SUMMARY
Inspection on May 20-23, 1980
Areas Inspected
This routine, unannounced inspection involved 27 inspector-hours onsite in the
areas of steel structures and supports - observation of welding within contain-
and review of welder qualification records (Units Al and A2); followup of
ment
a licensee identified item (50.55(e)) (Unit B1); followup of inspector identified
items (Units A1, A2, B1 and B2); followup of noncompliances (Unit A1); and house-
keeping and material storage (Units Al and A2).
l
Results
Of the five areas inspected, no items of noncompliance or deviations were identified
in four areas; one item of noncompliance was found in one area (Infraction 50-518/
80-09-01 - Inadequate measures to control storage and preservation of material and
equipment, paragraph 5.b.) .

Exit Interview
The inspection scope and findings were summarized on May 23, 1980 with
those persons indicated in Paragraph I above. The noncompliance described
in paragraph 5.b. was discussed in detail.

Licensee Action on Previous Inspection Findings
a.
(Closed) Infraction 518/79-24-01, " Excessive Reinforcement on RPV
Pedestal Weld".
TVA's letters of response dated December 6, 1979 and
January 18, 1980 have been reviewed and determined to be acceptable by
Region II.
The inspector held discussions with welding QC personnel
and examined the corrective actions as stated in the letters of response.
The inspector verified by observation that the excessive weld reinforce-
ment condition had been corrected. TVA actions are considered satisfac-
tory.
b.
(Closed) Deficiency 518/79-24-02, " Heat or Lot Number not Documented
on Welding Material Requisition".
TVA's letters of response dated
December 6, 1979 and January 18, 1980 have been reviewed and determined
to be acceptable by Region II. The inspector examined the corrective
actions, as stated in the letters of response, which included review

g
t
of Rev. 10 to TVA procedure CEP 8.03 issued 11/28/79 which deleted the
unnecessary requirements to include heat or lot number on welding
material requisitions. TVA actions concerning this item are considered
satisfactory.
c.
(0 pen) Unresolved Item 518, 519, 520, 521/79-28-02, " Welder QA Training
Program". This item concerned the fact that a formal welder QA training
program was required at Hartsville and needed to be verified by NRC.
The inspector reviewed the initial formal training program for welders
initiated in February, 1980.
The inspector considers this initial
program to be adequate. However, a complete training program should
provide for periodic updating and retraining when specific problem
areas are identified. Until these additional Provisions are provided
this item will remain open.
d.
(0 pen) Unresolved Item 518, 519, 520, 521/80-07-02, " Unavailable
Welding Filler Material Documentation". This item concerning the fact
that certification and receiving inspection records for four heats / lot
of filler material were not located during a Previous NRC inspection.
Site personnel indicated that the records had been apparently misplaced
and three of the four records had been located. The inspector reviewed
these three records. Site personnel stated that certification for lot
no. 9330 B1 also certifies for the missing lot no. 9330 Al and that a
letter war being forwarded by the vendor stating this. Until certifi-
cation for lot no. 9330 Al can be verified this item will remain open.

Unresolved Items
Unresolved items were not identified during this inspection.
5.
Independent Inspection Effort (Units A1, A2, B1 and B2)
a.
The inspector conducted a general inspection of the site including
storage areas for all Units; the fuel, auxiliary and reactor buildings
for Units Al and A2; the boilermaker fabrication shop and the pipe
fabrication shop to observe construction progress and construction
activities such a welding, housekeeping and material storage. Speci-
fically observed during this inspection was intermediate welding of
Class 3 pipe weld no. Al-FFCO212001.
b.
On May 23, 1980 during inspection of the Unit Al auxiliary building
!
the inspector observed numerous safety-related piping subassemblies in
,
direct contact with wet floors or standing water. Examples are Unit
l
Al subassembly numbers 17AB-ESW-145-1, 17AB-ESW-74-1, 17AB-ESW-353-14,
17AB-ESW-68-1, 17AB-ESW-143-2, 17AB-RHR-6-5, 17AB-RHR-7-1, 17AB-RHR-
,
l
15-4, 17AB-RHR-21-7, 17AB-RHR-34-2, 17AB-RHR-72-1 and 17AB-SPCU-7-4.
l
The inspector also observed 24-inch motor operated gate valve No.
E12F105 unprotected and without unifrom heating and temperature control.
!
The TVA valve list requires Level B storage for the above valve.
-
Procedure CEP 13.02, key. 3 requirements for Level B storage include
!
protection from the elements and uniform heating and tempeature control.

Site procedures M401, Rev. 5 and M402, Rev. 4 covering storage of
stainless steel and carbon steel piping respectively require Level D
storage. Procedure CEP 13.02 requirements for Level D storage include
cribbing or equivalent to allow air circulation and storage in a well
drained area. The piping storage procedures M401 and M402 do not,
however, clearly address in-plant storage and have been applied by
site personnel only to designated storage areas.
In addition, the
site did not have a procedure requiring surveillance of in plant
storage. This is in noncompliance with Criterion XIII of Appendix B
to 10 CFR 50 which requires that measures be established to control
the storage and preservation of material and equipment in accordance
with work and inspection instructions to prevent damage or deterioration.
This is an Infraction 50-518/80-09-01 - Inadequate measures to control
storage and preservation of material and equipment.
No items of noncompliance or deviations, except as identified in paragraph
5.b., were identified.
6.
Licensee Identified Item (50.55(e))
(Closed) Item 50-519/80-03-01 - Unacceptable Drywell Vent Structure RT's.
This item concerned the fact that some radiography performed by a vendor
for weld buttering of the Drywell Vent Structure (DVS) was improperly
Performed and some radiographs containing rejectable defects were accepted
by the vendor. The inspector reviewed TVA's proposed actions concerning
this item described in TVA reports submitted on February 15, 1980 and
March 31, 1980.
TVA proposed actions include repair by excavation and
rebuttering and complete re-radiography of vertical butt welds, and, for
T-welds, repair by excavation and rewelding at time of installation and
inspecting in accordance with original specifications. Radiography of the
T-welds is not possible and not required by the specification. TVA is
using the original vendor radiographs for repair evaluation for both weld
types. The inspector reviewed the applicable specification and reviewed
l
radiographs for welds 7-1-3, FJ-5; 1-1-3, FJ-1 and 2-1-3, FJ-6 to verify
l
that vendor radiographs were of sufficient quality for repair evaluation.
l
The above repairs are in progress. TVA actions concerning this item are
considered satisfactory. It is noted that this DVS ordered for Unit B1 is
now being installed into Unit A2.
7.
Steel Structures and Supports - Observation of Welding Activities Within
Containment (Units Al and A2)
The inspector observed in-process welding activities of containment struc-
tural field welds as described below to determine if applicable code and
procedure requirements were being met. The applicable code for Containment
Shell (CS) welding is the ASME B and PV Code Section III Subsection NE
i
l
(74S74).
The applicable code for Drywell Vent Structure (DVS) and Wier
Wall (WW) welding is AWS DI.1 (Rev. 2-74). The following welds were exam-
ined in process to determine conformance to requirements in the areas of
field documentation, weld identification, availability of welding procedures
!
!
and drawings, weld procedure used, technique and sequence base metal, filler
metal, joint geometry and alignment, preheat, equipment condition, interpass
temperature, removal of temporary attachment, and inspector qualification:

cation was in accordance with code requirements (Applicable codes are
identified in paragraph 7).
