Exit Interview The inspection scope and findings were summarized on June 26, 1981 with those person,s indicated in Paragraph 1 above.
The violation and unresolved item described in paragraphs 5.c. and 12.b., respectively,'were discussed in L
detail.
In addition, the inspector held discussions with Mr. W. O. Henry,
'
QA Manager, Technical Services Division and Mr. J. R. Wells, Corporate 0A Manager on. June 30, 1981 and July 1, 1981, respectively, concerning i'
violation described in paragraph 5.c.
The inspector described the violation in detail and indicated that further mar.agement action appears necessary i
.
. -
.
.
concerning evaluation of the specific nonconforming item and concerning prevention of further inadequate evaluations of nonconfonning items.
Mr. Wells indicated that examination of this item would begin immediately.
3.
Licensee Action o-Previous Inspection Findings (Closed) Unresolved Item (413, 414/81-04-01) - Missing radiographic technique records.
The inspector verified that the radiographic technique records were available in the Corporate QA Records Vault.
(Closed) Unresolved Item (413, 414/81-05-03) - Deteriorated pipe caps.
This item concerned the fact that caps on piping spools in the storage laydown area were in the process of deteriorating due to exposure to sunlight.
The licensee has made personnel aware of this problem and has instituted an inspection program to look for deteriorated caps. The inspector verified this program implementation by reviewing the procedure change, Rev. 9 of CP-170, and by observation of the laydown area.
(Closed) Violation (413/81-06-03) - Failure to document corrective action concerning inadequate design of a hanger. Licensee actions concerning this
item have included implementation of a Design Engineering Department procedure for handling of nonconformance (PR-202), revision of the drawing for the affected hanger and review of drawings to determine that no similar inadequate design has been implemented. The inspector reviewed documenta-tion of the above actions and considers these actions to be satisfactory.
4.
Unresolved Items l
l Unresolved items are matters about which more information is required to l
determine whether they are acceptable or may involve noncompliance or deviations. A new unresolved item identified during this inspection is j
discussed in paragraph 12.b.

5.
Independent Inspection Effort I
l a.
The inspector conducted general inspections of site work and work activities and observed equipment protection / storage and housekeeping l
in the auxiliary building, containment buildings, pipe fabrication shop
!
and storage areas.
'
The inspector reviewed numerous Nonconforming Item Reports (NCI's) to b.
determine if nonconforming conditions were adequately described, dispositioned and evaluated in accordance with NRC and licensee procedure requirements.
c.
On June 18, 1981 the inspector reviewed NCI No.11746 concerning inadequate weld root conditions for Wald Nos.1NV343-1, INV 344-1 and 1NV 351-1. Disposition of this NCI was to repair the three listed welds. A determination of the cause of the condition and evaluation of the possible generic implications was not performed.

L procedure Q-1 does not appear to provide' adequate guidance on handling-of NCIs to verify that the cause.of the condition is determined and corrective action _is taken to preclude repetition. This is Violation
.413, 414/81-14-01 - Inadequate procedure to assure adequate evaluation of.a nonconforming condition.
.No' violations or deviations, except as described in paragraph 5.c., were-identified.

6.
Storage. Inspection a.
Site storage requirements are defined via various documents such as purchase documents,. requisitions and documents intended specifically for this purpose such as Duke Form 302.2, Duke Form P3A and NSSS Lists.
Storage is controlled on site via QA procedures P-1, Rev. 20, Receiving l
Inspection and P-3.- Rev.12, Storage Inspection.
In addition, the~
l requirements of ANSI N45.2.2, Packaging, Shipping, Receiving, Storage l
and Handling of Items for Nuclear Power Plants have been adopted by Duke.
!
j The inspector observed storage of numerous components, equipment and
construction materials for conformance to applicable requirements.
Included in this observation were the Unit 2 reactor vessel internals, hydraulic steam generator snubbers for Units 1 and 2 (Note:
This equipment was in the process of being reworked per. NCI 11980), piping spools (all classes), electrical cable and electrical components.
No violations or deviations were identified.

j-Related Pipe Support and Restraint Systems Installation (Unit 1)
a.
The applicable code for safety-related support and restraints instal-lation -is the ASME Boiler and Pressure Vessel Code,Section III, Subsection NF,1974 Edition plus addenda through summer 1975. The inspector observed prefabrication in process: for hanger Nos.
1-R-WL-D114 and 1-R-ND-0200 for conformance to requirements in the-areas of drawings, use of specified materials, in process documentation and control of welding.
No violations or deviations were identified.
