ASME Code Components Affected All check valves within the Inservice Testing (IST) program.2. Applicable Code Edition and Addenda Currently, River Bend Station (RBS) is committed to ASME/ANSI OM-1 Oa, 1988 Edition.The next 120-month interval starts December 2007.3. Proposed Subsequent Code Edition and Addenda (or Portion)Pursuant to 10 CFR 50.55a(f)(4)(iv), Entergy Operations, Inc. (Entergy) requests permission to use Subsection ISTC of the 2001 Edition with 2003 Addenda of ASME Operation and Maintenance (OM) Code for the conduct of check valve testing at RBS.4. Related Requirements There are no related requirements.

The NRC approved the use of Appendix II condition monitoring program requirements specified in the 2001 Edition and 2003 Addenda with no limitations or modifications as documented in 10 CFR 50.55a(b)(3)(iv).

In Federal Register 69 FR 58814, the NRC stated in part: "The modifications in (b)(3)(iv) does not apply to the 2003 Addenda of the ASME OM Code because the earlier Code provisions on which this regulation was based were revised in the 2003 Addenda of the ASME OM Code to address the underlying issues which led to the NRC to impose the modification.

The check valve monitoring program requirements in Appendix II of the 2003 Addenda of the ASME OM Code are equivalent to the check valve monitoring program requirements in § 50.55a(b)(3)(iv)." Unlike earlier editions and addenda of the OM Code, the 2003 Addenda of the 2001 Edition contains the modifications imposed by the NRC for those earlier editions and addenda. Included in these requirements is bi-directional testing of check valves. By adopting this edition and addenda of the OM Code, Entergy will comply with these requirements.

5. Duration of Proposed Request Entergy will begin implementing the Appendix 11 condition monitoring program upon approval of this request. Entergy has identified 580 Class 1, 2, and 3 check valves that are currently required to be uni-directionally tested in accordance with the IST Plan. Of these, 340 are scheduled to be tested during outages. Entergy will begin incorporating these 340 check valves into the Appendix II condition monitoring program upon approval 1 of 2 of this request. By completion of the spring 2006 refueling outage (RF13), these valves will meet the Appendix II or ISTC requirements for bidirectional testing.The remaining 240 valves that are unii-directionally tested in accordance with the IST Plan are currently tested on-line. By the fall 2007 refueling outage (RF1 4), these valves will meet the Appendix II or ISTC requirements for bidirectional testing.For those Class 1, 2, and 3 check valves currently required to be bi-directionally tested in accordance with the IST Plan, Entergy will continue to bi-directionally test these valves.Entergy will apply the requirements of Subsection ISTC to these valves by December 1, 2007.2 of 2 ENCLOSURE 2 CNIRO-2006-00002 LICENSEE-IDENTIFIED COMMITMENTS Enclosure 2 to CNRO-2006-00002 Page 1 of 1 LICENSEE-IDENTIFIED COMMITMENTS TYPE (Check one) SCHEDULED ONE-TIME CONTINUING COMPLETION COMMITMENT ACTION COMPLIANCE DATE 1.
