Repair Welding of the'Ereecency Feedwater Storage Tank
a.
The NRC inspector reviewed the following documents associated with
the repairs i.o the emergency feedwater storage tank:
Maintenance Order, Procedure M0-872077, " Weld Repairs to
.
Emergency FW Starage Tank"
Weld Design Data Form No. 872077-1
.
Weld Verification Form, Document No. 872077
.
Professional Service Industries Procedure 81-102, " Methods for
.
Radiographic Examination of Welded Joints ASME Section V"
Standing Order G-12A, " Welding and Weld Control"
.
Standing Order G-26A, " Quality Control Program"
.
The hydrostatic test pressure specified in Maintenance Order
No. 872077 was discussed with the licensee.
A procedure change was
made to ensure that the requirements of ASME Code Section XI are met
when the tank is hydrostatic tested.
b.
The NRC inspector observed the repair welding of the emergency
feedwater storage tank and reviewed approximately 25 radiographs for
repairs to the tank seam welds.

In the areas reviewed, the welding was consistent with the welding
procedure; the QC entries on the weld verification form for releasing
hold points were consistent with the status of the welding; the
welding filler materials were controlled consistent with Standing
Order G-12A; and the welders were qualified to ASME Code Section IX.
In reviewing the technique used for radiographic examination of the
repairs to seam welds G1 and G2, it was determined that film side
penetrameters were used, although the radiographic Procedure 81-102
and the ASME Code Section V required source side penetrameters.
This is an ap(parent violation for failure to follow the radiographic
procedure.
