Subject:

Arkansas Nuclear One - Unit 2 Docket No. 50-368 License No. NPF-6 Relief Requests for ANO-2 First 10-Year Inservice Inspection Gentlemen:

During the ANO-2 '2R7 refueling outage scheduled to begin on September 25,

'1989, Arkansas Power and Light Company will be conducting 10-Year Inservice

. Inspection (ISI) activities by performing non-destructive examinations of certain systems /couponents, based on the ASME Section XI 1974 Code through Summer 1975 Addenda.. In the recent preparation of ISI procedures for implementing these activities, our engineering staff has discovered that certain examinations cannot be performed in accordance with code.

requirements due to design / configuration limitations. Because of these limitations, we request relief from certain impractical code requirements in accordance with 10CFR50.55a(g)(5)(iii). Each of the relief requests is detailed in Attachment 1, and system piping and instrument diagrams are enclosed for reference.

One additional relief request is still being prepared and will be submitted prior to the ANO-2 refueling outage. This request will address the low pressure safety injection system hydrostatic test.
