GNRO-2016/00062 and their integral attachments and metallic shell and penetration liners of Class CC pressure retaining components and their integral attachments are subject to the requirements of Subsection IWE.

In accordance with IWA-1320 and IWL-11 00, Class CC reinforced concrete and post-tensioning systems of concrete containments are subject to the requirements of Subsection IWL.

ASME Section XI Code of Record In accordance with 10CFR50.55a(g), Entergy is required to update the ASME Section XI (the Code) ContainmenfiSI Program once every ten years. The updated Containment lSI Program is required to comply with the latest edition and addenda of the Code incorporated by reference in 10CFR50.55a one year prior to the start of the interval per 10CFR50.55a(g)(4)(ii). The prior interval dates for GGNS were June 2, 1997 through May 31, 2008 [2nd Interval].

Based on "lock in" date of May 31,2007, the 2001 Edition with the 2003 Addenda of ASME Section XI is the version of Section XI that Entergy must meet for the current interval [3rd Interval].

ASME Section XI Code Cases Per 10CFR50.55a(g), ASME Code Cases that have been determined to be suitable for use in lSI Program Plans by the NRC are listed in RG 1.147 "Inservice Inspection Code Case Acceptability-ASME Section XI, Division 1". The use ofCode Cases (other than those listed in Regulatory Guide 1.147) may be authorized by the Director of the Office of Nuclear Reactor Regulation upon request pursuant to 10CFR50.55a(a)(3). The ASME Section XI Code Cases incorporated into the Containment lSI Program Plan are listed in Table 3.3.8-1. At the time this Containment lSI Program Plan was originally issued, Revision 15 of Regulatory Guide 1.147 was the latest revision. At the time this Containment lSI Program Plan was issued, Revision 16 of Regulatory Guide 1.147 was the latest revision.

GNRO-2016/00062 Per IWA-2430(d), for components inspected under Program B, each of the inspection intervals may be extended or decreased by as much as one year. Adjustments shall not cause successive intervals to be altered by more than one year from the original pattern of intervals.

Per IWA-2430(e), in addition to the interval adjustment allowed per IWA-2430(d), for power units that are out of service continuously for 6 months or more, the inspection interval during which the outage occurred may be extended for a period equivalent to the outage and the original pattern of intervals extended accordingly for successive intervals.

Inspection Schedule-Subsection IWE Per IWA-2420, inspection plans shall be prepared for the first inservice interval and subsequent inspection intervals. Per IWA-2420(b), an implementation schedule for performance of examinations and tests shall be prepared for each inspection plan.

Subarticle IWE-2400 includes the requirements for the scheduling of examination and tests for Class MC components and Metallic Liners of Class CC components.

Specific scheduling criteria are included in IWE-2412 for plants, which are employing Inspection Program B. This paragraph references Table IWE-2412-1, which includes minimum and maximum percentages of examinations required to be completed by each inspection period. Table 3.3.8-2 summarizes this information. Figure 3.3.8-1 provides interval, period and approximate outage dates.

Per IWE-2412(a), the following examinations listed in Table IWE-2500-1 as deferrable to the end of the inspection interval are not required to meet the criteria in Table IWE-2412-1:

a) Category E-A, Item No E1.12 - Wetted Surface of Submerged Areas b) Category E-A, Item No E1.20- BWR Vent System Accessible Surface Areas TABLE 3.3.8-2 IWE COMPONENT SCHEDULING INSPECTION INSPECTION PERIOD MINIMUM MAXIMUM INTERVAL (CALENDAR YEARS EXAMINATIONS EXAMINATIONS OF SERVICE WITHIN COMPLETED, % CREDITED, %

THE INTERVAL) 3 ra 3 . 16 50 ra 1 3 7 50 75 ra 3 10 100 100 1 If the first period completion percentage for any examination category exceeds 34%, at least 16% of the required examinations shall be performed in the second period.

GNRO-2016/00062 Inspection Periods-Subsection IWL Subarticle IWL-2400 includes the requirements for the scheduling of examination and tests for Class CC Concrete components. Table 3.3.8-3 summarizes the Subsection IWL Examination periods for GGNS.

Concrete examinations shall be conducted every 5 years (a period) as described in IWL-2410(a) and (c). For the purposes of this program section, an IWL inspection period shall be defined as the window of time allowed by IWL-2410 for the completion of one set of IWL examinations.

Concrete surface areas affected by repair/replacement activities shall be examined in accordance with IWL-2410(d).

Table 3.3.8-3 Projected IWL Examination Periods Period Start Date End Date 30 Year 1/2/2011 1/2/2013 35 Year 1/2/2016 1/2/2018 40 Year 1/2/2021 1/2/2023 45 Year 1/2/2026 1/2/2028 50 Year 1/2/2031 1/2/2033 55 Year 1/2/2036 1/2/2038 60 Year 1/2/2041 1/2/2043 Subsection IWE Component Selection Criteria Class MC components are selected for examination per the requirements of the 2001 Edition with the 2003 Addenda of Section XI, Table IWE-2412-1. IWE-2420(a) states that the sequence of component and component support examinations established during the first interval shall be repeated during the successive intervals to the extent practical. Entergy will select and examine a majority of the Class MC components and component supports in accordance with this criteria. However, Entergy has adopted Code Case N-624 as approved in Regulatory Guide 1.147, which states that the sequence of examinations may be modified provided the percentage of requirements of Table IWE-2412-1 are met. Code Case N-624 allows the sequence of examinations established during the first interval to be modified by factors such as scaffolding erection, radiological concerns, insulation removal or other considerations.

The Containment Inspection Engineer selects examinations for a given interval and for a given period in accordance with the requirements of 10CFR50.55a and ASME Section XI.

Examination selections are documented in the IDDEAL database. The implementing organization determines the appropriate schedule for completion of the examinations within a given period.

Examination Category E-A Selection

GNRO-2016/00062 remain essentially unchanged, they no longer require Examination Category E-C examination.

10CFR50.55a Limitations and Modifications

• The requirements of Table IWE-2500-1 Examination Category E-C, are modified by 10CFR50.55a as follows:

• Per 10CFR50.55a(b)(2)(ix)(G), the VT-1 examination method must be used to conduct the examination in Item E4.11 of Table IWE-2500-1.

The "owner-defined" visual examination provisions in IWE- 231O(a) are not approved for use for VT-1 examinations.

• Per 10CFR50.55a(b)(2)(ix)(I), the ultrasonic examination acceptance standard specified in IWE-3511.3 for Class MC pressure-retaining components must be applied to metallic liners of Class CC pressure-retaining components.

Identification of IWE Augmented Examination of Containment Surface Areas Examination Category E-C Whenever a plant has an area(s) requiring examination under Category E-C, the area shall be identified in the IDDEAL database. Areas requiring Category E-C examination are listed in Table 3.3.8-4 Table 3.3.8-4 Areas Requiring Category E-C Examination Component Description Exam Requirements 10 EC-01 Corroded liner plate area under Ultrasonic Containment Penetration 38.
