Exit Interview The inspection scope and findings were summarized on March 26, 1982, with
,
those persons indicated in paragraph 1 above.
The unresolved item and violation described in paragraphs 6.b. and 15.b., respectively, were discussed in detail.

Licensee Action on Previous Inspection Findings
.
a.
(Closed) Unresolved Item (413, 414/82-06-01):
Verification of i
electrical cable separation. Adequate controls have been implemented
{
by the licensee, in that a final walkdown inspection is now required by
'
supplemental inspection instruction tio.19 and instructions for i
installation of cable tray barriers nave been issued.
b.
(Closed) Violation (413, 414/81-22-01):
Failure to adequately control i
power cable spacing.
Licensee actions concerning this item have included clarification of the applicable specification, reinspection
,
and correction of previously installed cables, training of appropriate

personnel and implementation of a final walk through inspection. The inspector verified these actions and considers them to be adequate.
4.
Unresolved Items Unresolved items are matters about which more information is required to determine whether they are acceptable or may involve violations or devia-tions. One unresolved item identified duping this inspection is discussed in paragraph 6.b.
5.
Independent Inspection Efforts (Units 1 and 2)
The inspector conducted general inspections of site work and work activities; observed protection and storage of mechanical equipment,
-
electrical equipment, electrical cables, instrumentation and piping; and observed housekeeping. These inspections were performed in the auxiliary building, containment buildings, pipe fabrication shop and storage areas.
No violations or deviations were identified.
.
6.
Nonconforming Item Report Review (Units 1 and 2)
a.
The inspector reviewed numerous nonconforming item reports (NCI's) to detennine if requirements were met in the areas of documentation, approvals, evaluation, justification, and corrective action.
b.
The inspector noted on fiarch 18, 1982 that NCI No.13632 identified that a Type II embedded plate lacked studs within 1" from the plate end.
Discussions with licensee personnel revealed that previous installation procedures had resulted in many Type I and II embedments which lacked the required studs within 1" of the end.
It appears that licensee personnel involved with the hanger program have recognized the problem and routinely use ultrasonic examination to determine stud locations.
It is not clear whether or not this discrepancy has been
>
accounted for during installation of other attachments to Type I and II embedments.
Until it can be determined that the stud location discrepancy has been considered for all other attachments to embedments this will be an Unresolved Item (413, 414/82-07-01): Verification of adequacy of embednents to withstand required loads.
No violations or deviations were identified.

Requirements for cable terminations are delineated in various DPC specifications and site procedures CP-388 and CQAP-M41. The inspector observed termination in progress for Unit 1 cable IVC 645 for confor-mance to requirements in the areas of cable identification, use of appropriate lugs, location of wires, cable entry into cabinets, tool calibration, and condition of wires.
b.
The inspector observed installed cables in various area in both units for protection of cable and cable trays from construction activities, securing of coiled cable, protection of cable ends, support of cable, and debris in cable _ trays.

The inspector also observed the development and evaluation stages of liquid-penetrant inspection for weld Hos. 2NI349-6 and 7.
b.
On liarch 16, 1982, the inspector observed grinding being performed on the repair excavation for weld No. INC234-12. This grinding was performed after QC inspection of the excavation and prior to rewelding.
Rewelding was completed without obtaining another inspection of the excava tion. This grinding, if allowed, would, in effect, nullify the validity of the excavation inspection.
Existing site procedures do not preclude grinding on repair excavations after inspection is performed.
Therefore, this is in violation of 10 CFR 50, Appendix B, Criterion V which requires activities affecting quality to be performed by documented procedures appropriate to the circumstances. This is a Violation (413, 414/82-07-02):
Inadequate procedure for control of repair welding.
No violations or deviations, except as identified in paragraph 15.b above were identified.
16. Safety-Related Piping - Observation of Work and Work Activities (Unit 2)
a.
The applicable code is delineated in paragraph 14. The inspector observed handling and protection of piping for fabrication of the welds listed in paragraph 14 for confomance to procedure and code require-ments in the areas of control of tools for grinding, brushing and filing; use of appropriate handling and rigging equipment; control of cleanliness; and control of cold spring where applicable. The inspector also observed machining of piping for weld Nos. 2NV64-11, 2NS37-14, 2ND9-7, 2NV186-5 and 2NV63-14 for conformance to requirements i
for handling and tool control.
No violations or deviations were identified.
