Catawha Nuclear Station Reply to a Notice of Violation 413, 414/91 13-01 Technical Specification 6.8.1 requires that written procedures be establishrd, implemented and maintained covering the activities referenced in Appendix A of Regulatory Guide 1.33, Revision 2 February 1978, including the operation and maintenance of plant sys' ems and components.
Contrary to the above:
A.
On hiay 5,1991, during fuel movement, the control room was contacted about conveying ice. Approval was given to co vey ice and draw air out of containment. The ice machine operator was unaware fuel movement had started. During the performance of this work, T/S 3.9.4 was violated due to drawing suction through penetration hi-371 during fuel movement.
B.
On April 20,1991, IRN 236 was discovered to be closed during D/G 1 A break-in run and testing.
C.
On hiay 10,1991, Unit 2 was in 3.0.3 for 13 minutes due to 2A and 2B Filter Exhaust Fans tagged at the same time for maintenance.
D.
On hiay 22, 1991, loss of boration flow path required by T/S 3/4.1.2 due to no emergency power to operable NV pump when making 1 A D/G inoperable for testing.
E.
On hiay 27,1991, load center ILXN was found de-energized.
RESPONSE
1.
- Brasons for Vitdallett.
A.
The ic:: machine operator did not use the Ice hiaking and Charging system procedure.
B.
The transferring of information from the Work Requests to the R&R sheet overlooked placing 1RN-236 on the R&R sheet.
C.
The operators inadvertently tagged a component in the operable train of Auxiliary Building Filtered Exhaust. This was a result of an inadequate review of the tagout.
D.
The SRO administratively removing the D/G from service failed to follow the initial conditions of the operating procedure.
1 y
Catawba Nuclear Station Reply to a Notice of Violation 413, 414/91 13 01 E.
The supervisor, determining restoration position for ILXN feeder breakers, failed to properly identify restoration position for load center.
2.
Corrective Actions Taken and the Results Achieved A.
The need to use procedure OP/0/ll/6200/16 in ice blowing activities has been emphasized to the Shift Supervisors of ice blowing crews.
B, --
- This is considered to be an isolated incident, of inattention to detail. This was evaluated by an Operation's committee and direct programmatic changes were not determined to be necessary, though some enhancements are being made to R&R forms and procedures. '
C.
The Shift Supervisor immediately dispatched an NLO to remove tags from VA fan motor ABFXF 211.
This event was discussed with personnel involved.
D.
This event was discussed in detail at the Shift Supervisor's Meeting July 8,1991.
The individual irivolved with the incident was counselled.
E.
An Operator update was issued to Operations personnel, it described the event and stated for future tagouts that breakers specified will be identified as being required to be closed or open..
3.
Corrective Actions to be Taken to Avoid Further Violatloris A.
The Ice Making and Charging System procedure will be revised to ensure that CROs and ice machine operators review existing unit conditions and their affects, prior to each initiation of ice blowing. The procedure will be revised to include -
acknowledgement by CROs of the penetrations to be used in each ice blowing evolution.
The importance of not using penetration M-371 during ice blowing activities
,V Catawba Nucl(ar Station Reply to a Notice of Violation 413, 414/91-13-01 4
while core alterations are in progress, will be included in the Refueling Outage 1
i Brienng Package for applicable Operation's personnel, All ice handlers will be required to be qualified to the Operations Training and Qualincation Guide on proper use of procedures per OMP l 4, Use of Procedures.
B.
Operations will evaluate formalizing a philosophy of valve verification following tagouts. --
Training associated with the implementation of modified R&R Sheets will convey the need for tailgate meetings and any changes to the philosophy of valve verification.
t C.
An Operations committee is reviewing all preplanned tagouts for the VA system.
This committee will provide recommendations and changes if needed.
_ Operators during requalification and the hot license class v.ill receive operator proficiency training concerning this incident.
D.
No further actions specifiS to this incident are planned.
E..
The Tagout Removal and Restoration (R&R) Procedure will be changed to require specifying a breaker position upon restoration.
5 Training will be conducted on changes to the R&R Procedure.
