DUKE POWER COMPANY REPLY TO A NOTICE OF VIOLATION l
50-414/89-34 Technical Specification 6.8.1 requires that written procedures be established, implemented, and maintained coverin.g applicable activities recommended in Regulatory Guide 1.33, Revision 2. February 1978, included in these required procedures,-are the administrative procedures pertaining to the responsibilities for the proper removal and restoration of equipment and components.
Station Directive 3.1.1, Safety Tags and Delineation Tags, describes the procedures to be used for the issue, placement, recall, transformation t.nd removal of safety tags.
It is specifically required therein that the tag (s) 1 and tagout sheet entries be made out properly and accurately and be placed on the correct components / equipment.
Contrary to the above, on November 20, 1989, an inaccurate tagout record sheet and tag resulted in an operator opening the breaker on the 281 instead 1
of the 2B2 main feedwater turbine lube oil pump.
This caused the 2B main feedwater pump to trip which in turn initiated a main turbine runback.
1.
Admission or Denial of Vio'lation Duke Power Company admits to the violation of inadequate development and implementation of an equipment tagout.
2.
Reasons for Violation if Admitted The operator making the tagout looked up the wrong breaker in the electrical load list.
The supervisor that ordered the tagout failed to properly review the tagout.
The operator placing the tagout followed the instructions as written.
3.
Corrective Actions Taken and Results Achieved This incident has been discussed with the individuals involved in placing this tagout and the individual who created the tagout, thus veinforcing to these individuals the potential consequences of their improper actions.
4.
Corrective Actions to be Taken to Avoid Further Violations This incident was discussed at the shift supervisor's meeting on December 19, 1989 to ensure that all shifts are sensitive to the need to review tagouts for correctness during the implementation process.
l S.
Date of Full Compliance Duke Power Company is in full compliance.

PAGE 1 0F 2 DUKE POWER COMPANY reply TO A NOTICE OF VIOLATION 50-414/89-34 Technical Specification 6.8.1 requires that written procedures be established, implemented, and maintained covering applicable activities recommended in Regulatory Guide 1.33, Revision 2, February 1978.
Included in these required procedures, are the administrative procedures pertaining to the responsibilities for the proper removal and restoration of equipment and components.
Station Directive 3.1.1, Safety Tags and Delineation Tags, describes the procedures to be used for the issue, placement, recall, transformation and removal of safety tags.
It is specifically required therein that the tag (s) and tagout sheet entries be made out properly and accurately and be placed on the correct components / equipment.
Contrary to th? above, on November 20, 1989, the tagout associated with maintenance performed on waste gas valve IWG179 was inadequate in that the tagout excluded boundary valve IWG182. This led to an inadvertent radioactive gas release.
1.
Admission or Denial of Violation Duke Power Company admits the violation.
l 2.
Reasons for Violation if Admitted l
l This event was caused by a personnel error in that waste gas valve IWG182 was not identified as part of the isolations required i'cr the j
maintenance work to be performed. This rasulted in the portion of the I
system under maintenance not being completely isolated from the system.
3.
Corrective Actions Taken and Results Achieved a.
Chemistry Techniciar.s secured Unit I and 2 Volume Control Tank Purges and Geseous Waste Compressors, b.
Chemistry Technicians notified Operations of the Gauous Waste System pressure drop, i
c.
Chemistry and Radiation Protection personnel reviewed maintenance activities in progress and deterrined that gn was escaping from the valve stem leakoff header, d.
Chemistry Technicians isolated the valve stem leakoff hesder (IWG182).
e.
Radiation Protection personnel completed calculations to determine the quantity and Curie content of the release.

Corrective Actions to be Taken to Avoid Furcher Violations a.
OP/0/B/6500/26, Radwaste Chemistry Operating Procedure for Preparing and Isolating the Various Components of the Gaseous Waste System for Maintenance, will be revised to insure that valve stem leakoff headers are isolated when work is performed on applicable equipment.
b.
OP/0/B/6500/03, Radwaste Chemistry Operating Procedure for the Gaseous Waste (WG) System, will be changed to require notification of the Shift Manager in the event of any unusual incidents associated with WG System operation.
c.
PT/0/A/4200/03, Weekly inspection of Waste Gas System Leakage, will include notification requirements as described in Planned Item b.
d.
An Operator Aid Computer alarm will be established to alert Operators in the event of an upward trend as measured on EMF 41 (Auxiliary Building Ventilation Radiation Monitor).
L e.
OP/0/B/6500/26, Radwaste Chemistry Operating Procedure for
-Preparing and Isolating the Various Components of the Gaseous Waste System for Maintenance, will be evaluated to consider the
[
addition of specific, standard tagouts for Gaseous Waste valves.
L 5.
2 ate of ruilfompliance Jtems c. and d. of Section 4 have been completed.
The remaining items are in progress and will be completed by February 28, 1990.
