ITEM (81-00-02):
Horizontal crack in
primary containment liner base ring T-weld.
Ultrasonic examination
using the dual
70o pitch-and-catch
technique
has
shown that the long,
continuous
crack which was found in a similar joint at the River Bend
Project did not exist in this weld at Nine Mile Point, Unit 2.
Other
small indications were discovered
and these
weld indications
have
been
repaired.
The inspector
reviewed both the ultrasonic test reports
as
a result of the pitch-and-catch
technique
and the nondestructive
examination reports required
as
a result of the repairs

who performed the test were originally certified in
accordance
with SNT-TC-1A for leak testing.
Based
on the acceptability
of the test data,
as determined
by a certified Level II to SNT-TC-lA
for pressure
decay testing,
and the similarities in qualification
requirements
for leak testing
and absolute
pressure
decay testing,

A g.
C. welding inspector promptly verified that the
correct
spool
pieces
had
been
welded together,
and the engineering
department
was advised to check that all weld data reports listed
the identification numbers of the pieces to be joined.

The inspector
reviewed the following procedures
to assure
compliance
with Stone
5 Webster Specification,
NMP2-7201, Field Storage,
Handling,
and Issuance
of Welding and Brazing Materials,
Revision 1, dated
January
19,
1981
and to determine that measures
had
been established
for the identification and control of covered electrodes, filler wire,
and consumable
inserts:
ITT Grinnell, QCF-5.1, Welding Quality Assurance
Material Control,
Revision 4, dated April 2, 1980.
ITT Grinnell,
FQC 5.1-1-2, Control, Storage
and Disbursement of
Welding Materials,
dated August 26, 1980.
ITT Grinnell,
FQC 7.1-1-5, Calibration of Portable
Hot Boxes
and
Stationary
Ovens,
dated
September
19, 1978.
ITT Grinnell,
FQC 7.1-2-4, Field Quality Control Procedure
Amperage
Verification, dated
November 7, 1978.
The inspector
reviewed
numerous receipt inspection reports
and certified
material test reports for electrodes
and filler wire.
The rod and wire
met the requirements
of Section III, NB-2400 of the
ASME Boiler and
Pressure
Vessel
Code, including the,.charpy
impact test results for carbon
steel
and the residual
chemical
elements
which are required to be
reported.
Portable
rod ovens
and stationary
ovens
had
been calibrated
every three months
and each welder had
been
checked
once
a week for
amperage verification by using
a calibrated
tong tester .
The inspector
reviewed
numerous material requisitions
and weld data reports
and
verified that the correct welding material
was used.
An inspection
was
made of welding material
issue stations
and the
inspector
observed that low hydrogen electrodes
(E7018), which were
out of their original containers,
were stored in ovens within the
temperature
parameters
of 300oF + 50
.
Marking on E7018 containers
included heat
number
and lot number,
and all rod, wire, and consumable
inserts
were fully traceable
to material certifications
and purchase
orders.
The inspector learned that each welder is assigned
a portable
rod oven
and rod stub container,
which are returned at the end of each
shift.
During tours of the plant, the inspector noticed that portable
rod ovens were plugged in and rod stubs
were controlled.
Monthly audits,
done
by ITT Grinnell Quality Control personnel
were reviewed
and the
audits included surveillances of housekeeping,
rod stubs
on floor,
portable rod ovens,
and stationary rod ovens.

Control of Com onents
An inspection
was
made of the .Stone
5 Webster storage
area for ASME
Boiler and Pressure
Vessel
Code classified material.
It was discovered
that Stone
5 Webster
had not established
a storage control
system for
ASME Code Class material,
so as to distinguish Class
1 from Class
2 and
Class
3 or to distinguish Class
2 from Class
3.
A control
system is
necessary
to prevent using
a restricted
Code Class
item in another
Code
Class application..
Fortunately, only Class
2 material
had
been received
on site, but future shipments will include 'Class
1 items.
An example of
the difference in ASME Code Classes
is apparent
in seamless fittings.
ASME Boiler and Pressure
Vessel
Code,
Class
1 seamless fittings, purchased
to NB-2550 require nondestructive
examinations while Class
2 seamless
fittings purchased
to NC-2550 do not require nondestructive
examinations.
A manufacturer
may furnish Class
1 and Class
2 fittings to the site with
the
same
though only the Class
1 fittings will be
nondestructively
examined.
Similar differences
in Code Class requirements
exist for plates,
flanges, nuts, bolts,
and pipe.
Stone
5 Webster
recognized
the need for Code Class control
and is in the process of
establishing
an identification and segregation
system to preclude
a
possible
misuse of material.
This item will remain open
and the inspector
plans to followup this concern in a future inspection period.
(410/81-14-02)
While reviewing ITT Grinnell weld data reports,
the inspector discovered
that ITT Grinnell welding inspectors
record the heat
numbers of welding
material
used
on the weld data report, but do not 'verify the
acceptability of the heat
numbers for that specific application.
Fortunately, all welding material is purchased
to
ASME Boiler and
Pressure
Vessel
Code,
Section III, NB-2400, Class
1, but the possibility
exists for the usage of the wrong type of Class
1 rod or wire.
During
discussions
of the potential
problems with Grinnell, the g.
C. Manager
stated
he would consider
the issuance of traceability documents, listing
acceptable
heat
numbers of material specifications,
to the g.
C. welding
inspectors
for welding material
and loose piping components (fittings,
flanges, etc., that do not have
an
"NPT" identification stamp).
This
measure
would ensure
acceptable
material
usage for specific design
applications.
The inspector requested
the licensee to address
the
following concerns:
(1)
Adequacy of ITT Grinnell g. A. Program concerning verification of
welding material
used,
as recorded
on the weld data
report~ by heat
number.
(2)
Adequacy of ITT Grinnell g. A. Program concerning verification of
non
"NPT" stamped
piping components
welded to spool pieces
in the
field, as recorded
on the weld data report,
both for heat
numbers
and wall thicknesses.
This item will remain unresolved
pending licensee
response
to the above
two items and possible corrective action by ITT Grinnell.

The inspector witnessed fit-up and welding in progress
on Fuel
Pool
Columns
B4, B7, B13,
and
B16 at elevation 266'f the secondary-containment;
Drawing
E-519, welding detail prequalified joint BU4A and weld data records
were
examined,
while welder knowledge of preheat
and weld size requirements
was
verified in discussions
with the inspector.
g. A. inspection of in-process
and final weld criteria were noted
and construction controls over the
welding sequence,
care of the base metals,
and knowledge of the proper
quality criteria were evident.
While inspecting the fit-up on Fuel
Pool
Column B7, the inspector
observed
there
was
a gap between the backing bar
and the
base metal, which exceeded
the allowable spacing.
On
a subsequent
inspection,
the inspector noticed that the gap
had
been
reduced
by shims
and
was within the allowable tolerance
as required
by Engineering
and Design
Change
Request,
V19892.
In addition, the inspector
examined the following structural
