I a.
QA Systect - Welding and Piping A satisfactory quality assurance plart, which conforms to the
!
application, is being implemented by the Toledo Edison Campany
!
(TECO) for the containment spray and conponent cooling water systen.
The Class I piping is being installed by Grinnell.
Grinnell has a contract with TECO, which includes fabrication of piping spools in the Grinnell plant in I:ernersville,
,
!
North Carolina, and installation of the spools at the i
Davis-Besse site.
Although Grinnell does not presently have a "NA" stamp for site fabrication, an evaluation by the AS::E connittee, for issuance of the stang, will be made when 20%
of the piping installation is conplete.
Dechtel, acting as architect-engineer, construction manager, and quality as.surance agent for TECO, issues purchase ordern, which include the goveriting specifications, to the contractors.

-
l The same velding procedures are used by Grinnell for spool
fabrication and for site system construction.
The veld procedures and the welders are properly qualified, and
'
documentation of this fact is on file. The nondestructive test procedures and personnel are also qualified, with lists available of the personnel qualified to parform the various NDT tests.
.
Identification of weld location, procedures used, and welders is maintained by use of isometric drawings and a
!
weld data report, Forn No. FF-106A.
This form is a check-I off type, traveler sheet (initiated by the inspector and f
approved by QC) which renains with the veld and covers all phases, including visual examination of joint preparation, i
root gap, purge, aligneent, root pass, and conpleted weld.
!
The NDT required and results at various stages of the weld
O are also shown, together with identification of the NDT
!
inspector and checking QC representatives.
Preheat and post heat treatment requirenents are also shcwn and checked off on Form No. FF-10GA.
Autographic records of the required stress relief tenperature are included in the j
documentation package for each completed weld.

i l
Radiograph, magnetic particle, and penetrant testing require-l ments are shown on the veld data sheet, together uith a check-l

The original radiographic films, showing the defect, are i
included in the film package with proper identification of l
records to the weld.
Verification and acceptance of the
