SUBJECT:

MILLSTONE POWER STATION, UNIT NO.3 - WITHDRAWAL OF RELIEF REQUEST IR-3-12 REGARDING THE USE OF AMERICAN SOCIETY OF MECHANICAL ENGINEERING CODE CASE N-513-2 (TAC NO. ME3932)

Dear Mr. Heacock:

By letter dated May 28, 2009 (Agencywide Document Access and Management System (ADAMS) Accession No. ML101380042), Dominion Nuclear Connecticut, Inc. (DNC or the licensee) submitted relief request IR-3-12 for Millstone Power Station, Unit NO.3 (IVIPS3). The proposed relief request would allow DNC to use American Society of Mechanical Engineers (ASME) Code Case N-513-2 during the third 1O-year inservice inspection interval at MPS3. The 2004 Edition of ASME Section XI is the Code of Record for the third 1O-year inservice inspection interval at MPS3.

Code Case N-513-2 was approved for use by the NRC in Regulatory Guide (RG) 1.147, Revision 15, "Inservice Inspection Code Case Acceptability, ASME Section XI, Division 1;"

however, Code Case N-513-2 is only applicable for the ASIVIE Code 1983 Edition with the Winter 1985 Addenda through the 2001 Edition with the 2003 Addenda. Code Case N-513-2 allows for the temporary acceptance of flaws in moderate energy Class 2 or 3 piping. The NRC issued RG 1.147, Revision 16, in October 2010, approving the use of ASME Code Case N-513-3. Code Case N-513-3 supersedes Code Case N-513-2 and is applicable for the ASME Code 1983 Edition with the Winter 1985 Addenda, through the 2007 Edition with the 2008 Addenda. Subsequently, by letter dated November 18,2010 (ADAMS Accession No. ML103230004), DNC withdrew relief request IR-3-12 because it is no longer needed.

The purpose of this letter is to advise that the above-cited request is being treated as withdrawn and TAC No. ME3932 will be closed.

If you have any questions, please contact me at 301-415-1603.
