5.
Independent
Inspection Effort (Units
1 and 2)
a.
Construction Progress
The inspector
conducted
a
general
inspection
of the
Unit
3
and
4
auxiliary and reactor buildings and welding material
issue stations
to
observe
construction
progress
and construction
activities
such
as
welding, material handling and control, housekeeping
and storage.
b.
Storage
and Protection of Installed Equipment
With regard
to
the
inspection
of paragraph
S.a,
the
inspector
on
November 3-6,
1981,
accompanied
by
a representative.
of the licensee,
noted the following in the Units 3 and 4 reactor buildings:
(1)
Approximately
five
examples
of rigging
from or
supported
by installed safety related cable trays or piping.
(2)
Numerous examples of extraneous
markings and various
type's of tape
applied
to the surfaces
of safety related
components,
tanks
and
piping.
The inspector
discussed
the
above with the licensee
who stated
that
they had no documented
program to control the following:
Rigging from or scaffolding supported
by installed safety related
cable trays or piping.
The only existing control
on the above is
the "good judgement of t,he craft".
Surface
applied
substances
for safety
related
stainless
steel
applications to prevent deterioration.
The inspector informed the licensee that the
above indicated
inadequate
controls for storage
and preservation
of installed equipment.
Failure
to establish
controls for storage
and preservation
of equipment
in
accordance
with instructions
to prevent
damage,
is in violation of 10 CFR 50 Appendix B, Criterion XIII.
The above violation will be identi-
fied as
250,251/81-26-02:
"Failure to Establish Controls for Storage
and Preservation of Installed Equipment".
Within the areas
examined
no violations or deviations
were identified except
as described
in paragraph
S.b.

Repair (Units 3 and 4)
The
inspector
observed
welding
work activities 'for the
steam
generator
repair project as described
below to determine
whether applicable
code
and
procedure
requirements
were being met.
The governing overall
code for the
replacement
is the
ASME B&PV Code Section XI, 1977 Edition
with Addenda through the Summer
1978.
At the time of this inspection
the "A" generator
replacement
lower assembly,
the last of three,
had
been
moved into the unit three
containment.
The
inspector observed
a portion of the handling effort.
The inspector
observed
in-process
welding activities
as described
below to
determine whether applicable
code and procedure
requirements
were being met.
a.
Welding
The below listed welds
were
examined
in-process
to determine:
work
conducted
in
accordance
with traveler;
welder
identification
and
location;
welding
procedure;
WPS
assignment;
welding
technique
'and
sequence;
materials identity; weld geometry; fit-up; temporary attach-
ments;
gas purging; preheat; electrical characteristics;
shielding gas;
welding equipment condition; interpass
temperature;
interpass cleaning;
process
control
systems;
identity of welders; qualification of inspec-
tion personnel;
and weld history records.

b.
Welder (}ualifications
The inspector
reviewed the Chicago Bridge and Iron Company
(CB&I) and
Bechtel
Power Corporation
(BPC) programs for qualification of welders
and welding operators
for compliance with gA procedures
and
ASME Code
requirements.
(1)
The following welder qualification status
records
and "Records of

With regard
to
the
inspection
above,
the
inspector
noted
on
November
4,
1981, that the lead letter "B" was not attached to the
back of the film holders
for the
above test
assemblies
during
radiography.
The preceding
is contrary to
CB&I procedure
RT1,
Revision 4, "Radiographic Examination Procedure",
paragraph
5.5. 1,
which requires
the lead letter "B" to be placed
on the back of the
film holders during'radiography.
The above condition indicates
inadequate
measures
for the control
of special
processes
and is
an
example of violation 250,251/81-
26-01.
This matter is discussed further in paragraph 6.d(2).

Radiographs
of welder qualification test assemblies
for the below
listed welder were reviewed.

The above
WPS's
and their supporting
Procedure

(PgR's)
were
reviewed to ascertain
whether essential,
supplementary
and/or nonessential
variables
incluidng thermal
treatment
were
con-
sistent with code 'requirements;
whether the WPS's were properly quali-
fied and their supporting
P(}R's were accurate
and retrievable;
whether
all required
mechanical
tests
had
been
performed
and the results
met
the
minimum requirements;
whether
the
PgR's
had
been
reviewed
and
certified
by appropriate
personnel
and,
whether
any revi sions and/or
changes to nonessential
variables were noted.
With regard
to the
above,
the inspector
noted
on
November 4,
1981,
that for the
WPS's
above
and their supporting
PgR's,
the

ASME Code Section
IN were not
addressed
as required
by paragraph
gW-201. 1 of the
ASME Code
Section
IX, as indicated above.
Failure to include all pertinent information in the
WPS is in violation
of paragraph
(a)( 1) of 10 CFR 50.55a.
This violation will be identi-
fied as
250,251/81-26-03:
"Failure to Include All Required
Nonessen-
tial Variables in WPS".
d.
Welding Filler Material Control
The inspector
reviewed the, BPC and
CB&I programs for control of welding
materials to determine whether materials are being purchased,
accepted,
stored
and handled in accordance with gA procedures
and applicable
code
requirements.
The following specific areas
were examined:
Purchasing,
receiving,
storing,
distributing
and
handling
procedures,
material
identification;
and
inspection
of welding
material issuing stations.
Welding
material

With regard
to the inspection
above,
on
November 6,
1981,
the
inspector noted the Certified Material Test Reports
(CMTR) and the
Receiving Inspection
Reports
(RIR) for the materials
marked with a
star (*) where not retrievable.'he
licensee
indicated that they
0
would look further into the matter.
The inspector
stated that the
matter would
be identified
as
unresolved
item 250,251/81-26-04:
"Non-Retrievable CMTR's".
(2)
With regard
to the
inspection
above,
the
inspector
noted
on
November 4-5, 1981, the following conditions:
(a)
Type
E8018 welding electrodes
were
stored
in an unguarded,
unlocked
electrode
oven.
The
above
is contrary
to
Nuclear
equality
Manual
for
Section III Products,
.
Revision,
4
Construction,
Section
8
Welding,
paragraph
8.2.2. 1, which requires all welding materials
to be stored
in locked storage
areas or locked electrode
ovens.
(b)
Cold flux covered welding electrodes
were left for approxi-
mately
8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />
in
an
unenergized
protable
rod warmer.
The
above
is contrary
to
BPC Welding Standard,
WFMC-1 dated
April 15,
1981,
paragraph
4.5.6,
which requires portable
rod
warmers
to
be continuously
heated
or energized
during
use
except during transit time.
(c)
Type E7018 low hydrogen,
low alloy electrodes
were
used
from
an
open
bucket adjacent
to
an
energized
rod
warmer.
The
above
is contrary to
BPC Welding Standard
WFMC-1, paragraph
4.5.6 which requires
low hydrogen
low alloy electrodes
to be
used directly from portable rod warmers.
The
above
combined with the
examples
as discussed
in paragraph
6.b(3) indicates that the licensee
does
not have
adequate
measures
for
the
control
of special
processes.
Failure
to establish
adequate
measures
to control special
processes
including welding
is in violation of
Appendix B, Criterion IX.
This
violation will be identified
as
250,251/81-26-,01:
"Inadequate
Measures to Control Weldin
and Welder gualification".
g
Within the
areas
examined,
no violations
or deviations
were identified
except as described
in paragraph
numbers 6.b.(3), 6.c,
and 6.d(2).
