The following discrepancies were found:
(1) Weld HP-16. The film package has line #1HP03A14 and the
radiographic (RT) report has HP08C3.
It was not known
which is the correct line number.
-(2) Weld FC-46B. In June 1977 there was a repair made and one
area was radiographed as an information shot.
In June 1980
.the entire weld was re-radiographed again with the repair
area not being stated as an R1 on the radiograph or stated
as a repair on the June 1980 RT report.
(3) 1 Weld HP-15. -The-original RT report states that three areas
are to be, repaired but there are no original radiographs.
There is another.RT report that states five areas are
repaired along with radiographs.

(4) Weld FWK-31. There are penetrameters in the area of interest
across welds in all radiographs taken.
The inspector made an inspection on November 8-9, and
December 12-13, 1978 (Report No. 358/78-30) and found several
discrepancies in radiographic techniques and reports that resulted
in an item of noncompliance. During a September 1979 inspection
(Report No. 358/79-17), the inspector found several more dis-
crepancies during his review of licensee actions. The licensee
then hired NES to review radiographs and reports for turnover
prior to operation.
NES started the review October 1979 and
completed April 1980. Radiographs of 2390 welds were reviewed,
958 radiographic reports had discrepancies, 543 welds had
unacceptable radiographic technique problems and 14 welde had
defects.
The licensee informed the inspector that the above 20 welds are
part of the 2390 welds that had received a final review by NES.
The discrepancies identified during the inspector's review of
the above field weld packages are considered a repeat item of
noncompliance (358/81-03-01).
b.
A Henry J. Kaiser Company Radiographic Report Form has been used
since radiography has been performed on site.
In the lower left
hand corner of this form, there is a block stating "MTL Approval"
(Magnaflux Testing Lab). This block was used for MTL approval
while the lab was on site and the MTL approval block continued
being used when NES arrived on site. NES is not stated any place
on the radiographic report form. On the radiographic film, NES
is part of the identification. The licensee informed the inspector
that all forms that have been used by NES will be changed from MTL
to NES and all future forms will state NES. This is an unresolved
item. (358/81-03-02)
-Except as noted,' no items of noncompliance or deviations were
'
identified.
-Unresolved Matters
Unresolved matters are items about which more information is required in
order to ascertain whether they are acceptable items, items of noncom-
pliance, or deviations. Unresolved items disclosed during this inspection
are discussed under the paragraphs " Licensee Action on IE Bulletins" and
paragraph 2b.
