- Attended exit interview 2.
Exit Interviews The inspection scope and findings were summarized with the Project Manager on October 2, 9, and 27,1980, and with the Acting Project Manager, W. R. Quinn, on October 17 and 24,1980 3.
Licensee Action on Previous Inspection Findings (Open) Unresolved Item 518, 519, 520, 521/80-15-04, Stainless Steel Tanks Lef t Open While in Storage The purchase contract and C. F. Braun specifications made no mention of storage conditions for these tanks, which were fabricated on site and left in " interim storage" at the fabrication area. TVA received the tanks per RIS&PM procedure M-705 " Atmospheric and Low-Pressure Storage Tanks (STRIDE), API 650 and 620-NON-QA". Paragraph A5.(3) instructs " Verify that the nozzles of shop fabricated storage tanks---are securely closed by blind flanges or steel plugs taped shut."
In response to questions, site QC decided that " Level D" storage was the proper classification. The instruc-tions for Level D storage do not include sealing instructions; however, the v

licensee has installed blind flanges on manways and nozzles. The inspector has verified that the closures are being maintained.
The licensee is evaluating the need to revise RIS&PM procedure M-705.
This item remains
'
open pending completion of this evaluation.
(Closed) Unresolved Item 518, 519, 520, 521/80-15-05, Maintaining Concrete Batch Plant in Correct Adjustment to Assure Correct Concrete Mix
.
The inspector has verified that the licensee has made repairs and adjust-ments to the rotating discharge. chute and to the flanged gasketed connec-
!
tions to the mixing drums.
The corrections minimize the loss of cement I
dust and water from the drums. Sources of non-mix water which could enter the mixer or the receiving truck were investigated and eliminated or the water diverted.
During recent inspections at the batch plant during operation, control of cement dust and water was acceptable.
4.
Unresolved Items Unresolved items were not identified during this inspection.
5.
Independent Inspection Effort The inspector made routine surveillance tours during which the status of project work was noted, and construction activities were inspec'.ed on nuclear safety related structures, systems and facilities.
Inspaction effort was concentrated on Plant A areas and on chair weld repairs in A-1 and B-1.
Follow on inspections of structural concrete were made in the Plant A power block structures. Forming, installation of rebar and embedments, place-ments and post placement curing were inspected as work progressed for A-1 fuel building and auxiliary building. Activities prior to placement were inspected for the A-2 fuel building, reactor shield building and auxiliary building.
All phases of concrete activities were inspected for fuel building placement AIF-22D, 22F, and 19B to elevation +7'-0".
178 cubic yards were placed on October 6, 1980, in complex forming, heavily congested with reinforcing steel and embedments.
Adequate inspection by TVA QC for these operations was verified. Concrete installation activities are controlled by C. F. Braun specification 300-01, Revision 8 " CONCRETE".
Follow on inspections were made of earthfill and compaction in the A-1 and A-2 spray pond areas and in yard areas around Plant A structures. Inspec-tions were made of placement and compactions of rock and filter materials for the Plant A portion of the rock dike South of the spray ponds.

.
.
-3-The inspector verified that earth work and rock dike placement were being performed in accordance with the requirements of TVA Specification N6C-875, R12 " Earth and Rock Foundations and Fills".
The inspector verified that required preheating was being done for welding on the A-2 reactor pressure vessel pedestal and for welding and cladding on the steel containments r.ad vent walls in A-1 and A-2 reactor buildings.
The inspector verified that wa rmed air was being circulated in reactor pressure vessel (RPV) X-20 stored in the dock area for Unit B-1 and in the A-2 RPV stored next to Unit A-2 shield building. The inspector observed sealing of ends of instrumentation tubes and control roi drive tubes on the A-2 vessel.
No items of noncompliance or deviations were identified.
6.
Licensee Identified 50.55(e) Item (Closed) 518/79-17-01, Containment Anchor Bolt Chair Weld Deficiencies Repairs to the chair welds at the base of A-1 containment were completed during this period. During this inspection period, the inspector verified that proper preheating was being performed, and that TVA-QC inspectors were checking activities and results. The second tensioning of the containment anchor bolts is in progress.
The inspector observed the operations involved in the use of the calibrated hydraulic jack in applying tension to the bolt and seating of the nut.
The inspector made two inspections of chair weld repairs underway in Unit B-1 containment (Item 519/79-17-01).
Preheating and TVA-QC coverage was verified. This item will be left open for Unit B-1 until completion of repairs.
7.
Inspector Follow Up Items (Closed) 519/80-15-02, Follow GE Evaluation of Reactor Pressure Vessel Ultrasonic Inspection. (B-1 RPV Stored at Dock)
The ultrasonic test results, indicating no problem in the areas examined, j
have been transmitted by General Electric to TVA engineering for their l
records. The inspector discussed the findings with the assistant construc-l tion engineer, STRIDE Engineering, who stated that TVA evaluation has verified acceptability.
(0 pen) 518, 519, 520, 521/80-15-06, Follow Resolution of Welding Audit Findings The findings of OEDC Audit 80-06 concerning QA-QC performance at TVA construc-tion sites have not been cleared. Revisions to the TVA QA program needed l
to clear the audit findings were reported to be in process in OEDC-QA unit, l
in Knoxville.
!
i o
'o o-4-The inspector was informed that the review of welding procedures and per-formance at all of TVA's constructioa sites by a team was not an audit but an indepth management review that was not restricted o NRC concerns.
Recommendations have been submitted to OEDC management. These are under review by OEDC management for possible changes in policies, procedures, organizational structure or personnel, with the objective of improving program efficiency in addition to meeting NRC requirements on QA-QC.
8.
Status of IE Circulars The inspector determined that the licensee has received and assigned for review the following Circulars, which are closed for record.
(Closed) IEC 80-22, Confirmation of Employee Qualifications Licensees are advised to review their employment procedures to assure verification of qualifications of professional employees.
(Closed) IEC 80-23, Potential Defects in Beloit Power Systems Emergency Generators Licensees are advised to check these units for frayed insulation on a lead between the collector rings and the field coils.
Loss of field could result from shorting of the lead.
