CITY AND COUNTY Of SAN )

FRANCISCO )

The above being duly sworn, deposes and says:

I, Richard D. Etzler, an Field Construction Manager for Diablo Canyon construction activities at the jobsite. I have held this position since Septenber 1978. Prior to ny duties as Project Superintendent, I was Resident Mechanical Engineer. From 1971 to 1977 I was a Field Engineer and group leader who reported to the Resident Mechanical Engineer.

I have carefully read the affidavits of Charles Stokes dated Novenber 17, 1983, and February 8,1984.

- N I.t is alleged that:

QCinsfiectorswerenotconsistentlyqualifiedtotheAWS code,Jthat_none of.them had been issued copies of that code, andithat the inspectors could not read weld symbols on design drawings. (Stokes, 2/8/84, p. 8, para. 19)

1. Contrary tosthe. implication of Mr. Stekes, Pullman QC inspectors

~

are all qualified and certified in welding procedures and symbols pursuant to Pullman Pewer Products Quality Control Procedures which are consistent with ANSI Standard N45.2.6. It has'always been the case that, as part of,this qualification and certification program, al.1 quality control welding inspectors have' received training in .iWS symbology'. Such training includes mandatory reading assignments and testing.in weld symbols. -

2.'The,AN3 symbols" code"referredtobyMr. Stokes (AWS2.4,

' ~

Symbols for Welding and Non-Destructive Testing) is not a code ,

out a standard. This document is not required to be issued to Pullman QC:inspet. tors by the'HRC, PGandE specifications, or industry code requirem nts, and is:not the sole reference on AWS welding symbols available at the Diablo Canyon site. Various handbooks and other standards contain such information.

l 3. While not all-Pullman OC inspectors are certified to the AWS code, many, on their own, have obtained this supplemental

, _ professional credential. AWS certification is not required by

\

the NRC or PGandE specifications.

, . It is alleged that:

Welders did not have Pullnan Power Products procedure ESD-223 or welding procedures. (Stokes, 2/8/84, p. 8, para. 17)

4. . ESD-223 is a Pullman Power Products procedure based upon PGandE Specification 8711, design docunents, codes, standards, and manufacturing reconnendations. This procedure provides detailed criteria for installation of pipe supports. Controlled copies of ESD-223 are issued to field QC ana engineering personnel and are available to the craftsnen through forenen, general forenen, superintendents, field engineers, and QC inspectors. Current controlled distribution of ESD-223 is over 300 copies.

5. For the nost part, ESD-223 is not a docunent utilized or needed by .

craftsmen, such as welders. Typically, for a pipe support installation, a Pullman Power Products field engineer reviews the design documents and, utilizing ESD-223, prepares a process sheet. The process sheet specifies the weld procedure to be used and notes specific requirements such as preheat, interpass tenperature, and electrode type. The process sheet and the design docunents which are given to the welder provide all the necessary infornation to do the job correctly.

6. The tern " weld procedure" refers to a process as well as a specific docunent. In order to work as a welder at Diablo, each welder nust pass a performance qualification test for each weld process he will be using in the plant. This qualification and a nonitoring progran by Quality Control 3

ensures that the welder is familiar with the paraneters and essential

variables required by that welding procedure. Once the welder has been qualified and certified to weld to a specific procedure, it is so noted on the Welder Performance Qualification Card, which is in each welder's possession. General welding information is also included on the back of this. card. The Weekly Weldei s Qualification Status, a document summarizing the qualifications of each welder, gives additional information about each welding procedure with respect to base material, root type, weld process, and filler metal. Each welder has access to this document through his foreman.

7. Before a welder may work.on a specific selding cssignment and prior to obtaining weld rods, the Quality Assurance representative verifies his qual'ification to do the weld procedure s'pecified on the welding rod requisition. Only after this verification is filler material issued to the craf tsman. In addition, all welds 4re inspected by Quality Control to ensure that they nbet criteria specified in ESD-223.
