The Nuclear Steam Supply System (NSSS) was furnished by Combustion Engineering. The Architect Engineer for ANO 2 during construction was Bechtel Corporation.          Nuclear Regulatory Commission (NRC)
Regulatory Guide 1.26 and 10 CFR 50.2 were used to determine the ASME Code classification for Class 1, 2 and 3 Systems, Structures, and Components.
1.3 Inspection Intervals The Operating License for ANO 2, Docket No. 50-368 was issued on September 1, 1978.
The commercial operation date for ANO 2 was March 26, 1980. The First Ten-Year inspection interval ended March 31, 1990. The Second Ten-Year Inspection Interval concluded on March 26, 2000. The Third Inspection Interval for ANO 2 was completed March 25, 2010. The Fourth Inspection Interval is divided into inspection periods consistent with Table IWB-2412-1. The inspection periods are scheduled as follows:
1st Period: From March 26, 2010 to March 25, 2013            (3 Years) 2nd Period: From March 26, 2013 to March 25, 2017            (4 Years) 3rd Period: From March 26, 2017 to March 25, 2020            (3 Years)
In accordance with ASME Section XI, IWB-2412(b) and IWA-2430, that portion of an inspection interval described as an inspection period may be decreased or extended by as much as 1 year to enable inspections to coincide with a plant refueling outage.
However, the adjustments must not cause successive intervals to be altered by more than 1 year. Outages during the fourth inservice inspection interval are scheduled as follows:

However, when communicating with the NRC and in written requests to deviate, the terms as defined below must be used for clarity and to satisfy 10 CFR 50.55a. Submittals to the NRC must clearly identify which of the below rules are being used to request the deviation.
Table 3.0-1 contains an index of Relief Requests written in accordance with 10 CFR 50.55a(a)(3) and (g)(5). The applicable Entergy submittal and NRC Safety Evaluation Report (SER) correspondence numbers are also included for each request.
Only requests associated with the ISI program and the supporting nondestructive examination requirements are listed in Table 3.0-1. Requests applicable to System Pressure Testing and Repair/Replacement Activities are identified in their respective program documents.
3.1 Request for Alternatives When seeking an alternative to the rules contained in 10 CFR 50.55a(c), (d), (e), (f), (g),
or (h) the request is submitted under the provision of 10 CFR 50.55a(3). Once approved by the Director, Office of Nuclear Reactor Regulation, the alternative may be incorporated into the ISI program. These types of requests are typically used to request use of Code Cases, Code Edition, or Addenda not yet approved by the NRC. Request for Alternatives must be approved by the NRC prior to their implementation or use. Within the provisions of 10 CFR 50.55a(3) there are two specific methods of submittal:

Program Section No.: SEP-ISI-105 Revision No.:                0 Page No.:                    Page 22 of 82 3.1.1 10 CFR 50.55a(a)(3)(i) allows alternatives when authorized by the NRC, if the proposed alternatives would provide an acceptable level of quality and safety.
Requests submitted under these provisions are not required to demonstrate hardship or burden.
3.1.2 10 CFR 50.55a(a)(3)(ii) also allows alternatives when authorized by the NRC, if compliance with the specified requirements would result in hardship or unusual difficulty without a compensating increase in the level of quality and safety. When submitted under this provision, there must be evidence of unusual hardship or difficulty. Typically this hardship will be dose or excessive disassembly.
3.2  Relief Request Required due to Impracticality or Limited Examinations 10 CFR 50.55(a)(g)(5)(iii) and (iv) allows relief to be requested in instances when a Code requirement is deemed impractical with (iv) being specific to examination requirements that are determined to be impractical. The provisions of these two paragraphs are typically used to address impracticalities like limited examination coverage. Under 10 CFR 50.55(a)(g)(5)(iv), relief requests for examination impracticalities must be provided to the NRC no later than 12 months after the end of the active 120-month interval In cases where the ASME Section XI requirements for inservice inspection are considered impractical, Entergy will notify the NRC and submit information to support the determination, as required by 10 CFR 50.55a(g)(5). The submittal of this information will be referred to as a Request for Relief.
In the event that the entire examination volume or surface (as defined in the ASME Code) cannot be examined due to interference by another component or part geometry, then in accordance with Code Case N-460, a reduction in examination volume or area is acceptable if the reduction is less than 10%. In the event that the reduction in examination volume or area is 10% or greater, a request for relief will be submitted. NRC Information Notice 98-42 provides additional guidance that all ASME Section XI examinations should meet the examination coverage criteria established in Code Case N-460. Therefore, the guidance included in NRC Information Notice 98-42 will be followed by Entergy when determining whether to prepare a relief request or apply the criteria of Code Case N-460 for examinations where less than 100% coverage of any Section XI examination is obtained. This does not apply to the bare metal visual examination required by Code Case N-729-1. When performing visual examinations to meet N-729-1, the requirements of N-729-1 shall be used for determining allowance for partial examination of the required surface.
3.3  Requests to use Later Edition and Addenda of ASME Section XI On July 28, 2004, the NRC published Regulatory Issue Summary (RIS) 2004-12, Clarification on Use of Later Editions and Addenda to ASME OM Code and Section XI.

Program Section No.: SEP-ISI-105 Revision No.:                0 Page No.:                    Page 23 of 82 This RIS clarifies the NRC position on using Editions and Addenda of Section XI, in whole or in part, later than those specified in the ISI program. If the desired Edition or Addenda are referenced in 10 CFR 50.55a(b)(2), the request is submitted following the guidance of the RIS. These types of request are not required to demonstrate hardship, difficulty, or provide evidence of quality and safety. They do need to ensure that all related requirements are also used. Requests to use edition and/or addenda of ASME Section XI that are referenced in 10 CFR 50.55a(b)(2) that are later than the initial Code of Record established for the ISI program shall be submitted under the provisions of 10 CFR 50.55a(g)(4)(iv).

These examinations may result from activities including, but not limited to, commitments made to the NRC outside the scope of 10 CFR 50.55a, internal commitments, License Renewal commitments, or industry initiatives. These examinations may use ASME Section XI techniques and procedures as defined in the commitment, however, the requirements of ASME Section XI, including reporting, do not apply. These examinations are not required by the ASME Code and are not included in the summary totals for the specific examination category. Changes to these examination requirements and schedules are outside of 10 CFR 50.55a and are required to be evaluated using the 10 CFR 50.59 screening/review process.
5.1 Augmented Examination Programs Augmented Examination Programs are those that have been developed to address NRC or industry concerns in which ANO has committed to perform. The augmented examinations addressed by the ANO 2 ISI Program during the fourth inspection interval are as follows:

Regulatory Basis: The regulatory basis for this augmented examination program is NRC Regulatory Guide 1.14, Revision 1.

====5.1.2 MRP-139====
Primary System Piping Butt Weld Inspection and Evaluation Guideline Source Document: Materials Reliability Project MRP-139 Associated Document: NEI 03-08 letter

==Purpose:==
Components in the primary coolant system containing Alloy 600 material and 82/182 dissimilar metal butt welds may be susceptible to degradation cause by primary water stress corrosion cracking (PWSCC). MRP-139 is the industry standard for examination of primary system components which may be susceptible to PWSCC corrosion.
Scope: The scope includes those primary coolant system components containing Alloy 600 material and 82/182 dissimilar metal butt welds.
Method: Surface and volumetric examination methods are required and are based on the component material, its operating temperature, stress reduction methods utilized, (if applicable) and the component repair history and are assigned by Tables 6.1 and 6.2 of MRP-139.
Industry Code or Standards: Materials Reliability Project MRP-139.
Frequency: Examination frequencies are based on the component material, its operating temperature, stress reduction methods utilized, (if applicable) and the component repair history and are assigned by Tables 6.1 and 6.2 of MRP-139.
Acceptance Criteria or Standard: ASME Section XI, IWB-3500.
Regulatory Basis: Nuclear Energy Institute (NEI) 03-08 Initiative.
Note: The visual examinations recommended by MRP-139 are replaced with the visual examinations contained in Code Case N-722 required by 10 CFR 50.55a.

====5.1.3 MRP-192====
RHR Mixing Tee Thermal Fatigue Source Document: Materials Reliability Project MRP-192

Program Section No.: SEP-ISI-105 Revision No.:                 0 Page No.:                     Page 28 of 82 Associated Document: NEI 03-08 letter

==Purpose:==
In 1998, a leak occurred in the Civaux 1 reactor residual heat removal system (RHRS). The leak was from the extrados of an elbow immediately downstream of where the bypass line and the main flow line of one of the parallel RHR heat exchangers joined together due to thermal fatigue. There were many other part-wall cracks in other regions of the piping immediately downstream of the mixing tee.
An assessment performed on a group of US Plants indicated that all U.S. PWR reactor residual heat removal systems are designed to allow bypass around the system heat exchanger to control the temperature of the flow back to the reactor.
Thus, mixing of hot and cold fluids can occur at the mixing tee downstream of the heat exchanger. This guideline is provided as good practice under the Nuclear Energy Institute (NEI) 03-08 implementation protocol.
Scope: A system evaluation was conducted to determine where mixing conditions will occur or have occurred during plant heatup and cooldown operations. Results of the ANO2 evaluation recommended that welds 55-041, 55-042, and 55-053 need inspection.
Method: Volumetric examination methods are required and require the examiner to complete Computer Based NDE Training for Thermal Fatigue Cracking MRP-36.
Industry Code or Standards: Materials Reliability Project MRP-192.
Frequency: Every 10 Years.
Acceptance Criteria or Standard: ASME Section XI, IWC-3500.
Regulatory Basis: Nuclear Energy Institute (NEI) 03-08 Initiative.

Several of ANO Unit 2 systems or portions of systems are excluded from system and component NDE as allowed by Articles IWB-1200, IWC-1200, and IWD-1200. However, these portions of systems are not excluded from the pressure testing requirements of ASME Code, Section XI, except as allowed by Articles IWA-5000, IWB-5000, IWC-5000, and IWD-5000. System information for the NDE Program is provided in Table 6.1, ANO 2 ASME Code Class Systems. The 2001 Edition through the 2003 Addenda of the ASME Code, Section XI defines the inspection requirements for each of the ASME Code Classes within the fourth inspection interval, which began on March 26, 2010.
6.2 Per IWA-1400(a) of the 2001 Edition through the 2003 Addenda of Section XI, it is the owner's responsibility to determine the appropriate Code Classes for each component and to identify the system boundaries subject to inspection. IWA-1400(a), footnote 1, states that classification criteria are specified in 10 CFR 50. This reference is to footnote 9 of 10 CFR 50.55a which references Regulatory Guide 1.26 and Section 3.2.2 of NUREG-0800.
6.3 The component classifications of the ASME Code (Class 1, 2, or 3) determine the rules and requirements for inspection and define the Section XI examination boundaries.
Because early vintage nuclear plants were designed and constructed before Section III of the ASME Boiler and Pressure Vessel Code was incorporated into 10 CFR 50.55a, the ASME Section XI Code classifications for ISI may differ from the original design classifications. Therefore, while the ASME Code classifications determine the rules for repairs and replacements and the component inspection requirements, repairs and replacements are generally performed to meet the specifications of the original design code.
6.4 The 2008 Code of Federal Regulations provides criteria for the classification of Quality Group A components. In previous issues of 10 CFR, this criterion was provided in section 50.2(v). Regulatory Guide 1.26, Quality Group Classifications and Standards for Water, Steam, and Radioactive Waste Containing Components of Nuclear Power Plants, provides criteria for the classification of Quality Group B, C, and D components.
Regulatory Guide 1.26 was used for ASME Code, Section XI component classification at ANO 2.

(2)   Applicable portions of the shutdown cooling pressure boundary function. That is, Class 1 and 2 welds of systems or portions of systems needed to utilize the normal shutdown cooling flow path either:
(a)    As part of the RCPB from the reactor pressure vessel (RPV) to the second isolation valve (i.e., farthest from the RPV) capable of remote closure or to the containment penetration, whichever encompasses the larger number of welds; or (b)    Other systems or portions of systems from the RPV to the second isolation valve (i.e., farthest from the RPV) capable of remote closure or to

Program Section No.: SEP-ISI-105 Revision No.:                  0 Page No.:                      Page 79 of 82 the containment penetration, whichever encompasses the larger number of welds; (3)   That portion of the Class 2 feedwater system [> 4 inch nominal pipe size (NPS)]
of pressurized water reactors (PWRs) from the steam generator to the outer containment isolation valve; (4)   Piping within the break exclusion region (> NPS 4) for high-energy piping systems as defined by the Owner. This may include Class 3 or Non-Class piping; and (5)   Any piping segment whose contribution to Core Damage Frequency (CDF) is greater than 1E-06 (or 1E-07 for Large early event frequency (LERF)) based upon a plant-specific PSA of pressure boundary failures (e.g., pipe whip, jet impingement, spray, inventory losses). This may include Class 3 or Non-Class piping.
10.1.2 Failure Potential Assessment Failure potential estimates were generated utilizing industry failure history, plant-specific failure history, and other relevant information. These failure estimates were determined using the guidance provided in EPRI TR-112657 (i.e., the EPRI RI-ISI methodology),
with the exception of the deviation discussed below.
As described in section 2.3.3 above, CC N-716 augments the generic HSS welds with a search for plant-specific HSS welds based on the flooding analysis. The flooding analysis identifies areas that may be sensitive to floods (i.e., potential HSS areas) and then evaluates the failure potential of piping segments in areas that are sensitive to flooding. The failure frequencies used in the Entergy flooding studies were not based on Entergy plant specific data as there had not been significant flooding experience at Entergy. As such, failure frequencies were obtained from various industry reports as defined in each plants template submittal.
A deviation to the EPRI RI-ISI methodology has been implemented in the failure potential assessment for each site. Table 3-16 of EPRI TR-112657 contains criteria for assessing the potential for thermal stratification, cycling, and striping (TASCS).
These additional considerations for determining the potential for thermal fatigue as a result of the effects of TASCS provide an allowance for considering cycle severity.
The above criteria have previously been submitted by EPRI to the NRC for generic approval [letters dated February 28, 2001 and March 28, 2001, from P.J. ORegan (EPRI) to Dr. B. Sheron (USNRC), Extension of Risk-Informed Inservice Inspection Methodology]. The methodology used in the Entergy RIS_B applications for assessing TASCS potential conforms to these updated criteria. Final materials reliability program (MRP) guidance on the subject of TASCS will be incorporated into the RIS_B applications, if warranted.
10.1.3 Element and NDE Selection

Program Section No.: SEP-ISI-105 Revision No.:                  0 Page No.:                      Page 80 of 82 Code Case N-716 provides criteria for identifying the number and location of required examinations. Ten percent of the HSS welds shall be selected for examination as follows:
(1)   Examinations shall be prorated equally among systems to the extent practical, and each system shall individually meet the following requirements:
(a)    A minimum of 25% of the population identified as susceptible to each degradation mechanism and degradation mechanism combination shall be selected.
(b)    If the examinations selected above exceed 10% of the total number of HSS welds, the examinations may be reduced by prorating among each degradation mechanism and degradation mechanism combination, to the extent practical, such that at least 10% of the HSS population is inspected.
(c)    If the examinations selected above are not at least 10% of the HSS weld population, additional welds shall be selected so that the total number selected for examination is at least 10%.
(2)   At least 10% of the RCPB welds shall be selected.
(3)   For the RCPB, at least two-thirds of the examinations shall be located between the first isolation valve (i.e., isolation valve closest to the RPV) and the RPV.
(4)   A minimum of 10% of the welds in that portion of the RCPB that lies outside containment (e.g., portions of the main feedwater system in BWRs) shall be selected.
(5)   A minimum of 10% of the welds within the break exclusion region (BER) shall be selected.
In contrast to a number of RI-ISI Program applications where the percentage of Class 1 piping locations selected for examination has fallen substantially below 10%, Code Case N-716 mandates that 10% be chosen. Section 4 of EPRI TR-112657 was used as guidance in determining the examination requirements for these locations.
10.1.4 Risk Impact Assessment The RIS_B Program has been conducted in accordance with Regulatory Guide 1.174 and the requirements of Code Case N-716, and the risk from implementation of this program is expected to remain neutral or decrease when compared to that estimated from current requirements.
This evaluation categorized segments as high safety significant or low safety significant in accordance with Code Case N-716, and then determined what inspection changes are proposed for each system. The changes include changing the number and location of inspections and in many cases improving the effectiveness of the inspection to account for the findings of the RIS_B degradation mechanism assessment. For example, examinations of locations subject to thermal fatigue will be

Program Section No.: SEP-ISI-105 Revision No.:                   0 Page No.:                       Page 81 of 82 conducted on an expanded volume and will be focused to enhance the probability of detection (POD) during the inspection process.
10.1.5 Quantitative Analysis Code Case N-716 has adopted the EPRI TR-112657 process for risk impact analyses whereby limits are imposed to ensure that the change in risk of implementing the RIS_B Program meets the requirements of Regulatory Guides 1.174 and 1.178. The EPRI criterion requires that the cumulative change in CDF and LERF be less than 1E-07 and 1E-08 per year per system, respectively.
Entergy has conducted a risk impact analysis per the requirements of Section 5 of Code Case N-716 that is consistent with the Simplified Risk Quantification Method described in Section 3.7 of EPRI TR-112657. The analysis estimates the net change in risk due to the positive and negative influences of adding and removing locations from the inspection program.
The conditional core damage probability (CCDP) and conditional large early release probability (CLERP) values used to assess risk impact were estimated based on pipe break location. Based on these estimated values, a corresponding consequence rank was assigned per the requirements of EPRI TR-112657 and upper bound threshold values were used as provided below. Consistent with the EPRI risk-informed methodology, the upper bound for all break locations that fall within the high consequence rank range was based on the highest CCDP value obtained (i.e., Large LOCA for W3).
The likelihood of pressure boundary failure (PBF) is determined by the presence of different degradation mechanisms and the rank is based on the relative failure probability. The basic likelihood of PBF for a piping location with no degradation mechanism present is given as xo and is expected to have a value less than 1E-08.
Piping locations identified as medium failure potential have a likelihood of 20xo. These PBF likelihoods are consistent with References 9 and 14 of EPRI TR-112657. In addition, the analysis was performed both with and without taking credit for enhanced inspection effectiveness due to an increased POD from application of the RIS_B approach.
Table 3.4-1 of the ANO 2 template submittal presents a summary of the RIS_B Program versus 2001 Edition through the 2003 Addenda of ASME Section XI program requirements on a per system basis. The presence of FAC was adjusted for in the quantitative analysis by excluding its impact on the failure potential rank. The exclusion of the impact of FAC on the failure potential rank and therefore in the determination of the change in risk is performed, because FAC is a damage mechanism managed by a separate, independent plant augmented inspection program. The RIS_B Program credits and relies upon this plant augmented inspection program to manage this damage mechanism. The plant FAC Program will continue to determine where and when examinations shall be performed. Hence, since the

Program Section No.: SEP-ISI-105 Revision No.:                 0 Page No.:                     Page 82 of 82 number of FAC examination locations remains the same before and after and no delta exist, there is no need to include the impact of FAC in the performance of the risk impact analysis.
10.1.6 Implementation and Monitoring Program Upon approval of the RIS_B Program, procedures that comply with the guidelines described in EPRI TR-112657 will be prepared to implement and monitor the program.
The applicable aspects of the ASME Code not affected by this change will be retained, such as inspection methods, acceptance guidelines, pressure testing, corrective measures, documentation requirements, and quality control requirements. Existing ASME Section XI program implementing procedures will be retained and modified to address the RIS_B process, as appropriate.
The monitoring and corrective action program will contain the following elements:
A. Identify B. Characterize C. Evaluate, (1) Determine the cause and extent of the condition identified (2) Develop a corrective action plan or plans D. Decide E. Implement F. Monitor G. Trend The RIS_B Program is a living program requiring feedback of new relevant information to ensure the appropriate identification of HSS piping locations. As a minimum, this review will be conducted on an ASME period basis. In addition, significant changes may require more frequent adjustment as directed by NRC Bulletin or Generic Letter requirements, or by industry and plant-specific feedback.}}
