HARTSVILLE NUCLEAR PLANT A - REPORTABLE DEFICIENCY - QA DOCUMENTATION FOR DRYWELL FRAMED EMBEDMENTS - HTRD-50-518/81-13,

-520/81-11 The subject deficiency was initially reported to NRC-0IE, Region II, Inspector P. A. Taylor and F. Cantreit on May 20 and May 29, 1981, respectively, as NCR's PNPA-142 through 150, 2-HTN, 5-HTN, 6-HTN, and 9- through 12-HTN. In compliance with paragraph 50.55(e) of 10 CFR Part 50, we are enclosing the second interim report on the subject deficiency. We consider 10 CFR Part 21 applicable to this nonconformance. TVA anticipates transmitting the next report on or before November 4, 1981. If you have any questions, please call Jim Domer at FTS 857-2014.

Very truly yours, TENNESSEE VALLEY AUTHORITY l .

• ENCLOSURE HARTSVILE NUCLEAR PLANT A UNIT 1 DRYWELL-FRAMED EMBEDMENTS - QA DOCUMENTATION HTRD-50-518/81-13, -520/81-13 10 CFR 50.55(e)

REPOT.T NO. 2 (INTERIM)

Description g Deficiency The contract with the manufacturer, Atlas Machine and Iron Works, for thu drywoll-framed embedments was canc'elled on February 13, 1981, for lack of performance. TVA was awaiting QA documentation at that time and has subsequently received documentation packages for eleven of the Hartsville Nuclear Plant A unit 1 (HTA-1) framed embedments. Of the 11 embedments, four are e= bedded in the drywell wall, three are installad in wall reinforcing steel, and four (frames 1 through 4) are under contract with Chicago Bridge and Iron for repairs and completion of fabrication. Inspection and examinations of frames 1 through 4 and frames for subsequent units by TVA and its engineering consultants have led TVA to conclude that the adequacy, accuracy, and validity of the QA documentation packages prepared and furnished by Atlas are questionable and it is thus concluded that an investigation to verify the acceptability of the frames installed and embedded at Hartsville Nuclear Plant A unit 1 and those for subsequent units is. necessary.

These conclusions are drawn for the following reasons:

1. Nondestructive testing (magnetic particle) results obtained by TVA on HTA-1 on framos 1 through 4 do not agree with the nondestructive testing reports found in the corresponding documentation packages prepared by Atlas.

2. The results of sectioning and macroetching of samplos taken from representative frames at CBI's Cordova facility indicate unacceptable defects in the welds which should have been detected by Atlas' nondestructive testing.

TVA in its upcoming litigation will attempt to show that Atlas falnified condestructive testing records contained in specific QA documentation packages submitted to TVA.

Interim Progress TVA is presently evaluating all svailable documentation prepared independently of Atlas' documentation packages for the seven frames at Hartsville. *he results of this evaluation will dictate further actions and may require that additional nonconformance reports be written on these frames. Concurrent with this evaluation, the following steps have been or will be taken:

1. Ali concrete operations around the frames in the HTA-1 drywell wall have been stopped.

2. The welding and nondestructive testing performed by Atlas on all remair.ing frames which have not been completed and released for construction will be thoroughly inspected, examined, retested, and evaluated independent of the Atlas documentation packages.

TVA vill submit the next report en thir "bject to NRC on or before Nove=ber h, 1981.
