Licensee Action on Previous Inspection Findings
+
(0 pen) Noncompliance (440/82-03-03) - Lead location markers were in the area of interest, a repair area was not correctly identified by location markers, and lack of fusion, excessive slag, and a crack were found in various welds.
(0 pen) Weld No. WN 1-1, area 20-21.
The radiographs reveal approximately
.
13 areas of lack of fusion and excessive slag.
(0 pen) Weld No. WM 1-1, area 31-30.
Repair four (R-4) radiograph was
.
not correctly identified in area repaired.
(0 pen) Weld No. WN 1-1, area 31-30, repair 6 (R-6).
The radiograph
.
reveals a crack in the wold.
(Closed) Assembly No. OM-61-21X, Wold No. B, area P-S-B on the radio-
.
graph had the lead location markers located in the area of interest which could mask a defect. This area was re-radiographed and found to be acceptable.
(0 pen) Unresolved Item (440/82-03-01) - Possible linear indication in assembly No. OM-61-17X, weld No. D, area E-F-G on the radiograph.
This area was re-radiographed utilizing very fine grain film to obtain better resolution, sensitivity, and definition in order to resolve linear indications. The radiograph revealed that the linear indications were cracking and areas of non-fusion. This item has been resolved and a NCR
_(No. T/AS0002) has been initiated.
This item will remain open until weld repair has been completed and re-inspected.

(Closed) Unresolved Item (440/82-03-02) - Possible linear indication
'
in assembly No. 0?i-61-19X, Weld No. A, area H-I-J-K on the radiograph.
Area was re-radiographed and found to be acceptable.
i (Open) Open Item (440/81-17-01) - Box beam girder welds in Unit 2
'
polar crane.
Repair welding of Unit 2 girder welds is in process and is expected i
to be completed by June 11, 1982. A UT of the Unit 1 girder welds is scheduled to be started by April 27, 1982. This UT is to be conducted on a random basis to determine if Unit I has similar defects as identi-fled on Unit 2 polar crane girder.
If similar defects are identified,
then a separate NCR will be written to identify these defects.
'
>
During repair operations of Unit 2 polar crane girder, it was identi-fled that a number of subsurface linear defects existed in shop welds.
The amount of repair work raised concerns about the overall quality of the girder assemblies. These concerns resulted in a meeting between CEI and NNI in which NNI agreed to study the problem and provide a recommended course of action for resolution. The owner concluded that a problem did exist and recommended that an informational UT be per-formed on all major structural welds in question. Joints were 100%
UT inspected with the exception of excavated joints undergoing repair
prior to the suspension of work activities. Of the approximately 100 UT reports resulting from this inspection effort, all indicated a reject disposition.

Containment Radiographic Review The above three personnel have been retained by Project Organization NDE Group to review 100% of the radiographs of Units 1 and 2 contain-ments.
An NCR has been initiated (T/AS0001). The review of the radiographs to date indicate that 62% of the welds reviewed are re-jectable. These rejectable welds pertain to the welds on NCR's No.17-152, 17-777,17-195, 17-254 and 17-268.
The review of the welds not concerned with the original NCR's indicates a reject rate
of 32%.
