Nuclear Regulatory Commission Office of Inspection and Enforcement Region 1 631 Park Avenue King of Prussia, Pennsylvania 19406
Dear Mr. Grier:
WELD WIRE DOCUMENTATION 10CFR50.55(e), PCfrENTIAL SIGNIFICANT DEFICIENCY NO. 1 AND 2 UNITS HOPE CREEK GENERATING STATION On August'31, 1979, a verbal report was made to Region 1, Office of Inspection and Enforcement representative Mr. L. Narrow, ad-vising of a potential significant item regarding a discrepancy in the procurement of weld wire.
This verbal report was provided in accordance with'the provisions of 10CFR50.55(e).
Supplemental information was submitted in writing to Region 1, Office of Inspection and Enforcement on September 26, 1980, January 18, 1980 and March 14, 1980.
The following information is a final report concerning Pittsburgh Des Moines' use of 8018-C3 weld filler metal.
The filler metal was used in post-weld, heat-treated weldments for NF applications, but was tested for only the as-welded condition.
The results of the investigation of the heats of filler metal follows:
A total of four heats of filler metal are involved:
I.D. A 2998 I.D. A 2138 I.D. A 3297 I.D. A 8913 I.D. A 2988 - Tests qualifying this heat in the-post-weld, heat-treated condition were performed by the electrode manufacturer.
I.D. A 2138 & I.D. A 8913 - Full-thickness coupons were removed from completed welds in the post-weld, heat-treated condition and were tested.
The results indicate that the filler metal meets ASME code and design specification standards, 8 C d Sc 7 0 5~ S 9 s
e
Boyce H. Grier 5/2/80 I.D. A 3297 - Although tests on this heat of weld filler material proved to exceed the required tensile strength, the welds con-taining this heat have been totally removed.
The design deficiency which led to the procurement of weld filler metal which was not tested in the post-weld, heat-treated condition has been corrected.
As reported in the January 18, 1980 interim report, PDM has issued a new electrode specification, ES-7.5.2, Rev. A which requires testing of E8018-C3 filler metal in both the as-welded and the post-welded, heat-treated condition.
Attendant PDM welding procedures WPS 70-71, Rev. A, WPS 70-72, Rev. B and WPS 73-73, Rev. H have been revised to reflect the specification requirement.
Should additional informatir,n be desired, we will be pleased to further discuss it with yot.
Very truly yours,
