$h ATTACHMENT 2 Further investigation into this incident has revealed that although repair per-sonnel were at the valves the majority of the time of the repair, these personnel were not at the valves continuously while the valves were inoperable. During the period of time the repair personnel were at the valves, telephone communication was available between the control room and the valves that would have allowed control room personnel to contact the repair personnel to manually close the other valve. The two valves are in series, and one valve was always capable of being manually closed.
With these factors in place, the conclusion is that while the violation did occur in that these two valves were not capable of automatic closure as designed, no loss of safety function would occur as it was always possible to close the valves manually before hydrogen binding of the pumps would occur thus maintaining the design safety function of the valves.
On this basis Duke Power believes that a Civil Penalty is not warranted in this case and requests mitigation of the proposed find.
