Independent Inspection Effort a.
Plant Tour The inspector performed a general inspect ton of Units A1, A2, and B1 to assess construction progress and/or. mot hballing activities under way in the three units.. In addition the inspector spot checked completed welds for workmanship quality, cleanliness around work areas, house-keeping and control.of weld electrodes, used/ unused, around these areas.
b.
Reactor Pressure Vessel (RPV) Lift (Unit A1)
The inspector observed the RPV lift which commenced on December 12, 1979. The vessel was lifted and set in the upright position where workman removed the protective support skirt. The RPV remained in this position through the duration of this inspection.
c.
Pedestal Bearing Plate Machining
.The inspector discussed / observed machining of the bearing plate with the licensee's cognizant engineer. Mechanical problems and operator error-resulted in a machining gouge in one section of the plate that subsequent material removal deminished but did not remove completely.
-
Plans called for removing approximately 0.080" of material from the high' spot of the pedestal caused by weld repairs on the pedestal wall.
- The licensee represent 3tive stated that the - four (4) inch minimum plate thickness would not be violated.
d.
Welder Qualification and Training - Inspector Follow-up Item (IFI)
518, 519, 520, 521/79-12-04 (Closed)
In response to inspector follow-up item 50-518, 519, 520, 521/79-12-04,
"QA Training program for welders", the inspector reviewed TVA's QA Program Manua',, Issued on May 1, 1979, which provides for the training of welders and welding operators under section TL-201. The section requires these craft to receive 16 classroom hours of instruction on weld procedure parameters and applications; inspection points and quality levels; gealificatica mainte24nce; weld metal control and qualification test. Discussions with TVA site management disclosed this program had not been implemented as yet.
In response the inspector stated that this prograt was of utmost importance to weld quality and expressed concerns over managements failure to implement it in a timely manner even thougt IE:II had brought it to their attention as an IFI'79-12-04. -TVA's site management. stated that these concerns-were. understood and thac the training program would be ~ started by February 1,1980. The inspector stated this matter would be closed as-an IFI and would now be identified as unresolved item 518, 519, 520, 521/79-28-02, Welder QA Training Progra &

Steel Structures and Supports - Observation of Welding Activities within
~
Containment - (Unit A1)
a.
-Welding inside containment at the time of this inspection was centered around the containment steel structure (repairs) and on the dry wall vent structure (DVS).
C. F. Braun specification number 200-09, Revision 5, S/9/78 provides' specific requirements relative to fabrication inspection and. testing of the DVS.
Codes controlling these. activities included ASME sections III, (74,S74) Division 1 NE-5100, NE-5300,Section V and IX; AWSDI.1-74. The applicable code for. containment (CS) welding, as required.by Braun and Company specification 300-13,.
-Revision 7 and TVA " Code of Record" letter dated October 23, 1978, is the ASHE Boiler and Pressure Vessel Code,Section III, Division 1, Subsection NE, 1974 Edition, Summer 1974 Addenda for the shell and Division 2, Subsection CC, 1975 Edition for the bottom liner.
Observation of field welding activities included, where applicable, the following areas; weld identification and location, joint preparation and alignment, evidence of QC verification, use of specified weld procedure, welder qualification, use of specified weld material, use
-
of specified preheat, control of interpass temperature, cleanliness, removal of are strikes and weld spatter. The following activities were observed:
(1) JOINT' REPAIR (DVS)
Vertical Seams DVS00009 DVS00007 DVS00035 l
(2) JOINT WELLED OUT (DVS)

when'the welder _was not ready to start welding. Moreover the inspec-
- tor' found the. welder.p~reparing (grinding and brushing) the seam for
- welding. The. inspector found the weld area to be still warm to the
' touch Lbut nowhere 'close to the required 150'F preheat temperature.
Standard Operatidg Procedure. SOP-34, Rev. 1 " Weld Inspection Documen-
,
tation",. paragraph;6.3 requires the welding inspector to verify that~
t the proper preheat temperature. is being used'before welding. commences-and to. document the inspection on the appropriate record. Discussions
'with ' craft disclosed that preheat is applied; to the weld at a time when the QC inspector is available to perform the inspection even though the welder.may not be ready to commence welding. However, the inspector was assured that preheat was raised back.to the required level before welding; commenced. The inspector discussed these findings with site welding QC supervision explaining that convenience and expediency was not the intent of QC inspections and that even though the inspector.had no reason to doubt that the proper preheat tempera-ture was attained prior to welding, the validity of the inspection was lost if it was not performed in the proper time frame. Moreover the
,.
inspector pointed out that conducting inspections in this manner indicates a possible breakdown in the QC inspection program in this area. The licensee took immediate corrective action on this matter.
.
Failure to accomplish activities in accordance with code and/or proce-
~
,
dural requirements is in noncompliance in the infraction category with Criterion V of Appendix B to 10 CFR 50.

This-finding was' identified as item 518/79-28-01 QC Inspection - Preheat.

Steel Structures and Supports - Visual Examination of Welds The QA/QC records of completed DVS weld #DVS00017 were reviewed in order to
"'
determine.whether. visual and dimensional inspections had been performed,
~
weld appearance met acceptance standards and the record package was complete, s
a'ecurate and retreivable.
In addition the inspector reviewed the radiogra-phic film of.this weld for film and radiographic.qualtcy. Within the areas inspected.no items of noncompliance or deviation were identified.
