SUBJECT:

REQUEST TO USE CODE CASE N-509 AS AN ALTERNATIVE TO ASME CODE SECTION XI FOR CRYSTAL RIVER NUCLEAR PLANT, UNIT 3 (TAC NO. M98261) 1

Dear Mr. Anderson:

1 1

Regulatory Guide, 1.147, Inservice Inspection Code Case Acceptability ASME '

Section XI, Division 1, Revision 11, dated October 1994, lists those Section XI ASME Code Cases that are generally acceptable to the NRC staff for implementation in the inservice inspection of light-water-cooled nuclear power I plants. Code Case N-509, " Alternative Rules for the Selection and Examination of Intergrally Welded Attachments,Section XI, Division 1," is not included in the NRC Regulatory Guide 1.147.

By letter dated March 24, 1997, you submitted Relief Request (RR) 97-001-II.

Pursuant to 10 CFR 50.55a(a)(3)(i), you requested approval for implementing Code Case N-509 for certain surface and volumetric examination of integral attachment welds in Classes 1, 2 and 3 piping.

We have evaluated your relief request and determined that use of Code Case N-509 would provide an acceptable level of quality and safety and, therefore, is authorized pursuant to 10 CFR 50.55a(a)(3)(1) and is acceptable. Please be advised that use of Code Case N-509 is acceptable until such time as it may be included in a future revision of Regulatory Guide 1.147. At that time, you should follow any provisions and limitations that may be described in the Regulatory Guide 1.147 concerning the use of Code Case N-509.

Our evaluation and conclusions are contained in the attached safety evaluation. This completes our effort under Technical Assignment Control (TAC) No. M98261 and the TAC is closed.

Sincerely, Original signed by Frederick J. Hebdon, Director rg, i QQ* h h h Project Directorate II-3 Division of Reactor Projects - I/II l Office of Nuclear Reactor Regulation  !
