SUBJECT:

ARKANSAS NUCLEAR ONE, UNIT 1 - WITHDRAWAL OF REQUEST FOR ALTERNATIVE CEP-ISI-007

Dear Sir or Madam:

By letter dated June 21, 2010 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML101720478), Entergy Operations Inc. (Entergy, the licensee), stated that Arkansas Nuclear One, Unit 1 (ANO-1) is withdrawing its Request for Alternative CEP-ISI-007, submitted in 2002 and subsequently authorized by the U.S. Nuclear Regulatory Commission (NRC) staff. This fulfills a commitment made by Entergy in its letter dated June 11, 2009 (ADAMS Accession No. ML091620414).

In a letter dated December 6, 2002 (ADAMS Accession No. ML030150438), Entergy submitted Request for Alternative CEP-ISI-007 to use the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (Code), Code Case N-663, "Alternative Requirements for Classes 1 and 2 Surface Examinations,Section XI, Division 1." Entergy proposed to use ASME Code Case N-663 in its entirety as an alternative to the surface examination requirements of ASME Code,Section XI, Table IWB-2500-1 for examination categories B-F (Nominal Pipe Size (NPS) 4 and larger) and B-J (NPS-4 and larger) and Table IWC-2500-1 for examination categories C-F-1 and C-F-2. By letter dated August 26, 2003 (ADAMS Accession No. ML032390190), the U.S. Nuclear Regulatory Commission (NRC) authorized the relief request, pursuant to 50.55a(a)(3)(i) of Title 10 of the Code of Federal Regulations (10 CFR), for the third 10-year lSI inservice inspection interval for ANO-1.

By letter dated June 11, 2009, Entergy requested authorization to implement a risk-informed inservice inspection (RI-ISI) program based on the ASME Code Case N-716, "Alternative Piping Classification and Examination Requirements,Section XI, Division 1," as documented in the Request for Alternative AN01-ISI-014. This relief request was authorized by the NRC staff by letter dated June 2, 2010 (ADAMS Accession No. ML101170127). In its submittal for Request for Alternative AN01-ISI-014, Entergy made a regulatory commitment which stated that, Request for Alternative CEP-ISI-007 pertaining to the application of Code Case N-663 will be withdrawn for use at ANO-1 upon NRC approval of the RIS_B [risk informed/safety-based inservice inspection] Program submittal.

Based on the above, the NRC staff acknowledges the letter dated June 21, 2010, as the licensee's withdrawal of Request for Alternative CEP-ISI-007 and fulfillment of the regulatory

-2 commitment made in its letter dated June 11, 2009. If you have any questions, please contact me at (301) 415-1480 or e-mail at kaly.kalyanam@nrc.gov.
