Subject:

IE Bulletin No. 79-03, Longitudinal Weld Defects in ASME SA-312 Type 304 Stainless Steel Pipe Spools Manufactured by Youngstown Welding and Engineering Company R. E. Ginna Nuclear Power Plant, Unit 41 Docket No. 50-244

Dear Mr. Grier:

I In reply to Inspection and Enforcement Bulletin 79-03 concerning longitudinal welds in ASME Section IIIclass 2 pipe supplied for Palo Verde and San Onofre nuclear generating stations, Ginna Station Quality Control has reviewed the use of ASME SA-312 Type 304 Stainless Steel pipe installed in Quality Group B Systems at Ginna Station.

The results of this review indicate the following:

1.

Class 2 Stainless Steel piping systems at Ginna Station were originally designed to ASA-B36.19 and B36.10 with reference in applicable line specs to ASTM-A-312 Type 304 Stainless Steel Seamless Pipe.

2.

Stainless Steel piping installed in Quality Group B Systems at Ginna Station was identified as seamless pipe purchased from other manufacturers and not that pipe mentioned in the subject bulletin (ie., piping containing longitudinal seam welds).

At the present, there are no modifications either installed or proposed that include use of ASME SA-312 Type 304 Stainless Steel pipe containing longitudinal seam welds supplied by the Youngstown Welding and Engineering Company.

Very truly yours, r

L. D. Whit, Jr.
