Docket No.:
50-298
I
Cooper Nuclear Station
License No.: DPR 46
During an NRC inspection conducted from November 15 through December 26,1998, two
violations of NRC requirements were identified. In accordance with the " General Statement of
Policy and Procedure for NRC Enforcement Actions," NUREG-1600, the violations are listed
below:
A.
Technical Specification 5.4.1 requires, in part, that written procedures be established,
implemented, and maintained that meet the applicable procedures recommended in
Appendix A of NRC Regulatory Guide 1.33. Appendix A of NRC Regulatory Guide 1.33
requires procedures for log entries, equipment control (tagging), replacement and repair
of recirculation pump seals, and a plant fire protection program.
Contrary to the above,
1.
On December 2,1998, NRC inspectors identified that operators did not
implement the Procedure 2.0.2, " Operations Logs and Reports," Revision 44,
Step 8.8, requirement that the shift supervisor record inoperable Technical
Specification equipment in the Technical Specifications tracking form. As a
result, the operators authorized maintenance on the reactor equipment cooling
system without recognizing or recording that the maintenance would render the
Residual Heat Removal Loop A pumps inoperable.
2.
On December 5, NRC inspectors identified that operators did not implement the
Procedure 0.9, " Tagging Orders," Revision 22C3, Step 5.1, requirement to hang
and remove tags in a specified order. As a result, operators did not hang tags
for Valves CS-172, CS-173, and CS-V-14A in the correct order, resulting in the
unintentional draining of approximately 1.4 inches of water from the reactor.
3.
On December 13, NRC licensee identified that technicians did not implement
Step 8.2.38 or correctly implement Step 8.2.39 of Procedure 7.2.5.1, " Reactor
Recirculation Pump Seal Cartridge Removal and Installation," Revision 13. As a
result, they incorrectly installed the thrust collar of the Reactor Recirculation
,
Pump B seat. The seal subsequently failed.
4.
On December 2, NRC inspectors identified that a fire watch failed to implement
the Procedure 0.39, " Fire Watches," Revision 18, Step 8.14, requirement that
combustible materials and openings in walls and floors within 35-foot radius of
hot water be protected / covered with noncombustible blankets. Inspectors found
l
unprotected combustible material and an opening in the floor within a 35-foot
'
radius of the hot work area.
This is a Severity Level IV violation (Supplement 1) (50-298/98008-01).

B.
10 CFR Part 50, Appendix B, Criterion XVI, requires, in part, that measures shall be
established to assure that conditions adverse to quality, such as failures, malfunctions,
deficiencies, deviations, defective material and equipment, and nonconformances are
promptly identified and corrected. In the case of significant conditions adverse to
quality, the measures shall assure that the cause of the condition is determined and that
corrective actions will be taken to preclude repetition.
Contrary to the above, the licensee failed to take effective measures to preclude
repetition of inadvertent opening of the torus-to-drywell vacuum breaker documented in
Licensee Event Report 50-298/97-007, " Opening of a torus-to-drywell vacuum breaker."
Specifically, the licensee failed to take reasonable action to prevent inadvertent opening
of the vacuum breaker for all conditions that could reasonably be expected, as
documented in procedures and design documents.
This is a Severity Level IV violation (Supplement 1) (50-298/98008-02).
Pursuant to the provisions of 10 CFR 2.201, Nebraska Public Power District is hereby required
to submit a written statement or explanation to the U.S. Nuclear Regulatory Commission,
ATTN: Document Control Desk, Washington, D.C. 20555, with a copy to the Regional
Administrator, Region IV,611 Ryan Plaza Drive, Suite 400, Arlington, Texas 76011, and a copy
to the NRC Resident inspector at the facility that is the subject of this Notice, within 30 days of
the date of the letter transmitting this Notice of Violation (Notice). This reply should be clearly
marked as a " Reply to a Notice of Violation" and should include for each violation: (1) the
reason for the violation, or, if contested, the basis for disputing the violation or severity level,
1
(2) the corrective steps that have been taken and the results achieved, (3) the 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 a 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.
If you contest this enforcement action, you should also provide a copy of your response to the
Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington,
DC 20555-0001.
Your response will be placed in the NRC Public Document Room (PDR). Therefore, to the
extent possible, the response should not include any personal privacy, proprietary, or
safeguards information so that it can be placed in the PDR without redaction. If personal
privacy or proprietary information is necessary to provide an acceptable response, then please
provide a bracketed copy of your response that identifies the information that should be
protected and a redacted copy of your response that deletes such information. If you request
withholding of such material, you must specifically identify the portions of your response that
you seek to have withheld and provide in detail the bases for your claim of withholding (e.g.,
explain why the disclosure of information will create an unwarranted invasion of personal
privacy or provide the information required by 10 CFR 2.790(b) to support a request for
..
.
.
3-
withholding confidential commercial or financial information).' If safeguards information is
necessary to provide an acceptable response, please provide the level of protection described
in 10 CFR 73.21.
In accordance with 10 CFR 19.11, you may be required to post this Notice within two working
days.
