~ ~, t Re: Turkey Point Units 3 5 4 Docket No. 50-250 and 50-251 IE Ins~ection Ressort 81-26 The requested addi ti onal in format i on on welding terminology and peening i s provided as follows:

Manual vs. Automatic/Machine Weld~in Bechtel has two series of welding procedure specifications (WPS's); one for manual welding, and another for machine and automatic welding. The first series specifications do not contain specific statements to the effect that they are for manual weldi,ng; however, from the data contained within them, it is reasonably obvious that they address manual welding only. The second series specifications are more specific and do contain statements that they are for machine/automatic welding.

The simplest method of differentiating between manual and machine or automatic WPS's is in the WPS designation. The way that WPS's are designated is described in Welding Standard GR-1, which is normally maintained as an internal document. GR-1 points out that automatic welding procedures contain the lower case 'a 'n 'o'n the WPS designation, and machine welding procedures contain the lower case the WPS designation.

By inference, WPS's with designations which contain neither 'a'or 'o're manual welding procedures. This response was considered acceptable by the National Board of Pressure Vessel Manufacturers during an audit at Bechtel's San Francisco office.

Peening It is Bechtel standard practice to prohibit the use of peening.

Paragraph QW-410.26 of ASME Section IX is listed as non-essential variable for all commonly used welding processes. This paragraph specifically addresses "the addition or deletion of peeni ng", which has been interpr eted to mean that peening needs to be addressed in the WPS's or GWS's only if it is added to or deleted from a WPS or GWS. Since this has never occurred, they have not felt the need to address peening.
