Gentlemen:
In letter 2CAN088915, dated August 31, 1989 Entergy Operations submitted relief requests for Arkansas Nuclear One, Unit 2 (ANO-2) for the first 10-year interval.                  These requests were for relief ftom certain ASME Section XI Inservice Inspection (ISI) requirements because only limited
(                examinations could be performed.                  The NRC subsequently requerted l                additional information concerning these relief requests in letter dated Septa.mber 10, 1991 (2CNA099102).                 In {{letter dated|date=February 13, 1992|text=letter dated February 13, 1992}} (2 car 029202), Entergy Operations stated that ANO-2 was unable to provide the soecific infarmation requested but committed to submit a best estimate of the percentage of the Code-required coverage. The purpore of this submittal is to provide these best estimates for the coverage.
l The Code required coverage was estimated and placed into four categories.
These categories are 0 to 25%; 26 to 50%; $1 to 75%; and 76 to 100% of the Code required coverage of the weld. Attached is a listing of those welds that fell within the first, second, third, and fourth category.
respectively.
l l
The attachment also provides additional information, including items such as a description of the examination area, examination volume and/or area, the category of the weld, and the method used to perform the examination.
Based on further review, there are several welds in which the Code required coverage was considered to be met. These welds are those identified by 100% in the attached list.                  It is Entergy Operations' conclusion that NRC relief is no longer necessary and the relief for those welds is herewith withdrawn.
