Docket No. 50-400
License
No. NPF-63
During an
NRC inspection
conducted
on February
5 - March 4,
1995,
a violation
of NRC requirements
was identified.
In accordance
with the "General
Statement
of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2,
Appendix C, the violation is listed below:
TS 6.8. l.a requires
procedures
recommended
in Appendix A of Regulatory
Guide 1.33,
Rev.
2, February
1978,
be established,
implemented,
and
maintained.
Regulatory
Guide 1.33 section 8.b.(1).(l) includes
~
procedures
for .reactor protection
system surveillance tests,
inspections
and calibrations.
Regulatory
Guide 1.33 section
9.a includes
procedures
appropriate for the circumstances
for performing maintenance
that can
affect the performance of safety-related
equipment.
These requirements
were further implemented
by Corrective Maintenance
Procedure
CM-I0113,
Revision 1/2 "Calibration Check
and Adjustment of Westinghouse
SSPC
[Solid State Protection Cabinet]
Power Supplies."
This procedure
stated
that it contained all the information needed for the bench calibration
check
and adjustment of certain Westinghouse
power supplies
and that it
may be used for receipt testing, testing following rework,
and also
adjustment
and troubleshooting
when
an instrument malfunction was
suspected.
These
power supplies
served
the solid state protection
system which included engineered
safety feature
and reactor protection
logic and output circuitry.
Contrary to the above,
on February
10,
1995, the licensee
had failed to
adequately
establish
and maintain procedure
CM-I0113,
Rev. 1/2,
such
that the procedure
was inadequate
to accomplish the functions stated
in
the procedure.
While the procedure
checked
and adjusted
the overvoltage
protection,
no-load output voltage,
and current limit protection, it
neither specified
acceptance
criteria nor recorded
equipment
performance
for important operational
attributes
such
as output voltage regulation,
response
to input voltage variation,
and
AC ripple.
The procedure
was
being used to bench check spare
power supplies
in anticipation of need
during
a planned on-line modification to the Solid State Protection
System.
This is a Severity Level
IV violation (Supplement I).
Pursuant to the provisions of 10 CFR 2.201, Carolina
Power
and Light Company
is hereby required to submit
a written statement
or explanation to the
U. S.
Nuclear Regulatory
Commission,
ATTN:

violation, or, if contested,
the basis for disputing the violation, (2) the
corrective steps that have

t
corrective steps that will be taken to avoid further violations,
and
(4) the

date
when full compliance will be achieved.
Your response
may reference
or
include'previous
docketed
correspondence, if the correspondence
adequately
addresses
the required response.
If an adequate
reply is not received within
the time specified in this Notice,
an order or Demand for Information may be
issued
as to why the license
should not be modified, suspended,
or revoked,
or
why such other action
as
may be proper should not be taken.
Where good cause
is shown, consideration will be given to extending the response
time.
