SNRC-390 Mr. Boyce Grier May 16, 1979 Page 2 Our investigation is continuing to determine whether welding fittings (elbow; tees, reducers, etc.) manufactured using Youngstown Welding and Engineering Company welded stainless steel pipe, as starting raw material, have been used at the Shoreham site.

This investigation is time consuming cs certi-fied material test reports for welding fittings generally do not identify the manufacturer of the starting raw material used by the fitting manufacturer.

Also, welding fittings are often procured from material suppliers rather than directly from the fitting manufacturers.

In these cases, information must be obtained from the vendor's subvendor.

The results of the aforementioned investigation will be forwarded to you when available.

We will address our course of action in this regard at that time.

A full volumetric examination of each of the three previonely listed spool pieces will be performed.

This examination will consist of an ultrasonic examination of the entire weld length utilizing the acceptance criteria delineated in ASME Section III for the code class of each piece examined.

Rejectable indica-tions will be reworked in accordance with site procedures to return the pipe to code acceptability.

We trust that the above has been responsive to your request.

Should you desire additional information, please do not hasitate to contact us.

Very truly yours,
