Findings
a.
Violation
(Closed) Violation 50-260/89-57-01,
Pipe Support Discrepancies
This violation involved
discrepancies
found
during
two previous
inspections
of the support modification program. All items in the
violation and the
commitments
in the response
to the violation from
the licensee
had
been
reviewed
and closed
in Inspection
Report
Nos.
Cl,,
90-09
and 90-19 except
commitments
item 3.
This was
a commitment for
the
licensee's
Modification group
and
gC
department
to
perform
walkdowns of in-process
Engineering
Change
Notes
(ECNs)
and
Design
Change Notices
(DCNs) to ensure that there were
no further examples of
the conditions 'identified in the
NRC violation.
This effort was to be
performed
in parallel
with the
79-02/79-14
modification effort.
However,
the licensee's
internal
memorandum
R28
900306
901,
dated
March 7,
1990, deviated
from the above
commitment in that
gC would not
be required
to participate
in the effort. In response
to the
NRC
concerns
regarding
this
change,
the
licensee
issued
internal
memorandum
R80 900412
967,
dated
April 12,
1990,
to fulfill the
commitment.
The
memorandum
with the
attached
action
plan
and
checklist stated that:
1) Effective April 16,1990,
the Modification team composed
of a
responsible
engineer
and
a craft supervisor, will be assigned
to
perform the final walkdown for all completed
work plans;
2)
gC department will perform an independent
walkdown on
a randomly
selected
samples of completed final walkdowns performed
by the
Modification team;
and
3)
A 10 percent
sample of 79-02/79-14
work plans that were
completed
before April 16,
1990, will be jointly walked
down by
gC and Modifications.
The
inspectors
discussed
the violation
and
commitment
with the
licensee's
engineers
and
reviewed
the
information provided.
The
licensee's
gC
and
Modification
team
walked
down
10
percent
of
approximately
580 pipe supports
whose work plans
were completed before
April 16,
1990.
The Modification team
walked
down
100 percent of
about
1000 pipe supports
independently
or jointly with gC for the work
plans
completed after April 16,
1990.
gC performed
a walkdown of
about
200 supports
independently
or jointly with the Modification team
whose
work
plans
were
completed
after April
16,
1990.
The
Modification team
and
gC did not find
a major discrepancy,
but did
find 11 minor discrepancies
such
as dimension differences for support
locations, differences
between
the Bill of Materials
and
as installed,
component
configurations
and part
numbers
not matched,
old parts
not
removed,
settings
out of range,
loose
lock nuts,
rust in
components,
etc.
Based
on the licensee's
effort, progress,
and the
continuing commitment,
the violation is considered
closed.
Inspector
Followup Items
(Closed)
Item 50-259,260,296/87-33-04:
"Deficient Welds
In
Piping Discovered
During MIC Inspection"
This item was discovered
during
a review of activities related to the
Browns Ferry Microbiologically Induced
Corrosion
(MIC) Program.
As
the
result
of this
review
three
concerns
were identified
and
subsequently
documented
in NRC Report
No. 50-259,260,296/87-33-04,
one
of
which
was
discussed
and
closed
in
NRC
Report
No.
50-259,260,296/89-20.
Of the
two remaining
concerns,
the
one relating to weld defects,
is
addressed
in NRC Report
No. 50-259,260,296/88-35,
which indicated that
the resident
inspectors
had reviewed,
and
found acceptable
for fuel
load,
the licensee's
actions
relating to this concern.
It remained
open
pending
a
scheduled
review,
by
NRC staff
Nondestructive
Examination
(NDE) personnel,
of 95 Emergency
Essential
Cooling Water
(EECW)
piping
radiographs.
This
review
was
completed
on
Oecember
23,
1988,
and
documented
in
NRC Office of Nuclear Reactor
Regulations
(NRR) Letter dated
March
1989 which closed this portion of
this followup item
.
The
remaining
concern
related
to the
adequacy
of the licensee's
proposed
program,
as discussed
in
NRC Report 50-259,260,296/89-20.
On
~October
24,
1989,
NRR issued
Supplement
1 to the Safety
Evaluation
Report
(SER)
on
The
Browns
Ferry Nuclear
Performance
Plan,
which
concludes,
in paragraph
3. 14,
that
the
licensee's
inspection
and
monitoring
program for MIC will provide
reasonable
assurance
that
those
systems will not lose their capability to perform their safety
functions
due
to
MIC damage.
A11
the
concerns
being
adequately
addressed
this matter is considered
closed.
(Open)
Item 50-260/89-16-09:
"System
Flow Loss
Oue to Corrosion of
Carbon Steel
Piping"
This item concerned
the licensee's
method for calculation of pressure
drop in carbon
steel
piping
and
the fact that the
method
did not
account
for
an
increase
in relative
roughness
of pipe internal
surfaces
as
the piping ages
(due to corrosion or other causes).
The
specific concern
was related to the Core Spray
(CS) system.
The licensee
indicated that the
CS system at
BFN contains
condensate
grade water
and is not susceptible
to internal corrosion other than
a
smooth
iron oxide film.
This film is not
a factor which would
adversely
affect
pressure
loss.
The licensee
concluded
that
the
methodology in the pressure
drop calculations
was appropriate.
Because
the
licensee
did
not
provide
any
basis
to support
the
statement
that
the
condensate
grade
water
would not affect
the
internal
roughness
of carbon steel
piping, This matter remains
open.

Reportable
Occurrences
(92700)
The Licensee
Event Reports
(LERs) listed below were reviewed to determine
if the
information provided
met
NRC requirements.
The determinations
included
the verification of compliance with TS
and regulatory require-
ments,
and addressed
the adequacy
of the event description,
the corrective
actions taken,
the existence of potential
generic problems,
compliance with
reporting requirements,
and the relative safety significance of each event.
Additional in-plant
reviews
and
discussions
with plant personnel,
as
appropriate,
were co'nducted.
(Closed)
LER 50-259/89-01:
"Oesign Oversight
on Seismic gualification of
4160 Volt and 480 Volt Breakers
Places
the Plant in Unanalyzed Condition"
On January
18,1989,
the licensee
determined
that seismic
documentation
could not be established
for various positions of 4160 and 480 volt safety
related circuit breakers.
This determination
resulted
in the plant being
in an unanalyzed
condition.
The licensee
put the affected
breakers
in an
analyzed
position or
removed
them
frorg the vicinity of safety
related
equipment.
In addition the licensee
committed to provide administrative
controls
by
March
8,
1989
to ensure
breaker
seismic qualification is
maintained.
(Closed)
LER 50-260/89-16:
"Technical
Specification Violation Due to
a
Seismic Unqualified 480 Volt Shutdown Board"
On May 30,
1989, the licensee
determined that the 480 volt Shutdown
Board
2A.
had not
been
maintained
in
a seismically qualified configuration in that
the normal feeder breaker for the board
was in the disconnect
position with
the breaker
compartment
door open.
This placed the Core Spray Loop
1 in an
inoperable condition.
The core spray loop was required to comply with the
technical
specifications.
This
event
resulted
from
an "unidentified
person" failing to comply with the administrative controls instituted
as
the result of LER 50-259/89-01
discussed
above.
The inspectors
performed
a walkdown inspection of 33 safety-related
panels
containing
approximately
1500
breakers
to evaluate
compliance
with the
administrative controls instituted
as the result of LER 50-259/89-01.
In
'ddition,
the inspectors
reviewed the package
submitted
by the licensee for
the closure of both
LERs discussed
above.
The results of these
inspections
are discussed
below.
The inspectors
noted three
panel
doors
open including one
on
a breaker, all
of which are violations of the above discussed
administrative controls.
It
should
be
noted that,
because
all three units
are defueled, all seismic
controls
have
been
suspended,
and the percentage
of noncompliance with the
administrative controls is very small, there is
no safety significance to
this matter.
The inspectors
noted that, in the LERs, there
was
no mention of training to
assure
understanding,
and
compliance
with the instituted administrative
controls.
Additional
investigation
indicated
that training
had
been
performed
though
not
discussed.
The
inspectors
determined
that
the
licensee's
corrective actions
have
been
adequate
to prevent recurrence
of
this event.
Both the above
items are considered
closed.

b.
Walkdown Re-Inspection
The
inspectors
randomly
selected
33
pipe
supports
which
had
previously
been
inspected
and
accepted
by
the
licensee
construction
foreman
and
gC inspectors.
The
33 pipe supports
were all in large bore piping for three different safety-related
systems
located
both inside
and
outside
of containment.
The
walkdown
re-inspection
was
completed
with assistance
from
licensee's
engineers
and
a
gC mechanical
inspector
who was also
qualified
as
a welding inspector.
The supports
were partially
re-inspected
against
detail
drawings,
including the original
walkdown sketches,
the
Design
Change
Notices
(DCNs),
and
the
Field

The licensee's
engineer
and
QC inspector reinspected
the situation
and established
a I/32
inch clearance
by manually rotating the snubber.
However, after
a further investigation, it was found that the recirculation
pump
movement
during the operation will cause
the hydraulic snubber
to bind.
The licensee
agreed
to perform further evaluation
to
determine
any possible
clearance
problems for this support
and
other supports
on the recirculation
pumps
and will have observa-
tions for clearances
on all supports
on the recirculation
pumps
during hot function test.
This item is identified as Inspector

Pipe Weld
Contrary to
ASME Code Section
IX Paragraph
IW-200.2 (c), which
states
in part
"The
PgR shall list actual
variables
used within
the limits of a narrow range rather
than the full range of the
variables
allowed. ...,"
PgR GT-SNll-0-3-C lists wide ranges for
shielding
gas flow, welding current
and arc voltage.
This is of
concern
because
the minimum value for the nonessential
variable
gW-408.3
"A decrease
of 10Ã or more in the flow rate of shielding
gas..."
and
the
maximum value for the nonessential
variable
gW-409. 1 "...an
increase
in heat input..." cannot
be properly
determined for specification in the
WPS.
Contrary to ASME Code Section
IX paragraph
gW-403.6, which states
"...For
thickness of 5/8 in.
and greater
the minimum thickness
qualified is 5/8 in.," PgR GT-SN11-0-3-C,
an impact tested
P(R,
stated
the test
plate
thickness
was
1-7/8"
and
the
minimum,
thickness
qualified
was
3/16".
In addition
there
is
no
referenced
PgR that would support welding with WPS GT-SNll-0-03B
on
base
material
thickness
less
than
0.432"
even
though
TYA
General
Construction Specification
G-29 permits welding with WPS
GT-SM11-0-03B on material
thickness
as thin as 0. 187".
The
above
are
examples
of lack of adequate
control of the welding
process
at
the
Browns
Ferry site,
in that it appears
that
PgR GT-SN11-0-3-C
does
not appropriately
support welding for impact
test required applications.
Failure to control welding is
a violation
of
10 CFR 50, Appendix B, Criterion IX, which requires
adequate
measures
be
established
to control
special
processes,
including
welding,
to
assure
accomplishment
of those
special
processes
in
accordance
with applicable
codes
and standards.
This violation will
be identified as 50-259,260,296/90-26-02:
"Failure to Control Welding
for Impact Test Required Applications."

In addition to the violation noted
above,
the inspectors
identified the
following items of lesser safety significance.
The inspectors
noted
on the
Weld Data
Sheet for weld EECW-3-002-001
the following:
'he
welder
foreman
erroneously
documented
the
Weld Procedure
Number
as
GT-SMll-B3 vice GT-SMll-0-3B, in several
locations
.
The
gC inspector
who
made
the fitup inspection
made
the
same
error.
Although the welding
had
progressed
past
the fitup stage,
the
space for the Authorized Nuclear Inservice Inspector's
(ANII's)
hold point had not been
signed off.
The inspectors
were informed
that the ANII had
indeed
signed off for the fitup in a separate
location
in the
package.
The
reason
gi.ven for the
remote
sign-off was
due to a dispute over the number of places
the ANIIs
are required sign-off in each
package.
The licensee
has
no formal
documented
program for the maintenance
of
welding equipment with the exception of BF 14.28,
dated
10/17/83,
"
CONTROL
OF
PORTABLE ELECTRICAL CORDS
AND DEVICES" which should
cover
welding cables.
The licensee
had
a
program for welding equipment
maintenance
described
in procedure
MAI -12,
but that procedure
was
discontinued
in 1987.
This is of concern,
in view of the non-isolable
leak in control
rod drive tubing, which was
caused
by an arc from a
degraded
welding cable, that occurred
August 8,
1990.
No
violations
or
deviations
were
identified
except
as
noted
in
paragraph
5.e.
6.
Exit Interview
The inspection
scope
and results
were summarized
on August 10,
1990, with
those
persons
indicated in paragraph
1.
The inspectors
described
the areas
inspected
and discussed
in detail the inspection results listed below.
The
item concerning
welding
was identified as
an unresolved
item at the exit
interview.
The licensee
was
informed by telephone
on August 15,
1990 that the welding
item would
be cited
as
a violation.
Proprietary
information is not
contained
in this report.
Dissenting
comments
were not received
from the
licensee.
