Statement of Violation
)-
During an NRC inspection conducted November 24,1996 through January 4,1997, a t
i violation ofNRC requirements was identi6ed. In accordance with the " General Statement i
of Policy and Procedures for NRC Enforcement Actions," (60 FR 34381; June 30,1995)
I the violation is listed below:
>
l
Callaway Plant Technical Speci6 cation 6.8.1 states, in part, that written procedures
)
i shall be established, implemented, and maintained covering the applicable procedures
recommended in Appendix A ofRegulatory Guide 1.33, Revision 2, February 1978.
l
!
Regulatory Guide 1.33, Appendix A,1.c requires, in part, that administrative procedures be written for equipment control tagging.
i Administrative Procedure ODP-ZZ-00310, " Workman's Protection Assurance
!
Tagging," Revision 2, Step 4.1.10.3, required that the method and order specified on
!
the tagout control sheet be followed when hanging tcgs.
a L
j Contrary to the above, on Deceminr 18,1996, the equipment operator pulled the
incorrect fuses when hanging a tag specified on Workman's Protection Assurance j
tagout control sheet 21672. This personnel error resulted in tripping a circulating l
water pump and a service water pump requiring a power reduction to avoid a turbine j
trip on loss ofvacuum (483/96014-01).
l This is a Severity Level IV violation (Supplement 1).
- -
l Reason for the Violation The cause of the violation was determined to be personnel error by a non-licensed j
Equipment Operr.or (EO) when placing Workman's Protection Assurance (WPA) tags j
for tagout control sheet 21672. It was determined the EO was working in cabinet PB12102 instead of PB12104 as speci6ed by the tagout control sheet. The EO thought he
]
l was pulling the secondary fuses for transformer XPB121, when in fact he was pulling the l-secondary fuses for bus PB122, which resulted in the trip of the 'B' circulating water pump and the 'B' service water pump.
Corrective Steps Taken and Results Achieved:
The 'A' Essential Service Water Pump was started to supply service water loads and licensed Reactor Operators reduced power to 92% to minimize the condenser pressure increase. The 'B' circulating water pump was restarted. Plant systems responded as expected. An Event Review Team was assembled. A corrective action document, SOS.
96-1992 was initiated to document and track corrective actions associated with this event.
WPA tagout 21672 was reviewed and veri 6ed to be correct.

Page 2 Corrective Steps to Avoid Further Violations:
The event was reviewed with EOs on shift. " Attention to Detail" was stressed for placement of WPA.
Operations requalification training cycle 97-0 willinclude use of a Stop, Thmk, Act, and Review (STAR) Trainer. This is a control panel simulator that is designed to challenge self checking performance. The simulator provides a hands-on approach to emphasize E
attention to detail in performance of tasks. Operations requalification training cycle 97-1 will include management expectations for placement of WPA as well as a review of this event.
Date when Full ComDiiance will be Achieved:
Full compliance will be achieved upon completion of Operations requalification training.
Training cycle 97-0 will be completed by March 15,1997. Training cycle 97-1 will be completed by May 1,1997.
