Nuclear One, Unit 2 (ANO-2). The proposed changes modify the Containment Structural Integrity specification (TS 3.6.1.5) to delete the existing Surveillance Requirements (SR) and add a new SR to verify containment structural integrity in accordance with the Containment Tendon Surveillance Program. A new Containment Tendon Surveillance Program requirement is being added to TS 6.5.6 and a new reporting requirement is being added to TS 6.6.6. The proposed changes are generally consistent with NUREG 1432, Standard Technical Specifications Combustion Engineering Plants, Revision 3.
2.0 PROPOSED CHANGE
The proposed changes to the Arkansas Nuclear One, Unit 2 TS are as follows:
- The Surveillance Requirement for TS 3.6.1.5 has been modified to delete the previous structural integrity Limiting Condition for Operation (LCO) requirement and to add a new LCO to ensure the structural integrity of the containment shall be OPERABLE. The Action statement is modified to be consistent with the LCO. The existing SRs are being replaced with a single SR which states: Verify containment structural integrity in accordance with the Containment Tendon Surveillance Program.
- An administrative change is being made to TS page 3/4 6-9a to renumber it as page 3/4 6-9.
- A new Containment Tendon Surveillance Program is being added as TS 6.5.6 which states:
This program provides controls for monitoring any tendon degradation in prestressed concrete containments, including effectiveness of its corrosion protection medium, to ensure containment structural integrity. The Containment Tendon Surveillance Program, inspection frequencies, and acceptance criteria shall be in accordance with the ASME Code, Section Xl, Subsection IWL and 10 CFR 50.55a. The provisions of SR 4.0.3 are applicable to the Containment Tendon Surveillance Program inspection frequencies.
This change meets the intent of TS 5.5.6 of NUREG-1432, Revision 3 but was modified as follows:
- 1. Regulatory Guide (RG) 1.35 is referenced in NUREG-1432, however, it has been superseded by 10 CFR 50.55a and ASME Code Section IWL for containment inspections. This is further discussed in Section 4.0 of this attachment.
- 2. The sentence regarding the program shall include baseline measurements prior to initial operations was deleted. This statement is no longer applicable to ANO-2 containment inspections.
- 3. The provisions of SR 4.0.2 being applicable are not being included in TS 5.5.6.
As discussed in the TS Bases of SR 3.0.2 of NUREG-1432, Revision 3, the requirements of regulations take precedence over the TSs. Therefore, SR 4.0.2 of the ANO-2 TSs is not applicable when referencing 10 CFR 50.55a as the inspection requirements.
to 2CAN120401 Page 2 of 6
- An administrative change is being made to TS 6.5.7 to move it to page 6-7.
- A new Containment Inspection Report is being added as TS 6.6.6 which states:
Any degradation exceeding the acceptance criteria of the containment structure detected during the tests required by the Containment Tendon Surveillance Program shall undergo an engineering evaluation within 60 days of the completion of the inspection surveillance. The results of the engineering evaluation shall be reported to the NRC within an additional 30 days of the time the evaluation is completed. The report shall include the cause of the condition that does not meet the acceptance criteria, the applicability of the conditions to the other unit, the acceptability of the concrete containment without repair of the item, whether or not repair or replacement is required and, if required, the extent, method, and completion date of necessary repairs, and the extent, nature, and frequency of additional examinations.
These reporting requirements are identical to those previously approved by the NRC in the ANO-1 Technical Specifications TS 5.6.6, Reactor Building Inspection Report.
The guidance in NUREG-1432, Revision 3, is enveloped in the ANO-1 TSs and the proposed ANO-2 TSs.
- The revised Bases to TS 4.6.1.5 are being modified to be consistent with NUREG-1432, Revision 3 except for the reference to RG 1.35. These Bases are being provided for information only.
3.0 BACKGROUND
10 CFR 50.55a(b)(2) requires licensees to implement the requirements of Subsection IWL of the ASME Code. The notice in the Federal Register (61 FR 413030) recognized that the final rule had satisfactorily considered the previous guidance provided in Regulatory Guide 1.35, Inservice Inspection of Ungrouted Tendons in Prestressed Concrete Containments, Revision 3.
ANO has established a Containment Inspection Program which includes both the tendon surveillance inspection requirements and the containment surface inspection requirements as required by Subsection IWL and 10 CFR 50.55a.
The containment building structure is discussed in the ANO-2 Safety Analysis Report (SAR)
Section 3.8.1.1. The containment consists of three basic parts: (1) a flat circular base slab, (2) a right circular cylinder, and (3) a sphere-torus dome. The containment is constructed of reinforced concrete prestressed by post-tensioned tendons in the cylinder and the dome.
Special reinforcing details are provided at discontinuities. The design of the containment is described more specifically in SAR Section 3.8.1.4.
The cylinder wall is prestressed by a system of horizontal and vertical tendons. The horizontal tendons are anchored at three buttresses equally spaced around the outside of the containment. The vertical tendons are anchored to the base slab at bottom and the ring girder at top. The dome is prestressed by three systems of dome tendons spaced at 120 degrees apart. The three-way dome tendons are anchored at the side of the ring girder. The tendons are installed in sheaths which are filled with a corrosion inhibitor. An access gallery is provided beneath the base slab for installation of the vertical tendons and inspection of bottom anchorage.
to 2CAN1 20401 Page 3 of 6 The interior of the containment is lined with steel plates welded together to form a leak tight barrier. Since the base slab liner plate is covered with concrete, leak chase channels are provided at seam welds, to allow for leak testing during normal operation.
4.0 TECHNICAL ANALYSIS
4.1 Removal of Existing ANO-2 TS 4.6.1.5 Surveillance Requirements The current Surveillance Requirement (SR) 4.6.1.5.1, Containment Tendons requires the visual examination of twenty-one tendons per specified interval. In addition, the SR requires the satisfactory completion of the examinations performed at the 1, 3, and 5 year interval and subsequent 5 year intervals. The requirements of Surveillance 4.6.1.5.1 have been superseded by the requirements contained in Subsection IWL and 10 CFR 50.55a and have therefore been deleted.
The requirements of Specification 4.6.1.5.2 have been superseded by the requirements contained in Subsection IWL of the ASME Code, 10 CFR 50.55a, and have therefore been deleted.
The requirements of Surveillance 4.6.1.5.3 are redundant to the requirements for a Containment Inspection as contained in 10 CFR 50, Appendix J. ANO-2 TS Section already requires compliance with the Containment Leakage Rate Testing Program contained in TS 6.15. Therefore, this SR is not required.
4.2 Containment Tendon Surveillance Program The portion of the ANO Containment Inservice Inspection Program which ensures the structural integrity of the containment through inspection of the tendon system is the ANO Containment Tendon Surveillance Program. Details of ANO Containment Inservice Inspection Program are provided in Entergy Procedure CEP-CI1-007, Arkansas Nuclear One Units I and 2 Containment Inservice Inspection (CII) Program Plan. Compliance with TS 6.5.6 will be performed by application of this program.
The Containment Tendon Surveillance Program, inspection frequencies, and acceptance criteria are currently in accordance with the 1992 Edition, 1992 Addenda of ASME Code, Section Xl, Subsection IWL and 10 CFR 50.55a. Entergy will update to later ASME Code Editions as required by 10 CFR 50.55a. However, Revision 3 of NUREG-1432 refers to a bracketed application of Regulatory Guide 1.35, Revision 1 for implementing a Containment Tendon Surveillance Program. Instead, Entergy is implementing the Containment Tendon Surveillance Program as an integral part of the Containment Inservice Inspection Program. This program is in compliance with the requirements of 10 CFR 50.55a(b)(2). The previous Containment Tendon Surveillance Program based on Regulatory Guide 1.35, Revision 1, has been superseded based on the issuance of Subsection IWL of the ASME Code.
Upon identification of any degradation reaching specific thresholds defined by Subsection IWL of the ASME Code, an Engineering Evaluation is required to determine the impact of the degradation on overall operability. If structural integrity cannot be established from the Engineering Evaluation, the Containment will be declared inoperable. By including to 2CAN120401 Page 4 of 6 structural integrity in Specification 3.6.1.5, the unit would be required to restore structural integrity (Operability) within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> or commence plant shutdown. Specification 3.6.1.5 currently allows a restoration period of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> before unit shutdown must commence.
The proposed change is, therefore, more restrictive and is generally consistent with that of NUREG-1432.
Containment Inspection Program Reporting The reporting requirements under TS 6.6.6 will require an Engineering Evaluation be submitted to the NRC within 30 days of completion for any degradation exceeding the acceptance criteria of the containment structure detected during the tests required by the Containment Tendon Surveillance Program. The report shall include the cause of the condition that does not meet the acceptance criteria, the applicability of the conditions to the other unit, the acceptability of the concrete containment without repair of the item, whether or not repair or replacement is required and, if required, the extent, method, and completion date of necessary repairs, and the extent, nature, and frequency of additional examinations.
This reporting requirement establishes the timing for submittal of the information required by IWL-331 0. This reporting requirement is also consistent with that contained in the ANO-1 Technical Specification 5.6.6 issued in ANO-1 License Amendment 199 (Ref. 1).
Even though the wording is the same as the current ANO-1 TSs, it includes the considerations of NUREG 1432.
Based on the above, Subsection IWL of the ASME Code and 10 CFR 50.55a(b)(2) adequately address testing of the containment structure. Incorporating current requirements, the elimination of redundant regulations, and implementing administrative improvements provide technical specifications that are more appropriate. Because existing requirements are controlled by regulation, there is no reduction in safety and adequate control is maintained. ANO-2 has determined that the controls governing the concrete containment inspection provided by the ANO Containment Inservice Inspection Program are adequate and are in keeping with the philosophy associated with the NUREG-1432, Revision 3.
5.0 REGULATORY ANALYSIS
5.1 Safety Analysis Report (SAR) Review ANO-2 SAR Section 3.8.1.7.3 Inservice Tendon Surveillance states:
The objective of the inservice tendon surveillance program during the lifetime of the plant is to provide a systematic means of assessing the continued quality of the post-tensioning system. The program is intended to furnish sufficient inservice historical evidence to provide a measure of confidence in the condition and the functional capability of the system, as well as an opportunity for timely corrective measures should adverse conditions, such as excessive corrosion, be detected. The inservice tendon surveillance program will be conducted in accordance with the requirements of ASME B&PV Code Section Xl Subsection IWL as modified by 10 CFR 50.55a.
This statement represents required compliance with ASME B&PV Code Section Xl Subsection IWL and is consistent with the proposed changes in Attachment 2 to this submittal.
i.
Attachment 1 to 2CAN120401 Page 5 of 6 General Design Criterion 53, Provisions for Containment Testing and Inspection, requires that the reactor containment shall be designed to permit (1) appropriate periodic inspection of all important areas, such as penetrations, (2) an appropriate surveillance program, and (3) periodic testing at containment design pressure of the leak tightness of penetrations which have resilient seals and expansion bellows. Entergy assures that the ANO-2 containment retains its ability to retain design basis pressure by the application of the ANO Containment Tendon Surveillance Program being required by 10 CFR 50.55a and the proposed TS.
5.2 Determination of No Significant Hazards Consideration Entergy Operations, Inc. is proposing that the Arkansas Nuclear One Unit 2 (ANO-2)
Operating License be amended to revise the requirements for ensuring containment structural integrity. The proposed changes modify the Containment Structural Integrity Technical Specification (TS) 3.6.1.5 to delete the existing Surveillance Requirements (SR) and add a new SR to verify containment structural integrity in accordance with the Containment Tendon Surveillance Program. A new Containment Tendon Surveillance Program is added to TS 6.5.6 and a new reporting requirement is being added to TS 6.6.6. The proposed changes are generally consistent with NUREG 1432, Standard Technical Specifications Combustion Engineering Plants, Revision 3.
An evaluation of the proposed change has been performed in accordance with 10 CFR 50.91(a)(1) regarding no significant hazards considerations using the standards in 10 CFR 50.92(c). A discussion of these standards as they relate to this amendment request follows:
Criterion 1 - Does Not Involve a Significant Increase in the Probability or Consequences of an Accident Previously Evaluated.
The containment building is not considered to be the initiator of any accident previously evaluated, but serves to mitigate accidents that could allow a release to the environment. The proposed TS change will provide for containment tendon inspections as required by 10 CFR 50.55a and prevent or inhibit release from the containment building as designed. Through appropriate inspections and implementation of corrective actions for any degradation discovered during the inspections that might lead to containment structural failures, the probability or consequences of accidents will not be increased.
Therefore, the removal of inspection details from the TS does not involve a significant increase in the probability or consequences of any accident previously evaluated.
Criterion 2 - Does Not Create the Possibility of a New or Different Kind of Accident from any Previously Evaluated.
The proposed change does not change the design, configuration, or method of operation of the plant. By implementing corrective actions for any degradation discovered during the required inspections of the containment, the possibility of a new or different kind of accident will not be created. Implementation of the requirements of Subsection IWL of the ASME code and those of 10 CFR 50.55a(b)(2) provide an equally acceptable containment inspection program.
to 2CAN120401 Page 6 of 6 Therefore, this change does not create the possibility of a new or different kind of accident from any previously evaluated.
Criterion 3 - Does Not Involve a Significant Reduction in the Margin of Safety.
The proposed change to incorporate the applicable requirements of Subsection IWL of the ASME Code and of 10 CFR 50.55a(b)(2) into the ANO-2 containment inspection program has no impact on any safety analysis assumptions. The addition of structural integrity requirements to ANO-2 TS Specification 3.6.1.5 imposes consistent requirements with those previously specified in the ANO-2 TSs. The requirements of ASME IWL are more restrictive than those currently provided in the existing ANO-2 technical specifications. As a result, the margin of safety is not reduced by the proposed change.
Therefore, this change does not involve a significant reduction in the margin of safety.
Based upon the reasoning presented above and the previous discussion of the amendment request, Entergy Operations has determined that the requested change does not involve a significant hazards consideration.
5.3 Environmental Considerations The proposed amendment is confined to (i) changes to surety, insurance, and/or indemnity requirements, or (ii) changes to record keeping, reporting, or administrative procedures or requirements. Accordingly, the proposed amendment meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(10). Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed amendment.
6.0 PRECEDENCE The above proposed change for the addition of the reporting requirement is similar to that issued for ANO-1 in Reference 1. The change to meet the current revised standard Technical Specifications is similar to that approved for South Texas Project in the NRC Safety Evaluation dated March 19, 2002 and for the Virgil C. Summer Nuclear Station in Safety Evaluation dated September 6, 2000.

Attachment 3 2CAN1 20401 Proposed Technical Specification Bases Changes (mark-up)
CONTAINMENT SYSTEMS BASES 3/4.6.1.4 INTERNAL PRESSURE AND AIR TEMPERATURE The limitations on containment internal pressure and average air temperature, assuming a worst case relative humidity value of 0 %, ensure that 1) the containment structure is prevented from exceeding its design negative pressure differential with respect to the outside atmosphere of 5.0 psi, 2) the containment peak pressure does not exceed the design pressure of 59 psig during design basis conditions, 3) the ECCS analysis assumptions are maintained, and 4) the containment cooling fan motor qualifications are maintained.
The limitation on containment average air temperature ensures that the containment liner plate temperature does not exceed the design temperature of 300OF during LOCA conditions. The containment temperature limit is consistent with the accident analyses. Figure 3.6-1 represents analysis limits and does not account for instrument error.
3/4.6.1.5 CONTAINMENT STRUCTURAL INTEGRITY This limitation ensures that the structural integrity of the containment will be maintained comparable to the original design standards for the life of the facility. Structural integrity is required to ensure that the containment will withstand the maximum design pressure of 59 psig.
