REPLY TO NOTICE OF VIOLATION
Inspection No. 50-334/88-21
Letter dated August 3, 1988
VIOLATION (Severity Level IV, Supplement I)
Description of Violation (88-21-01)
requires
that
qualification
of each component be
based
on
testing
or
experience
with
identical
equipment or with
similar
equipment
with
a
supporting
analysis
to
show
that
the
equipment to be qualified is acceptable.
.
Beaver
Valley
site
administrative
procedure Chapter 31, Revision 2
Section
2a
requires
that equipment have sufficient documentation to
establish that the equipment is environmentally qualified.
Contrary
to
the
above
on May 12, 1988, the equipment qualification
file
0044
Revision
3
for
motor operated valve MOV-SI-885B did not
have
sufficient documentation to estcblish the qualification of Ideal
Model wirenuts utilized in the motor stator wiring circuit.
.
Admission or Denial of Alleged Violation
The violation is correct as stated.
Reason for Violation
,
During
the
performance
of
a
routine
Equipment Qualification (EQ)
inspection
in
April,
1987
for
motor operated valve MOV-SI-885B, a
motor lead wire was found damaged and had to be repaired.
The
maintenance
instructions / procedures
used
for the EQ inspection
did
not
specifically addreas the repair of the particular Limitorque
wiring
found
to be damaged since this wa; not part of the preplanned
inspection.
Consequently,
Maintenance obtained a wirenut which was
stocked
for use in safety related systems, but which was not approved
for
use
in
Electrical
Equipment
Qualification Master List (EEQML)
equipment.
Approved
methods
for
reconnecting / splicing
wiring in
EEQML
equipment
were
in existence at that time and should have been
used.
DLC
believes
the major contributing factor to the occurrence of this
violation
was
a
weakness on the part of the Maintenance and Quality
Control
personnel
involved
in understanding a certain aspect of the
program.
Namely,
the
introduction
of
any
new
or different
materials
into
equipment
on
the
EEQML
requires
specific
prior
approval by the Equipment Qualification Group.
Corrective Steps Which Have Been Taken And Results Achieved
j
The
wire
nut
for
valve
MOV-SI-885B
was replaced with a qualified
compression
crimp
connector
on
May
12,
1988 via Maintenance Work
'
Request 883020.

AEPLY.TO NOTICE OF VIOLATION
Pags 2
-
m
To. a'scertain
if
the
possibility
existed of wirenuts being used in
other
MOVs,
a
search of Maintenance Work Requests that may have
involved
wiring
changes to MOVs was performed.
We also inspected an
additional
43
operators
including
21
equipped
with
dual voltage
motors
for
the
presence
of
splice
connectors
other
than
T&B
compression
crimp connectors.
As a result of these efforts one other
wirenut
installation was found in MOV-SI-864A.
This wirenut was also
replaced with
a
qualified
crimp
connector
on
May
13,
1988 via
Maintenance Work Request 883011.
Station
procurement has removed wire nuts from stock for applications
in
safety
related
systems to preclude future misapplication of them
,
in equipment on the Electrical Equipment Qualification Manter List.
Maintenance
supervisors have been instructed to perform a timely post "
maintenance
revicw
of
EQ maintenance work requests prior to turning
the
equipment
over
to
operations
to assure the equipment aas been
properly
repaired
and
restored.
A
repeat
training review of EQ
maintenance
requirements
was
conducted
for
Electrical Maintenance
personnel
on
August
16
and
September 1, 1988, emphasizing that to
preserve
environmental
qualification,
particular
attention must be
made
not to introduce unqualified materials into the equipment or its
interfaces
which
have
been
qualified.
An
8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> EQ seminar.for
Quality
Control inspectors and supervisors and Electrical Maintenance
and
Construction
supervisors
was
given
on August 17 and 18, 1988.
This
additional
training
has resulted in a better understanding and
heightened
awareness
of the combined effort required by Maintenance,
Quality
Control
and
Engineering
to
preserve
the
environmental
qualificatica of the equipment.
Corrective Steps Which Will Be Taken to Avoid Further Violations
A
review of Maintenance procedures is being conducted to identify any
special
requirements
for
qualified
spare
parts
to
preserve
the
qualification
of
the
Operators.
This
review will be
complated by September 30, 1988.
.
Additional
retraining
classes
will be held for those F,lectrical
'
Maintenance
personnel who have been unable to attend ther. classes to
date.
We anticipate this will be completed by September 20, 1988.
The Date When Full Compliance will be Achieved
Full
compliance
has
been
achieved.
As noted above, the review of
maintenance
procedures
and
retraining
should
be
completed
by
i
september 30, 1988.
