Exit Interview
The inspection scope and findings were summarized with the Site Project
!!anager on August 7,17, 21 and 28,1981.

Licensee Action on Previous Inspection Findings i
(0 pen) 518, 519, 520, 521/81-12-01 Discrepancies in Documents Controlling Handling of Nonconformances.
The inspector was informed that discussions are continuing between construction site personnel and Knoxville QA concerning revision of QA documents and/or construction engineering procedures C. E. P.15.01 and C.
E. P.15.03 to clarify authorities and procedural steps for authorzing handling of disposition of nonconformance to be repaired or use as is.
(Closed) Violation:
518, 520/80-24-01 Failure to Identify Cause and Take Adequate Corrective Action on NCR HNPA-114.
The licensee's initial response of February 6,1981, described steps taken to insure identification of "cause" and inclusion of " action to prevent
-
recurrence" on all open and future NCRs. The inspector has verified that this is being done.
The licensee's final response dated liay 22, 1981, gave additional information on Steps Taken to Avoid Further Noncompliance".
These actions

include TVA's requirement, through General Electric, that C. F. Braun, ECNs are to have the change areas circled and all ECN details be legible on the ECN prints.
4.
Unresolved Items Unresolved items were not identified during this inspection.
5.
Independent Inspection Effort The inspector made surveillance tours during which the status of project work was noted, and construction activities were inspected on nuclear
'
safety-related structures, systems and facilities. The inspection was concentrated on Plant A power block structures, but included outlying structures such as the Plant A essential service water pump stations, earthfill for the A-1 and A-2 spray ponds, the intake pumping station, and the circulating cooling water pump house.
Open Site Items Control:
Newly issued f4nconformance Reports (NCRs),
significant Quality Control Inspection Reports (QCIRs) and QA Unit audit findings were reviewed for pertinence to the inspection program and for adequacy of corrective actions.
Containment Erection: The inspector inspected final fit-up of the ninth steel ring of the A-1 containment cylinder wall and the fourth ring of the A-2 wall.
Installation of stainless cladding over vertical welds on the lower course of the A-2 containment was inspected. Joint tolerances were being assured by the steel strap inserts, and preheating was established for welding and weld repair. The applicable code for the containment welding is
the ASME Boiler and Pressure Vessel Code,Section III, Subsection NE,1974 Edition, including Addenda through S74.
Preheat adequcy was being checked by Tempstiks.
In the areas inspected, no violations or deviations wre identified.
Plant A Construction Curtailment: On August 7, 1981, the site manager informed the resident inspector of TVA board approval of construction management's construction curtailment.
The resident inspector continues to monitor for possible negative impact on quality assurance on safety-related systems and structures.
None has been identified so far.
Review of Revisions to Construction Engineering Procedures: The resident inspector reviewed changes to revised C. E. P.s received during the month as follows:
C. E. P. 8.01, R4, 8-19-81 Identification and Marking of Materials, Parts and Components C. E. P. 8.02, R6, 8-13-81 Materials, Parts and Components Control C. E. P. 8.03, R13, 8-13-81 Control of Welding Material C. E. P. 8.04, R4, 8-13-81 Notice of Substitution myr--

No conflict with quality requirements were identified by the inspector.
Tabulation and Review of Construction Deficiency Reports (50.55(e) and/or Part 21) for one-year period:
The inspector tabulated the Hartsville CDR's from July 1,1980, through June 30, 1981, and searched for any pattern which could indicate licensee quality assurance laxness in any area. No pattern was found.
Nine reports pertained to supplier deficiencies:
3 manufacturing deficiencies, 2 equipment design defects, 3 materials discrepancies, a fabricator's testing deficiency, and fabricator's QA documentation deficiency.
The Hartsville site prepared 16 NCR's (Nonconforming Condition Reports)
pertaining to defects in supplied equipment and material, and 11 NCR's for deficient vendor QA documentation.
23 written CDR's were issued during the report period for Unit A-1, and 14 were closed in this period. Hartsville issued 74 NCR's and closed 68 (36 of the newer ones, plus 32 issued prior to this period).
On August 17, 1981, there were 54 open NCR's.
Four of these were for shutdown Plant B.
This review of CDR's and NCR's did not disclose any new violations or unresolved items.

Newly Identified Items Three letters were received from the licensee in this report period.
The letter dated July 31, 1981 and received August 5, 1981:
RCIC Steam Line Break. The letter dated August 11, 1981, Environmental Qualifi-cation of NSSS Equipment to IEEE 323-1974.
This matter will be tracked under Item Number CRD81-012, -014, and -016.
A letter dated August 20, 1981, EDNES QA Training Program - A letter dated July 30, 1981, was received from Transamerica Delava Inc.,
reporting a Part 21 defect:

7.
Lakes, Dams, and Canals - Review of Work and Work Activities - Earth Fill For Plant A Spray Ponds The inspector made random inspections of earth placement, compaction and compaction testing on the earth work for Plant A essential service water sp oy ponds. Compaction testing in the field was inspected.
The laboratory test results for field samples were reviewed. Whenever the result was unacceptable, the sampled area was reworked and retested until adequate compaction was obtained. Placement and compaction of earth fill for the peripheral dikes around the spray ponds is controlled by Specification N6C-875 Earth and Rock Foundations and Fills. By observation of placement operations and by review of calculations for this and other tests, the inspector verified compliance with Specification N6C-875 and with quality control procedure QCI C-102, foendation and Fill, Earthfill Control Testing.
In the areas inspected, no violations or deviations were identified.
8.
Seismic Category I Concrete Forming, installation of rebar, positioning of embedments, placements and post placement curing were inspected as work progressed in the Plant A Containments, fuel buildings, auxiliary buildings, control buildings, essential service water pump houses, and intake pumping stations.
Specific
,
placements inspected included pour AID-1A,1B,1C totaling 1,840 cubic yards for lower section of the foundation of diesel generator building DG Division 1-1, pour AIA-16H of 88 cubic yards in the steam tunnel wall of the A-1 auxiliary building, and placement AIF-18E,18F,15G in the west wall of the A-1 fuel building.
Placement of concrete for seven deep electrical conduit manholes in the Plant A spray ponds fill were inspected. Additional inspections were made of installations of rebar for the A-2 weir wall and for the 12-foot thick floor pad between the A-2 RPV pedestal and the weir wall.
The stainless steel liner for the weir wall was having its top flange jacked into position.
During inspection of activities for structural concrete in these areas, the conformance with the requirements of C. F.
Braun Specification 300-01, Revision 8, " Concrete", TVA Construction Specification G-2, QCI C-201, Rev. 4, and CEP 9.02, Revision 5, was verified by the inspector.
