RIVER BEND STATION - UNIT 1 REQUEST No. RBS-ISI-020 IN ACCORDANCE WITH 10 CFR SO.SSa(g)(4)(iv) FOR INSERVICE INSPECTION ITEMS Pursuant to 10 CFR SO.SSa(g)(4)(iv) and in accordance with the guidance of Regulatory Issue Summary (RIS) 2004-12, "Clarification on Use of Later Editions and Addenda to the ASME OM Code and Section XI," Reference 1, River Bend Station, Unit 1, (RBS) requests NRC approval to utilize the 2007 Edition through the 2008 Addenda of the American Society of Mechanical Engineers (ASME) Code,Section XI, Reference 2, for Examination Category C-G Items as defined below.

Description:==
Unit / Inspection Interval Applicability:
2 ASME Section XI, 2001 Edition through the 2003 Addenda, Table IWC-2S00 "Code of Record", Reference 3 C-G CS.10 Pump Casing Welds River Bend Station, Unit 1 / Third 10-Year Inservice Inspection (lSI)
Interval May 31,2008 - November 30,2017
2. Applicable Code Edition and Addenda
The Code of Record for the current Third 10-Year lSI Interval at RBS is ASME Section XI, 2001 Edition through the 2003 Addenda. This Code of Record is applicable to the Examination Category C-G welds, for which the use of a subsequent ASME Code Edition and Addenda is being requested.
- 3. Proposed Subsequent Code Edition and Addenda (or Portion)
A. Background In accordance with the 1 O-year update requirements of 10 CFR SO.SSa(g)(4)(ii), ASME Section XI lSI activities at RBS were initially updated for the Third 10-Year lSI Interval to the 2001 Edition through the 2003 Addenda, with an implementation date of May 31,2008.
B. Proposed Use of Subsequent Code Edition and Addenda The subsequent Code edition and addenda proposed for the RBS lSI Program, Examination Category C-G, is ASME Section XI, 2007 Edition through the 2008 Addenda.
In the 2008 Addenda, Examination Category C-G was deleted from the Code.
In the 2001 Edition through the 2003 Addenda of ASME Section XI:
Category C-G requires a surface examination of the pump casing welds in all components in each piping run examined under Examination Category C-F.
ASME Examination Category C-G welds were removed in the ASME Section XI, 2007 Edition through the 2008 Addenda because experience has not identified any failures in pump casing or valve body welds. The requirements for performing these examinations of the pump casing welds resulted in unnecessary radiation exposure for Nondestructive Examination personnel.
For Class 2 welds in pump casings, any degradation of the pump interior will be detected by the mechanic working on the component internals. Through-wall leakage will be detected by the Visual VT-2 examinations during the system pressure tests.
The subsequent Code edition and addenda proposed under this request is the ASME Section XI, 2007 Edition through the 2008 Addenda, for Examination Category C-G. The 2008 Addenda of Section XI has been incorporated into the regulations by reference in (a)(1 )(ii), as published in the Federal Register on June 21,2011 (76 FR 36232), and became effective July 21, 2011. Furthermore, 10 CFR SO.SSa(b) contains no conditions or provisions that pertain to Examination Category C-G items in the 2007 Edition through the 2008 Addenda of ASME Section XI.
- 4. Related Requirements For the portion of the subsequent Code edition and addenda to be used, no related requirements would need to be implemented since the 2008 Addenda deletes Examination Category C-G from the Code.
- 5. Duration of Proposed Request The duration of this request will be for the RBS Third 10-Year lSI Interval scheduled to be completed by November 30,2017.
