Response to NRC A'395/78-1 Repus-f (3

l Gentlemen:
1 SCE&G has evaluated the item of non-compliance identified as 78-16-01 in your report 50-395/78-16 and has the following response.
In accordance with your wishes, we have included an explicit consideration of cause.
i i
1.
Cause i
a) The failure to magnetic particle inspect each k." and final weld over 3/8 inch thickness, has been evaluated by SCE&G/QC with the following results:
QC Inspectors have been accustomed to finding NDE re-J l
h.
quirements detailed on the Construction drawings. The drawings in this case specified only MT and the procedural l
requirement of FQCP 6.1.5 to perform volumetric MT when -
MT was specified on the drawing was overlooked.
l b) The missing welder identification stamping for bracket to beam support veld of platform XAA-1A-AH has been evaluated l
by our constructor and SCE&G/QC with the following results:
j 1
The welder failed to stamp his identification number adjacent to the weld. This is believed to be an isolated case. This l
welder has since been terminated because he was not ameniable I

'o to following instructions from^ Supervision or the proce-dures. Welding Supervision f ailed to insure that the weld had been stamped per WE-II-03.
At the time of construction of platform XAA-1-AH, (Fall 1977) structural steel welding was under supervision of the Ironworkers.
a',
'[k At the time of the inspection, SCE&G/QC was not procedurally required to check for physical ID Stamp on weld.
Checks
- c vere made to certify that the welder was qualified for the l<
particular type of welding that he was performing.
l,.:
2.
Immediate Corrective Steps Taken and Results a) Beam to containment welds on beams 4Bil and 4B8L were confirmed to have had a properly conducted final MT inspection conducted and properly documented.
In addition, a visual reinspection was conducted on these welds.
A review of the specification and a discussion with the Architect / Engineer revealed that the requirement to per-form VMT when MT was specified was intended to apply only to the fabrication specification.
b)
In relation to welder identification stamping for beam 4B8L, identification has been stamped adjacent to the weld on 10/18/78. Welding supervision was not responsible for the inspection of structural steel welding prior to February 1978. This was changed in February 1978 with the creation of Craft 65. Craft 65 is in the process of inspecting all welds male on platform XAA-1A-AH to insure that welder identification is stamped on all welds. This action is being verified by SCE&G/QC and QA.

Corrective Steps Taken to Avoid Future Noncompliance
()
a)
In relation to the failure to conduct volumetric MT, with Engineering concurrence, FQCP 6.1.5 was revised to delete j
the requirement for volumetric MT of all welds over 3/8".
Inspectors have been cautioned on the importance of following all Procedures.
b)
In relation to the failure to stamp beam 4B8L - A section on the stamping of welds is being added to the indoctrination
{
and training program for new hire welders. Welding supervision u

In addition, FQCP 6.1.2 has been revised to l
