Gentlemen:

The purpose of this correspondence is to inform you of a j potentially reportable defect under 10CFR, part 21. We have

! supplied our part no. 77379, flexible hose assembly, to the Calloway plants and have subsequently discovered that the assembly was welded with a 600 rather than a 30 elbow in-stalled. This condition has been reported to the Bechtel Power Corporation in Gaithersburg, Maryland. A copy of the report is enclosed for your reference.

Yours Truly,

15740 Shady Grove Road Gaithersburg, Maryland 20760 Attn: Project Engineering Manager Job 10466-M-133 Calloway Plants, Units 1 and 2 Ref: Bechtel P.O. 10466-M-133-2, Item 1.17 MBC Job No. A14573 MBC P/N 77379 (Hose Assembly), S/N 080 Gentlemen:

The purpose of this letter is to bring to your attention a defect we believe exists in the above described hose assembly which was shipped to the Calloway plant on April 7, 1981.

We have received from the Wolf Creek plant another P/N 77379 l hose assembly in which a 60 rather than a 30 elbow (P/N l 77968) had been installed. Since the two hose assemblies l (The one built for Wolf Creek and the one built for Calloway) l were manuf ac tured at the same time and from the same materials, l we believe that the assembly shipped to you also has a dis-crepant elbow.

Our Project Engineer, Mr. Ron Nystrom, has determined that, if present, a 600 elbow might result in premature failure of the hose assembly. However, the exact conditions of install-ation of the hose assembly also affect its serviceability.

l Accordingly, we request that you have one of your engineers l contact Mr. Nystrom so that they might determine if the elbow is discrepant and, if so, coordinate in arriving at a dis-position.

l l

METAL +f.;;;f CORPOR ATION We sincerely regret any inednvenience this matter might cause you. Should it prove necessary to rework the hose assembly to conform to our drawing, we shall expedite our work to the best of our ability. Of course, all costs con-nected with reworking the hose assembly would be borne by Metal Bellows Corporacion.

Respectfully,

- O Paul B. Campbell Corp. Vice President, Engineering I
