. Dear Mr. Hutchinsor -

.By letter dated June 12, 1996, Energy Operations, Inc. (E01) proposed an

alternative examination for ANO-1 steam generators. Specifically, E01 i proposed to examine all of the Code _ category B-D nozzles on one of the steam generators rather than both steam generators.

l The NRC staff evaluated the Request for Relief No.96-001 to use a sampling i

philosophy and perform volumetric examination on the Class 1 nozzles and inner radius (IR) sections of only one steam generator in lieu of the Code l requirement of volumetric examination of all Class 1 steam generator nozzles E and nozzle IR sections. The staff concluded that: 1) r,ursuant to

! 10 CFR.50.55a(a)(3)(1), the proposed alternative does r.ot provide an acceptable level of quality and safety; 2) pursuant to 10 CFR

}

1-50.55a(a)(3)(ii), the licensee has not provided a basis for undue hardship, based on the limited number and safety significance of the nozzles; and 3)

pursuant to 10 CFR 50.55a(g)(6)(1), the licensee has.not provided basis for impracticality. Therefore, the licensee's Request for Relief No.96-001 is denied. Enclosure contains the staff's evaluation and conclusions.

Attachment 1 is the Idaho National Engineering Laboratory Technical Letter Reort.

Dear Mr. Hutchinson:

J By letter dated June 12, 1996, Energy Operations, Inc. (E01) proposed an alternative examination for ANO-1 steam generators. Specifically, E01 proposed to examine. all of the Code category B-D nozzles on one of the steam generators rather than both steam generators.

The NRC staff evaluated the Request for Relief No.96-001 to use a sampling philosophy and perform volumetric examination on the Class 1 nozzles and inner radius (IR) sections of only one steam generator in lieu of the Code  ;

requirement of volumetric examination of all Class 1 steam generator nozzles I and nozzle IR sections. The staff concluded that: 1) pursuant to 10 CFR 50.55a(a)(3)(i),.the proposed alternative does not provide an acceptable level of quality and safety; 2) pursuant to '10 CFR .

50.55a(a)(3)(ii), the licensee has not provided a basis for undue hardship, based on the limited number and safety significance of the nozzles; and 3) pursuant to 10 CFR 50.55a(g)(6)(1), the licensee has not provided basis for 4 impracticality. Therefore, the licensee's Request for Relief No.96-001 is denied. Enclosure contains the-staff's evaluation and conclusions.
