- Attended exit-interview 2.
Exit Interview The inspection scope and ~ findings were summarized on January 7,1982,'with those persons indicated in paragraph 1 above. The action taken on previous inspection findings and licensee identified items which were reviewed and closed this inspection were discussed with the licensee.

- Licensee Action on Previous Inspection Findings
'
a.
(0 pen) Violation (50-416/81-20-02) Inadequate Inspection Activities.
The. licensee is still in the process of providing assurance that final inspections of items with locking tabs will be conducted prior to operation of the equipment involved.
There is also the question of whether the tab must always be bent along one' flat of a nut or whether it can tue bent over a corner to contact two flats. This item will'be reviewed again on another inspection.
.
b.
(Closed) Unresolved Item (50-416/81-11-03) Visual Examination of Pressure Retaining Bolting For Preservice Examination is Questionable.
-
The licensee has identified which pumps, valves, and flanges contain pressure retaining bolting subject to the preservice and inservice examinations of ASME Section XI. A review of vendor and fabricator records has provided certification that the bolting materials involved have been nondestructively examined at some point in the history of the part involved.

(Closed) Unresolved Item (50-416/81-40-01; 50-417/81-17.-01) UT Weld Volume Coverage When Performing Full Vee-Path Examinations.
The PSI /ISI contractor has changed the calibration procedure _ to clarify the requirements for 12/8 THS V-Path calibration. The procedure change has been approved by the licensee's ISI coordinator.
d.
(Closed) Unresolved Item (50-416/81-40-02; 50-417/81-17-02) Qualifi-cation of Ultrasonic Indications as Geometric Reflectors. The licensee and PSI /ISI contractor have reviewed the fabrication records (including
radiographs) for all welds which were suspected' of having geometric
-
. indications. The procedure for evaluation of UT indications has been
-
clarified to require this type of review.
4.
Unresolved Items Unresolved items were not identified during this inspection.
5.
Independent Inspection a.
The inspector conducted a walk-through inspection of the Units 1 and 2 auxiliary buildings to observe housekeeping and protection _of installed safety related equipment. Unit I appeared to be moving steadily toward operational status with construction equipment and debris being removed and areas being cleaned and painted in preparation for turnover. The Unit 2 areas show the normal weathering that is to be expected for_ a project which has been delayed as long as it has. Most areas will require special clean-up and evaluation prior to renewing the' con-struction of.this unit.
There were no violations or deviations in this area of the inspection.
~
b.
Structural Integrity Test (Unit 1)
The inspector attended a meeting between the licensee and representa-tives of the structural integrity test (SIT) contractor. This meeting was to present the preliminary results of the SIT and the integrated leak rate test.
The results were presented in an informal basis in that the contractor asked for a post-test calibration check of the extensometers used
-
during the test. ' The final report will be prepared after.this cali-bration check and the final review of all data.
There were no violations or deviations in this area of the inspection.

~
mentation showed that three nonconformance reports (NCR 5156, 5157 and 5158) (representing a large number. of hangers to be reinspected.and repaired if necessary) are still open. The inspector was informed that the work on the outstanding NCR's was expected to be finished by.the end of January.
