Statement of Violation:
' Technical Specification 6.8.1.a requires, in part, that written precedures be established,
implemented, and maintained conceming the applicable procedures recommended in
Appendix A of Regulatory Guide 1.33, Revision 2, Febtaary 1978. Regulatory Guide 1.33, Appendix A, Section 9.c.(l), states that procedures should include information on
the method for obtaining permission and clearance for work. This requirement is
implemented, in part, by Plant General Procedure OPGP03-ZO-EC01, Re.ision 6,
" Equipment Clearance Orders." This procedure requires that equipment clearance orders
shall provide adequate personnel and equipment safety.
Contrary to the above:
On June 24, Equipment Clearance Order 97-2-76518 failed to provide adequate personnel
and equipment safety in that Essential Cooling Water Screen Wash Booster Pump 2A
inadvenently started while the system was drained.
Also, on July 21, Equipment Clearance Order 97-1-71609 failed to provide adequate
personnel and equipment safety in that workers breached an unisolated component -
cooling water system pipe while performing maintenance on Residual Heat Removal
Pump 1B.-
This is a Severity Level IV violation (Supplement 1)(498;499/97005-03).
II.
South Texas Project Position:
South Texas Project concurs that the violation occurred.
III.'
Reason for the Violaticn:
The cause of the June 24, Unit 2 Screen Wash Booster Pump event was the failure of the
. Senior Reactor Operator to identify the additional relay contacts that actuate the Screen Wash
Booster Pump during his review of the Equipment Clearance Order for the Traveling Screen.
. The July 21, Unit 1 Residual Heat Removal event was caused by less than adequate
.
communications between the work package planner and the Equipment Clearance Order
preparer. In addition, the Equipment Clearance Order acceptor did not perform an adequate
. walkdown verification.
