RESPONSE TO NOTICE OF VIOLATION 50-458/8627-01
LEVEL IV
REFERENCE
Notice of Violation - J. E.
Gagliardo letter to W. J. Cahill, Jr.
dated October 24, 1986
FAILURE TO MEET ELECTRICAL SPECIFICATION REQUIREMENTS
REASON FOR THE VIOLATION
During
a
Battery
System
Walkdown, it was noted by the Nuclear
Regulatory Commission (NRC) Senior Resident Inspector (SRI)
that
the
positive
to
the
Division
III
Batteries contained
splices
which were
not
made
in
a
pull
box.
This
is
a
nonconformance
to Stone & Webster Engineering Corporation (SWEC)
Electrical Specification 248.000.
In addition, the SRI expressed
concerns about the cable training and support.
These
splices
were
made
by the construction forces during the
implementation of a design change initiated
by
Engineering
and
Design
Coordination
Report
(E&DCR) P22099.
This design change
required cable, 1CSHNOK601, a three (3) conductor number two (#2)
cable,
b-
terminated with all three conductors to the positive
battery I
and a new cable, 1CSHNOK608,
be
installed
to
the
negative battery post.
The previous design was for 1CSHNOK601 to
be terminated at the battery, 1E22*S001 BAT, with one conductor at
the
positive
post,
one
conductor at the negative post and one
conductor spared.
The design change did not specify a splice
to
be
made
at the battery.
The installation Specification 248.000
allows splicing of cable as long as the splices are
in
junction
boxes,
pull
boxes,
in
conduit fittings in conduit with single
circuits or within equipment enclosures.
There
were
no
nonconformances
identified
during
this
modification, therefore, it is presumed that one of the following
occurred:
1)
The
construction
forces
interpreted
the
specification
requirements'to consider the battery room as an enclosure for
the batteries
(i.e., an equipment enclosure), or
2)
The
construction
forces
overlooked
the
restrictions
for
making splices in this case.
The
Quality
Control
inspector
for
this
installation and the
craftsman are no longer employed at River
Bend
Station.
GSU's
conclusion
upon
investigating
this
condition is that the root
cause is indeterminate.

CORRECTIVE STEPS WHICH HAVE BEEN TAKEN AND THE RESULTS ACHIEVED
Condition
Report
(CR)
86-1383
was
initiated
to
provide
investigation
and
corrective
action for this problem.
Stone &
Webster Engineering's evaluation has shown that the Division
III
Battery
cable
splice
was not in conformance with Specification
248.000.
The splice will be
enclosed
in
accordance
with
the
intent
of
Electrical
Specificaticn
248.000
via
Modification
Request (MR) 86-1752.
This MR also addresses cable training
and
supports.
Further
inspections
were
performed
by
the Design
System Engineer on Divisions I and II battery connections and
no
similar nonconformances to Specification 248.000 were found.
An
independent
review
and
reinspection of the Quality Control
Inspector's
work was
previously
performed
by
GSU
Quality
Assurance
(QA)
Department
in
September,
1985.
This
review
revealed
no
problems
with
the
inspector's
performance.
An
informal
walkdown
of
selected
electrical equipment enclosures
conducted during October and November, 1985 by GSU QA
Department
did
not
identify
any
similar
Electrical
Specification
nonconformances.
The GSU QA Department coordinated an additional
walkdown
of
areas
that
contain safety-related power cables in
free air.
No additional
cable
splice
violations
were
found.
j
Based
on
the above mentioned reviews and walkdowns, it has been
concluded that the subject of concern is an isolated case.
CORRECTIVE STEPS WHICH WILL BE TAKEN TO AVOID FURTHER VIOLATIONS
No further corrective action is necessary.
DATE WHEN FULL COMPLIANCE WILL BE ACHIEVED
With the closure of CR
86-1383
and
the
implementation
of
86-1752,
full
compliance
will
be
achieved
during
the first
quarter of 1987.

RESPONSE TO NOTICE OF VIOLATION 50-458/8627-02
'
LEVEL IV
REFERENCE
Notice of Violation - J. E.
Gagliardo letter to W. J. Cahill, Jr.
dated October 24, 1986.
FAILURE TO FOLLOW A SURVEILLANCE TEST PACKAGE
REASON FOR THE VIOLATION
When
performing
Surveillance
Test
Procedure
(STP)-203-1102,
" Battery
Weekly
Surveillance
Test
for
1E22*S001 BAT",
the
procedure
requires the technician to obtain and record the pilot
cell numbers using
the
previous
performance
of
STP-203-1320,
"1E22*S001 BAT
Quarterly Surveillance Test".
The pilot cells are
defined as the cells having the lowest specific gravities.
When
obtaining the pilot cell numbers following the performance of the
quarterly
test
on
August
12,
1986,
maintenance
personnel
inadvertently recorded the cell number having the lowest specific
gravity (cell #37) and the cell with the
third
lowest
specific
gravity
(cell
- 52).
This
personnel
oversight
resulted in a
deviation of the procedural requirements of STP-203-1102.
CORRECTIVE STEPS WHICH HAVE BEEN TAKEN AND THE RESULTS ACHIEVED
Immediately
upon
discovering
the
error
of
identifying
the
incorrect
pilot
cell
number, a conservative approach was taken
and the batteries were removed from
service.
STP-203-1102
was
rerun on September 12, 1986 with satisfactory results.
Following
the performance of STP-203-1102 on September 12, 1986,
the data recorded by the procedure since the last performance
of
STP-203-1320
(Quarterly Test), was reviewed to ensure compliance
with River Bend Technical Specifications and IEEE 450-1975.
The
review
concluded
that
the data recorded met the intent of IEEE 450-1975 and was within the limits
specified
by
the
Technical
Specifications.
While
performing
the history review of the data recorded during
the
performances
of
STP-203-1102,
it
was
discovered
that
STP-203-1102 performed on August 18, 1986 also failed to identify
the correct pilot cell numbers.
This was caused by personnel not
having
available
the
latest
performance
of
STP-203-1302
(Quarterly Test) when obtaining the pilot cell numbers.
CORRECTIVE STEPS WHICH WILL BE TAKEN TO AVOID FURTHER VIOLATIONS
Temporary Change Notices (TCNs)
06-1416,
86-1417,
86-1418
and
86-1419
have
been
issued
against
procedures
STP-305-1100,
. . .
,
.
ATTACHMENT 2 (cont'd.)
.
STP-305-1101, STP-203-1102 and PMP-1036 respectively
to
require
independent
verification
for
ensuring
that the cells with the
lowest specific gravities are used as pilot cells.
To ensure the latest Quarterly Battery
Test
is
available
when
obtaining
pilot
cell
numbers,
the
Electrical
Maintenance
Supervisor will maintain the latest
Quarterly
Battery
Test
on
file
until the next performance of the test.
Upon completion of
the next scheduled quarterly battery
test
the
results
of
the
Previous
quarterly
test
will
be
transmitted to the Permanent
Plant Filo (PPF).
DATE FULL COMPLIANCE WILL BE ACHIEVED
The affected procedures have been revised.
