Subject: Interim 10CFR50.55(e) Report; Service Air System NNS Supports

Dear Sir:

On July 14, 1983, we reported a potential 10CFR50.55(e) item to Region I[Ref erence (b)] regarding supports for the Service Air System which carry aNon-Nuclear Safety (NNS) designation in spite of this systems proximity.tosafety-related equipment. The following information is being filed pursuantto the interim reporting provision of 10CFR50.55(e)(3).

A. Description of Deficiency

We have identified pipe supports on the Service Air Systemclassified as Non-Nuclear Safety (NNS) which are located inproximity to safety-related equipment. The proper classification is

'Non-Nuclear Seismic (NNS-1), whereby tha structural integrity of asupport during a seismic / operating event is assured. We have alsoidentified pipe suppcrts associated stA,W other systems that havebeen classified as NNS and are in proxinfity to safety-related

equipment. This classification discrepancy on the supports thatwere designated as NNS rather than NNS-lyis due to the fact that(

''-this designation was instituted after thepe support designs-wergissued for construction. In addition, a portion of these supporty,plus approximately 700 supports properly classified as NE -1, do not *

have retrievable formal calculations. e'

,

On December 2,1983 [ Reference (f)], wa., accorded this item a' ,jreportable status due to the extensive duration o1 evaluation that ,

would be required to absolutely determine whether this item meetsthe reportability criteria of 10CFR50.55(e).

Our evaluation of the support designs in question is rearlycomplete. A total of 1,362 pipe support points require anevaluation. Of this total, all but thirty-one a'!pport' points remainto be evaluated. \' ..

s

The changes resulting from the evaluaticn of N,331 support points to'date are as follows: . .s,

1. Two-hundred-twelve (212) pipe supports required areclassification f rom NNS to NNS-1.

'

,

K*

,

''2. Sixty (60) pipe supports (some installed) required t

modifications to meet NNS-1 design criteria. g

B. Analysis of Safety Implications

The failure of these pipe supports during a seismic / operating eventcould have adversely impacted the function of safety-relatedequipment.

C. Corrective Action

All pipe supports that do not meet the NNS-1 pipe support criteria,

will be modified to bring the support up to NNS-1 designrequirements.
